Oil pump suction and pressure, the plunger in the plunger set in the reciprocating movement to complete. When the plunger is located in the lower position, the two oil hole in the plunger sleeve is opened, communicated with the oil plunger cavity and the
Water source heat pump technology is low temperature heat utilization of the earth's surface in shallow water in the absorption of solar energy and geothermal energy and heat pump principle, through a small amount of high energy input, a kind of technolo
Oil pump is a common tool used in the production of life is widely used. An oil pump from the purchase to the use of the need to go through a lot of links. The biggest link is the installation of the oil pump. General pump installation has professional te

The function of the pump suction chamber is to lead the liquid in the water inlet pipe to the impeller evenly. There are three common forms of inhalation:

1.Conical tube suction chamber

2.Ring type suction chamber

3.A semi spiral suction chamb
1.The end of the valve can not open. Is usually due to horizontal pump in the open set aside a long time, valve gasket is stuck, no washer valve may be rust.

2.Filter mesh bottom valve is blocked; or potential water valve at the end of the sludge laye
1.Horizontal open pump speed is low :
1).Artificial factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.
2).Mechanical failure of the
1.Horizontal in the open pump before the start of the filling is not enough water, sometimes looks like the water has been poured from the vent overflow, but did not turn the pump shaft to the air completely discharged, resulting in a little air left in t

The use of non clogging self suction sewage pump is of great significance to the maintenance and maintenance of the pump and the service life of the pump. Again good equipment, if you do not know how to maintain and maintenance, will be scrapped in advanc

Suction is too large :
Some of the water is deep, some of the surrounding terrain is relatively flat, while ignoring the pump allows suction process, resulting in less water absorption or not the result of water suction. To know that the vacuum degree of

2.Mechanical failure of the pump itself. Impeller and pump shaft fastening
1.Water inlet pipe and pump body with air

2.Pump speed is too low

3.Suction process is too large

4.Other factors influence
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

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
