Rotary vane vacuum pump used in coal chemical process _

in order to improve the coordination ability and efficiency of equipment, vacuum equipment ( Rotary vane vacuum pump) Gradually seriation and its configuration, complete, in order to better meet the needs of the production safety of the coal industry and the development direction of future vacuum pump products. With the development of the coal industry technology, the various applications in the field of the design of the rotary vane vacuum pump has been improved, for the safety of the coal industry, energy saving and environmental protection made an important contribution. In the design and manufacturing, highlights the application advantages in the process of rotary vane vacuum water pump in coal chemical industry.

typical coking plant usually includes coal preparation plant, coking plant, recycling workshop, tar processing workshops, benzene processing workshops, and waste water treatment plant desulfurization plant. CBM can synthesize many chemical products of raw materials, such as ammonia, methanol and formaldehyde. Rotary vane vacuum pump is a device to solve the problem of the process, such as stress, pressure and synthetic distillation.

configuration design of water ring pump gas separator with special design, the related instrument consisting of a vacuum pumping gas compressor unit to ensure no leakage. Due to the use of water or other liquid as working fluid, it can take away heat compression and connected to the isothermal compression process, it is particularly suited to the extraction and the pressurization of the flammable and explosive gas.

it has its own characteristics of explosion-proof: in order to meet the needs of the coal industry safety in production, more professional services to the coal industry. The design of the rotary vane vacuum water pump has the characteristics of fire extinguishing seedlings. Therefore, the use of rotary vane vacuum pump as the gas emission and transport, eliminates the explosion-proof device. Such facilities, the advantage is obvious, mainly reflected in: 1. Facilities to simplify; 2. Water saving; 3. Reduce monitoring; 4. Complete the explosion-proof function. Patented vacuum check valve between the vacuum pump suction and system. When abnormal downtime, system and vacuum pump can be fully automatic switching, has the function of preventing backwater and tempering.

the pump itself has a check valve, a gas ballast valve ( Optional) , an outlet filter, a return pipe and an oil cooling circuits. flange motor driven by directly. Installed in the pump body has three eccentric rotor blades, the blade will pump into three separate rooms, each compartment volume changes periodically with the rotation of the rotor.

when the rotor rotates, the volume of inlet part of the pump cavity, the gas from the air inlet suction, gas through the air filter element, open the backflow into the cavity of the pump. When the rotor rotates, further vane pump chamber part is separated from suction. This part of the pump chamber volume and gas is compressed. Under the pressure of gas in slightly higher than the atmospheric pressure pump chamber through the exhaust valve left.

the oil injection pump chamber to carry on the seal, lubrication and cooling pump. By the compressed gas entrained oil first captured by folding in the jar. Then in the export of mist separator filter completely. Therefore, the oil content in the exhaust dropped to below the visible level.

oil seal rotary vane vacuum pump is widely used in vacuum engineering fields, including industrial production and research and development, can be used in the manufacture of rough and medium vacuum environment. It can be used alone, also can be a backing pump or drainage pump used for other high vacuum pumps or ultra high vacuum pump.

the personalized characteristic of coal chemical engineering with rotary vane vacuum pump is obvious: in view of coal mine gas outburst and the safety requirements of coal and gas outburst, the development and production of Marine pump can effectively solve the above problems. Rotary vane vacuum pump in the process of coal chemical industry main features: 1. Small volume, flexible movement; 2. Perfect protection measures; 3. The special requirements of underground coal mine; 4. Can use a large amount of water vapor and microscopic solid pumping. Particles of gas more powerful.
