1、 Screw vacuum pump - regularly remove grease and damaged parts

The internal key components of screw vacuum pump are vortex, worm gear, guide slide and new piston rod. Damage to these components will cause the total flow of the screw vacuum pump to decrease or be negligible. Solution: regularly remove grease, damage and clean the hydraulic chamber.

2、 Screw vacuum pump - standard safe operation procedure

1. strictly implement the startup and shutdown of screw vacuum pump for actual operation. At startup, zero output is turned on, and when the outlet value of the screw vacuum pump reaches the working pressure, the pressurization chamber is filled with nitrogen.

2. prevent the diaphragm from deforming due to nitrogen filling, avoid diaphragm rupture, and slowly increase the output of pump screw vacuum. When the pump stops running, the output of the screw vacuum pump shall also be slowed down.

3、 Screw vacuum pump - lift pump maintenance

1. carry out regular safety inspection during the operation of screw vacuum pump to check the amount of lubricating grease, the sound of machine pump, the working pressure of outlet value, the working pressure of hydrogen buffer tank, etc.

2. regularly replace the diaphragm of the screw vacuum pump shell and the diaphragm of the hydrogen buffer tank to avoid damaging the two screw vacuum pumps, resulting in the safety accident of stopping the metal catalyst.

Scaling of screw vacuum pump

Due to the working substance of screw vacuum pump (i.e. make-up liquid), the key is to immediately use drinking water or paper mill water. Due to the high hardness of tap water, the ionization composition of the alloy in purified water is also very complex. Therefore, the internal two-phase flow components of screw vacuum pump work under this material standard. After a long period of physical treatment, dirt will be generated and dirt will be generated. It will damage the screw vacuum pump to make it work normally.

The vacuum degree of the scaled screw vacuum pump will be reduced. Because there is dirt in the middle of the wind turbine and in the middle of the inlet and relief valve dialog boxes, the volume of the seal chamber becomes smaller, and the volume state of the inlet and outlet steam gas is also reduced. When the space between the blades is basically full of scale, or the dialog box of the pressure relief valve is basically full of scale, the displacement is basically zero, and the screw vacuum pump disappears and the vacuum is removed.

The polluted screw vacuum pump will not only reduce the vacuum degree, but also increase the power. Due to the formation of scale, the pressure relief valve dialog box becomes smaller, and when the dialog box is not included, the compression ratio in the small room increases, resulting in an increase in power and an increase in power of about 10%.

For screw vacuum pumping equipment, if there is too much dirt, it will endanger the working efficiency and service life of screw vacuum pump. Therefore, please protect the screw vacuum pump to prevent equipment damage.
