High speed pipeline pump is a new type of chemical process pump. It can replace reciprocating pump and multi-stage centrifugal pump.

1. Clean the pump around.
2. In the bearing box into the right amount of grease. (has been injected before the factory. Run 500 hours plus)

The efficiency of centrifugal pump is the product of three kinds of efficiency, mechanical, volumetric and hydraulic. The efficiency of the pump group is the product of pump efficiency and motor efficiency.

Water pump is one of the most important equipment in the sewage treatment industry, and how to improve the performance of the sewage pump under the condition of ensuring the normal operation of the sewage pump?

The submersible pump is very common in our life, especially in agricultural irrigation, industrial water supply, drinking water and other mountainous plateau used more frequently.

The choice of deep water pump if you choose to model the lift is too high and the actual use of a large gap in the head, it will cause the motor over current, there will be heat and even burn the motor.

Mine submersible pump operation current assembly caused by the protection switch trip, the main reasons for the current major following:
1. The pump to the wrong
2. Mining submersible pump flow is greater than the normal range

Self-priming pump according to the principle of operation is divided into gas-liquid mixing (including internal and external mixed type), water ring wheel, jet type (including liquid jet and gas jet) several categories.

1. Go through before installation
2. Right distribution
3. To have two leakage protection measures
4. Check the motor rotation direction before entering the water because there are many types of submersible pumps are turning and reversing can be out

Although the aluminum ion in our country has not stipulated emission standards, but research shows that excessive intake of aluminum ions will directly destroy people inside nerve genetic material DNA function,

1. No flow after startup, no pressure
2. Pump vibration
3. Lack of flow or head low
4. Changing the color of lubricating oil
5. Increase in the loss of lubricating oil
6. Pump side mechanical seal leakage

1. No flow after startup, no pressure
2. Pump vibration
3. Lack of flow or head low
4. Changing the color of lubricating oil
5. Increase in the loss of lubricating oil
6. Pump side mechanical seal leakage

Now the water pump is used more and more widely, has been applied to many sewage treatment engineering projects has also been a lot of people are familiar with, but two kinds of pressure on the equipment you may explain is not very understanding, here to

Each product in after a period of time, there will be failures, for after a period of time there may be a decrease in operating efficiency, resulting in decreased efficiency of the pump what are the reasons,

1. The pump head is too high, the current regulation; the outlet valve, reducing the current flow driving
2. Impeller or pipeline blocked; check whether there are obstacles.
3. Air or entrance pipeline leakage inspection; entrance pipeline has no cavi

Water hammer is the phenomenon of pressure fluctuation caused by the sharp change of liquid velocity in pressurized pipeline. In the pipeline system, the gate is opened and closed rapidly, the water pump suddenly stops, the water pump opens and closes the

1. Pump does not absorb water, pressure gauge, vacuum gauge pointer pendulum
2. Pumps and suction vacuum gauge shows high vacuum
3. Pressure gauge pressure, but no water pipe
4. Low flow

Single stage centrifugal pump is the only one of the pump impeller, the maximum lift is only 125 meters; multistage centrifugal pump refers to two or more than two of the pump impeller, the maximum can lift more than 125 meters;

1. Sewage pump work, pay attention to the situation of water level drop, sewage pump shall not work outside the water.
2. When used to find sewage pump stopped, less water, noise and heat protector frequent take-off and other phenomena, should stop the

Pipeline centrifugal pump (i.e. ISG vertical centrifugal pump ISW horizontal centrifugal pump, some single-stage XBD fire pump is the pipeline centrifugal pump installation, they generally are similar) in the application of life is too broad

Boiler water supply equipment to ensure safe and reliable water supply to the boiler, the boiler room should have spare water supply machinery, in addition to the boiler room are 1 power load or reliable power supply, or because of power outages and stop

1.The sealing ring and the bearing shells in horizontal multi-stage centrifugal pump seat respectively with the fastening screws.
2. The mouth ring installed in the middle and tighten screws fixed.
3. Guide vanes set on the guide vane and screw the re

With the gradual popularization of well submersible pump and application of the field of expansion, submersible submersible pump must adapt to more different environmental requirements.

1.Ensure safe operation of key equipment
2.Replace lubricants and wear parts regularly
3.Strict catalyst metering pump operating procedures
4.To enhance the maintenance of the pump
