Shower tower circulating vertical pump pump use precautions-common misconceptions

　　Shower tower circulating vertical pump is a kind of engineering plastics PP/PVDF injection molding made of vertical centrifugal pump, with acid and alkali corrosion, oxidation resistance, no water can be idling characteristics, more used in the field of waste gas treatment in the exhaust gas tower, painting, biological deodorization, pickling, printing and dyeing, circuit boards, the electronics industry, and many other fields, the shower tower circulating vertical pump in the use of the process of common misunderstandings are there?

　　Shower tower circulating vertical pump pump use precautions

　　1, the inlet of the inlet pipe is not the right orientation

　　① water inlet from the inlet pipe into the pool bottom and pool wall interval is less than the diameter of the inlet, if the bottom of the pool sediment and other dirt, the inlet from the bottom of the pool interval is less than 1.5 times the diameter of the inlet, it will form a pumping water into the water is not smooth or sucked into the sediment debris, blocking the inlet.

　　② water inlet depth of the inlet pipe is not, this will cause the water around the inlet pipe vortex, affecting the water inlet, reduce the amount of water, the correct device is: small and medium-sized pumps into the depth of water shall not be less than 300 ~ 600mm, large pumps shall not be less than 600 ~ 1000mm.

　　2, set up the bottom valve, the inlet pipe is not the lowest section of straight

　　If this device, the valve can not close itself, the formation of water leakage, the correct device is: equipped with a bottom valve into the water pipe, the next best is straight, such as terrain constraints can not be straight device, the water pipe axis and the horizontal angle should be more than 60 °.

　　3, inlet pipe elbow on the road

　　If more elbows in the water inlet pipe, will add some resistance to water flow, and elbows should be turned in the straight direction, not allowed to turn in the horizontal direction, to avoid the collection of air.

　　4, the installation of water inlet pipe, the level of the horizontal section of the horizontal or upward warping

　　This will make the air collection in the water inlet pipe, drop the vacuum of the water pipe and pump, make the pump suction head drop, water output cut, the correct practice is: the horizontal section should be slightly skewed to the direction of the water source, should not be horizontal, and shall not be cocked upward.

　　5, continuous plating vertical circulation pump inlet and elbow directly connected to the

　　This will make the water flow through the elbow into the impeller when the distribution is uneven. When the diameter of the water inlet pipe is larger than the water inlet of the pump, it should be equipped with a bias reducer, some of the plane of the bias reducer should be installed on the top, some of the slant should be installed underneath, otherwise, the collection of air, the amount of water will be cut down or the water will not be pumped, and there will be a sound of impact, etc. If the water inlet pipe and the diameter of the water inlet of the pump are equal, a tube should be added between the water inlet of the pump and the elbow, and the straight length of the tube should not be less than 2-3 times of the diameter of the water pipe.

　　6、Continuous plating vertical circulation pump outlet above the normal water level in the outlet pool

　　If the outlet is above the normal water level of the outlet pool, although it adds the pump head, but cuts the flow, such as terrain conditions, the outlet is necessary to be higher than the water level of the outlet pool, it should be installed in the mouth of the pipe elbow and a short pipe, so that the water pipe becomes siphon, drop the height of the outlet.
