Pump repair--The power is too large

1,Check the pump whether it is being used over it is rated power,adjust the flow,adjust valve. 
2,If the suction head lift is too high,decline the suction head lift. 
3,If the bearing is lossy,change a new bearing. 
There is noise and shakes with pump system: 
1,Check if the pipe net is fixed,tighten the pipe net. 
2,Check if there is air in liquid,raise suction pressure to exhaust air. 
3,Decrease the vacuum of pipe to prevent cavitation. 
4,If the bearing is lossy,change a new bearing. 
5.The motor is overload,and the motor temperature raises,adjust the motor,the solution is below. 
 This way can help you find problems of centrifugal water pump,coolant pump,aquarium water pump,booster pump,dewatering pumps,dirty water pump,shower pump,even our newest pump--ro booster pump。

Why Ro booster pump in a water treatment system does not work?

Why Ro booster pump does not work?Let's find out the reason. Reverse Osmosis booster Pump is one of the key part of the RO water purification machine,we call it ro booster pump,It is a kind of booster pump be used in the reverse osmosis device, it has the function of self-priming and pressurization. Ro booster pump provide Ro membrane water pressure and water flow,to make Ro rembrane work. Ro membrane is another important component of the RO water purification machine.So Ro water purification machine can give us purifield water. Some times ro booster pump does not work,so the whole system is out of work,there are follow reasons cause the ro booster pump doesn't work: 1,Purifield water tank at a high level or the original water tank is at a low position. 2,Ro water pressure is higher than the protection switch Settings, the controller automatically switched on. 3,Ro booster pump suction pressure is lower than protection switch Settings, the controller automatically discon...

How to exclude the interference from the frequency converter

These problems often occur when you work at regular work and debug the equipment： 1 . When the converter of the heat exchange station is opened , the pressure transmitter shall jump ; 2 . using frequency converter to control the water supply , the voltage transformer is used as a signal for collecting pressure , and the voltage transformer is interfered by the frequency converter ; 3 . When the frequency converter starts up the motor , the voltage change signal is unstable and the jitter is great ; 4 . The voltage transformer ( 4 – 20mA ) shall jump after the frequency converter is started , and the integrated thermal resistance ( 4 – 20mA ) nearby is not affected , and the signal line is not shielded . These phenomena are due to the interference of the frequency converter. Why does the inverter produce interference The inverter comprises a rectifying circuit and an inverter circuit , wherein the input AC power is converted into a DC voltage through a rectifying circuit and a wave loo...

A centrifugal water pump show us your capability

In recent decades, China’s property market has entered a rising rapidly, the purchasing power exuberant state. However, due to the recent weakness in the market, the property market began to gradually slow down, into a stable, and even occasional decline stage. Recently, one of my friends suddenly called me and excitedly told me that he had taken a fancy to a house in the neighborhood,the real estate belongs to Poly property, it is said that the property just opened, it attracted many buyers of onlookers.in just a few days, the house has been sold out.My friend has been on the sidelines all the time, as he has a set of property, not anxious to buy second sets of houses,instead, he chose carefully and wanted to buy one sets around the good evironment,he wanted it is a quality and residential environment are both very good house.I don’t know why he has taken a fancy to this neighborhood recently. My friend was excited to invite me to go with him to purchase procedures,So, we came to t...
