Causes the self suction pump does not have the water:
1. The first use of self priming pump,
2. The water inlet pipe and pump body with air,
3. Self suction pump, the water is longer,
4. Self priming pump operation is not stable, regular time short st

Due to water pump in the now society is more industrial demand, many residential environment partial close to country needs of people use water pump (mostly farmland may house water supply) but on the pump don't know and don't know where to buy, spend m

Mine corrosion multi-stage pump is a through carefully designed to improve after a pump, the pump flow components selected is wear-resistant alloys were produced and. In addition, the pump shaft selection of the balance disc, balance ring made. Multi - st

Three skills of pump selection:
1. The use of pump type selection of pump type,
2. The use of pump performance integrated pump type spectrum,
3. The use of pump performance specifications pump type pump.

Because the screw pump has its own close operation, in the use of inappropriate use of the process is easy to form damage. Notice as follow:
1. Screw pump parking,
2. Screw pump starting,
3. Screw pump operation.

1. Often fatliquoring, electric oil pump for high speed operation, grease easy transpiration. Therefore, it is necessary to the lubrication of the bearing can be kept clean, and pay attention to add and change.

2. Gear pumps often to check and repair,

Centrifugal pump flow control methods:
1. Outlet valve opening adjustment,
2. Bypass valve adjustment,
3. Adjust the diameter of the impeller,
4. Speed control.

0 no protective motor, no special protection, no experiment, but it should be fit for 2.1

1 door more than 50mm solid motor can avoid large area of the human body occasionally accidentally touched or near shell charged or rolling elements. Can avoid th

In this era of rapid development of technology, the pump should also have the goods it must carry out the path and direction.
Metering pump commodity whether small household pumps, built with pump and general pump, is still large petrochemical, electric

Centrifugal pump and axial flow pump flow power function curve is not the same, the minimum flow point of the centrifugal pump in the maximum power, axial flow pump minimum flow point power. When the pump starts to take into account the motor's burst, be

The phenomenon of cavitation in centrifugal pump is different because of the different scale and influence.

Portable light emulsion pump station is a fully hydraulic remote control of small mobile pumping station, the use of high pressure ceramic plunger pump. Implementation of the national coal industry standard MT/T188.1-2006. Comply with the implementation o

The pump at zero flow condition between the pump shaft power between these two, for the extra power of 100% ~ 130%, so mixed flow pump of engine characteristics should also be is between the two pumps, usually choose the pump motor and control valve to op

1. The drive shaft or the motor bearings overheating factors: lack of lubrication or bearing rupture etc.. Solution: fill in the lubricating oil or replace the bearing.

2. Occurrence factors of mixed flow pump water, pump body and a suction tube not f

Mixed flow pump from the shape, structure is the range of centrifugal and axial flow pump in between; mixed flow pump of the pumping principle, impeller of high-speed rotation, mixed flow pump is centrifugal pump centrifugal and axial flow pump push the l

1. Factors of axial force:
1). The front and rear sides of the impeller due to fluid pressure is not the same as the pressure (wheel side pressure is low, high disc pressure) led to the axial force A1, which is the direction of the impeller back to the i

Centrifugal pump primary is composed of a pump body, an impeller, a sealing ring, a rotating shaft, shaft seal box and other components, some of the centrifugal pump is provided with a guide wheel, inducer, balance disc and so on.

Summary of the development of submersible pump: from the consumption status, at present China's table view of consumption has reached the world * * * high level close to a quarter of the global total consumption, per capita consumption of stainless steel

Centrifugal pump is professional oil, land oil tanker, tank truck is the most ideal commodity, and applicable to the ship with a cargo pump, bilge pump, separation can be used for delivery of gasoline, kerosene, diesel oil, aviation kerosene and other pet

Centrifugal pump before the start, the pump filled with liquid. In operation, the liquid in the impeller of the pump follows the impeller to rotate, centrifugal force occurs, the centrifugal force effect of the centrifugal pump is before the start, the pu

Centrifugal pump before the start, the pump filled with liquid. In operation, the liquid in the impeller of the pump follows the impeller to rotate, centrifugal force occurs, the centrifugal force effect of the centrifugal pump is before the start, the pu

Before starting the pump should be to the nipple at the upper filler letter cited by injection of water or soap water, used to lubricate the rubber or plastic bearing, until the normal operation of the pump can be stopped.

Axial flow pump and mixed flow pump in the operation must strengthen monitoring and maintenance work in order to maintain long-term safe operation. Do little or no failure, the failure can also be ruled out in a timely manner.

Mixed flow pump is a kind of pump between the centrifugal pump and axial flow pump. Mixed flow pump than the speed higher than the centrifugal pump, lower than the axial flow pump, generally between 300-500. Its head is higher than the axial flow pump, bu

The mobile pump station has this advantage as follow:
1. Not only can pump water, but also sewage,
2. No irrigation water, can achieve pumping,
3. High suction process,
4. Big flow,
5. Open impeller, can be large diameter debris.
