What should I do if the water pump isn't coming on?

High pressure pump as part of the rear osmosis system, acting as a pumping part, if the water doesn't come, the entire rear osmosis system won't be suitable to filter the water, so the part of high pressure pump shouldn't be undervalued. moment I'll talk about how to do when the high- pressure pump can't pump water?
There's air in the bay pipe and pump body
1, the pump isn't filled with enough water before starting, occasionally it seems to fill the water has overflowed from the bleed hole, but didn't turn the pump shaft exchange air fully discharged, performing in a little air residue in the bay pipe or pump body.
2 、 The vertical section of the bay pipe in contact with the pump should have a downcast pitch of0.5 or further against the direction of water inflow, and the end connected to the bay of the pump is the loftiest, not fullyhorizontal.However, air will be stored in the bay pipe, reducing the vacuum in the pipe and the pump and affecting the water suction, If it's cocked overhead.
3 、 The quilting of the pump has been worn or the quilting is pressed too approximately, causing a large quantum of water to be ejected from the gap between the quilting and the pump shaft sleeve, with the result that the air from outside enters the innards of the pump through these gaps, affecting the water lifting.
4, into the water pipe because of long- term implicit aquatic, the wall erosion of the pipe holes, the water face after the work of the pump continues to fall, when these holes exposed to the water face, the air from the holes into the people into the water pipe.
5, into the water pipe bend at the crack, into the water pipe and the pump connection there's a small gap, are likely to make the air into the water pipe.
Alternate, the pump speed is too low
1 、 The mortal factor. There are some druggies because the original motor is damaged, it's arbitrarily equipped with another motor driven, performing in the consequences of small inflow, low head and indeed not on the water.
2, the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or pump shaft distortion and bending, performing in further impeller shift, direct disunion with the pump body, or bearing damage, are likely to reduce the speed of the pump.
3, power machine conservation doesn't work. Motor due to winding burned, and loss of captivation, conservation in the winding turns, line periphery, wiring system changes, or conservation in the failure to fully remove factors will also make the pump speed change.
4, the suction range is too large. There's a limit to the vacuum that can be established at the suction harborage of the water pump, and the suction range of the absolute vacuum is about 10m water column high, while it's insolvable to establish an absolute vacuum in the water pump. And the vacuum is too large, easy to make the water in the pump vaporization, the work of the pump isn't good. thus, each centrifugal pump has its maximum admissible suction range, which is generally between 3-8.5m.
5 、 The resistance loss in the bay and outlet pipes of water inflow is too large. The channel is too long, the water pipe bend, will beget the water in the channel resistance loss is too large, also although the perpendicular distance from the force to the water face is lower than the pump head, but still lifting the water is small or can't lift the water.
The impact of other factors
1 、 The nethermost stopcock can not be opened. generally it's because the pump has been left for too long, the nethermost stopcock gasket is wedged, the nethermost stopcock without gasket may rust.
2, the nethermost stopcock strainer net is blocked or the nethermost stopcock is potentially blocked in the sludge subcaste in the water.
3. The impeller is poorly worn. The impeller blades are worn out by long- term use, affecting the pump performance.
4 、 Faulty or blocked gate stopcock can beget the inflow rate to drop or indeed not pumping water.
5 、 Leakage in the outlet pipe will also affect the quantum of water lifted.
