There are many factors to consider in the installation of a water pump, one of the more important being the installation of the pipework. Pumps and pipes are often used together and the two need to be considered in conjunction with each other in order to achieve the best results. So what do you need to pay attention to in the installation of the pump pipeline? The following Ace lobe pump 's will tell you.
1、When installing the inlet pipe, the horizontal section is horizontal or upwardly curved
Doing so will cause air to gather in the inlet pipe, reducing the vacuum of the water pipe and pump, lowering the pump's suction head and reducing the water output. The correct approach is that its horizontal section should be slightly inclined towards the direction of the water source, not horizontal, let alone upwards.
2、Many elbows used on the inlet pipe
If more elbows are used on the inlet pipe, this will increase the local resistance to water flow. And the elbow should be turned in the vertical direction, not in the horizontal direction, so as not to gather air.
3、The water pump inlet is directly connected to the elbow
This will cause uneven distribution of the water flow through the elbow and into the impeller. When the inlet pipe diameter is larger than the 143c water inlet of the pump, an eccentric reducer should be installed. The flat part of the eccentric reducer should be installed on top and the bevelled part on the bottom. Otherwise, the air will be gathered, the water output will be reduced or the water will not be pumped on, and there will be a crashing sound, etc. If the water inlet pipe is equal to the diameter of the water inlet of the pump, a pipe should be added between the water inlet of the pump and the elbow, and the length of the straight pipe should not be less than 2 to 3 times the diameter of the water pipe.
4、The bottom section of the inlet pipe fitted with the bottom valve is not vertical
If installed in this way, the valve will not close on its own, causing leaks. The correct installation method is: the inlet water pipe fitted with the bottom valve, the bottom section should preferably be vertical. If it cannot be installed vertically due to topographical conditions, the angle between the axis of the water pipe and the horizontal plane should be above 60.
5、The inlet of the inlet pipe is not in the right position
(1) into the water pipe inlet from the inlet pool bottom and pool wall distance is less than the inlet diameter. If the bottom of the pool has mud and sand and other dirt, the distance between the inlet and the bottom of the pool is less than 1.5 times the diameter, which will cause poor water intake when pumping or suck in mud and sand debris, blocking the inlet.
(2) When the water inlet of the inlet pipe is not deep enough, this will cause the water surface around the inlet pipe to swirl, affecting the water inlet and reducing the water output. The correct installation method is: the water inlet depth of small and medium-sized water pumps shall not be less than 300~600mm, and large water pumps shall not be less than 600~1000mm.
6、The outlet of the water pipe is above the normal water level of the outlet pool
If the outlet is above the normal water level of the outlet pool, it increases the pump head but reduces the flow rate. If the water outlet must be higher than the water level of the sink due to topographical conditions, an elbow and a short pipe should be installed at the mouth of the pipe to make the water pipe siphon type and reduce the height of the outlet.
The above six points are the precautions for the installation of water pump pipeline, hope it will help you!
