The installation position of the pump should be satisfied with the requirement of the height of the suction on the vacuum, the foundation must be level and steady, so that the rotation direction of the power machine is consistent with the direction of the

1. Parts cleaning, dry, according to the decomposition of the inverse order of the assembly.
2. Close to the end of the impeller parts of the bearing no straight groove, bearing end bearing with straight groove bearing.

Submersible pump before use, to respond to submersible pumps, switches and cables and other equipment to conduct a comprehensive inspection.

Reasons: the middle shaft and the intermediate gap is too large
Solution: change the intermediate shaft and intermediate, reduce the gap

If a valve body of the channel is not the same diameter (often the seat is smaller than the diameter of the flange connection), known as the path contraction.
The size of the parts can be reduced, the required force of opening and closing can be reduced

High viscosity pump can transport high viscosity, high concentration of no solid particles or small particles of the lubricating medium, high efficiency, stable performance, long service life.

Single screw pump can also transport high viscosity, high concentration of solid particles and suspended solids media; applicable range of G series single screw pump according to the material can be divided into the following three types: general pumps, f

Currently used in the treatment of printing and dyeing wastewater pretreatment process mainly include: grid, mesh, grit, regulating water quantity and water quality, cooling and process. According to different printing and dyeing wastewater treatment, dif

Textile printing and dyeing wastewater has the characteristics of water, high concentration of organic pollutant, alkaline, water quality variation and so that is difficult to deal with industrial wastewater, wastewater containing dyes, sizing agents, add

WQ type submersible sewage pump, JYWQ jywq products are mobile installation and fixed installation of two basic forms. Can be designed according to the national standard drawing 01S305 "small submersible sewage pump selection and installation" selectio

Solenoid valve and electric valve is driven by electricity, then control valve switch, compared to the pneumatic valve speaking, the power of control valve called electric valve, then for the solenoid valve and electric valve, the two have what different.

Ball valve ball is floating in the medium pressure, the ball can produce a certain displacement and pressure in the export side of the sealing surface, to ensure that the export side seal.
Floating ball valve structure is simple, good sealing, but the ba

Ball valve can be divided into: floating ball valve, fixed ball ball valve, track ball, V type ball valve, three-way ball valve, stainless steel ball valve, forged steel ball valve, unloading ash valve, anti sulfur ball valve, three-way ball valve, gas dy

Ball valve installation
1. Remove the protective cover on both sides of the flange, the valve is fully open in the state to wash clean.
2. iInstalled before the required signal (electricity or gas) to carry out the whole test (to prevent the impact of t

General pumping station project, the pump outlet check valve selection, should follow the following principles: the pump outlet pipe diameter smaller pipe, that is, DN<50mm, should be used to lift check valve.

1. swing check valve is generally installed in the horizontal pipe: for the caliber DN~80mm check valve, can also be installed in the vertical or upward inclined pipe.
2. Straight lift check valve should be installed in the horizontal pipe; vertical lift

According to media wear bushing series wear a 0.6MPa1.2MPa general 0.4MPa0.8MPa serious 0.2MPa0.4MPa2. of single screw pump speed choice: single screw pump because of its structural features, most in the delivery of high viscosity liquids and particles co

Control valve, also known as the control valve, it is a process control system with power to change the flow of the device. Regulating valve by the actuator and valve (regulator).

YW liquid sewage pump in the liquid, the pressurized environment, underground fluid flow to the ground, for people to use, but liquid pump in use process, vibration caused by noise to cause harm to the staff, also will affect the liquid pump work efficien

Trouble of electric pump include this as follow:
1. Electric pumping liquid pump electric motor does not run after the electric pump
2.Electric pumping liquid pump electric pump after the occurrence of abnormal sound and do not rotate or turn very slow

Submersible pump installation, the first should check whether the rotation of the pump shaft is flexible, if it is found that the pump shaft rotation is not flexible, there is impact sound, pump shaft radial shaking, should be excluded after the installat

Safety valve some used in the water tank, the safety valve of water or other liquid at room temperature should check with the water pressure, so that it can be more realistic conditions, because water is incompressible, so sensitive in reaction to pressur
