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.

Temperature rise: Continuous operation for 2.5h under rated conditions, the temperature detector tests the surface temperature at 3 points at the head, middle and tail of the pump body

degree, take the difference between the maximum temperature and the ambient temperature to meet the requirements (flow rate< 2.6L/min, temperature rise≤35K; Traffic ≥

2.6L/min,温升≤50K)。

Rated current, rated flow and output pressure, plugging pressure, maximum current;

4.11 Adjustable power supply is configured to ensure the current capacity of 5A per station, and the DC is adjustable from 0-60V.

5. Comprehensive performance of the equipment

5.1 Running temperature rise detection: first fix the three temperature probes at the front, middle and tail ends of the pressurized pump, and then click to measure

Try, the system records the initial operating temperature in advance, and runs according to the running time set by the operator, and records it after the operation is completed

The temperature of the pressurized pump is recorded, and the maximum value is compared with the ambient temperature sensor to obtain the result.

5.2 Rated current, rated flow and outlet pressure test: connect the voltmeter and ammeter at the power supply of the pressurized pump, and wait for testing

The water inlet of the pressurized pump is equipped with a pressure sensor, and the water outlet is equipped with a pressure sensor and a flow meter, and the operator adjusts the power supply to

The rated power supply range of the pressurized pump, click to test, the system automatically adjusts the inlet water pressure, and then starts the tested pressurized pump, to be passed

After the set settling time, the system displays the current instantaneous flow, operating current, operating voltage and outlet pressure.

5.3 Maximum current and plugging pressure test: According to the operation mode of 5.2, the water outlet is closed after the operation of the pressure pump to be tested is stable

The valve then records the current operating current and output pressure, and the outlet uses a dual protection mechanism of hardware and software to block the pressure

When the force is too high, the pressure is automatically relieved to ensure the personal safety of the operator.

5.4 Self-priming function: Use the water channel valve to automatically switch the inlet line of the pressure pump to be tested to have a vertical height of 2m (distance from the water surface

off the pipeline connected with a hose), start the pump to be tested and judge whether the pump to be tested can reach the specified flow within the specified time

volume range.

5.5 Test environment: Use constant pressure water supply system to ensure that the pressure before testing the booster pump is stable at 0.2MPa, 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 an adjustable power supply.

5.6 Console: Using PLC control, select the test items on the industrial computer and input the corresponding test parameters, and the interface displays the test

Information such as test information and current operating status.

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

5.8 The equipment is equipped with a pure water outlet (manually switched with a ball valve from the tap waterway), and the pure water is supplied by the water supply laboratory and 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 °C of the pure water is too high, the water can be changed automatically.

6. Other Requirements
