Solenoid valve life test bench

Solenoid Valve Life Test Bench (12 stations)

1. Basic requirements: suitable for durability testing of solenoid valves at room temperature/hot water inlet and outlet of water purification equipment;
2. Equipment function: meet the technical requirements specified in the standards such as “QB/T 4144 Reverse osmosis Water Purifier for Household and Similar Purposes”.

Beg;

3. Test content: It is mainly used for the durability test of water inlet solenoid valve and waste water solenoid valve of water purification equipment.

Standard test: test water temperature (20±5) °C, hot water (95±5) °C. Connect the solenoid valve to the test set, use the gauge

The digital electronic control board controls the on/off of the solenoid valve by controlling the tap water on/off through the solenoid valve, and records the number of switches and switches for 100,000 times

Close test to monitor whether the solenoid valve is working properly throughout its life. Meet the standard test, and reserve the test variable can be adjusted.

4. Technical Parameters

4.1 stations: 12 stations (4 of which can be used for wastewater valve testing, similar products can be tested together, different categories.)

No), the same pressure source, using a ball valve input;

5. Comprehensive performance of the equipment

5.1 Water inlet solenoid valve test: use constant pressure water supply system to ensure that the pressure before testing the booster pump is stable at the set pressure, and use high precision

The degree pressure sensor feeds back the constant pressure water supply pressure, and uses the buffer water tank to stabilize the pressure fluctuations caused by the opening and closing of multiple solenoid valves, in accordance with

The set on-on and disconnection time are used for life testing, and the test valve is judged to be open according to the feedback of the flowmeter after the valve is opened.

5.2 Wastewater solenoid valve test: use constant pressure water supply system to ensure that the pressure before testing the booster pump is stable at the set pressure, and use high precision

The degree pressure sensor feeds back the constant pressure water supply pressure, and uses the buffer water tank to stabilize the pressure fluctuations caused by the opening and closing of multiple solenoid valves, in accordance with

The set on-on time and disconnection time are used for life test, and after the valve is opened, judge whether the test valve is flushed according to the feedback of the flowmeter.

After closing the valve, judge whether the test valve is in a water production state according to the feedback of the flowmeter.

5.3 During the product test, if the test fault tolerance is reached, the test will be automatically stopped, and the prompt light will be on to remind the operator to proceed

Dispose.

5.4 Console: Using PLC control, the number of tests, opening time and closing time are set on the computer, and the interface displays the cumulative tests

times, and the current running status.

5.5 Safety protection: The water tank has the functions of overflow, leakage and low water level protection, etc.

5.6 The water used by this equipment is self-recycling. When the water temperature in the water tank is too high, the water can be changed automatically.

5.7 Equipped with water temperature heating device, suitable for durability test of hot water solenoid valve.

6. Other requirements: The equipment pipe material is made of 304 stainless steel.
