Problems solved by technology

[0004] In order to achieve the purpose of the present invention: in order to solve the problems that arise during the use of the existing tester and optimize the system structure, we can only redesign a Roots pump that can realize water vapor generation, vaporization latent heat recovery and cycle operation performance under negative pressure conditions. tester
It is used to meet the test requirements of specimens, meet the urgent needs of national defense, and solve the defects in the use of existing testers, and can also fill a gap in the country

Abstract

The invention relates to a pump power test system, a vacuum pump, a test pump, a pressure vessel, a first water pump, a second water pump, a processing system, a first pressure sensor, a second pressure sensor, a weighing device and a water tank; The equipment is used for weighing the water pumped by the second water pump, and obtaining the weight data. The invention adopts the closed-loop control method of the processor to control the temperature of the water tank, the temperature control effect is stable, and the control accuracy is 1°C higher; the liquid in the water tank is heated in advance and then enters the pressure vessel, which solves the problem of the temperature disturbance of the liquid temperature during the test pump test, and eliminates the direct Leakage risk; use the processing system to test the measurement points of the whole system and control the operation of the test system, which improves the intelligent control of the system, enhances the reliability of the system operation, and is applicable to the long-term test of the test pump.

Description

technical field [0001] The invention relates to the technical field of hydraulic / pneumatic sealing, in particular to a pump power testing system. Background technique [0002] The pump is a fluid suction device, and the Roots pump is one of the core components of the fluid processing device. Its main function is to suck the water vapor evaporated from the low pressure, compress it and condense it after boosting the pressure, so as to achieve the increase of pressure through boosting. Water vapor, for the purpose of recovering the latent heat of vaporization of condensed water. [0003] The existing tester adopts an all-stainless steel system, the medium is added to the liquid before each test, the water vapor in the system is generated by electric heating, and the control of the test bench is a full manual adjustment mode. After the design of the tester is completed, it can meet the requirements of use. However, the following defects still appear during use: 1. It is diffic...
