Fountain pump is the use of motor driven centrifugal force will be some liquid, such as the gradual introduction of the surface of the machinery and equipment, in order to create a fountain for people, but also for the surrounding environment to add a bea

1.Check the parts: hot water submersible pump impeller, ring, sleeve, bearing and others are wearing parts. The first part of the pump should be removed, check whether the vulnerability is intact. Use of damage and non qualified spare parts;

Water pump control cabinet with overload, short circuit, phase protection and pump Water Leakage, motor overheating and leakage protection function and complete state display, and have a single pump and pump control mode, multiple standby pump switching m

Electric valve is mainly used for liquid, gas and air flow of the wind system. Electric valve structure is divided into two parts, the upper half of the electric actuator, the lower part of the valve.

Heating system is commonly used to have valve, gate valve, butterfly valve, ball valve, check valve, safety valve, pressure reducing valve, pressure regulator valve, balance valve, regulating valve, etc..
1. Safety valve
2. Pressure reducing valve
3.

1. Ensure that the fluid contained in the maximum particle size does not exceed the maximum safety of the pump through the particle diameter standard.
2. The intake pressure should not exceed the maximum allowable use of the pump pressure, higher than t

Sewage source heat pump in the form of many. According to heat pump directly from the sewage heat, can be divided into direct and indirect two kinds of.
Indirect sewage source heat pump is the so-called intermediate heat exchanger or heat pump loop thr

1.Check wiring is there a problem? There is no loose phenomenon?
2. Check the pump between the various components of the normal?
3. Check the situation of lubricating oil.
4. Check whether the voltage is consistent with the rated.

Mechanical problems or reduce the efficiency of the pump operation, it will cause adverse effects on the entire plant production. The wear ring can provide protection and control of the recovery cycle of the liquid when the pump is operated under abnormal

When the pump head body of the water injection pump is subjected to an alternating load during the operation process, the fatigue crack is generated. The fracture failure caused by the pump head body, the defects of low stress should suddenly brittle frac

Mud pump in the use of the process, which is likely to occur when suction pump does not suction water, suction water slow or pump vibration situation, these water absorption is what caused the failure of it
1. Pump suction is not water, the main reason

As the study of the theory of continuous improvement and test conclusion deepening and accumulation, especially the application of the theory of two-phase flow, sewage pump, slurry pump efficiency and constantly improve the level of inevitable.

Stainless steel multi-stage centrifugal pump pump pump is equivalent to more than one single pump in series, so sometimes less than 2 to 1 still can work, not affect the pump displacement, will only change the pump head.

Low water level protection for submersible pump operation
Submersible pump design is running under the water, the heat of the motor through the immersion in the water heat, so the submersible pump running, the motor must have at least 1/3 immersed in wa

The seal is to prevent the pump shaft and the casing leak and the establishment of the sealing device, seal are commonly used in packing seal, mechanical seal and dynamic seal. The reciprocating pump is usually packing seal. When the transmission is not a

1. The deep well pump before cleaning according to the rules to unload parts, check the foreign body inside the pump, record and analysis of existing problems.
2. After the cleaning is completed, the measurement of each part size, analysis of wear.

Storage of deep well pump:
1. Deep well pump should be stored in a dedicated warehouse, is strictly prohibited in the outdoor placement. Transport and storage should always have the protection of both ends of the thread, effectively prevent foreign mat

After a long trial, the constant pressure fire pump will be insufficient, some even have no oil and other failures, the main reason is too much wear. The wear position of the fire pump is mainly in the active shaft and bushing, the center hole of the pass

After a long trial, the constant pressure fire pump will be insufficient, some even have no oil and other failures, the main reason is too much wear. The wear position of the fire pump is mainly in the active shaft and bushing, the center hole of the pass

1. Scraping the inner surface and the outer surface of impeller and seal ring and bearing place accumulation scale and rust, water or compressed air cleaning, blowing.
2. The shell joint surface cleaning up dirt and rust.
3. Cleaning the water seal

1. Oil seal
2. gasket seal
3. Thread seal
4. Labyrinth seal
5. Packing seal
6. Dynamic seal
7. Mechanical seal

Balance hole is not too large, mainly affect the efficiency of the pump, the following describes the pump axial thrust balance of several methods :
1. Opening balance hole
2. The balance tube
3. Using balanced blade
4. Double suction impeller

Because of its variable delivery, self absorption capacity, can be reversed, can transport the liquid containing solid particles and so on, in the sewage treatment plant, widely used in the transport of water, wet sludge and flocculant liquid. Screw pump

The slurry pump will appear idle phenomenon, usually because the internal pump malfunction phenomenon. Therefore, we want to avoid the slurry pump slurry pump idling phenomenon leads to excessive wear phenomenon, we need to avoid this idle phenomenon, tim
