1.Start the motor, the pressure on the pipeline to be discharged to the rated value and stable after slowly open the outlet valve of the pump, adjust to the required conditions. Idle time should not be too long to avoid "pump, sealing ring dry friction
Preparation before starting :

1.Check the bearing box lubricating grease, filling too much but due to the mixing and heat. If the oil is not enough to make up.
2.Check the anchor bolts fixed connection looseness, the motor ground is good.
1.Import and export pipeline, flow of centrifugal pump impeller partially blocked, the scale deposition in the pump inside. Check the pipe and pump cavity to remove the blockage, re adjust the valve size.

2.The voltage is low. The solution to the prob
1.Pipe, pump block.

2.The voltage is too low

3.Impeller wear
1.Pipe, pump block.

2.The voltage is too low

3.Impeller wear
In the use of self priming pump, the most easily damaged parts are mechanical seals, which is one of the important components of the self suction pump. When the pump mechanical seal is damaged, the transmission of liquid leakage occurs when the phenomenon
1.Check the self-priming sewage pump pipeline and contact loose appearance. By hand or something tumbling self-priming pump, sewage pump is not sensitive to it.
2.As far as possible to control the flow and head of self priming pump in the range of signs

2.As far as possible to control the flow and head of self priming pump in the range of signs
Horizontal centrifugal pump in the installation, there are skills and requirements, as far as possible in accordance with the correct instructions to install, you can effectively avoid the late work may be encountered in the safety and efficiency and perf
1.Lessons of river, lake and sea bottom sand.
2.Draw River, river, lake, sea, reservoirs, fish ponds, power plants and other underwater silt and sand.
3.To draw a variety of stone processing plant powder slurry.
Cement sand submersible pump, pumping sand pump, pump motor and pump hydraulic machinery into the dielectric coaxial work, flow components made of high strength wear-resistant alloy material of the pumps, with better wear resistance.
1. Ten causes the centrifugal pump vibration big reason - - Pump type selection and variable operating conditions;
2.Ten causes of centrifugal pump vibration of the major reasons - bearing and lubrication ;
3.Ten causes the centrifugal pump vibration bi
1.Ten major reasons for vibration of centrifugal pump -- shaft
2.Ten main reasons causing the vibration of centrifugal pump -- base and pump support
3.Ten causes of vibration of centrifugal pump -- coupling
4.Ten main reasons causing the vibration o
Generally, the so-called pump head should contain the pump body and pump cover part. Pump body is mainly connected to the pump rotor, the impeller through the bearings, seal, bearing components connected. The pump cover is a part of the corresponding part
With the development of science and technology self suction pump performance is better than the traditional water pump, self suction pump is a new type of pump in recent years, the research and development of the research and development. Self priming pum
Before the installation of self - priming pump, we should carry out an operation step is gas - liquid mixing test. What is gas-liquid mixing? What should be the operation? Next, we introduce some specific processes.

Gas - liquid mixing, usually, the s
Mechanical seal is one of the common parts of the pump, but if the use or improper installation, will more easily lead to mechanical seal wear and leakage, so we should pay attention to what is convenient, because what will affect the mechanical seal life
We used the self suction pump generally refers to the external mixing type centrifugal pump, impeller rotation to tell he is according to the liquid flow to the vortex shell, so that the pump body to form a vacuum, so self suction pump one-way valve will
1.Check whether the motor running direction is consistent with the direction of the pump running, do not reverse!

2.Pump body shall be filled with liquid to start running, prohibited idling. Self priming pump in the specified range of self suction hei

2.Pump body shall be filled with liquid to start running, prohibited idling. Self priming pump in the specified range of self suction hei
1.Self priming pump by long-distance transport to reach the use of the site, the installation must be checked before the whole machine parts are intact, fasteners should be tightened to check the pump shaft and motor shaft of the concentric degree, if the
High temperature liquid conveying pump by automatic lubrication, without additional lubrication oil, power transmission for small deviation compensation caused by the installation of the elastic coupling, has good cushioning effect on by hydraulic shock.
1.Installation of water pipes, horizontal section or upward:

In this way, the water can be gathered in the water pipe, and the vacuum degree of the water pipe and the water pump is reduced, the water suction head of the water pump is reduced, and the
Multistage centrifugal pump because of simple structure, its application architecture repair convenience, the advantages of high power, is the use of a class of rate pump products widely used in agricultural irrigation, but sometimes there will be no wate
Domestic pressure pump in the use of time, there will be a different fault, to learn to repair their own fault, in order to ensure the stability of their water.
