This screw type deep-well pump is like this work, by giving electrical power, by motor driving screw arbor assembly action, what the subsequently continuous rotation by screw arbor assembly continued will discharge from water outlet from the liquid that water intake enters into the pump housing, realize suction and the discharge process of water pump.And the radially bore of the pump housing is 4～8 centimetres, can adapt to the needs of operation when well head is less, makes simultaneously the volume of screw type deep-well pump can be less, lighter.
In above-mentioned a kind of screw type deep-well pump, described link one comprises the bearing one that is set on the machine shaft and the universal joint that links to each other with machine shaft one end, described bearing one is fixed in the pump housing by bearing support, and the other end of this universal joint links to each other with screw arbor assembly.Bearing one can the positioning motor rotating shaft, and bearing support is used for bearing one is fixed in the pump housing.Universal joint can couple together machine shaft and screw rod, realizes rotating synchronously.
In above-mentioned a kind of screw type deep-well pump, described screw arbor assembly comprises the screw sleeve that is fixed in the pump housing and the screw rod that is located in the screw sleeve, and an end of this screw rod links to each other with universal joint.Screw rod rotates in screw sleeve, continues liquid inner chamber by screw sleeve in the pump housing is transported to water outlet, discharges by water outlet at last.
In above-mentioned a kind of screw type deep-well pump, described link two comprises the bearing two that is set on the machine shaft the other end, and described bearing two is fixed in the pump housing.Bearing two can the positioning motor rotating shaft, makes things convenient for the rotation of machine shaft in the pump housing.
Compared with prior art, the pump housing of this screw type deep-well pump radially bore is 4～8 centimetres, than other deep-well pumps, has greatly improved the Applicable scope of this screw type deep-well pump, and volume is less simultaneously, quality is lighter, and is very convenient when using and carrying.
