Problems solved by technology
[0004] However, due to the frequent action of the high-voltage switch, its life performance index seriously affects the probability of failure of the pure water machine
When the high-voltage switch exceeds its service life and fails, it is easy to cause the whole machine to fail

The invention discloses a pressure switch service life test tooling comprising a fluid supply device (1), a pressure adjusting valve (2) connected to the fluid output end of the fluid supply device (1), a pressure switch installation position (5) and a discharge pipeline communicated with the outlet of the pressure switch installation position (5). The inlet of the pressure switch installation position (5) is connected to one end of the fluid supply device (1) far from the pressure adjusting valve (2) through an incoming pipeline. According to the tooling, a pressure switch to be tested is installed in the pressure switch installation position, the actual operation state of the pressure switch during machine operation is simulated, and the service life testing operation of the pressure switch is completed; by means of the pressure switch service life test, the service life quality of the pressure switch can be controlled in the factory testing process, and the fault rate of an entire machine caused by pressure switch failure is decreased.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a pressure switch life detection tool. Background technique [0002] The pressure switch is a pressure control device. When the measured pressure reaches the rated value, the pressure switch sends out an alarm or control signal. [0003] Taking the high-voltage switch in the pure water machine as an example, the high-voltage switch installed in the pure water machine is used to automatically control the work of the pure water machine. When the water pressure of pure water reaches a higher pressure (such as 0.3Mpa), the high-pressure switch sends out a control signal, cuts off the power supply, and makes the pure water machine stop; When the pressure is reduced to a lower pressure (such as 0.15Mpa), the high-pressure switch sends out a control signal, and the power is turned on, so that the pure water machine enters the normal water production state. By setting the h...
