Vacuum pump performance testing system and method based on cloud technology

Abstract

The invention relates to a vacuum pump performance testing system and method based on the cloud technology. An air inlet pipe is connected with an air inlet of a testing cover, and a flow meter is arranged on the air inlet pipe. A vacuum meter is arranged on the testing cover, an air outlet of the testing cover is connected with a reducing connector, the reducing connector is connected with one end of a corrugated pipe, the other end of the corrugated pipe is connected with an air inlet of a to-be-tested vacuum pump, an air outlet of the to-be-tested vacuum pump is connected with an exhaust pipe, and an exhaust silencer is arranged at the tail end of the exhaust pipe. A data collection card is in communication connection with the flow meter and the vacuum meter and is used for collecting signal data of the flow meter and the vacuum meter. A cloud server is in communication connection with the data collection card and is used for receiving the signal data sent by the data collection card and storing and processing the signal data. Through the testing system, testing flexibility and testing efficiency of the vacuum pump are improved, and cost is reduced; and meanwhile, data cloud storage and cloud processing can be achieved, good transportability and universality are achieved, and the vacuum pump performance testing system and method are suitable for testing requirements of different kinds of vacuum pumps.

Description

technical field [0001] The present invention relates to the technical field of pump testing, in particular to a vacuum pump performance testing system and method based on cloud technology. Background technique [0002] With the rapid development of my country's microelectronics, semiconductor, pharmaceutical, precision manufacturing, chemical and other industries in recent years, the demand for vacuum pumping in these companies has continued to expand, and it is used in waste gas treatment, process vacuum, gas replenishment and gas-liquid transmission. Vacuum pumps are also Because of their different application fields, they are divided into Roots pumps, rotary vane pumps, screw pumps, molecular pumps, etc. Different vacuum pumps correspond to different requirements for vacuum degree and vacuum pumping speed. Enterprises have higher requirements for vacuum degree and vacuum pumping speed of vacuum pumps. Therefore, the vacuum pump manufacturer is often required to provide the ...

Problems solved by technology

[0002] With the rapid development of my country's microelectronics, semiconductor, pharmaceutical, precision manufacturing, chemical and other industries in recent years, the demand for vacuum pumping in these companies has continued to expand, and it is used in waste gas treatment, process vacuum, gas replenishment and gas-liquid transmission. Vacuum pumps are also Because of their different application fields, they are divided into Roots pumps, rotary vane pumps, screw pumps, molecular pumps, etc. Different vacuum pumps correspond to different requirements for vacuum degree and vacuum pumping speed. Enterprises have higher requirements for vacuum degree and vacuum pumping speed of vacuum pumps. Therefore, the vacuum pump manufacturer is often required to provide the performance curve of the vacuum pump. At this time, the corresponding test system is required to test the performance of the vacuum pump. However, the existing vacuum pump performance test system has problems in the process of testing different types of vacuum pumps. Disadvantages of inconvenient use, poor versatility, low detection efficiency, and imperfect test data management

[0003] For example, the invention patent with the authorized notification number CN102734147B: vacuum pump performance comprehensive test system and method, the test system includes a control unit, at least one drive unit and at least one detection unit, although the test system has the advantages of high precision, comprehensive functions and high efficiency , but its control unit is to use the upper computer and the lower computer, the upper computer and the lower computer are connected by data lines, the lower computer includes PLC, input and output devices, multiple analog-to-digital converters and multiple photoelectric isolators, when testing vacuum pumps of different specifications When adjusting the parameters, it is necessary to adjust various parameters. When adjusting the parameters of this type of test system, it can only be operated on the PC side of the upper computer, which has the disadvantages of single control mode, imperfect test data management, and low test efficiency.

Another example is the invention patent with the authorized notification number CN105736349B: Roots vacuum pump performance test system and its test method, which discloses a device suitable for performance testing of Roots vacuum pumps, which has the disadvantage of poor versatility
