we provide advice of submersible pump installation,submersible pump working,submersible pump troubleshooting,submersible pump stopped and other pump technology articles.
In order to stabilize the pressure, usually in front of the system, the gas storage pressure vessel is connected in parallel. Some calibration units have been equipped with electric or pneumatic compressor, its own source of pressure. Some equipped with m
Duct obstruction treatment method is check the motor of the air duct, breeze tract obstruction due to check, remove air duct in the accumulation of dust and grease, maintain a smooth flow of air duct. The speed of the motor recovery normal temperature ris
Diaphragm pump at work, crank connecting rod mechanism driven by the motor, drive the plunger reciprocating motion, the movement of the plunger through the hydraulic cylinder in the working fluid (oil, and spread to the diaphragm to diaphragm back and for
To master the technical requirements of balance pipe diameter. Balance tube removed to check the gasket is appropriate, the inner diameter of the balance tube gasket should be greater than the balance of the pipe diameter, the aperture will cause the thro
Mastery of the pump assembly sequence. First remove the above, after the demolition of the following, first remove the outside, after the demolition inside, the first demolition of the assembly, the assembly sequence and the removal of the order of the co
In the operational efficiency and save energy consumption, the use of automatic control valve is an indispensable part of the traditional industrial sector commonly used manual valve, pneumatic valve, the installation cost and efficiency are less than the
1. Timing positioning check pump operation situation; the instrument display is normal, whether the pump is in the best state operation;
2. Check the bearing temperature is normal, increased or decreased to slowly as well, and found out the reasons for t
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
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
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.

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.
