Gas transfer pump occupies a very important position

Pump plays an important role in the petrochemical plant, known as the device heart said gas transfer pump operation is stable and reliable, not only the normal production of the device is very important, the long period operation of equipment, energy saving is also of great petrol dispenser pump significance to ensure the therefore, the steady and safe operation of equipment is one of the main contents of maintenance repair work of the most common fault phenomena of vibration gas transfer pump, analyses and puts forward the way of vibration, in order to further improve the level of maintenance and repair work.With the operation and the fuel transfer hand pump oil circulating gas transfer pump, in return for high vacuum end will re evaporated into steam. Will affect the gas transfer pump, increase the pump oil pollution. Set the gas ballast valve can effectively prevent the condensation of condensable gases, namely the gas transfer pump in the compression process, gas ballast valve through the gas hole of the permanent dry gas mixed with compressed gas, condensable gas partial pressure in the pump when the temperature reaches the saturation vapor pressure, pressure of compressed gas can reach exhaust pressure, exhaust valve is opened, the condensate and dry gas discharged simultaneously.The difference between single-stage and two-stage diesel transfer pump is a two-stage pump can obtain a higher vacuum. In the two-stage pump, when the presence of low-level and high-vacuum chamber vacuum level range, you need to set up catching rabbits auxiliary exhaust valve. When the auxiliary exhaust valve is aimed at higher inlet pressures.
