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

Because of the rising prices of domestic materials, so my company from this month, the price of water pump uniform rise. If you have any questions, please contact our customer service. To bring you the inconvenience, please understand

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

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

Axial flow pump is a high speed pump, the impeller flow channel is wider, the cavitation is not serious, the performance of the pump is almost no effect. Only when the cavitation development to a serious stage, will affect the working performance of the p

The axial flow pump in the sewage treatment plant is used as a reflux sludge pump, and the two settling sludge pump is returned to the front end of the biochemical pool and mixed with the water inlet. Return sludge pump is generally equipped with frequenc

Pump cavitation, erosion and damage to the joint effect is always an important problem in the water pump operation, maintenance and management, the traditional materials and surface protection technology can not meet the requirements of anti cavitation an

Deep well pump efficiency refers to the ratio of the actual pumping well liquid production and deep well pump displacement theory. Actual production in order to separate the amount of oil as the basis, the theoretical displacement of the deep well pump is

High temperature hot water pump can be 24 hours a day, water, high water pressure, constant temperature to provide the family with different hot water needs, but also consume the least amount of energy to complete the above requirements of the water heate

The taper of the shaft neck and the ellipse degree is not larger than the diameter of the 1/2000. But shall not exceed the maximum 0.05mm, and the surface shall not have scars, exceed the allowable value of axial bending straightening by mechanical or hea

Pump in the open (open loop) is also known as single stage double suction centrifugal pump, the main features of the medium flow, working principle of pump running head: the impeller installed in the pump shell, and fastened on the pump shaft, the shaft d

1.If there is any small sewage pump failure remember not to let it work. If the pump shaft of the filler to be added in a timely manner, if you continue to use the pump will leak. The direct effect of this is that the energy consumption of the motor can b

1.Must meet the requirements of using the flow and head, which requires the pump operating time point (intersection curve and performance characteristics of the pump device) to keep running at high efficiency range, so that power is both easy to damaged p

Self priming centrifugal pump for the first time before starting to use, only need to pump the pump casing into the 2/3 of water, and then start the pump automatically after the water can be sucked up.

Our production of large double suction spiral case in the open pump, flow 4850M3/H, head 20M, matching power 250KW, the number of 8 sets. The pump shell is made of HT250 material disappear grinding casting, the impeller, ring 304 stainless steel shaft, ma
