Faults and Solutions of Electric Pressure Test Pump

The function of the electric pressure test pump is to pump water into the sealed cavity to check the tightness of the sealed cavity and the level of pressure. Electric pressure test pump is also commonly used to test the pressure of the water pump to check whether there is any leakage in the water pump. The electric pressure test pump is used many times and has great working intensity, so there are many failures. The failure phenomena of the electric pressure test pump factory are as follows: 1. Sometimes the pressure cannot be pressed up; 1. The pressure cannot be maintained or the pressure falls down soon after it goes up. So what is the cause of this phenomenon? Changjia pump industry to give you a summary:

1. the pressure of the electric pressure test pump does not work.

Processing method:

Exhaust the air, unscrew the bleed screw on the water pipe, pay attention to the high pressure at the motor end, first put the suction pipe at the low pressure end outside, let the high pressure absorb water first, and then put the low pressure suction pipe in the water tank.

The water inlet valve is blocked. There are 4 water inlet valves of the electric pressure test pump. Check the water inlet valve one by one, unscrew the nut on the water valve, and observe the water outlet size on the water valve. If it is large, the valve is normal. If the water output is small, the valve is abnormal and there are sundries blocking, which should be removed immediately.

2. the electric pressure test pump can suppress the pressure, it cannot keep the pressure.

Treatment method: check the pressure regulating valve on the right side of the water collecting block assembly, because it cannot seal the water, so it cannot maintain the pressure and replace it.

After the 3. is energized, the pressure of the electric pressure test pump cannot be activated all the time.

Cause: The rubber ring used for sealing is aging and needs to be replaced, or the load is very large, and the motor cannot move.

Study the causes of DSB electric pressure test pump failure:

1, just bought electric pressure test pump, but can't play up the pressure

Treatment method: exhaust the gas, press the switch to exhaust 5~6 times, pay attention to the switch do not close.

2. After the pressure test pump is running, the pressure cannot be kept

Treatment method: check whether the water quality is not clean, impurities stuck in the high-pressure valve to make it not dead, can be cleaned with diesel or kerosene.

3. The pressure of the electric pressure test pump cannot be hit

Treatment method: after the electric pressure test pump is used for a period of time, it is necessary to stop cleaning and use diesel or kerosene. There are 6 valves, 3 high-pressure valves and 3 low-pressure valves, which are gently knocked with a small iron rod to vibrate impurities.

4, the pressure can play up, but soon fell off.

Treatment method: The copper pipe joint inside should be broken. It is recommended to check and replace the pipe joint with a new one.
