The system comprises an industrial control computer, a data acquisition system, a control system and a water supply system, wherein the water supply system comprises a plunger pump driven by a motor, a first water rank, a filter, an adjusting valve and a second pressure gauge, a pipeline between the second pressure gauge and a first solenoid valve is connected in a by-pass mode with a pressure release path sequentially connected with a second solenoid valve and a second water tank, the data acquisition system comprises a data acquisition module connected with the industrial control computer, and a strain gauge and a pressure sensor connected with the data acquisition module, and a strain gauge, and the control system comprises a control module connected with the industrial control computer, and a frequency converter, the first solenoid valve and the second solenoid valve in circuit connection with the control module. The system is advantaged in that the structure is simple, the system is convenient to use, the system can be widely applied to measurement on stress, strain and pressure under high voltage or super high voltage states, and the automatic system can guarantee safety of an operator.

Description

technical field [0001] The invention belongs to the detection field, in particular to a controllable pressure, stress and strain testing system of a herringbone corrugated plate and shell heat exchanger. Background technique [0002] As an important equipment for industrial heat transfer, heat exchangers are indispensable for industrial development. Heat exchangers are generally used in harsh environments with high temperature and high pressure, so they are required to meet various special situations and harsh conditions. Security testing is especially important. [0003] According to relevant experience, the traditional test system needs to manually adjust the pressure, increase the pressure, and release the pressure. Exposure to a high-pressure environment increases the danger of personnel, and it is difficult to operate slowly. The test system disclosed in the present invention is a full-automatic test system, which is simple in operation, low in cost and intelligent, an...
