Including: the characteristics of the media, the media containing the particle diameter of the particle, the amount of content, the media temperature, the required flow pressure piping system data
In a pump is a large general-purpose machinery and equipment, it widely application in petroleum, chemical, electric power, metallurgy, mines, ship selection, light industry, agriculture, civil and defense departments, occupies an important position in th
Pump in the open (open loop), also known as single stage double suction centrifugal pump and its main characteristics for the transmission medium flow, head in the open operation of the pump working principle: the impeller is installed in the pump shell a
The water pump is connected with the motor and pump as a whole, the pivot bearing of the motor rotor is a pump bearing, which is a rigid power transmission to make the pump impeller rotating work pressure reducing valve. Between the pump impeller and the
1. Water pump before use should pay attention to: voltage compliance and electricity safety, because the water pump is working in humid environment, the power switch should be installed on the leakage protection switch.
2. Do not move the pump suction pi
Application of clear water pump:
1. Suitable for garden irrigation, hotels, villas, high-rise water supply and irrigation of farmland, excluding factories, mines, ships and other water
2. Suitable for small flow, high lift, small power occasions.
High temperature medium transport of chemical pump structure, materials and auxiliary system put forward higher requirements, the following talk about the different temperature changes on the cooling requirements of the company and the application of chem
The sewage pump can be equipped with full automatic safety protection control cabinet according to the user's need, and the absolute protection of the leakage, leakage, overload and over temperature of the self sucking non clogging sewage pump is improve
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
