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。

Pressure fluctuation propagation of a pump turbine at pump mode under low head condition

Pressure fluctuation at the vaneless space and vanes passages is one of the most important problems for the stable operation of a pump turbine. The fluctuation appears in any operating condition. Much research has been done on the pressure fluctuation of hydraulic machinery. However, the details of pressure fluctuation propagation of the pump turbine at the pump mode have not been revealed. The modern pump turbine with high water head requires the runner to be “flat”, which would induce pressure fluctuation more easily than the low head pump turbine. In this article, a high head pump turbine model is used as the research object. As the pressure fluctuation at off-design point is more serious than at the design point, the low head condition is chosen as the research condition. Pressure fluctuation at the vaneless space and vanes passages is predicted by the computational fluid dynamics method based on k- shear stress transport model. The experiment conducted on the test rig of the Har...

Several type of pumps for changing human life

Today we will talk about several type of water pump ,which changes our life. 1, Booster pump :The last decades,people who lives in high building can feel pains caused by the low water pressure,especially in rush hour.But now,the convenience booster pump takes to us become a part of our life. We nearly forget it exist.In nowadays,building is taller and taller,but even on the top of the high cloud bulding,the flow of water is also very stable and strong. 2,Ro booster pump:As ro technology developed,ro booster pump step into our daily life,since the pump appeared ,make water clean and safety is not a hard work,this type of pump helps a lot of people drink clean water,avoid disease,especially some people who is required only drink purified water,do not need to pay too much money to buy purified water,we can get it anywhere.Even in desert,bottle water can be brought easily.some sweet water purified by sea water,how magical pump is it? 3, Aquarium water pump ,fishes which we can see on...

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...
