Working Principle of Vacuum Assist Pump and Maintenance Matters
The vacuum assist pump is a kind of pneumatic vacuum pump, which is a kind of pump used to suck and store vacuum. It is driven by compressed air to extract gases and vapors by compression and compression. It is mainly used in pressure testing, chemical reagents, food preparation, medical applications and vacuum operation of other equipment. The principle of the vacuum assist pump is mainly as follows.
The vacuum assist pump is composed of a vacuum pump and a vacuum pump, and compressed air is used as the power source to start the vacuum assist pump. The working principle of the vacuum pump is to form a vacuum chamber, put the air intake pipe into the vacuum chamber, and pinch the air intake pipe by the air intake valve of the vacuum pump. Press the start button and the vacuum pump starts working. The closed chamber with the closed valve of the air clamp is in a vacuum sealed state under the action of the vacuum pump, and the gas and steam in the enclosed cavity is extracted, compressed and discharged from the outlet pipe. The vacuum pump works continuously and the gas and vapor can be extracted in the chamber to form a vacuum. When the vacuum reaches a preset value, the pump stops working and the inlet and outlet valves are closed, and the environment in the chamber is still in a vacuum.
In the process of using the vacuum assist pump, it is necessary to pay attention to the maintenance work. The following items need to be maintained and replaced in time. Firstly, when the industry environment is harsh and the amount of dust is large, regular cleaning of the pump should be carried out, which can prolong its service life. Secondly, when the output performance of the vacuum pump is reduced, some parts will wear out, so it is necessary to check and replace them regularly. Thirdly, the vacuum pump is equipped with oil seals, so it is necessary to check and replace them regularly. Fourthly, the vacuum pump should be stored in a cool, ventilated, dry and clean place. Finally, all parts of the pump must be lubricated regularly to ensure its normal operation.
In short, the working principle of vacuum assist pump is to form a vacuum chamber, put the air intake pipe into the vacuum chamber and compress the gas and steam in the enclosed cavity by the vacuum pump. In the process of use and maintenance, the dust cleaning in the environment, the timely replacement of worn parts, regular oil seal check and replacement, appropriate storage and lubrication are all necessary conditions to ensure the normal operation of the vacuum assist pump.
