Shenlong Pump News Center

Its structure is similar to the cut-off valve, the valve body and the valve flap are the same as the cut-off valve. The upper part of the valve and the valve cover the lower part of the processing of a simple guide sleeve, valve guide Jane can the free va

Instrument wind line blocking. Because the valve throttle effect in wind instrument branch line, the wind line where the stolen goods blocked accumulation. The instrument air pressure is too low, can not fully open valve fully closed, even the valve does

Mud pump is generally in rural areas is mainly used for the river mud, manure, river water and slurry feed, pumping irrigation, instead of shoulder shoulder, and for flood, drought resistance, it can be used for river, river mud, manure production, simple

Because the use of conventional pneumatic valve, inevitably a piping, solenoid valve and the compressor in order to match, while the electric valve is a motor-driven, easy to install, and electric valves installed with the original factory lines can be co

To clockwise rotate the handwheel counter clockwise, the spool to move up to the full open position, at this time, medium pressure greatly reduced, the impurities can be discharged directly from the valve orifice area and the inverted vortex formed at the

Should strictly check the dynamic ring and the static ring relative friction between the sealing surface, any slight scratches scratches and other defects are not allowed. All other parts, including a pump body, impeller, seal cavity in the assembly shoul

Should strictly check the dynamic ring and the static ring relative friction between the sealing surface, any slight scratches scratches and other defects are not allowed. All other parts, including a pump body, impeller, seal cavity in the assembly shoul

According to statistics, pump mechanical seal leakage of about 95% is due to the seal end face friction caused by. In addition to maintaining the sealing surface parallel, mainly the material problem of friction pairs.

Centrifugal pump is the use of pumping equipment will be the centrifugal pump and suction pipe in the air pumping out, the liquid suck up. Pumping gas equipment available hand press and mechanical vacuum pump (often for water ring vacuum pump), vacuum pum

Bearing clearance does not meet the requirements. Such as the bearing inner ring and pump shaft, the bearing outer ring and bearing body with too loose or too tight, can cause bearing fever. (with too tight will make the bearing rotation is not flexible;

Preparation before starting:
1. Test motor steering is correct, from the motor at the top of the pump to see clockwise rotation, the test time is short, so as not to make mechanical seal dry wear.
2. Open the exhaust valve so that the liquid is filled w

After the installation of toggle pump shaft, impeller should be no friction sound or blocking phenomenon of pump pump should be overhauled.

Under the normal operating pressure of the equipment, the valve and the valve seat sealing surface occurs more than the degree of leakage, the leakage of the safety valve will not only cause the loss of media. Also the media will continue to leak to the d

Due to the change in the direction of the flow of media, there are four kinds of effects on the pneumatic control valve
1. The valve pressure before and after P1, P2 exchange, unbalanced direction of action of the force Ft or size change;
2. The flow di

In general, I am a pump or vertical sewage pump compared to the sewage pump has the following advantages:
1.Compact structure, small floor area.
2.Convenient installation and maintenance
3. Continuous running time.
4. Does not exist in the cavitation

Centrifugal pumps in operation, the leaking problem, little part is due to normal wear and tear or reached the long service life, most attributed to in the actual operation condition of mutation and operation, improper maintenance and other reasons caused

When you buy sewage pump. You need note the information as follows:
1. Submersible sewage pump flow
2.WQ submersible sewage pump head
3. Sewage submersible pump power supply voltage
4. Submersible sewage pump size and manner

We should how to carry out maintenance and normative operation in each parts of the pipeline, pipeline transportation equipment is not only the maintenance, workers in work practices, only in this way can the conveying line normal operation, but also pay

Oil pump's role is to ensure that the diesel oil in low pressure oil passage of circulation, and the supply of adequate quantity and pressure of fuel to the fuel pump, the oil amount should be 3-4 times the full load maximum injection fuel amount. Oil pu

In the pipeline to pump configuration do not force will be forced into the pipeline installation. If such a configuration pipeline will bring the pump unit to bring the stress out of control, and caused the deviation between the pump and the motor, the pi

ZX self suction pump before starting the preparation and check of mechanical seal service life have a crucial impact. Check the pump shell liquid storage is higher than the impeller on the edge. If insufficient. From the mouth of the pump shell liquid dir

Ordinary steel in sodium chloride solution and sea water, salt water corrosion rate is not too high, are generally required to use paint protection, all kinds of stainless steel also has a very low corrosion rate, but may be localized corrosion caused by

There are many reasons for the leakage of the pump, mainly because of mechanical seal leakage. Shanghai long pump for details of pump mechanical seal Water Leakage causes and solutions.

Centrifugal pump with its simple structure, easy to use and convenient maintenance, high efficiency and become the most widely used in agriculture, a pump, but also because of the water and it is very annoying.

Water pump commonly used motor for 2 pole, 4 pole, 6 pole, deceleration motor and speed control motor. The same type of pump maintenance under constant flow and motor speed lower pump head lower, outlet pressure smaller, so high lift pump generally choose
