Analysis of Causes of Vacuum Pump Insufficiency and Remedy

I. Insufficient supply of vacuum pumps leads to insufficient speed; insufficient water supply; excessive clearance between the impeller and the distribution plate; leakage of water leakage due to mechanical seal damage; excess impeller wear;

If this happens, then the corresponding solution is: check the power supply voltage is within the rated voltage range of the motor; increase the amount of water supply (must be controlled within the correct range, otherwise it will lead to motor overload heat); small impeller and Distribution plate clearance (usually 0.15-0.20mm); change the mechanical seal; replace the impeller; check the outlet pipe

Second, the vacuum pump can not start or start the noise

Possible causes: The motor power supply voltage is insufficient; the motor runs out of phase; the pump is not used for a long time to cause corrosion; the debris is sucked in the pump;

If this happens, then the corresponding solution: check the power supply voltage is too low; check the motor wiring is solid; if the pump is not used for a long time to cause corrosion can add a little rust Remover or open the pump cover to artificially remove rust; Open the pump cover to remove debris; adjust the distance between the impeller and the distribution plate.

Third, the vacuum pump motor overheating problem

Possible causes: Overloading of the motor leads to overload of the motor, phase loss of the motor, blockage of the exhaust hole, and dragging of the impeller to other components.

Calcium Formate

Calcium Formate is white crystal powder,used as acidifying agent in all kinds of animal feeds, mildew preventive, antibacterial agent, effectively preventing diarrhea, could adjust the intestinal function to promote nutrients absorption. Food industrial additives, plant growth regulator.

It is also used as fast coagulant, early strength of the cement. Mainly used in building mortar and various concrete to speed up the hardening speed of cement and shorten the condensation time, especially in winter construction, to avoid the slow condensation speed at low temperatures. Decompression is fast, so that cement can be put into use as soon as possible.

For various kinds of dry mixing mortar, various kinds of concrete,wear-resisting material, floor industry.

As desulphurizing agent that can be used as a high sulphur fuel.

As leather industry auxiliaries, widely used in high-grade leather manufacturing.

Besides,it also can be used Oil Drilling Industry.
