How to solve the problem of frequent start of household booster pump?

Reasons for frequent start-up of booster pumps:

1.Faulty sensor of the automatic booster pump. Sensor failure can lead to inaccurate feedback pressure data, which can lead to an incorrect controller that automatically starts and the pressure rise stops.

If both of the above possibilities are ruled out, it is a sensor failure problem. Generally, you can contact the merchant to replace the sensor.

2.There is a water leak somewhere at the front end of the line where the auto booster pump is installed. It is normal for the booster pump to start automatically due to a drop in pressure caused by a water leak.

This is not difficult to solve, turn off the power supply of the booster pump, if there is no one to use water, observe whether the water meter is turning, if it is turning, it means that there is a leakage somewhere. If the pipe is leaking, the pipe can only be replaced.

3.The check valve of the automatic booster pump is not well sealed, and the pressure is not maintained, and the water that has been pressurized will flow back to the pipeline from the gap of the check valve, causing the pressure to drop to the lower starting limit, so the booster pump will start. When the booster pump is started to increase the pressure, it will stop to maintain the pressure, and the pressure will be maintained for a period of time because the seal will not return to reduce the pressure, and the booster pump will start again.

This reciprocating cycle causes the automatic booster pump to start and stop frequently when no one is using water.

The solution is: after the booster pump is pressurized, immediately disconnect the power supply of the automatic booster pump, observe whether the pointer is declining at a certain time from the table pointer, if it is and no one uses water, 100% judgment is that the check valve is not well sealed and leaking. The only solution is to replace the check valve.

4.It may be that the shutdown pressure value is set too high. If the shutdown pressure is set too high, the booster pump will not be able to reach the set pressure value regardless of whether there is water or not, and it is natural not to stop the machine.

Solution: If there is a pointer pressure gauge, first look at the indicated position of the pointer pressure when the current shutdown is not stopped, note down this pressure value, and then check what the corresponding set stop pressure value is (only for those who can set the start and stop pressure value by themselves), and then try to lower the set stop pressure value appropriately.

Booster pumps. Reasons for frequent startups:

1. Check valve leakage.

Booster pumps start frequently and have a long start-up time; There is a situation where the waste water does not stop flowing.

2. The filter screen is blocked.

Check whether the filter screen of the booster pump is blocked, which will affect the normal use of the booster pump. It is recommended to clean up in a timely manner.

3. The raw water pressure is low.

After detecting the pressure of the water source, the wastewater can be temporarily blocked, and the booster pump will adjust to the normal water production state.

The solution to the frequent start of the booster pump:

1. During installation, the front end of the booster pump pipeline leaks. A water leak can cause the booster pump pressure to drop. The solution is to turn off the power supply of the booster pump, if no one uses water, you can observe whether the pump is rotating, and the rotation indicates that there is a leak in some places.

2. Frequent start of the booster pump can turn off the pressure, and frequent start indicates that the outlet pipe is relatively thin, so that the water flow is relatively small, and the pressure is too large, and frequent start will occur. The solution is to simply adjust the pressure switch.

It can easily solve the problem of frequent start-up of the booster pump. When the booster pump is used, the water pipe is thick and the water flow is large, and the booster pump will always be in a pressurized state and will not stop.

Booster pumps. There are generally three reasons for frequent startups:

1. The raw water pressure is low.

Judgment method: detect the raw water pressure; After the wastewater is temporarily blocked, the machine will switch to the normal water production state; The time from pump start to stop is shorter.

2. PP cotton is blocked.

Judgment method: check whether the filter element has exceeded the service cycle; After the wastewater is temporarily blocked, the machine will switch to the normal water production state; Short pump start-to-stop time.

3. Check valve leakage.

Judging method: the pump has a long cycle of frequent start-up; At the same time, there is a phenomenon of non-stop flow of wastewater.

Uses of household booster pumps.

1. The water pressure of the water heater is insufficient, resulting in no ignition, and the installation of a household booster pump can easily solve this problem, so that you can take a hot bath with peace of mind.

2. The use of water storage tank, solar energy, or the roof pool of early buildings, under normal circumstances, the water drop is small, and the use of household booster pump can greatly increase the water pressure, and can maintain the stability of the water pressure.

3. Most apartments use independent water supply systems, equipped with water towers on the roof, and the water pressure is insufficient and the water volume is too small due to the proximity of the top-floor residences to the water towers, and the installation of household booster pumps can easily solve this problem.

4. The heating area of the heating system is large and the conveying distance is long, resulting in serious heat loss.

heat dissipation rate, thereby increasing the indoor temperature.

The booster pump always starts up without stopping during normal use, which may be caused by the following reasons:

Leaking water pump: If there is a leak in the booster pump, such as a poor seal or a leak in a pipe connection, which can cause the water pressure to drop, the booster pump will automatically start.

Pump setting too low: If the booster pump is set too low, for example, if the pressure value is too low, then the booster pump will still start even if the water pressure has been met.

Damaged pump pressure switch: If the pressure switch of the booster pump is damaged, then it will not be possible to detect that the water pressure has reached the required level, and the booster pump will continue to start.

Controller failure: If the booster pump is equipped with a controller, then a controller failure can also cause the booster pump to continue to start.

It is necessary to diagnose according to the specific situation, check whether the pump is leaking, check whether the setting value is reasonable, check whether the pressure switch is damaged, check whether the controller is working properly, etc. If you can't solve it on your own, it is advisable to seek professional help.

Guangzhou Haoxiong Pump Industry will answer for you:

Landlord, I will give you a detailed analysis and give corresponding solutions.

Cause: The reason why your pump starts frequently is because the automatic principle of this pump is based on the [differential pressure type] control, and when working, it works through the set upper and lower limit pressure values. To put it simply, if you are still using water after the shutdown, the pressure will drop to the lower pressure limit, and the pump will be restarted.

If you are in use, the pump frequently starts and stops, it may be because the upper and lower limits are too close, if: the factory value is set to stop the kilogram pressure, and the kilogram is to start, this state, if you are in use, turn on the faucet for a moment, the pressure will plummet to, at this time the pump will start, the pump will start as soon as it is fast, the pressure value of the pipe network will soon reach the kilogram, and the machine will stop immediately. And so on, so there is your frequent start and stop phenomenon.

The spring differential pressure control switch is already a phased product, he not only controls inaccurately, but also has a large noise when working, and can not accurately set the upper and lower limit pressure values.

Solution: Replace with a ** [differential pressure automatic booster pump] or [JWS-BL horizontal variable frequency booster pump]. ** Differential Pressure Automatic Booster Pump ** Differential Pressure Automatic Booster Pump is integrated with water flow control elements, which is still started when the lower pressure limit is reached, but he stops not only by stopping when the upper limit is reached, but also by judging whether there is water flow, if there is water flow, it will not be stopped.

This feature prevents you from having to reach the upper limit of the network pressure when you are using less water, but because you are using water, it will not stop and cause frequent starts and stops during the water use period, resulting in unstable water pressure. The inverter booster pump is even better, no matter how you use water, it will properly adjust its own speed according to your water consumption to achieve the purpose of constant pressure water supply.

Because the water pressure decreases with water, the booster pump starts, stops after the pressure is reached, and then the water pressure decreases, and so on, so it starts frequently. 、

Most of the booster pumps are high-rise households due to the water pressure supply is not available, the way is mainly the water tower, the water pressure itself is large from the top down, and the water pressure is greater if the booster pump is used, and the water pipe may break over time, so it is recommended to reduce the pressure of the pressure pump.

What is the reason why the household booster pump does not work Hello dear, the motor is damaged, even if the power is supplied through the control cabinet, the motor still cannot work normally. There may be something stuck in the pump, and the motor will trip if it does not function properly after powering on. The pressure of the sensor is broken, and the system cannot feel the pressure so it cannot start properly.

In the case of an air-pressure booster pump, it may be that the set value of the start is too low, for example, the set pressure is set, and the actual pressure cannot be started in the case of the actual pressure. If it is controlled by frequency conversion, it may be due to the failure of the constant pressure water supply device to start. Hope it helps.

Household booster pumps not working can be caused by the following reasons:

Power failure: The household booster pump needs to be plugged in to work, and if the power supply fails, the pump will not work. You can check whether the power switch, fuse, etc. are normal.

Water source problem: If there is no water at the inlet of the booster pump or the water level in the water source is too low, the booster pump will not work properly. It is possible to check if the water source is working properly and clean the filter.

Pump failure: A failure of the booster pump itself can also cause it to not work. You can check whether the pump motor is working properly, whether the rotor of the pump is stuck or whether the impeller is damaged, etc.

Controller failure: If the booster pump has a controller, the controller may also fail. You can check whether the power supply and circuitry of the controller are normal.

Piping problems: Plugging or broken tubing in a booster pump can also cause the pump to not work properly. You can check the cleanliness and condition of the pipeline. Suspicious of oak stains.

If none of the above problems exist, it is recommended to contact a professional maintenance personnel for inspection and repair.

1. The driving piston seal is worn, resulting in air collusion on the upper and lower sides of the piston;

2. If the reversing valve is not clean, it will not be able to move normally due to damage to the seal;

3. The connection of the two pistons is damaged, the cotter pin falls off, and the two piston rods are misaligned, resulting in the piston rod cannot move;

4. The seals of the booster cylinder are stupid and leakage.

No electricity, no water or a broken pump.
