Referring to fig. 1, the water pump can be disassembled into a pump body and a terminal box base, and a button for controlling the switch of the water pump is arranged on the terminal box base.
The test system comprises:
the device comprises pipeline equipment, a pressing test rod, a voltage sensor, a first pressure sensor and a processor;
the pipeline equipment is a part for providing working environment for normal work of the pump body of the water pump. Generally, in the pipeline equipment, liquid (generally water) circulation can be formed under the work of the pump body, and the pump body is prevented from being damaged due to the fact that the pump body does not have a working environment under the working state.
Generally, when testing the key, the following types are mainly included: a pneumatic key life tester, an electric key life tester, etc. The pneumatic key life tester utilizes a pneumatic component to drive a test pressure head to move up and down back and forth, so that a key is repeatedly hit; the electric key life tester uses a motor to drive an eccentric wheel to replace a test pressure head to move up and down and back and forth by a connecting rod, thereby repeatedly striking the key. In this embodiment, it is not limited to which type is specifically adopted to drive the pressing test rod. As long as the pressing test rod can be pressed with a certain force to press the key.
The voltage sensor is mainly used for sensing the measured voltage and converting the measured voltage into a sensor with a usable output signal. In various automatic detection and edition systems, it is often necessary to acquire and track the ac and dc voltage signals varying at high speed.
A pressure sensor is a device or apparatus that senses a pressure signal and converts the pressure signal into a usable output electrical signal according to a certain rule.

The press testing rod presses the keys of the junction box base. When the pressure sensor is pressed, the pressure generated by the contact of the pressing test rod and the key is taken as a pressure feedback signal to be received by the first pressure sensor. The first pressure sensor is arranged on the pressing test rod. The first pressure sensor is also in communication connection with the processor and transmits a numerical value corresponding to the pressure feedback signal to the processor for subsequent processing by the processor.
Generally, a pressure range interval can be set in the processor, and when the value corresponding to the pressure feedback signal is in the range interval, the mechanical condition of the key is determined to be normal. And when the numerical value corresponding to the pressure feedback signal is not in the range interval, determining that the mechanical condition of the key is abnormal.

The pump body and the junction box base are separated, but the water pump can normally run. In order to ensure the normal operation of the pump body, the pump body needs to be arranged in the pipeline equipment. The voltage sensor generates voltage signals according to the state of the keys, and the voltage signals output by the terminal box base are different when the keys of the terminal box base are not pressed and are pressed. After each press, the voltage signal fed back by the key of the terminal box base can be captured and recorded through an electric signal feedback line welded by a water pump driver, and the voltage signal is received by a voltage sensor and processed into a corresponding numerical value. The voltage sensor is in communication connection with the processor and transmits a numerical value corresponding to the voltage signal to the processor so as to be used for subsequent processing of the processor.
Generally, a voltage range interval can be set in the processor, and when the corresponding value of the voltage signal is in the range interval, the electrical condition of the key is determined to be normal. And when the numerical value corresponding to the voltage signal is not in the range interval, determining that the electrical condition of the key is abnormal.
Through the above embodiment, the testing system of the water pump key can collect the pressure feedback signal of the key and the voltage signal of the key, and transmit the corresponding numerical value of the signal to the processor, and the processor processes the received data and judges the mechanical condition and the electrical condition of the key.

Generally, the water tank is used for retaining water, and the pump body is used for pumping water from the water tank through the water inlet pipe, and the pump body pumps water and then discharges the water to the total water outlet pipe through the water outlet pipe. The total water outlet pipe can be connected with a water tank pipeline to realize internal circulation of water. A plurality of pipeline devices can be arranged, and the same total water outlet pipe is used, so that simultaneous testing of a plurality of keys can be realized.

And when the value corresponding to the voltage signal belongs to the first voltage range, determining that the electrical condition of the key is normal. And when the value corresponding to the voltage signal does not belong to the first voltage range, determining that the electrical condition of the key is abnormal.
And when the button is not pressed, the water pump stops working, and the liquid stops flowing. At this time, the voltage sensor sends a voltage signal to the processor. The processor stores a second voltage range, wherein the second voltage range is the voltage range when the button is not pressed and the water pump stops working. And when the value corresponding to the voltage signal belongs to a second voltage range, determining that the electrical condition of the key is normal.

A support table, preferably a disc with a diameter of 250mm, is provided on the support column. At the moment, the locking device is arranged on the supporting table board, and the junction box base is fixed on the supporting table board. In order to further reduce the impact of the pressure testing rod on the working table, a mat can be arranged below the junction box seat. The bedding is replaceable, the thickness is 10mm, the shape is not limited, and the bedding can be matched with the locking device conveniently.
And when the pressing test rod moves to the lowest part, the pressing test rod is contacted with the key to perform pressing operation. When the key is pressed by pressing the test rod, pressure is generated, and the pressure is captured by the first pressure sensor as a pressure feedback signal.
On the basis of the above embodiment, the pressing test rod includes a second pressure sensor, and the second pressure sensor is used for setting the pressure when the pressing test rod contacts with the key.
