What is the cause of the noise of the water pump

1. It is usually caused by mechanical noise, when the machinery in the pump room will produce noise when it is running, therefore, it will cause the pump to also make noise.

Sound. Moreover, the rigidity of the pump is not good, and the impeller inside is easy to fall off, so when it is running, it will cause a large noise in the pump.

2. In addition to mechanical noise, there is also a reason for the pump itself, its base design is unreasonable, or the base is filled with concrete, and there is a hollow drum problem. Therefore, when the water pump is working, it will vibrate and produce noise.

3. There may also be aerodynamic noise, the fan inside the pump is rotating with the air, so there will be some noise in the blades of the fan. Therefore, when this situation occurs, it is necessary to do a good job of windshield treatment at any time to avoid too much wind in the air and drive the pump to produce noise.

4. When the hydraulic force vibrates, it will also be inducedThere is noise in the water pump, so when using the water pump, the internal hydraulic power should be controlled as much as possible to prevent the noise of the water pump and affect the living of users downstairs.

Processor:

1. Install the water pump or reduce the installation height of the water pump

2. Replace the ball bearing of the motor;

3. Correct the bent water pump spindle or adjust the relative position of the water pump and the motor.

Other faults and solutions:

The water pump will not start.

1. Relax the filler and dredge the drainage tankDisassemble the pump body to remove debris and rust;

2. Remove the pump shaft to correct or replace the new pump shaft.

Extended Materials. The noise of the water pump may be in the following aspects:

1) The impact of the rotary vane on the cylinder block, the residual volume of the water pump and the sound of the pressure oil in the exhaust dead gap;

2) The impact of the exhaust valve plate on the valve seat and supporting parts;

3) Echoes and bubble bursts in the box;

4) Bearing noise;

5) Noise caused by a large amount of gas and oil impacting the oil baffle;

6) Miscellaneous. Such as the noise caused by transmission, the fan noise of the air-cooled water pump, etc.

7) Motor noise, which is a crucial internal factor.

When users choose water pumps, it is best to go to the sales point approved by the agricultural machinery department, and be sure to recognize the manufacturer. It is recommended to give priority to the purchase of water-filled submersible electric pumps, and to see the brand and product quality certificate. Don't buy "three nos".

That is, there is no manufacturer, no production date, and no production license.

You can tear it down and repair it, and if you open it again, there will be problems soon.

1. Use the sound insulation cover of the water pump A sound insulation cover can be installed on the water pump, which can isolate the sound from the water pump and avoid the sound from coming out.

2. Vibration reduction of the water pump A vibration reduction device can be installed under the water pump to reduce the vibration of the water pump, and elastic support can be done in the pipeline and inlet and outlet pipelines of the water pump to reduce noise transmission.

3. Install an exhaust fan You can install an exhaust fan in the computer room, and the exhaust fan should be equipped with a muffler, which can reduce noise.

Noisy water pumps are usually caused by:

The installation of the water pump is unstable, which causes resonance and noise. At this time, the pump should be reinstalled and the pump installed smoothly and firmly.

The pump inlet pipe is too short or too small, resulting in cavitation noise. At this time, the length or diameter of the inlet pipe should be increased to reduce the noise generated by cavitators.

The impeller of the water pump is damaged or deformed, resulting in an uneven flow of water and noise. At this point, it should be late to replace the impeller or carry out repairs.

The water pump bearings are worn or too tight, causing friction to produce noise. At this point, the bearing should be replaced or adjusted.

The pump motor is faulty or overloaded, resulting in excessive noise. At this time, the motor should be inspected and repaired or replaced in time.

In order to reduce pump noise, the following measures can also be taken:

Install materials such as soundproof walls or soundproof cotton around the pump to reduce noise transmission.

Install shock absorbers and cushions to reduce noise generated by vibration.

Regularly maintain the water pump and check whether the impeller, bearings and other parts are normal.

Use a low-noise motor and keep the motor in working order.

The reasons for the high noise of the water pump may be due to the following aspects:

1.Problems with the design and manufacture of the pump itself. The pressure, flow, speed and other parameters of some pumps are unreasonable, resulting in large vibration and loud noise of the pumps.

2.The water pump is installed in a silver position and in a way that is unreasonable. The water pump is easy to produce vibration and noise when it is installed on the ground or when the foundation is not firm, and attention should be paid to selecting the appropriate position and method when installing.

3.The operating state of the water pump is unstable. The unstable situation of the pump during operation, such as uneven flow and unstable pressure, can easily lead to the increase of pump vibration and noise.

4.Pipes and valves are not properly designed. Improper design of the pipes and valves of the water pump, such as too long pipes, too many bends, unreasonable valve openings, etc., will affect the working efficiency of the water pump and increase vibration and noise.

5.The maintenance of the water pump is not in place. The long-term use of the water pump is prone to wear and aging, such as bearing wear, seal aging, etc., which will lead to the unstable operation of the pump and the increase of noise.

In response to these problems, the following measures can be taken to reduce pump noise:

1.Optimize the pump design and manufacturing process to ensure that the parameters of the pump are reasonable.

2.Install the water pump reasonably, and take vibration reduction measures, such as installing vibration reduction pads, vibration reduction brackets, etc.

3.Strengthen the maintenance of water pumps, regularly inspect and replace bearings, seals and other wearing parts.

4.Optimize the design of pipes and valves, reduce the resistance and pressure fluctuations of the pump, and reduce the vibration and noise of the pump.

5.Reasonable control measures, such as reducing the running time of the pump, reducing the operating speed, etc., to limit the generation and spread of noise.

The treatment method of the noisy water pump is as follows:

1.Check whether the pump is installed correctly: The incorrect installation of the pump is one of the main causes of high noise, and it is necessary to check whether the pump is fixed and stable and in the correct position.

2.Adjust the running speed of the pump: Modern pumps generally support the adjustment of the operating speed, and the noise of the pump can be reduced by adjusting the operating speed. You can check the pump manual, or consult the relevant manufacturer.

3.Installation of soundproofing materials: Soundproofing materials such as foam panels can be installed around the pump to reduce noise generation and transmission.

4.Replace the pump: If the pump is too old and the noise is difficult to eliminate, then the ultimate solution is to replace the pump. It is recommended to choose a high-quality, low-noise, low-energy pump to reduce noise and maintenance costs.

In general, the method of eliminating the noise of the pump needs to be selected according to the actual situation, and some methods can be used at the same time to achieve a better noise reduction effect.

1) Choose a pump with low speed, low noise, and low energy, which not only reduces noise, but also reduces the chance of pump problems.

2) It is necessary to dampen the shock of the pump unit and install a vibration isolator or elastic gasket material under the base.

3) The depth of the water intake of this large stove should not be too high or too low, and the connection with the suction pipe needs to be sealed, for these details if not treated, it is easy to cause the water flow into the air to cause cavitation noise.

4) The connection between the suction pipe and the outlet pipe needs to use a soft connection device.

5) However, the installation design of the water pump after slag destruction needs to be reasonable, and it needs to meet the allowable cavitation allowance standard of the water pump.

For other pump noise problems and solutions.

1) For the pump with imperfect foundation, it needs to be re-installed according to the foundation requirements.

2) For the noise caused by the imbalance of the impeller rotating body, it is necessary to check the rotation balance of the impeller, and replace the impeller if necessary.

3) If there is dirt and air mixed in the pump, it is necessary to remove the dirt in the pump and then seal it, so that the pump does not accumulate empty fiber imitation quietly.

Vibration reduction measures for water pumps.

1) Choose a pump with low speed, low noise and low energy;

2) For the vibration reduction of the pump unit, the vibration isolator or elastic liner material is installed at the base of the pump;

3) The connection between the suction port and the water pipe is sealed with a sail grip;

4) The connection between the suction pipe and the outlet pipe uses a soft connection state stove celebration device;

5) The installation design of the water pump should meet the allowable cavitation allowance standard of the water pump.

For other pump noise problems, such as the noise caused by the imbalance of the impeller rotating body, the impeller can be replaced if necessary, if there is dirt and air mixed in the pump, the dirt in the pump needs to be removed and then sealed.

There may be the following reasons for the high noise of the water pump:

The mechanical structure of the pump itself, such as bearing wear, impeller imbalance, pump casing deformation, etc., will cause vibration and noise in the pump.

The inlet or outlet pipe of the water pump is not properly secured, causing the pipe to vibrate and also cause noise.

Improper installation of the pump, such as the resonance area, the position of the wall vibration, etc., will also affect the noise of the pump.

Loose or deformed couplings such as couplings and reducers between the pump and the motor will cause vibration and noise.

Environmental problems in the use of water pumps, such as the medium used in the pump is too high, the viscosity is too large, or the use environment of the pump is noisy, etc., may lead to the noise of the pump.

In order to solve the problem of high noise of the pump, it is necessary to comprehensively consider the above factors, check and adjust the mechanical structure, pipeline connection, installation position, connectors, etc. of the pump, and pay attention to the use environment and operation status of the pump.

Noise from cavitation.

Noise from loose rotor components.

The noise caused by the low flow rate of the pump.

The noise caused by the hail obstacle of the rolling bearing: the installation is too tight, the oil volume in the bearing is insufficient, the bearing runs the ring, and the bearing is damaged.

1. The impact of the rotary vane on the cylinder block The residual volume of the water pump and the pressure in the exhaust dead gap are the sound of the oil.

2. The impact of the exhaust hail valve plate on the valve seat and supporting parts.

3) Echoes and bubble bursts in the box;

4) Bearing noise; Swift no.

5) Noise caused by a large amount of gas and oil impacting the oil baffle;

6. Others, such as the noise caused by transmission, the fan noise of the air-cooled water pump, etc.

7. Motor noise This is a crucial factor

Water pump noise reduction treatment scheme.

1.Shock absorber.

The shock absorber is installed at the base of the pump to reduce the transmission rate of the pump vibration, and at the same time cut off the connection between the pump and the surrounding solids to reduce the impact of vibration on the surroundings. The second is the vibration of the pipeline, replace the elastic support frame, and fill the shock-absorbing and sound-absorbing material at the entrance and exit walls of the pipeline to reduce the vibration generated by the pipeline. As well as the use of soundproof felt sound-absorbing cotton and other materials for soundproof wrapping of the pipeline, it can reduce vibration and solve the impact noise in the pipeline.

2.Soundproofing of the machine room.

The sound insulation treatment of the pump room is to improve the sound insulation capacity of the pump room wall by using sound-absorbing and sound-insulating materials on the wall of the pump room and laying sound-absorbing cotton, soundproof felt and other materials on the top. At the same time, replace the soundproof doors and windows according to the sound insulation requirements to avoid noise leakage, and finally install a muffler at the vent to avoid the noise of the water pump from coming out through the vent.

Reinstall, the installation points are as follows:

1. The radial runout of the rotating shaft of the equipment should be mm, and the axial channeling momentum is not allowed to be greater than mm;

2. The sealing part of the equipment should be kept clean during installation, the sealing parts should be cleaned, and the sealing end face should be intact to prevent impurities and dust from being brought into the sealing part;

3. It is strictly forbidden to hit and knock during the installation process, so as not to break the friction of the mechanical seal and the seal fails;

4. During installation, a layer of clean mechanical oil should be coated on the surface in contact with the seal so that it can be installed smoothly;

5. When installing the static ring gland, the tightening screw must be evenly stressed to ensure the perpendicular requirements of the end face of the static ring and the axis line;

6. After installation, push the moving ring by hand, which can make the moving ring move flexibly on the shaft and have a certain elasticity;

7. After installation, use the hand to move the shaft, and the shaft should not feel light and heavy;

8. The equipment must be filled with medium before operation to prevent dry friction and seal failure;

The fish tank has a buzzing resonance sound, which is very annoying, and fish farming is meant to be fun, because if the noise adds to the annoyance, it is really worth the loss.

The fish tank resonates, and the root is the water pump. Around the pump, we can find the cause and rectify it from the following three aspects.

One is the reason for the pump itself. After the pump has been used for a long time, it will inevitably age, or there will be some debris wrapped on the shaft, which will cause the shaft speed to slow down, and the pump may make a buzzing sound by itself. The pump can be lifted out of the water, and if you can hear a noticeable humming sound, you can determine that it is the pump problem.

In this case, you can replace the pump with a new one, or disassemble the pump and clean it yourself.

The second is the resonance between the pump and the pipeline. Especially when the pipe is a hard material, the vibration of the pump itself will be conducted to the pipe, and the pipe actually plays a role in amplifying the sound. In this case, the place where the pump is connected to the pipe can be replaced with a hose.

The third is the resonance of the cylinder block. Resonance often occurs when the fish tank is capped above or there is a hollow cabinet under the tank. But the source of the sound is the water pump.

Take a closer look, find the parts where the pump is in contact with the cylinder, and pad these parts with a sponge, which can basically be solved. Or adjust the direction of the fish tank and change the position, which may also solve the problem. The general rule is not to allow the hard water pump to come into direct contact with the hard cylinder block.
