Analysis of Common Problems in Stainless Steel Fountain Pump

Stainless steel fountain pump into the water pipe and pump the air

(1) the pump is not filled before the start of adequate water, and sometimes looks to fill the water from the vent hole overflow, but not turn the pump shaft air completely discharged, resulting in a little residual air in the inlet pipe or pump.

(2) with the water pump in contact with the horizontal section of the water flow direction of the application of more than 0.5% decline in slope, the end of the pump inlet connection to the highest, not completely level. If the tilt up, the inlet pipe will retain air, reducing the water pipes and pumps in the vacuum, affecting water absorption.

(3) the pump packing has been worn due to long-term use or packing pressure too loose, resulting in a large number of water from the filler and the pump shaft sleeve gap in the jet, the result is outside the air from these gaps into the pump's internal, Affecting the lifting of water.

(4) into the water pipe due to long-term potential underwater, pipe wall corrosion holes, water pump work after falling, when these holes exposed surface, the air from the hole into the public water pipes.

(5) into the pipe bend at the cracks, water pipes and water pump at the junction of a small gap, are likely to make the air into the water pipe.

Stainless steel fountain pump pump speed is too low

(1) human factors. There are some users of the motor with the original damage to the random drive coupled with another motor, resulting in a small flow, low head and even the consequences of not Sheung Shui.

(2) the pump itself mechanical failure. Impeller and shaft fastening nut loosening or bending deformation pump shaft, causing the impeller to move more directly friction with the pump, or bearing damage, are likely to reduce the pump speed.

(3) power machine repair not working. Motor winding loss due to the winding, and maintenance of winding turns, wire diameter, wiring method changes, or maintenance failure is not completely ruled out factors will make the pump speed change.

Suction too

Some water sources are deep, some of the water outside the terrain than the flat, while ignoring the pump to allow suction, resulting in less water absorption or simply not the result of Sheung Shui. To know the pump suction can be established at the vacuum is limited, the absolute vacuum suction is about 10 meters high water column, and the pump can not establish an absolute vacuum. And the vacuum is too large, easy to pump the water vaporization of the pump work. So the centrifugal pump has its maximum allowable suction, generally between 3-8.5 meters. When installing the pump must not only simple and convenient.

Stainless steel fountain pump out of the water flow in the resistance loss is too large

Some users have been measured, although the reservoir or water tower to the water surface of the vertical distance is also slightly smaller than the pump head, but still a small amount of water or not to mention Sheung Shui. The reason is often too long pipes, pipes and more corners, the water flow in the pipeline resistance loss is too large. The reason is often too long pipes, pipes and more corners, the water flow in the pipeline resistance loss is too large. In general, 90 degree elbow pipe resistance than 120 degrees, each 90 degrees bend head loss of about 0.5-1 meters, every 20 meters of pipe resistance can head loss of about 1

Meter. In addition, some users are free to pump into and out of the pipe diameter, which also has a certain impact on the head.

Stainless steel fountain pump and other pump factors

(1) the bottom valve does not open. Usually due to the pump for too long, the end valve washer was sticky, no gasket of the bottom valve may rust.

(2) the end of the valve filter network is blocked; or bottom valve potential water sludge layer caused by filter plug.

(3) impeller wear serious. Impeller blade wear and tear by long-term use, affecting the pump performance.

(4) gate valve can be faulty or blocked check valve will result in reduced flow or even pumping not Sheung Shui.

(5) leakage of the outlet pipe will also affect the amount of water.
