A sealing performance tester with temperature compensation function and sealing performance testing method

Abstract

The invention discloses a sealing performance tester with a temperature compensation function. The sealing performance tester comprises a sealing tank, a first collecting end, a second collecting end and a processing unit. The sealing tank is in a to-be-tested body and is made of materials which are good in heat conducting performance. The first collecting end comprises a first temperature sensor, a first vertical pressure sensor and a first pressure data source. The sealing tank is connected with the first temperature sensor and the first vertical pressure sensor. The first temperature sensor is connected with the processing unit. The first vertical pressure sensor is connected with the processing unit. The second collecting end comprises a second temperature sensor, a second vertical pressure sensor and a second pressure data source. The to-be-tested body is connected with the second temperature sensor and the second vertical pressure sensor. The second temperature sensor is electrically connected with the processing unit. The second vertical pressure sensor is connected with the processing unit. According to the sealing performance tester, the sealing tank is arranged in the to-be-tested body, air pressure of the to-be-tested body is boosted up to be the same as the air pressure of the sealing tank, the same temperature is achieved, and the problem that when the temperature of the to-be-tested body is read, error is large because of large environment temperature difference is avoided.

Description

technical field [0001] The invention relates to a sealing performance tester with temperature compensation function and a sealing performance testing method. Background technique [0002] At present, most of the sealing performance testing equipment used in China is imported from abroad, the price is expensive and there is a considerable dependence on the maintenance of the equipment. In addition, most of these devices use 51 series single-chip microcomputer or AVR single-chip microcomputer as the core processor. Due to the limitation of the hardware condition of the processor itself, the detection accuracy cannot be very high, and the system function expansion is difficult. Moreover, the current sealing performance testing equipment still has the following deficiencies: 1. The added value of the sealing performance testing equipment is not high, the technical content is low, and the independent innovation ability of the core technology of the industry and products is weak. ...
