What is the reason for the rhythmic squeak of the progressive cavity pump 5

Hello! Screw pumps.

If there is an abnormal sound, first of all, we need to carefully find the cause of the abnormal noise, and then eliminate it one-on-one, and determine the solution after finding the cause.

Possible causes of abnormal noise in progressive cavity pumps:

1.Whether or not foreign matter with hard particles has entered the pump.

2.There is wear and tear on the internal parts of the pump, which causes the gap of the parts to change.

3.The inlet of the pump is not where there is an air leak.

We can look for the specific reasons around the above aspects:

1.The oil temperature of the screw pump is 60 degrees, which is not too high, but the bearing damage will not affect the use under normal circumstances, even if the small ball of the bearing is damaged, it will not be affected, and it can run normally, but if it is a long time, the oil temperature will rise, and the sound will become louder and louder, and the motor may be burned in serious cases.

2.The long-term friction of the wearing parts of the pump causes the concentricity of the pump and the motor.

If there is a deviation, it can be corrected.

3.The selection and operation of the screw pump, the power of the pump is too large or too small when the pump is selected, which causes the pump to have abnormal phenomena, and the other is not in accordance with the operating procedures.

Operation, so that the pump idling, holding the pump, or the air in the pump is not completely removed, these will also cause the pump to produce abnormal noise.

4.The progressive cavity pump does not carry out the necessary maintenance and maintenance, and the pump pipe or filter device should be cleaned regularly.

According to the above methods, it is believed that the problem of abnormal noise of progressive cavity pump can be completely solved.

Rhythmic squeak and rattle in progressive cavity pumps can be caused by a variety of reasons. Here are some possible reasons:

Bearing wear or damage: Bearing damage may cause abnormal noise during operation of the progressive cavity pump. Inspect the bearings and replace them if necessary.

Worn or damaged screws: Wear or damage to the screws may cause abnormal noise during pump operation. Inspect the screw and replace it if necessary.

Worn or damaged couplings: Wear or damage to couplings may cause abnormal noise during pump operation. Inspect the coupling and replace it if necessary.

Loose inside the pump: Loose parts inside the pump may cause abnormal noise during pump operation. Inspect the internal parts of the pump and tighten loose parts.

Unstable connection between pump and motor: An unstable connection between pump and motor may lead to abnormal noise during pump operation. Check the connection between the pump and the motor and make sure the connection is stable.

Unstable Pump Installation: Unstable installation of the pump may cause abnormal noise during pump operation. Check the installation of the pump and make adjustments if necessary.

To solve these problems, it is necessary to first determine the possible causes according to the specific fault phenomenon, and then carry out targeted inspection and maintenance. Regular maintenance of the progressive cavity pump to ensure that it is operating under the correct working conditions can effectively reduce the possibility of failure. If the problem cannot be resolved, it is recommended to contact a service professional or pump manufacturer for support.

The rhythmic squeak of the progressive cavity pump can be caused by:

1.The internal parts of the progressive cavity pump are damaged or worn, resulting in abnormal noise during the operation of the progressive cavity pump.

2.There is blockage or resistance in the inlet or outlet pipeline of the progressive cavity pump, resulting in abnormal noise when the progressive cavity pump is running.

3.The bearings of the progressive cavity pump are damaged or worn, resulting in abnormal noise during the operation of the progressive cavity pump.

4.There is a fault or imbalance in the motor or drive of the progressive cavity pump, which causes the screw pump to make abnormal noises when it operates.

5.The seals of the progressive cavity pump are damaged or worn, resulting in abnormal noise during the operation of the progressive cavity pump.

It needs to be inspected and repaired on a case-by-case basis.

It is estimated that there is a gap when inserted into the propeller shaft.

The progressive cavity pump has a rhythmic squeak sound, do you see that there is a gap in the propeller shaft?

The motor is overloaded, stalled at start, and that's it.

1. Screw pump, such as a single screw pump, the stator and the rotor are interference fit, that is, the rubber stator is tightly hugged by the rotor, so the starting torque is large.

2. If the rubber stator is swollen, or the medium contains more solid particles, especially irregular particles, it is easier to get stuck.

There are several reasons why the progressive cavity pump starts up and doesn't let the sleepy old turn:

Motor problem: Check if the motor is working properly, motor failure may cause the pump to not drive the screw normally. Confirm that the power cord is connected correctly and that the wiring inside the motor junction box is tight.

Insufficient starting torque: The starting torque of the motor may not be sufficient to drive the progressive cavity pump. In this case, it is necessary to check whether the motor specifications match the requirements of the pump.

Bearing Problems: Damaged or worn bearings may cause the screw to not function properly. Inspect the bearings and replace them if damaged.

Screw seizure: The screw may be stuck due to debris, rust, or wear. Check if the screw is stuck, and if so, remove the debris or replace the damaged one.

Coupling Issues: Check that the coupling is properly installed and adjusted, and that there is no damage. Coupling issues can cause the power transfer between the pump and the motor to flow poorly, causing the pump to fail to start.

Overload protection tripping: The motor may not be able to start lifting due to overload protection tripping. Check the motor's overload protection equipment, and if there is a problem, reset the protection equipment or contact a professional maintenance personnel.

To solve this problem, first check according to the above possible causes, and then make targeted repairs or adjustments. When performing repairs, make sure to follow safety protocols and use appropriate tools. If the problem persists, it is recommended to contact the pump manufacturer or a repair professional for support.

1. The motor rotor shaft of the fan is stuck due to lack of oil;

2. The front and rear ends of the motor of the fan are deviated, causing the rotor shaft to be stuck;

3. The starting capacitor is broken (or the capacity is reduced), causing no current (or too small current) in the coil of the starting winding

The sound of the screw machine air pump pump head clattering 1It is due to the presence of impurities in the cylinder block or cylinder, when the air pump rotates to the maximum position, the impurities will hit the cylinder block or cylinder inner wall, resulting in a clattering impact sound. 2.

In addition, the blades of the screw engine air pump may also rub against the surface of the cylinder, and the empty wheel will also produce a clattering sound. Solution:1

You can try changing the lubricating oil or installing a vibration preventer at the gas outlet to reduce the noise of the impact. 2.In addition, you can also change the rubber ring of the pump head to make it quieter.

At the same time, you can also install sound insulation materials on the housing of the screw machine to reduce the noise of the machine.

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is an abnormal sound in the door.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slideway grease can be used, while special door attachment grease is used for lubrication of window regulators, door lock mechanisms, and puller system inside the door.

In terms of brand selection, try to choose the commonly used brands in 4S stores, such as Kruber, Tiger Head Hotolube, Fusi Xiantan, etc. It is not advisable to use engine oil or ordinary butter, as it will freeze and shiver in winter, and the harmful smell will affect your health.
