Frequently Asked Questions about H-Type and 2H-Type Slide Valve Vacuum Pump Series
- How to select the appropriate model of H-type and 2H-type slide valve vacuum pump series for aerospace hard coating applications?
According to the vacuum requirements of the hard coating process, if a high vacuum degree of 2Pa is required, select a model in the 2H-type series that meets this pressure requirement and has a pumping speed suitable for the coating equipment. At the same time, consider factors such as equipment installation space and power configuration.
- How to ensure the accuracy of detection in the sealing detection of the refrigeration industry by H-type and 2H-type slide valve vacuum pump series?
Ensure that the vacuum pump operates stably to reach the set vacuum degree, regularly calibrate the vacuum measuring instruments, and strictly follow the detection process flow to ensure the accurate and reliable sealing detection of the refrigeration system.
- What is the impact of the pumping speed of H-type and 2H-type slide valve vacuum pump series on industrial production?
A fast pumping speed can shorten the production cycle and improve production efficiency. For processes that require a rapid establishment of a vacuum environment, such as aerospace coating, an appropriate pumping speed is crucial.
- What are the differences in the ultimate pressure of H-type and 2H-type slide valve vacuum pump series in different industry applications?
In industries with extremely high vacuum requirements, such as aerospace, an ultimate pressure as low as 2Pa is required; while in some ordinary industrial applications, an ultimate pressure of around 6.5Pa may meet the needs, depending on the requirements of the process for the vacuum environment.
- How to choose the cooling method of H-type and 2H-type slide valve vacuum pump series?
If the working environment has good heat dissipation conditions and there are restrictions on the equipment installation space, air - cooling can be selected; if the equipment operates continuously for a long time and generates a large amount of heat, the water - cooling method can better ensure the stable operation of the vacuum pump.
- What issues need to be noted during the installation of H-type and 2H-type slide valve vacuum pump series?
During installation, ensure that the pump is placed horizontally, the connecting pipelines are well - sealed to avoid air leakage affecting the vacuum degree, and also consider the maintenance space of the equipment for convenient later maintenance and repair.
- What should be done if the H-type and 2H-type slide valve vacuum pump series produce excessive noise during operation?
Check whether the internal parts of the pump are worn, such as the slide valve and bearings; check whether the motor is operating normally; confirm whether the equipment is installed firmly and there is no looseness; and check whether there are foreign objects blocking the air inlet, and carry out maintenance or treatment according to specific problems.
- How to conduct daily maintenance of H-type and 2H-type slide valve vacuum pump series?
Regularly check the oil level and oil quality of the vacuum pump, and replace the deteriorated vacuum pump oil in a timely manner; clean the filters at the air inlet and outlet; and check the tightness of the seals, and replace them in time if they are damaged.
- What are the reasons why the vacuum degree of H-type and 2H-type slide valve vacuum pump series cannot meet the requirements during use?
Possible reasons include aging and air leakage of the seals, increased wear clearance of the internal parts of the pump, blockage of the air inlet or outlet, insufficient or deteriorated vacuum pump oil, etc., and these need to be investigated and resolved one by one.
- What factors affect the service life of H-type and 2H-type slide valve vacuum pump series?
Factors such as the frequency of use, working environment, maintenance conditions, and process media will all affect their service life. Rational use and regular maintenance can extend the service life of the vacuum pump.
