Solve the vacuum pump stuck three ways

Oil pump vacuum pump oil is used to lubricate the vacuum pump, vacuum pump oil inside the rotary vane pump not only play a role in lubrication, but also play a sealing role, vacuum pump pressure and flow are to rely on the normal operation of vacuum pump oil To guarantee. Vacuum pump oil in operation, through the vacuum pump to the tank inside the vacuum pump oil to the pump body, which runs through the pump back to the tank through the return pipe inside, because the vacuum pump operation temperature will reach 70-105 degrees, part of the vacuum pump oil Will become oil and gas, with the exhaust to the exhaust port, through the failure of the oil mist separator (exhaust filter) over, back to the vacuum pump tank. To ensure that the vacuum pump is not stuck due to lack of oil, we must ensure that enough vacuum pump oil, pipe patency, vacuum pump oil is not emulsified, no sludge can flow inside the vacuum pump. Three ways to solve the vacuum pump stuck to prevent the vacuum pump stuck method: 1, regular replacement of vacuum pump oil, according to different industries, the quality of vacuum pump oil, and to develop different replacement cycle, in general 700 --- 3000 hours a replacement, At the same time, we also need to change Puxu vacuum pump oil filter, pay attention to, every time to replace the vacuum pump oil to completely replace the vacuum pump oil, do not just add. 2, regular cleaning vacuum pump tubing. 3, regularly replace the vacuum pump oil mist separator, commonly known as the exhaust filter to prevent the vacuum pump with the exhaust gas exhaust pump, resulting in reduced vacuum pump oil.

carbohydrazide can act as an oxygen scavenger to prevent corrosion, especially in boiler feedwater systems, rocket propellant assemblies, color image and soap stabilizers, antioxidant rubber, boiler water deoxidizers and metal passivators. Carbohydrazide can also be used as an anticorrosive agent. Organic synthesis of intermediates.
