BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the steps of a vacuum pump intelligent cleaning method of the present invention; Figure 2 It is a structural schematic diagram of a vacuum pump intelligent cleaning system of the present invention. DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] See also Figure 1-Figure 2 , the present invention provides a technical solution: See also Figure 1 In the first embodiment of the present invention, a vacuum pump intelligent cleaning method is provided. In the method, a liquid ring vacuum pump is used to create a vacuum drying, vacuum filtration and other environments for chemical production, the operating state of the vacuum pump is monitored, and it is determined whether the vacuum pump needs to be cleaned to prevent the dirt in the vacuum pump from affecting the operation of the vacuum pump and improve the production efficiency. The method includes the following steps: S10. Monitor the operating status of the vacuum pump and collect operating data during the operation of the vacuum pump; the operating data includes the operating cycle of the vacuum pump, the gas pressure in the vacuum pump and the working fluid temperature; collect parameter data of the detergent during the cleaning process of the vacuum pump; the parameter data includes the amount of detergent used and the concentration of the detergent before and after cleaning.

[0013] Furthermore, the timestamps of the start and end of the vacuum pump operation are recorded, and the vacuum pump operation cycle is determined based on the recorded timestamps; the vacuum pump is a liquid ring vacuum pump; the gas pressure in the vacuum pump represents the gas pressure in the pump body of the liquid ring vacuum pump; the working fluid temperature in the vacuum pump represents the working fluid temperature in the pump body of the liquid ring vacuum pump.

[0014] It should be noted that when the liquid ring vacuum pump starts operating, the impeller and rotor in the vacuum pump are controlled to rotate. Due to the action of centrifugal force, the working fluid is thrown to the surroundings of the pump body to form a liquid ring close to the inner wall of the pump body. As the impeller rotates, the gas in the pumped system is sucked into the working chamber and is continuously compressed and discharged out of the vacuum pump. Due to the large amount of heat generated when the gas in the vacuum pump is compressed, the temperature of the working fluid rises, the liquid concentrates and impurities precipitate, and the metal in the vacuum pump oxidizes. The drastic changes in temperature and pressure in the vacuum pump will accelerate the precipitation of impurities and the oxidation process of metals in the vacuum pump, thereby causing the formation and accumulation of dirt in the vacuum pump.

[0015] In this embodiment, the collected gas pressure and working fluid temperature in the vacuum pump are the gas pressure and working fluid temperature near the gas outlet in the liquid ring vacuum pump; the working fluid is water.

[0016] Furthermore, the method for cleaning the vacuum pump is as follows: before cleaning the vacuum pump, open the drain valve of the vacuum pump to discharge the working fluid in the vacuum pump; after the working fluid in the vacuum pump is discharged, close the drain valve, inject detergent into the air inlet of the vacuum pump to clean the vacuum pump, and determine the amount of detergent injected and the concentration of the detergent before cleaning; after cleaning the vacuum pump, open the drain valve of the vacuum pump to discharge the detergent after cleaning, and determine the concentration of the detergent after cleaning; wherein, record the parameter data each time the vacuum pump is cleaned, and determine the number of cleanings n of the vacuum pump; and use the timestamp of this vacuum pump cleaning to the timestamp of the next vacuum pump cleaning as a vacuum pump maintenance cycle.

[0017] It should be noted that the liquid ring vacuum pump contains an inlet valve, a drain valve, an air inlet and an exhaust port. When the vacuum pump is cleaned, the water inlet valve, the drain valve, the air inlet and the exhaust port are all closed; the water inlet valve is used to inject working fluid into the vacuum pump; the drain valve is used to discharge the working fluid and detergent in the vacuum pump; the air inlet is used to inhale the pumped system gas and inject detergent; the exhaust port is used to discharge the compressed gas; since the air inlet is directly connected to the vacuum pump cavity, the cleaning agent injected from the air inlet can more directly and comprehensively contact the parts inside the pump that need to be cleaned, thereby improving the cleaning efficiency.

[0018] In this embodiment, the detergent is a citric acid solution, and the dirt in the vacuum pump is cleaned by chemically reacting the citric acid solution with the dirt in the vacuum pump.
