The self priming pump rings every once in a while, and it s similar to the sound of water feeding.

The self-priming pump rings every once in a while, and it's similar to the sound of water feeding.

It shouldn't be a big problem, you check the fan cover, maybe one of the screws of the fan cover is loose, just tighten it with a wrench, or the fan is loose, and fix it with glue.

The cause of the failure of the self-priming pump is that there is water in the pipeline, and the water flows backwards.

Scope of application: 1. After installing a rocker arm sprinkler and flushing water into the air, it can be dispersed into fine raindrops for spraying, which is a good tool for farms, nurseries, orchards and vegetable gardens.

2. It is suitable for clear water, seawater and chemical medium liquids with acid and alkalinity and slurry with general paste (medium viscosity < 100 centipober, solid content can reach less than 30%).

3. It can be used with any type and specification of filter press, and is the most ideal pump for filter press when the slurry is sent to the filter press.

Main Applications:

1. Equipped with a rocker arm sprinkler, it can flush the water into the air and scatter it into fine raindrops for spraying, which is a good tool for farms, nurseries, orchards and tea gardens.

2. It is suitable for clear water, seawater and chemical medium liquids with acid and alkalinity and slurry with general paste (medium viscosity < 100 centipober, solid content can reach less than 30%).

3. It can be used with any type and specification of filter press, and the slurry is the most ideal supporting pump for filter pressing.

ZW self-priming non-clogging sewage pump is a new type of pump integrating self-priming and sewage discharge according to the structure and performance of ZX self-priming centrifugal pump and QW submersible sewage pump, and drawing on the advantages of similar foreign products.

The self-priming pump will continue to sound after not using water, and the frequency is not very fast because the water pressure cannot be maintained due to the problem of the return water seal.

The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a foot valve in the pipeline, and only need to ensure that the pump body is stored with quantitative fluid extraction before working. Self-priming pumps of different materials can be used for different liquids.

Self-priming pumps work by filling the casing with water (or containing water in the casing) before the pump starts. After starting, the high-speed rotation of the impeller makes the water in the impeller channel flow to the vortex shell, and then the inlet forms a vacuum, so that the water inlet backstop door is opened, and the air in the suction pipe enters the pump, and reaches the outer edge through the impeller channel.

The pumps all adopt the pump body structure of axial liquid return. The pump body is composed of suction chamber, liquid storage chamber, scroll chamber, liquid return hole, gas-liquid separation chamber, etc., after the pump starts normally, the impeller will inhale the liquid stored in the suction chamber and the air in the suction pipeline together, and be completely mixed in the impeller, under the action of centrifugal force, the liquid entrained gas flows to the outer edge of the scroll chamber, and forms a white foam belt with a certain thickness and a high-speed rotating liquid ring on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through a diffusion tube.

At this point, due to the sudden decrease in the flow rate, the lighter gas is separated from the gas mixture, and the gas continues to rise and be discharged through the pump body spout. The degassed liquid returns to the reservoir and enters the impeller again through the reflux hole, mixes with the gas sucked in from the suction line inside the impeller, and flows to the outer edge of the impeller under the action of the high-speed rotating impeller. As the process progresses over and over again, the air in the suction line decreases until the gas is exhausted and the self-priming process is completed, and the pump is put into normal operation.

Some pumps also have a cooling chamber at the bottom of the bearing body. When the bearing temperature rises more than 70 degrees due to heating, the coolant can be injected into the cooling chamber through any coolant pipe joint to circulate cooling. The sealing mechanism inside the pump to prevent the leakage of liquid from the high-pressure area to the low-pressure area is the front and rear sealing rings, the front sealing rings are installed on the pump body, and the rear sealing rings are installed on the bearing body, when the pump is worn to a certain extent after long-term operation, and affects the efficiency and self-priming performance of the pump, it should be replaced.

Summary. 7.Incorrect installation of outlet pipes, too many elbows: There are too many pipes in an N-shaped shape, and it is recommended to install an automatic exhaust valve at the highest point.

8.Three-phase motors are reversed: two phases are swapped.

9.The return hole of the self-priming pump is blocked, so that the steam and water cannot be separated: check and clean it.

10.Suction pipeline leakage: Eliminate the phenomenon of pipeline air leakage, check the method within the allowable suction range, the pump starts for 4-5 minutes, and the water has not been sucked up, please use your ears close to the inlet pipeline to listen to the sound of inhalation, or coat white latex in the suspected air leakage and other methods to repair.

The self-priming pump rings every once in a while, and it's similar to the sound of water feeding.

1.Voltage mask is too low: Adjust voltage 2

Suction lift is too high or the suction line is too long: reduce the suction lift or shorten the line3Excessive leakage of mechanical seals:

Repair or replace4The filter screen of the pump body or the inlet pipeline is blocked by debris stones: check and clean up the blockage and close the tie-up 5

The self-priming pump pump body is not filled with liquid storage or the liquid storage is insufficient: add enough 6Damaged or worn impellers

Replace the impeller with a new one.

7.The outlet pipeline is installed incorrectly, and there are too many elbows: there are too many pipes that are broken into an N-shape, and it is recommended to install an automatic exhaust valve at the highest point.

8.Three-phase motors are reversed: two phases are swapped.

9.The return hole of the self-priming pump is blocked, so that the steam and water cannot be separated: check and clean it.

10.Suction pipeline leakage: Eliminate the phenomenon of pipeline air leakage, check the method within the allowable suction range, the pump starts for 4-5 minutes, and the water hole pants have not been sucked up, please use your ears close to the inlet pipeline, where there is suspected of air leakage, listen to the sound of inhalation, or coat white latex in the suspected place of air leakage, etc.

The self-priming pump is connected to the reservoir, and then the motor is running in normal working condition should be hum... The sound, until the specified mold pressure, now the code spike is click, click, a bit of pressurization, just like the continuous jog mode, the pressure switch is new! What is the reason for Zen Bu, how to solve it, please answer a little more popularly, there are many possibilities.

When the pump starts to work, the impeller will automatically contact the end face of the friction surface, resulting in friction, and the water will come up and cover the vertical, and it is normal to have a sound, and the key will be good for a period of time.

It used to be normal! Later, it was like this, is the voltage low?

Home 220v is not a voltage! If the pressure switch is connected to the short wheel, the motor will work normally, the motor is not broken, the pressure switch is replaced with a new one, the water pressure is also there, and the impeller should not be broken! The gas tank is also vented!

I don't know how many times the pressure switch has been sent low to high! I can't believe it.

You check that the pressure switch contacts are in good contact.

Inspection method: 1. Check the slip bridge to check whether the power supply is falsely connected and whether the power supply voltage is stable. 2. Whether the switch contact contact wheel reed is good, the mechanical contact is opened violently due to frequent closure and breaking, and it will be used for a long time.

3. Check whether the contact contact of the pressure switch is good.

The pressure switch is new! Let's take a look at the return water seal first. Right.

The solution to the self-priming pump rang and stopped is related to the cause of the real town register, different reasons can be used for different solutions, the department has the need to replace the self-priming pump to solve the problem that the self-priming pump rang a land brigade to do the next stop fault.

Summary. Hello flowers, there are generally several reasons why the self-priming pump keeps ringing. First of all, it is generally the inlet and outlet valves of the pump that are not fully opened or closed, resulting in the intake or expulsion of air.

Secondly, it is generally the inlet line of the pump that is leaking or blocked, resulting in the inability to suck in the liquid smoothly. There is also the general effect that the bearing of the pump is worn or the axial clearance is too large, resulting in louder noise and reduced efficiency. It is necessary to conduct a comprehensive inspection of the operation of the pump, find out the problem and solve it in time.

Extended Supplements:1If the inlet water level of the pump is too low, it will also cause the self-priming pump to make a loud noise, and the inlet water level should be adjusted to the appropriate position.

2.If the seals of the pump are worn, deteriorated or damaged, the pump can also increase in noise. At this point, the seals of the pump need to be replaced.

3.In addition, if the installation is not properly filled and vented, it will also cause the self-priming pump to be loud. Irrigation and exhaust should be re-filled to ensure proper operation.

Therefore, the self-priming pump is constantly ringing, and it is necessary to conduct a comprehensive inspection, find the problem and deal with it in time to ensure the normal operation of the pump. <>
