Do you know the basic knowledge of explosion-proof tools?

The raw materials of explosion-proof tools are mainly beryllium bronze and aluminum bronze. The beryllium bronze alloy and aluminum bronze alloy do not produce sparks during impact or friction. They are very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic and corrosive situations. BeA-20C alloy withstands 561IJ impact energy in air oxygen containing 30% hydrogen or 6.5-10% methane for 20 times without spark and combustion. The main functions of explosion-proof tools are: knocking, collision, falling hammer, impact, etc. will not spark, but explosion-proof media are not corrosion resistant in all cases. For example, in wet ammonia, some ammonium salts, acetylene, wet fluorine, chlorine, ammonium chromium, some dichromate, potassium hydride and other media, the degree of corrosion is quite large. And some media will react with copper alloy after contact, Explosion-proof materials with high risk are generated, such as acetylene steel produced by the combination of acetylene and steel. Under the above conditions, explosion-proof materials should be used in a dry environment as much as possible. After the completion of daily work, explosion-proof tools must have a proper maintenance stage, which plays a key role in the life of the tools, because if the maintenance of explosion-proof tools is not proper, our tools can not serve us for a long time. First of all, we should put the tools in a dry place to keep some parts of the work from being damaged.

Structure and working principle of explosion-proof hand oil pump

Explosion-proof hand oil pump is one of the conventional lifting oil pumps. This product cannot be used for the installation of liquid corrosive to metal. The pipe thread should be coated with a little magnetic oil and tightened to maintain the seal. Before use, a small amount of oil should be poured into the pump for lubrication, and then rotate the crank to pump oil. Add a small amount of lubricating oil into the pump after use. The explosion-proof hand oil pump is easy to operate. The gear driven by hand is suitable for conveying various oils, such as heavy oil, diesel oil and lubricating oil. The copper gear can be used to convey low internal point liquids, such as gasoline, benzene, etc. At the same time, it can be suitable for those containing hard particles or fibers, and is suitable for various viscosities, with good self-priming property. However, it is not necessary to fill liquid before starting the pump each time. The main structure of the explosion-proof hand oil pump is composed of the plunger of the oil suction, the oil inlet valve, the oil outlet valve and the pressure relief valve group. The sealing space formed by the closure of the plunger and the oil inlet and outlet valve is the working chamber of the oil pump. When the plunger moves upward, the volume of the working chamber becomes smaller and larger, and the pressure in the chamber is lower than the atmospheric pressure, the oil enters the working chamber through the oil filter screen. When the plunger moves downward, the volume of the working chamber becomes smaller and smaller, When the oil pressure in the working chamber rises, the oil outlet valve is opened, and the pressure oil is discharged into the oil circuit system for the emergency cut-off valve to open. The pressure relief valve is set for the pressure relief of the pressure oil circuit system. It is required to install a pressure relief valve to close when working. When the oil circuit system needs pressure relief, the pressure relief valve is opened, that is, the emergency cut-off valve is closed. The oil tank of the pump is in the outer casing cavity of the pump. When filling oil, open the oil filling plug on the upper cover. If the oil tank volume is insufficient, connect the auxiliary oil tank externally.

Explosion-proof F wrench non-sparking tool

Explosion-proof F wrenches have various names, some of which are valve wrenches, cocker wrenches, valve hooks, valve F wrenches, etc. They are mainly used to open and close various manual valves, generally divided into two types: anti-slip F wrenches and ordinary F wrenches. Its use features: convenient, light and versatile. The following points must be paid attention to when the explosion-proof F wrench is used to open and close the valve: A. Before the operation of the explosion-proof F wrench, the appropriate F hook wrench should be selected according to the regulations for the valves of different sizes. It is strictly prohibited to use an extension lever or a long wrench to pull the small size valve, because the design of the manual valve is mainly designed by ordinary manpower, The strength of the valve sealing surface and the closing force of the valve should be considered before operation. B. The opening and closing of the valve should be steady, and the force should not be strong or fast, especially the closing and opening of some high-pressure valves. C. When opening the steam valve, attention should also be paid: first, heat the steam valve in advance before opening, and drain the condensate. When opening, attention should also be paid to the need to use the F wrench to slowly open it to avoid water hammer. D. After all the valves are opened, use the F wrench to turn the handwheel a little to tighten the threads to avoid loosening and damage. E. For rising stem valves, remember the position of the valve rod when opening and closing. It is strictly prohibited to hit the dead center at the beginning of the whole process, and pay attention to check whether it is false closed when it is fully closed. F. When the pipeline is used in the initial stage, due to the large amount of dirt, or when the normally open valve is contaminated with dirt, the operator should use the valve hook to slowly open the valve, which is also slightly open, and use the high speed flow of the medium to wash away the dirt, then gently close it, then open it again, and repeat it for many times. G. When using explosion-proof F wrench to operate, if it is found that it is too laborious, immediately analyze the cause, and do not be reckless.
