Rotary Vane Vacuum Pump Product Introduction
Rotary Vane Vacuum Pump Product Introduction
The rotary vane vacuum pump is one of the basic devices used to evacuate a sealed container. It can be used alone or as a fore pump for booster pumps, diffusion pumps, molecular pumps, etc., to maintain pumps, pre-pumps for titanium pumps. Can be used in electric vacuum device manufacturing, thermos manufacturing, vacuum welding, printing, plastic, refrigeration equipment repair and instrumentation. Because it has the advantages of small size, light weight and low sound, it is more suitable for use in the laboratory.
Features of rotary vane vacuum pump

1. Small size, light weight and low noise;
2. It is equipped with a gas ballast valve, which can remove a small amount of water vapor; it can allow long-term continuous operation under the conditions of ambient temperature of five degrees Celsius to forty degrees Celsius and pressure less than 1.3X103 Pa, and the relative humidity of the pumped gas is greater than 90%. Open the gas ballast valve.
3. With automatic anti-return oil check valve, easy to start;
4. The air inlet should be continuously operated in the atmosphere for no more than one minute.;
5. Not suitable for the removal of gases that are corrosive to metals, chemically reactive to pump oil, gases containing particulate dust, and oxygen-containing, explosive, toxic gases.

Application range of rotary vane vacuum pump

Gas type: Clean and dry air without other mixture at normal temperature. Air with other dust and moisture is not allowed.
Working requirements: The continuous working time of the imported pressure is greater than 6500Pa, and should not exceed 3 minutes to avoid pumping caused by fuel injection.
Job requirements: The inlet pressure is allowed to work continuously for a long period of time under the condition of less than 1330pa.
Ambient temperature: Vacuum pumps are generally used in environments with a room temperature of not less than 5 ° C and a relative humidity of not more than 90%.

Product parameters of rotary vane vacuum pump

Q:What is the reason for circulating water to use the vacuum pump to go out from the pump? It is not the reason that the switch is turned off and then the rubber tube is pulled out after the suction filtration, but the water goes out during the suction filtration process.

A:Close the inlet valve of the working fluid inlet a little. The reason is: because the water inlet is too large, the water ring is too thick, and part of the water is discharged from the exhaust port.

Q:Circulating water multi-purpose vacuum pumps have a small drainage volume and can't get the degree of vacuum. What is the reason?

A:Please carefully check the seals of the pump for air leaks, pipeline connections, etc. If these are normal and intact, check the pump's own problems, whether the pump motor is reversed, and whether the valves are all open Is the vacuum degree of the pump working not enough to achieve the required vacuum degree?
