The tubular pump deep well pump is directly connected to the bottom of the oil pipe column, which is composed of a pump barrel assembly, a plunger assembly, a fixed valve assembly, a fixed valve fixing device and a fixing valve salvage device.

The foundation excavation in the construction of the city, and auxiliary buried underground pipes, underground water is the first problem to be solved, and the key to solve the problem is to use the pump can easily be extracted from the ground water and

Submersible pump is a vane pump, depending on the rotation of the impeller in the spinning process, due to the interaction of blade and liquid, blade mechanical energy to the liquid, the liquid pressure can increase, to achieve the purpose of conveying li

1.Remove the water pump from the engine.
2.The front axle nut submersible pump, unscrew and remove the water pump cover, impeller and seal pressure.
3.Check if the seal, the seal is bakelite, wear is not too serious, can be put in a glass or dry clo

The problem of slurry pump wear is mainly manifested in the:
1.The impact of work efficiency. Due to the gap between the impeller and the pump body mutually wear, the pump volume efficiency decreases gradually with the increase of flow surface wear and

The problem of slurry pump wear is mainly manifested in the:

Generally speaking, a special pump is a special kind of pump which is used to transport the liquid medium, the use of the requirements and the use of occasions and so on. Such as the transportation of impurities, suspension, volatile, high viscosity, stro

Cause of damage analysis:
1. Sand abrasive wear and abrasion
2. Liquid flow erosion damage
3. Cavitation damage

Viscous fluid flow through the leaves will have conducted, the profile loss, loss of two, enveloping the secondary flow loss and radial clearance loss.
1. Leaf type loss;
2. Torus loss;
3.Two flow loss;
4. Radial clearance loss

Axial flow pumps can be divided into two types according to the installation method, which can be divided into common seat type and block type. The motor and the transmission device are directly arranged on the pump structure, and the whole pump is shared

Pump effective power can be through the flow and head, transmission medium density to calculate, and to calculate the axial power to know the efficiency, then how to calculate the pump efficiency?

In order to better understand and understand the pipeline pump, it is necessary to introduce the various parts of the pipeline pump.
1. The motor: the electrical energy into mechanical energy of the main components.
2. Pump seat: is the main body o

Mud pump is the key equipment of drilling fluid circulation system, which is generally used to transport the drilling fluid under high pressure to the bottom of the well, so as to cool the drill bit and carry cuttings. Because of drilling hole depth, cutt

Parts and transmission of the media contact, will be a certain corrosion or other effects, it is necessary to select the appropriate materials and components according to the transport media.

The liquid pump is a special type of centrifugal pump, cast iron shell, the lower end of a spiral chamber (scroll), indoor pipette and mounted on the vertical shaft turbine wheel. The liquid pump is used for conveying the intermediate mixed acid, the conc

1.No liquid supply, inadequate supply of liquid or insufficient pressure :

1).There is no water injection or the appropriate exhaust
The elimination of measures: check the pump shell and the pipelines are all filled with liquid entrance.
2).Spee

1.The weight of the drilling pump is large, it is difficult to adapt to the requirements of the modern portable drilling rig, which restricts the movement of the drilling rig.
2. The stroke is short, the flushing time is high, and the drilling pump is n

Check valve, also known as one-way valve or check valve, its role is to prevent the
flow of media in the pipeline back. The bottom valve pump water check valve also
belongs to class.

Opening and closing pieces by medium flow and power to ope

For the self suction pump:
Should be placed in a better place to run, in order to facilitate the rapid heat dissipation, reduce motor temperature. Otherwise, a long time to run, very easy to burn the motor. Such as farmers in the use of a pump, the cover

Sewage pump to optimize the home environment plays a vital role in the use of the sewage lifting device at home, of course, hope that the use of time can be as long as possible. Now to introduce how to maintain the sewage pump.

As is known to all, when the centrifugal pump casing has the air, the density of the air is much smaller than that of the liquid, and the centrifugal force is produced. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is
