Shenlong Pump News Center

The reason include quality of per part of sewage pump, adequate cooling and lubrication, accuracy installation and pressure, etc.

When there is a foreign body in the impeller channel blockage, will cause the impeller stress, the stress of each part, it will cause the pump vibration.

The reason is pipeline pump rotor balance is reduced, pipeline pump cavitation, the pipeline pump operating under the non design condition

General connection form is to use the external force to counteract the pressure of the medium, to achieve the seal. Use of medium pressure from the form of tight connection, the sealing ring is provided on the inner cone, with the media opposite side int

Ferrule connections, it's connecting and sealing principle is that, when the nut is screwed, the card sets under pressure, so that the blade bite into the tube outer wall, card sets and outside the cone in the inner conical surface of the pressure and th

Threaded connection is a simple connection method, commonly used in small valve

This is the most used in the valve connection form

When the pump itself may have some of the problems are excluded, such as still can not solve the vibration problem, but also consider the impact of external conditions on the pump. Such as: pump based natural frequency and vibration frequency similar caus

The principle of centrifugal pump simple said is impeller rotates at a high speed to drive the blade rotating liquid, due to the action of centrifugal force, liquid from the impeller center rejection to the outer edge of the impeller, the kinetic energy i

Electric regulating valve in the processing or assembling received the influence of process, may cause electric regulating valve inner leakage, main problems or in the limit switch, mainly because of the limit switch action compared with that of the fixed

Check the cable is broken, broken phenomenon. It is necessary to observe the appearance of the cable before use, but also with a multimeter or megohmmeter check whether cable channel. There shall be no oil leakage at the outlet of the cable.

Leakage problem. Submersible pump is characterized by the integration of the pump, and not into the water together, so the leakage problem is one of the important factors affecting the normal operation of the submersible pump.

How do the submersible pump burn? What is the cause?
Grounding fault power supply. There are four core cable of the submersible pump, careful not to take the wrong power line as grounding wire.

Causes of pump vibration include mechanical, hydraulic and electrical power.
Vibration control reflects the mechanical processing technology, the operation level of the mechanical installation personnel, the quality of the water pump operator, the functi

The cause include motor,foundation and pump support,coupling, centrifugal pump impeller, transmission shaft and auxiliary parts, pump selection and operation conditions, bearing and lubrication, pipe and its installation fixed, coordination between parts

In view of the vibration of each component of the pump unit, the causes of vibration are analyzed. From the pump hydraulic, mechanical structure design, to the pump installation, operation, maintenance and other aspects of the measures to reduce the pump

After the water pump is started without water causes: impeller turn right or low speed; horizontal water pipe leakage; nut loose fixing impeller impeller off in the water; impeller submerged in water depth is not enough; impeller in a sludge weed plug. Re

Oil immersed submersible pump is a pump and electric power irrigation equipment integrated three-phase asynchronous motor. With reliable sealing performance, small volume, light weight, no need of pumping station, without irrigation water, the use and the

Talking about the current sewage pump in the purchase process, which is the key to ensure that the machine as scheduled. In fact, sewage pump quality has a direct impact on the future health and safety compliance coefficient index, so usually in the selec

What is electroplating wastewater treatment? The so-called electroplating wastewater treatment is the use of scrap iron inner electrolysis process, the technology is mainly use after activation of industrial scrap iron purifying wastewater. When the waste

There are many reasons for the leakage of the pump, mainly because of mechanical seal leakage.

Submersible sewage pump with the anti clogging performance is why more and more attention? This is mainly due to two reasons: first, the increase in the cost of sewage disposal. Industrial enterprises are trying to reduce the amount of water consumed in t

Deep well pump - flow components together constitute diversion pump casing and impeller, and therefore have a great impact on pump performance, is in addition to a part of the impeller greatest impact on pump performance.

Selection model main by flow ,head ,medium and using environment .

The deep well submersible pump motor and pump are directly connected into the water body working water equipment, it applies to the extraction of groundwater from a deep well, can also be used in rivers, reservoirs, canals and other water pumping projects
