1.Of the fire water pipeline must not leak, high sealing, Water Leakage;

2.To prohibit the pump in the long run under the condition of cavitation;

3.The prohibition of the pump in the large current operating conditions, the motor is running over a

Deep well submersible pumps are generally installed in the installation of the use of hose and installation of steel tubes and other two ways. The first is applied to the head is very low (generally less than 30m) of the submersible pump, second kinds of

Sewage pump is a kind of non clogging pump, with a variety of forms, mainly used for transportation of urban sewage, feces or liquid containing fiber. Scraps of paper and other solid particles of the medium, the medium temperature is generally not more th

What are the factors to reduce the outlet pressure of the centrifugal pump? The following one or several factors may constitute a centrifugal pump outlet pressure reduction:
1.Motor rotation,
2.Point to large flow low head offset,
3.Speed reduction,

1.Scraping the exterior appearance and impeller sealing ring and the bearing and other places of accumulated scale and rust, water or compressed air cleaning, blowing.

2. Clean the pump body joint appearance accumulation of grease and rust.

3.Clea

How to go clean the centrifugal pump is the main parts of pump: horizontal centrifugal pump, stainless steel centrifugal pump, fluorine pump, centrifugal pump, chemical pump, etc..

Cleaning is one of the main parts in the work, and the quality of cle

Before the launch will need to view the status of the rolling shaft is not normal, there is no death scene; the impeller range is not normal; cable and cable plugs without rupture, abrasions and broken scene etc.. In operation to pay attention to the inve

1.The water burned down, the pump can not absorb water

The approach is to add a pump and drive shaft.

2.Water blocking

The approach is the deep well pump hanging out from wells, understand water blockage and reinstall.

3.Pump fire into the

1.The water burned down
The approach is based on the request of the deep flow and pump out the water, will be presented for deep well pump with more a series of pumps, and add appropriate pump pipe and drive shaft.

2.The gap is too large in the deep

Lifting pipe thread connection is connected, should add the lubricating oil, should not be filled in flax, lead oil; pipe end and bearing bracket joint (long axis deep well pump or directly attached to the two pipe coupling depth rotation should be equal;

Submersible mixed flow pump and submersible axial flow pump are dry motor. Large pump unit can be installed in various ways, mainly used for farmland irrigation, water lifting, dock drainage, flood control and city municipal water conservancy project, etc

Submersible sewage pump is also called submersible sewage pump, submersible sewage pump is mainly used in municipal engineering, construction, hotels, hospitals, hotels and other industries, for conveying the wastewater, with solid particles and long fibe

Two control methods of fire pump analysis, using the current signal control method, its advantage is to reflect the fault of the motor in a timely manner. And the fault of the motor is the main fault of the pump unit. But this method does not indicate whe

Centrifugal pump in operation, can not be a long time to close the outlet valve:
When the centrifugal pump outlet valve is closed, if the flow is too small, it is only the efficiency of the centrifugal pump will be decreased, the cost of electricity, the

Axial flow pump in the operation of cavitation is a problem worthy of attention. According to the operating conditions, most of the axial flow pump cavitation is more serious. The reason of cavitation is the same as the centrifugal pump.
Axial flow pump

Axial flow pump is generally used to change the angle of the blade angle of the method to adjust the flow, which requires a set of dynamic leaf regulation.

Axial flow pump is generally used to change the angle of the blade angle of the method to adjust the flow, which requires a set of dynamic leaf regulation.

The structure is simple, reliable and easy to use. The pump has good performance, efficiency and power curves, the use of a wide range of closing point of small power, good cavitation performance, so it is widely used in agricultural irrigation and indust

The seal is to prevent the pipeline pump shaft and casing leak sealing device set. A common shaft seal type packing seal, mechanical seal and dynamic seal. The reciprocating pump is usually packing seal. When the transmission is not allowed to leak the me

The fire pump must be approved by the relevant units of recognition can use, for example: in the fire protection system of building fire hydrant system, sprinkler system, foam fire extinguishing system, large space, high water gun spray fire extinguishin
