Oxygen pressure reducing valve principle of work

In physical chemistry experiments, often use oxygen, nitrogen, hydrogen, argon and other gases. These gases are generally stored in a dedicated high-pressure gas cylinder. When using the pressure reducing valve to gas pressure drop to the required range of experiments, and then through the o

Wells operate well with submersible pumps

Water pump is mainly used in both flooding and oil immersion, both by the pump and motor composed of two parts. In order to ensure the normal operation of the pump, it must be carried out as follows.

1. Electric pump before use, the application of megger to check the mo

Global printing ink market grows less than 1%

Single screw pump selection skills

Selection of single screw pump specifications are based on the nature of the fluid being transported and flow, pressure to determine, and the pump speed by the viscosity and corrosive liquid delivery, as the main parameters to choose, in order to ensure reliable operation of the pump.
