Professional vacuum pump manufacturers

There are many vacuum pump manufacturers, but not many professional, Shanghai EVP professional vacuum pump manufacturers produce a variety of vacuum products widely used in aviation, aerospace, atomic energy, military industry, electronics, chemical industry, metallurgy, textiles, food, medicine, environmental protection and other high-tech fields.

Vacuum pumps use mechanical, physical, chemical, physical and chemical methods such as container extraction, acquisition and maintenance of vacuum equipment. Vacuum pumps and other equipment (such as vacuum containers, vacuum valves, vacuum measuring instruments, connecting pipes, etc.) form a vacuum system, which is widely used in electronics, metallurgy, chemical industry, food, machinery, medicine, aerospace and other departments.

(1) Vacuum pipe and joint leakage is a common fault, so we need to pay attention to the pipe and pipe joint in daily use, hand rotating vacuum pump, try to vacuum pump flexibility, to ensure that these places are not loose.

(2) Add bearing lubricating oil to the bearing body and observe the oil level at the center line of the oil mark. The lubricating oil should be replaced or supplemented in time.

(3) unscrew the water plugs of the vacuum pump body and pour water (or pulp) into it.

(4) close the gate valve and outlet pressure gauge of the outlet pipe and import vacuum gauge.

(5) point motor, see if the motor is turning correctly.

(6) try to control the flow and lift of the vacuum pump on the label.

(7) Start the motor, when the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump, as it shows the appropriate pressure, gradually open the gate valve, while checking the load of the motor.

(8) During the operation of the vacuum pump, the bearing temperature should not exceed the ambient temperature of 35C, and the maximum temperature should not exceed 80C.

(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.

(10) when the vacuum pump is stopped, shut down the gate valve and pressure gauge first, then stop the motor.

(11) Vacuum pump in the first month of work, after 100 hours to replace lubricant, after each 500 hours, oil change once.

(12) regularly check the wear of the axle sleeve, and replace it in time when the wear is large.

(13) Regularly adjust the packing cap to ensure the normal dripping condition in the packing chamber (suitable for dripping leakage).

(14) Seasonality also has a certain impact on the pump, such as oil-sealed pumping, summer is best to use high-temperature viscosity in accordance with the requirements of lubricant, water ring pump in winter, after shutdown, the lower part of the pump body need to be unscrewed to release the media. Prevent frost crack.

(15) In the vacuum pump in a long-term shutdown state, if necessary can be removed from the pump on the rotating parts and joints to do a protective treatment, such as the use of grease smear, installed, preserved.
