Booster Pump Life Test Bench (24 stations)

1. Basic Requirements

1.1 It is suitable for start-stop and operation life tests of booster pumps of water purification equipment.

2. Device Capabilities

2.1 Meet QB/T 4144 “Reverse osmosis Water Purifiers for Household and Similar Purposes”, QB/T 4697-2014 “Reverse Osmosis for Household and Similar Purposes”.

The technical requirements specified in the standards such as infiltration water purifier and special pressurized pump for nanofiltration water purifier.

3. Test content

3.1 It is mainly used for start-stop and operation life tests of booster pumps of water purification equipment, and the number of switches and parameter settings can be set

And it can start and end according to the set number of cycles, and automatically and safely close.

Standard test: inlet water temperature (25±1) °C, inlet water pressure (0.2±0.02) MPa, test voltage (24±0.5) V/(36

±0.5)V DC.

Continuous operation performance: under the rated working conditions, the booster pump runs continuously, the booster pump has no jamming and water seepage, and the pump flow rate is tested.

The pressure is not less than 90% of the rating. Flow rate < 3.9L/min, continuous operation 2000h; 3.9 L/min≤ flow rate< 4.8L/min, continuous operation

line 1500h; The flow rate ≥ 4.8L/min, continuous operation for 1000h.

Intermittent operation performance: The pump starts 100,000 times with a cycle of running for 10s and stopping for 5s, and observes whether the booster pump is stuck and seeped

water phenomenon, test pump flow rate, pressure is not less than 90% of the rating.

Meet the standard test, and reserve the test variable can be adjusted.

5. Comprehensive performance of the equipment

5.1 Test environment: use constant pressure water supply system to ensure that the pressure before testing the booster pump is stable at 0.1MPa, and use high-precision pressure

The sensor feeds back the constant pressure water supply pressure, and uses the buffer water tank to stabilize the pressure fluctuations caused by the switching of multiple test pumps, on the equipment station

The power supply is provided by a DC 0-60V adjustable power supply;

5.2 Start-stop test: Before the test, adjust the pressure after the pump to the required according to the outlet flow rate manually adjusted by the pressure sensor behind the pump

After the pressure, click the test button, and the system will carry out the life test according to the set running time and stop time;

5.3 Continuous operation test: Before the test, adjust the pressure after the pump to

After the pressure is required, click the test button, and the system will carry out the life test according to the set running time;

5.4 Console: Using PLC control, the number of tests or running time is set on the computer, and the interface displays the cumulative number of tests

information such as running time and 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 equipment is equipped with a pure water outlet (manually switched with a ball valve for the tap waterway), and the pure water is supplied by the water supply laboratory, Party B

Responsible for the secondary distribution of pure water at the total pure water point of each laboratory; The pure water of this device belongs to the self-recycling when used in the water tank

If the temperature of the noodles is too high, the water can be changed automatically.

6. Other Requirements

6.1? The material of the equipment pipe is made of 304 stainless steel.
