The relationship between roots pumpcapacity and the pumping speed of the former pump depends on the volume efficiency and the pressure difference of the roots pump license. If the volume efficiency is low, the effective pumping speed of the roots pump system will decrease obviously. If the pressu...

Mould material is the material and technical foundation of mould manufacturing industry. The mould steel is the traditional mold material, its variety, specification and quality have a decisive effect on the performance, service life and manufacturing cycle of the mould. The die steel plate numbe...

Common causes of bearing fever during vacuum pump operation As the vacuum pump in high-speed operation will be formed, the rotor speed is too fast will form a bearing support rotor fever. Usually formed during the operation of the vacuum pump bearings overheating have the following reasons and va...

EVP Diffusion pump silicon oil use high quality base oil and imported additives deployment is a Ideal lubricating material, widely used in China’s military enterprises, display industry, lighting industry, solar industry, coating industry, refrigeration industry. Performance: Extremely low ...

1.The features for vacuum system of vacuum distillation plant (1) Must be able to remove steam and other various distillate discharge of steam; (2)Vacuum systems for industrial vacuum distillation equipment need to have a larger pumping capacity, can extract the gas at higher temperatures; (3)Vac...

Vacuum distillation is one of the distillation methods under reduced pressure. It is generally used to separate substances that are easily decomposed or polymerized when heated to boiling under atmospheric pressure or to combine with other distillation methods such as steam distillation to lower ...

Roots pump, also named as roots booster, its main function is increasing vacuum pressure. Single roots pump can reach 5*10-2Pa, suitable for application with working pressure ranging 103~10-1Pa. But traditional roots pump cannot be started separatly, it should be supported by mechanical pump (als...
