In the separation of indoor air is separated from the outlet pipe to drain, while the water is still by the left and right of the backwater hole flow to the outer edge of the impeller and and the suction pipe air mixed phase. So repeated cycle, gradually

The function of safety valve is a device to protect the safety of pressure vessels and pressure vessels or equipment, and to take off automatically when the pressure is raised to a value of a safety pressure. Safety valve is widely used in chemical, elect

The first possibility of leakage of the mechanical seal is the dynamic and static ring plane wear. Maintenance method: replace the mechanical seal 2, water quality difference containing particles. Due to poor water quality, containing high hydrochloride c

Safety valve action is not flexible refers to the safety valve open, back seat when the action is not flexible, clear or open back seat and other phenomena. The main reason is that:
1.Bumps, napping, rust or burr defect 1, moving parts, assembly and not

Concentrated sulfuric acid pump selection is a common chemical practitioners, in many production processes will be used for concentrated sulfuric acid pump, and this will inevitably involve the selection problems, such as improper selection. The mild pati

No matter it is aircraft, rockets, tanks, submarines, or drilling, mining, trains, ships, or everyday life, everywhere need to use the pump, running everywhere. It is this way, so the pump as general machinery, it is one of the main products in the machin

Known flow, head and efficiency, but also for the shaft power. Between the various performance parameters of the pump there are certain interdependent relationship between can through the test of the pump, respectively, measured and calculated parameter v

After years of development, China's small and medium-sized submersible pump product quality, service life, safety, performance and reliability were the greatly improved, in order to promote a small submersible pump submersible axial flow pump industry em

sually sewage equipment used two types of glass and carbon steel material (carbon steel is 6mm, 8mm, 10mm) so you in the purchase of equipment need to ask supplier material, technology and other conditions are the same and different materials prices will

Currently on the market types of centrifuges and different high-speed centrifuge, low speed centrifuge, refrigerated centrifuge, the most widely used is small capacity low-speed electric centrifuge, routine laboratory instruments, with beautiful shape, la

Because of the high speed of axial flow fan, the wind pressure is large, the cooling effect is greatly enhanced. At the same temperature and load current, the temperature of the main motor is reduced by 12. The temperature of the main motor in summer is n

Motor power, speed is matched with the vacuum pump, can not be changed. Fan installed in the motor spindle, the motor speed determines the fan speed, can not be replaced. Increase the number of fan blades can play a role, but the increase in the number of

1. Motor power, working current, large heat.
2. Fan blade less, resulting in a small amount of wind.
3. Fan speed is low, wind pressure, air volume is small.
4. Vacuum pump motor where the bus voltage is 380V, due to the cable voltage drop and load dis

SZ type water ring vacuum pump with the continuous development of the industry, has been in progress, so that it is also able to better meet the application. And in different environments can better meet the application, so in the use of the process has m

Disc type: due to the same pressure, liquid and gas flow rate is different, the different dynamic and static pressure, driven disc valve action.

Working principle of vertical multistage centrifugal pump
When the motor drives the shaft, full of the liquid in the impeller under the action of centrifugal force, from the impeller center along the blade runner left to the circumference of the impeller

Ready to work
Close the import and export valves, and ensure that the valve can not be opened without permission.
In the pump packing or cover, should make the first pump cooling high temperature to room temperature.
Make motor insulation, prevent moto

Safety valve into the wellbore, the ground pressure, pressure by liquid control pipeline is transmitted to the two sealing packing between pore pressure to the piston, push the piston moves downward, and the compression spring, to open the valve, if the c

Rotary type (such as plug valve, ball valve, butterfly valve) and flexible body type (pinch valve, diaphragm valve) valve can also be used for throttle control, but usually only in the limited range of the valve diameter. In most cases, people usually use

Correct installation of control valves and the correct selection of the same important. Installation quality is related to the operation performance, control quality, safety and cost of the control system, so it should be paid more attention to.
Control

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
