Multistage pump repair if there are conditions, it is best to look at the manufacturing plant maintenance specifications and the general assembly, to see which special place to pay attention to.

Centrifugal pump is a kind of vane pump, rely on the rotation of the impeller in the rotation process, due to the interaction of blade and liquid, the blade will mechanical energy to the liquid, so can increase the pressure of the liquid, to achieve the p

The key technology of the installation of centrifugal pump is to determine the installation height of the pump. Installation height refers to the water surface to pump impeller center line of the vertical distance, it allows the ceiling should not be conf

According to the fluid flow direction to the impeller distinguish and runoff (centrifugal pump) fluid outflow direction vertical to the axis is along the radius direction outflow; mixed flow pump fluid flow direction and the axis with an angle; axial flow

1. Pump inclined to reduce the elbow. The water pump is inclined to be installed or the spiral case is turned, and the water outlet is opposite to the pool.
2. Shorten the pipeline. Remove 1 meters of steel pipe, 10 hours can save diesel 0.21 kg.
3.

According to the hole diameter, water initial pump type. Different types of pumps on the borehole diameter size have certain requirements, the maximum dimension of the pump to less than the well diameter 25 ~ 50mm. If the borehole deflection, maximum dime

Can be seen, the multi-stage pump is a centrifugal pump which a, the following first introduced the principle and characteristic of the centrifugal pump, and specific comparison, get more difference between the obvious pump from the pump in the classifica

Operation of submersible pump:
1. Voltage anomaly does not boot ,
2. Should not be frequent start ,
3. Pay attention to the change of water level,
4. Found abnormal immediately shut down,
5. To disable the submersible pump to regular boot rust

Operation of submersible pump:
1. Voltage anomaly does not boot ,
2. Should not be frequent start ,
3. Pay attention to the change of water level,
4. Found abnormal immediately shut down,
5. To disable the submersible pump to regular boot rust

Installation rules for submersible pumps :
1. Go through before installation,
2. Right distribution,
3. Two to have levels of leakage protection measures ,
4. Check the motor rotation direction before entering the water,
5. The installation position

Cooling of dry type submersible pump:
In air cooling, water cooling machine.

The cooling water cooling machine, oil machine

Stator casing water external cooling, rotor direct water cooling.

Well with submersible pump according to the internal structure of points for filling water, oil filled, shield and dry four, the motor cavity is filled with the medium and divided into three types: water, oil and air, and shielding type motor stator cavit

The main pipeline in the orchard paved 200 meters DN63, a plurality of micro spray petition 100 meters long DN50 soft belt. The underground water from the wellhead 15 meters, how to choose oil pumping machine? How much lift and flow can be satisfied?

Mixed flow pump is a kind of "pulling" type structure of the pump, check and disassembling the impeller and shaft seal, no and the pump body is connected with the pipeline apart. The pump shaft is equipped with precision machining, with thin oil lubrica

1. With a belt drive, pump and engine pulley with positive. Safety cover should be set outside the belt pulley and the belt.
2. Pump cover should not be directly connected to the elbow. In order to ensure that the inlet velocity distribution is uniform

Pump installation height: the highest on the water surface should not be higher than the lower end of the bearing, the lowest on the surface of the pump depends on the pump allows the vacuum (Hs) (should be reduced branch pipeline loss).

Reasons for low speed of mixed flow pump:
1. The pump itself caused by mechanical failure,
2. Caused by the motor,
3. Human factors.

The installation technology of agricultural water pump is very strict. First, the pump base should be strong, and try to shorten the length of the water absorption tube. Secondly, the water inlet pipe should be sealed and reliable. Valve and hose at the e

In accordance with the provisions of the design, construction, installation and acceptance regulations, specifications and other technical documents and combined pumping station for the specific circumstances, the pumping stations civil engineering and m

The regulator unit is mounted on the top of the motor. Mainly include: planetary gear reducer, spiral adjustment mechanism, digital tube display components, etc.. To the output shaft of the speed reducer drives the adjusting rod, adjust the positive and r

The scope of centrifugal slurry pump is generally used for short distance, low lift concentrate, tailings, ore, slag, sand, coal, sediment and solid slurry materials, lifting and conveying. Directly or indirectly connected in series, in the transmission d

Screw pump at work, after the liquid is drawn into a hermetically sealed space surrounded by the thread and the pump shell. When the active screw rotation, screw pump sealed volume in screw extrusion under increased pressure screw pump, and axial movement

The pipeline pump is a new type of pump, which is a new type of pump, which is used to solve the pressure of the pipeline. It has a great advantage over the current application of the horizontal centrifugal pump.
