Axial flow pump of the shape is cylindrical. The main components are bell, an impeller, a guide blade body, the water pipe, pump shaft and bearing and shaft seal device and so on.
The sludge screw pump is a single screw pump, its main working component is the eccentric screw (called the rotor) and the inner surface of a double helical screw (said the stator). Its working principle is when the motor drives the pump shaft rotation, t
Single-stage pipeline pump and multi-stage pipeline pump is based on the number of the impeller to distinguish between the:

1. Single-stage pipeline pump:
Single-stage pipeline pump is the only one impeller pump. The advantages of simple structure, sm
Some well pump, especially the submersible pump of high specific speed, at boot time often heard a "boom" sound, the pump shaft suddenly channeling. This is why the original in the well pump, due to the flow of water and water pressure as well as the ro

1. Lift is the vertical distance from the liquid to the pump inlet flange center, refers to the liquid pump unit mass of the import and export of energy difference.

Specific example: if it is ordinary water pump, pump head is 50 meters, 50 meters in fa

Improper selection and operation of the fountain pump is likely to cause vibration. So, what are the potential causes of the occurrence of the fountain pump vibration is how to deal with it?
Soil wells and wells pump straw structure is basically the same, the different point is only the radial dimensions of the soil well pump is not restricted, relatively large, unipolar turn higher, generally only a leaf lost; pump pumping well with small ra
Correctly select the well pump, to extend the life of the pump and water wells, to play the effectiveness of the pump is very important. Selection of the pump not only to achieve the requirements of the flow and head, but also to ensure that the installat
Bearing and bearing under low temperature pump. Bearing in the atmosphere, the general thrust ball bearings; lower bearing for guide sliding bearing, immersed in the medium of work, and lubrication by the media.
Low temperature pump shaft seal is the key components of the pump, at present most of the use of mechanical seal, forms a single face, double face and tandem mechanical seal.Low temperature pump shaft seal is the key components of the pump, at present mos
Low temperature pump has two vertical and horizontal structure. Most low temperature pumps are vertical and double layer shell structures.
Starting, stopping and running requirements of the liquid pump :

1. The liquid pump motor is not installed, the power should be turned on to check the direction of rotation must be consistent with the provisions of the pump rotation direction.

2.
Removal sequence of liquid pump :
1. Liquid pump off the pressure valve in the pipe, removed out of control on the part of the flange bolts or connecting nozzle. Removed a section of pipe, lifting its length to prevent pump prevail.
2. The hydraulic p
Installation requirements for liquid :

1. The liquid pump must be installed vertically in the liquid tank or tank above the fixed bracket.

Pump is a used for liquid delivery tool, corrosion-resistant chemical centrifugal pump is one of a kind, it through the impeller enable flows through the impeller liquid by the action of centrifugal force, and improve the mechanical energy of the liquid,
Because of the centrifugal pump is the impeller on the pump water extrusion formed after vacuum water, so in addition to the impeller leaching in water centrifugal pump and self suction pump, general every time before opening the pump must to pump water f
Submersible electric pump according to the motor waterproof can be divided into dry submersible electric pump, oil filled submersible electric pump, wet submersible electric pump and other three kinds.
If centrifugal cryogenic pump in operation produce noise and vibration, accompanied by flow, lift and efficiency decreased, sometimes even can not work, and maintenance can often be found in the vicinity of the blade inlet edge that have pitted or cellula
The centrifugal pump on the market, according to its structure to can be divided into, single-stage, single suction, single stage double suction cantilever structure. There are also two stage single suction, two stage double suction at both ends of the su
Necessity of speed regulating operation of boiler feed pump :

1. Improve transmission quality. Hydraulic coupling can make the motor of light load starting, low starting current, reducing the starting torque of motor, motor is shortened starting durat
In the multi-stage feed water pump, the water flows in the same water pump casing. At this time the pump pressure is equal to the sum of the impeller pressure. The pumps generally have two kinds of structure: A is of the impeller and vaned diffuser shell
