How to increase the self-priming capacity of the centrifugal water pump

First method(simplest one)
Self-priming sewage pump vacuum pump is arranged in the water pipeline, water pump start before the vacuum pump starts to pump water pipe Neixianbu
with water, to ensure that the water pump, quick start.
This type of water absorption requires a perfect automatic control system to ensure normal work.
Second method(more simple)
The self – priming pump reduces the water inlet pipe curve , the fall height and the horizontal interval.
Third way( Trouble, but it works.)
The self-priming pump is equipped with a water suction tank in front of the pump. In this way, a suction tank should be installed on the pump suction
pipe. Before the first operation of the pump, the tank should be filled with water manually, and after the first operation the tank should be
stopped. Since the intake pipe of the suction tank is higher than the water level inside the pipe,the water in the tank will not flow back into the
pool, so the water can be stored in the tank, and because the water suction tank outlet pipe (that is, the suction pipe of the pump) is lower than
the water level inside the pipe. Therefore, it can ensure that the water absorption pipe of the pump is covered with water, and when the pump is
running again, the water in the water tank is pumped away by the pump, and the water in the pool is added to the water absorption tank under the
action of atmospheric pressure. Enter the pump through the pipes in the tank tank.
The fourth way
Self-priming sewage pump suction pipe. The suction end of the valve is installed at the end of suction end of the valve is actually a check valve, it
can only guarantee the flow by the pool into the suction tube can not turn the clock back, so if the water pipe is full of water, despite the
elevation axis pump the water level above the pool, but because there is the role of the water suction end of the valve. The tube into the pool water
will not enable the suction tube has been filled with water to ensure the pump can automatically, quickly start.
The fifth way
In the pump structure , for example , the self – priming pump in the figure below directly combines the vacuum impeller with the centrifugal pump .

Causes of Electric Motor Burning by Water pump

1. First, find out whether the motor burns the bearing (mechanical fault) or the coil (electrical fault). If it is the fault of burning coil, it is mainly caused by overcurrent, sometimes too high or too low voltage will also cause the coil to heat and short circuit, so check that the voltage when running is too different from the rated voltage.There may be several reasons for over-current short-circuiting: A. the equipment is overloaded to make the motor run for a long time at rated or over rated current. In particular, the starting current of the motor is 3-5 times that of the rated current. Therefore, we should try to avoid running with load or full load when starting the equipment (mainly depending on the matching allowance of rated current and normal operating current of motor). B, the motor works in a wet working environment. The insulation of the coils should be checked before the motor starts. The insulation requirements of different voltage grades are also different.

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...

How much is the stainless steel water pump?

We are very concerned about the price of the stainless steel centrifugal pump? How much money of stainless steel pump, in fact, this has a great relationship with product quality,some stainless steel pump like Grundfos,the price is higher, the quality is good. But there are also some stainless steel water pump,like Gelaili pump,the quality is good, but the price is not so high,it’s like buying a steak with the cabbage money. There are some small factories, the quality of their water pump production is not stable, the user experience is very poor, the price is very cheap, but in the process of using, maintenance costs have far exceeded the saved money when the pump was brought down. Therefore, how much is the stainless steel pump, really depends on the quality of the product, there is no enterprise willing to do business at a loss. How much is the stainless steel pump, stainless steel pump manufacturers and production experience affected price.Grundfos pump manufacturing history, c...
