In the face of the continuous promotion of market competitiveness and the development of its advantages and capabilities in all aspects, it is necessary to increase the promotion of its advantages and capabilities in all aspects according to the actual characteristics of piston vacuum pump, with reliable product application strength, according to the effective exertion of the overall application strength, to enhance the continuous improvement of its application advantages in all aspects, and with reliable product application effect to promote the development of actual performance Exhibition, reflecting the effective play of the overall application performance, so as to increase the overall promotion of all aspects of application advantages. So, what is the application of piston vacuum pump in industry?
The piston vacuum pump is composed of top cover, valve plate, cylinder, casing, piston skin ring, connecting rod assembly, cooling fan, fan cover, silencing equipment, shockproof feet and other structures.
Successful application of piston vacuum pump in coal tar distillation industry
As the temperature at the outlet of the heating furnace is significantly lower than that of atmospheric distillation after the decompression distillation of coal tar is adopted, the system operation temperature is reduced, the hydrogenation, decomposition and polymerization of tar components are prevented, the tar components are stable, and the gas is saved at the same time; the yield of naphthalene is obviously improved by cutting out the three mixed components; the quality of asphalt is stable, and the change range of softening point is small; no direct steam is needed at the bottom of the tower, and the steam is used At the same time, the production of some waste water is reduced.
The vacuum system provides the negative pressure required by the coal tar distillation process. The key part of vacuum system is piston vacuum pump. The mechanical pump is vacuumized by the principle of mechanical pumping, which is composed of stator, rotor, rotor, etc. the mechanical pump generally has a low degree of vacuumization.

Therefore, piston vacuum pump is widely used in coal tar processing industry.
