Temperature control valve can not be used for a long time to do. Please close the valve before and after shutdown. When installed, the temperature control must be installed before the filter high mesh control valve.

Vertical sewage pump and sewage vertical pump is the same. Why? Here need will come up in terms of the vertical, sewage pump according to the appearance with vertical and horizontal, the main models: WQ (QW) submersible sewage pump, GW pipeline sewage pu

Non clogging submersible sewage pump should be managed and used, and regularly check the insulation resistance between the electric pump winding and casing is normal.

No water after the pump starts
1. There is no liquid in the pump.
2. Suction pipe leakage
3. Impeller and pipe blockage
4. Pumps to the wrong
5. Suction height exceeds the specified requirements (4-5m)
6. To pump the liquid inside the tank
7. Elimi

Vortex pump is for pumping water and physical and chemical properties similar to liquid water, using liquid temperature shall not exceed 80 degrees centigrade, commonly used in boiler feed water facilities, in shipbuilding, textile, chemical industry, met

The liquid film between the end face of the mechanical seal is used to lubricate the end face and take away part of the friction heat, according to the working principle, the leakage is absolute, and the trace amount of the leakage is normal. For volatile

When the pump voltage is low, the pump into the water close to the power supply, the pump does not appear or the water is very slow, should be taken to start running, and then put into the normal operation of the water.

After the opening, due to check the electric pump and accessories die not complete. Choose the pump nameplate parameters meet the operational requirements.

The device comprises a diaphragm type air pressure tank. Booster pump, electric control box, instrument and piping accessories, used in Multistory and high-rise building with requirements of pressurization of the fire hydrant system and automatic sprinkle

Hot water pipeline pump is the most commonly used pump, large amount, and the maintenance is convenient, but very new customers, just pump with friends sometimes put forward such a question, my pump just bought, the installation is very strong, why is not

Determine the direction of rotation. Connects the pump and the motor before must be individually to determine the motor rotation direction, because of the slight reversal will also caused the accident, the pump and motor damage, so before the start must d

1. The model specification of the electric valve controller is fixed, and the grounding terminal on the rear panel must be grounded reliably.
2. A controller and valve electric device circuit number is the same, the cable according to the same terminal

The reason may be due to the high temperature of the pump bearing:
1 no lubricating oil, grease or lubricating oil, grease.
2 lubricating oil, grease use or save time is too long,
3 the lubricating oil quality is poor, does not play the role of lubrica

Hot water circulating pump is a centrifugal pump model of a product. Heat pump temperature in 120 degrees or less, the installation is divided into vertical and horizontal 2. Water circulating pump failure is mainly no water, inadequate flow, noise vibrat

Trouble shooting method for rotary vane type vacuum pump:
Rotary vane vacuum pumps in operation, if the improper operation, often malfunction, such as rotary vane vacuum pump vacuum degree drop, injection, smoking, oil seal leakage, noise, etc., and pump

The structure and working principle of reciprocating pump
Main components: pump cylinder, piston, piston rod and suction valve, discharge valve.
Principle: when the piston moves from left to right, negative pressure is formed in the pump cylinder.

Different types of pumps, the performance of the form of failure is not the same, but in general, there are several common characteristics:
1. Inadequate flow
2. Power consumption is too large
3. Violent vibration or noise of the pump body
4. The driv

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
