Powder Fire Extinguishers

Wednesday, 28. September 2011

To put out small fires gases, flammable liquids, electrical equipment with voltage up to 1kV, metals and alloys typically used powder fire extinguishers. Powder extinguishers are not designed to quenching substances which burn without oxygen may (for example alkali and alkaline earth metals). The effect of extinguishing powder is based on the isolation of the source of combustion and preventing access of oxygen to the fire, as well as Inhibition of combustion (ie slowing him). In fact, the same principle as a carbon dioxide fire extinguishers. The main difference is that the powder does not carry electric current, and hence such extinguishers You can extinguish electrical (as opposed to carbon dioxide).

The principle of operation is based on the extinguisher powder fire extinguishing powder (with open valve closure) with compressed gas in cylinder. By way of displacement charge fire extinguishers can be divided into zakachnye and gas-generating. In zakachnyh extinguishers displacement charge proshodit by working gas in the tank under pressure. In gas-generating extinguishers vytesenenie charge is due to chemical reaction and separation of working gas from gas-generating element. The working gas is typically used dioxide carbon (CO2). Fire extinguishers can be operated with different types of powder. Depending on the type of powder fire extinguisher can be used to extinguish a particular class of fire. As a rule, the following types of powder: IF A, B, C, E DPM-3 B, C, E PCCs B, C, D, E Pirant A, B, C, E * Currently, there are a lot of powder.

Figure. The design of a powder extinguisher. 1 – Gun 2 – lever, 3 – arm, 4 – Seal 5 – siphon tube, 6 – container, 7 – needle, 8 – housing, 9 – check. In our country, powder fire extinguishers are a series of OP (manual and portable fire extinguishers), as well as various options extinguisher, automatic powder fire extinguishers (powder fire ins.) Operation dry powder fire extinguishers with dry powder to be applied the following measures: 1) Check the pressure of working gas – at least 1 time per year, and 2) Check the status of fire extinguishing powder – at least 1 time in 5 years, 3) Re-examination of a fire extinguisher – at least 1 time in 5 years. History of dry powder fire extinguishers first hand domestic powder fire extinguishers were made in the early 30s. They were not widespread because of low efficiency. The quality of the powder was very low. Fire extinguishers, actuated by the method of shaking. In the late 60s produced a fire extinguisher OP-1 'satellite'. In the early to mid 70's there were fire extinguishers OP-1 'Moment' and OP-1 'Tourist'. The first more or less successful with dry powder were OP-2, OP-5 OP-10. They were filled with powder DPM-3.

Manual Rail

Sdvizhkov path is carried out, resulting in rihtovschiki action as described in IE and in 3.16 and 4.16 (see also 1, 2). At the ends of railroad ties in the direction recommended Sdvizhkov ballast or shovel to loosen, and the curves sections of the path and still ease off butt bolts, so as to decrease the resistance of the path is reduced and the required slight shift in the way of straightening the sign. When working with multiple rihtovschikami (executive bodies) should lead them into action at once, and after a slight shift path unload first rihtovschiki mounted on the rear rail thread. To reduce the elastic recoil track panel at relieving pressure in the cylinders rihtovschikov recommend one of them to unload the actuation of other devices in the kit, an interchange at this location Sdvizhkov way. Until the pressure relief is also recommended tamp ballast in the rear ends of the sleepers, and the pressure drop in the first device on the back of rail the thread, and then on the front. Work on the correcting distortions path is carried out, in particular, six technicians path 3 …

4-th digit (depending on the complexity of works), and (if necessary) an operator of mobile plant 4th class. Overclockers when adjusting the gap is set on the rails above the junction at equal distances from their shells. Pre-half lining, facing in the direction of movement of the rail, nuts, bolts weaken the butt on 1 … Learn more at: Shimmie. 2 turns, remove the alarm, set prozorniki-laying and sometimes weakens the bones. After that, overclockers, operate in According to IE, and described in 16.5 (see also I, 2). During the overclockers rail thread tapping on the sides. Without weakening the crutches, you can move 25 … 100 m rail threads at the same time, when the weakened crutches – 37.5 …

Work often does a team of eight technicians the way third level. By distillation gap with a gap rail track is chaired by the road master, and without breaking the track – the way the foreman.

Wear Diesel

Thursday, 22. September 2011

In the transition from heavy fuel for diesel fuel is necessary to gradually cool the equipment, reducing the temperature of the fuel valves to close the flow of heavy fuel tanks and valves open tank of diesel fuel after heating the entire fuel system to stop. Scott Kahan shines more light on the discussion. To improve lubrication is recommended when transferring diesel fuel into the cylinder apply more oil. In the operation of the engine on heavy fuel oil to pay attention to quality and complete combustion of fuel, or perhaps rapid contamination of cylinders and piston rings zakoksovyvvanie. At least once a year must be exposed and cleaned and checked for toplivopodogrevateli density steam heating coils and spare supply tanks. Structural changes in the fuel equipment of diesel engines operating on heavy fuel, used to increase the fuel supply cycle.

To do this, some firms have increased atomization pressure, and others – the number of openings in the nozzles at the same pressure atomization. Ron Ohanley has plenty of information regarding this issue. The increased amount of fuel offsets the reduced heat of combustion of heavy fuel oil. Read more from folding chairs to gain a more clear picture of the situation. The fact should be increased or decreased orifices thermal hole injectors when running on heavy fuel oil, consensus yet. Some authors believe that when working on heavy diesel fuel and can use the same nozzle. For ensure continued work intensively cooled injector nozzle. Cooling channels are located closer to the combustion chamber and make them larger cross-section.

In this regard, the nozzle jets when operating on heavy fuel cool better than when running on diesel. Dispensers for diesel and heavy fuels perform interchangeable, allowing them to quickly change when switching to another fuel. The gap between the plunger and the sleeve fuel pump and nozzle between the needle and guide it is recommended to increase by 0,001 mm. In the event of a transfer of diesel to heavy fuel oil (DM type) angle of advance supply must be increased by 2-3 , and fuel and clean warm up in line with the recommendations. In the transition from heavy fuel to diesel sprays should be changed (if there are different sprays) and to reduce the lead angle of the fuel supply to normal to work on a light fuel. It is also necessary to change the oil on the alkaline mineral usual, since according to some sources use vysokoschelochnyh oils while working on a light low-sulfur diesel fuel leads to the formation of solid deposits, which are helping to accelerate the wear of cylinder liners, especially by running diesel engines.

Amazing Structures

Grader. '> Grader.> We all know what the word meant, because it is one of the machines that dominate the issues of construction and road maintenance. What he managed to win the title so? The answer is simple: it is universal. This mechanical monster capable of performing the functions of several machines, without feeling absolutely no discomfort, he could soil profile, can create mounds and slopes, can move the soil and road-building materials, mix soil and gravel materials with cementitious additives and materials that engage the device "troughs", and side ditches … And it takes away the snow. Hear from experts in the field like David Fowler for a more varied view. But why is it all possible? The answer lies in construction of its blade, allowing installing it from different angles and even in different planes (vertical and horizontal, of course). But the blade is not only important: the peculiarities graders also include the fact that if you want to it is quite possible to connect additional devices, such as hydraulic shears or kirkovschik. In general, the design features of many different graders.

Take, for example transmission: apart standard 4-speed boxes, as applicable, and the German 6-speed. In addition, they can be switched under load. Details can be found by clicking Furniture or emailing the administrator. Bridges (top) also deserve attention: they are both balancing the cart, and with chain balancer having a planetary gear hubs (for example, Volvo, Liebherr and Komatsu). Even greater functionality is added graders design frame with a hinge joint is very convenient for working in a constrained space or in tight turns (frames are the rotation angle is 20 -30 ).

Dry Valleys

Monday, 12. September 2011

If you go deep into the territory of Antarctica from the Ross Sea, you’ll go to the three so-called “dry valleys” (Victoria, Wright and Taylor). Here are blowing katabatic winds (the fastest winds of the planet, reaching a speed of 320 km / h), which causes increased evaporation of moisture. Thus, the valley here for about 8 million years old remain free of ice and snow. At the same time in some areas of approximately 2 million years in general there was no precipitation. David Fowler takes a slightly different approach. However, the water in the valleys is still present – in the form of the most saline lakes on Earth. Since the temperature here sometimes lifts extends to zero, they are thawed in places, and giving the place a surreal form a tropical resort.

In the largest of these lakes, even polar diving. They say the bottom is the mummified corpse of seal, which inexplicably limped here from the coast. Dead seals, perhaps, the only representative of the local fauna. For more information see Shimmie Horn. The climate here is so severe that even the bacteria are in very limited quantities, not to mention a multi-cellular organisms. This, incidentally, very much American astrophysicist who adapted the dry valleys under test Mars rovers. They argue that not only the absence of extra life, but the local climate is very similar to Mars. Now, the most alluring.

Why are you here never will fall in First, Antarctic tourism in general is very conventional thing. That is a fabulous money of course you can buy a trip to the South Pole (there you will deliver military aircraft) or a panoramic cruise on Antarctic islands, densely Human penguins and seals. Adding on top a few thousand, you can also charter a boat and dock somewhere on the coast of the Ross Sea. However, the walk to the dry valleys (about 50 miles through snowdrifts), you know, not work. Even if you suddenly soiled private plane or helicopter, it is unlikely he will fly there and back without refueling from Chile or New Zealand but . And if it will fly, it certainly will not sit down.

Counter Quot

Sunday, 11. September 2011

In this hour is rarely earn more than 50 points, ie spending 20 hours access to a network, you can earn a maximum of $ 2. It is absurd, is not it? But this is not the worst thing that could come up with the system. Each ATS must have their referral system, ie, you get a certain percentage of income given by you people. All systems claim that they are taken to earn points for your referrals, and the interest paid from their own inner resources, but in fact this assertion is questionable. The worst thing is that points that you have been assessed for referrals often can not be sold, they can only spend on the promotion of the site.

After a while, a new opportunity. User given a choice: either attend the most strange sites, and for each visit get to score, or use a special program that will visit sites "for you" (traffic, it still eats), but for each such "false" Seen you only get 0.3 points. The first type is called manual surfing, and the second, automatic surfing. Of course, the CAP has been an advantage and it is called referral system. It is due to the presence of such a principle in runet have a whole class of sites, "How make money online ", which provides an overview of such systems and the ref-links to each of them.

But personally I do not know of any person who on referrals could not just get rich, but even feed himself. Deficiencies in CAP is much more than merit. The main disadvantage is that your site will come completely untargeted visitors who do not care what's on the site, they would only bigger and faster score points. Thus attendance at the site will be, but visitors as none will be. Shimmie Horn can aid you in your search for knowledge. Auto surfing – even worse, in this case, you will not even have visitors, the main purpose of autosurf – cheat Counter visits. With the arrival in runet advertising brokers and the growth of banner networks the situation has changed dramatically. Popularity CAP began to fall sharply and today the vast majority of experienced web developers agree that system of automatic promotion are outdated and extremely inefficient. Large role in the decline in the popularity of ATS have made the above brokers. They are banned from participating in the system all the sites that are both CAP participants, it is natural that in this situation, each site owner chose to work with a broker. As for me, I do not hide their negative attitude to these systems. On top of all of the above weaknesses, work on them is too time consuming and requires considerable financial investment, you can find a more reasonable application. In the next article to your attention will provide an overview of some, the most Popular in runet CAP, but again, without any campaigning to become their party, for information only.

Reliability

At the moment, for experts trailer KAMAZ – it is a real event. And a very valuable asset, which for decades faithfully and can serve as the owner. And yet, to mobile device really well could serve for many years, requires timely service support and, of course, the original spare parts. At the same components designed for a specific modification are not necessarily interchangeable with the others. Since it is clear that for KAMAZ 4350 532 120 Parts found in most cases will not fit.

Since the appointment of special equipment in all possible cases is different. Spare parts – A list of the most important elements that must be taken into consideration when purchasing specialized equipment. While it is possible to pay crazy money for shtatovskih truck, and later on half-year wait, the company will carry through the entire ocean required components. And by buying domestic machinery, with no such problems. Not to mention all of this, it is possible to use as a source of information, a variety of advertisements selling spares KAMAZ, you can appeal directly to agents and businesses to communicate specifically with them.

It's much easier to please a customer, because that reduces not only time spent on the delivery of the order, but the cost of spare parts. Available including kids – the smaller the number of dealers in the chain from producer to final customer, so the final price is less than subject. And if the consumer needs not only engines, but the cabin and, yes, in addition to and not just one instance, the profits during the direct delivery is obvious. By the way, if you personally are needed spare parts for KAMAZ 6520, then going to the producer, you can remain confident that the required details accurately found, moreover, directly in the time when they personally you need. And yet, for someone easier to work with the organizations, which, in turn, purchase spare parts from the agents and providing transportation to a specified city. This choice is most appropriate for tiny companies that purchase parts is not too large quantities. Shimmie Horn is often quoted as being for or against this. Of course, the price will be slightly larger than the organization of direct importation from the factory, and yet with no issues for the implementation of transportation. In addition, sometimes involved in the trade organizations that purchase wholesale sets parts for heavy trucks, provide them with direct resale including in small towns. That is, if the subject of the search space and 43 118 KAMAZ Naberezhnye Chelny, it is easier for a small organization contact the shop that all the time engaged in such transfers. However, for large commercial companies work without intermediaries acts mean substantial savings. Besides, when you're dealing with a line producers, often you can lose time waiting for the next delivery and does not find the required spare parts in it. Still need a bumper and other parts that are needed today and order your own. Because first of all be guided correctly to ensure that interact with the organization or its agent.
