Abstract

The invention discloses a sand-discharging float-type submersible pump with a double-oil-chamber sealing structure. The submersible pump comprises a supporting device and a submersible pump device, wherein the submersible pump device is mounted at the upper end of the supporting device. When a motor operates to pump water, water flow quickly enters from a pump head, so that the flow velocity around the pump head is increased; a first impeller rotates after the water flow is increased, the first impeller rotates to drive a rotating rod to rotate, the rotating rod drives a first conical head, the first conical head rotates to drive a second conical head, and the second conical head rotates to drive a second stirring blade to rotate through a first rotating assembly, so that the water flow velocity in an inner cavity of an annular groove is increased; and after the water flow velocity in the annular groove is increased, heat in an inner cavity of an oil seal device is taken away, so that a first oil seal chamber and a second oil seal chamber are prevented from being damaged by high temperature.

Description

technical field [0001] The invention relates to the technical field of buoyant type submersible pumps, in particular to a buoyant type submersible pump capable of discharging sand and having a double oil chamber sealing structure. Background technique [0002] Submersible pump is a kind of water lifting equipment, mainly composed of pump body, impeller, and submersible motor. The submersible pump is a derivative product of the submersible pump. On the basis of the submersible pump, it also includes a buoy device, so that the whole device can float in the water, avoiding the submersible pump from pumping the sediment at the bottom of the pool, and also has a certain shielding effect on the sundries on the water surface. , and the submersible pump is designed to solve the tightness when operating in harsh environments, thus producing a submersible pump with a double oil chamber sealing structure. The heat brought by the operation, so as to achieve the effect of cooling. [0...
