Water pump

Abstract

The invention discloses a water pump which comprises a pump bracket, a pump body, a pressurized-water mechanism and a water storage device. The water storage device includes a water storage tank; an air inlet valve is arranged at the upper part on the lateral wall of the water storage tank, and an aqueduct is arranged at the bottom part and is communicated with a check valve arranged at the bottom part of the pump body; and water inlet pipes are arranged inside or outside the water storage tank. The invention can be pumped without adding water during the later use only through injecting and starting circulating water for the first time, thereby achieving the self-absorbing and pumping purpose of 'one-time water diversion and permanent pumping'. A sealing pump cover is additionally arranged at the upper part of the pump body; the pressurized-water mechanism is improved and arranged into a piston, a connecting rod, a swinging rod and a pressure rod; a connecting shaft is arranged on the swinging rod and fixedly connected with the swinging rod, two ends thereof are supported on sealing end covers on the left lateral wall and the right lateral wall of the pump cover, wherein one end cover at one end is sealed, and the other end extends out of the sealing end cover and is fixedly connected with the pressure rod. The improved water pump can improve the pumping lift, enlarge the use scope, and extract the vacuum in containers, so as to be more widely applied. The water pump not only can be driven manually, but also can be powered by applying wind power, water power and electromechanical devices or animal power.

Description

technical field [0001] The invention relates to a water pump, in particular to a water pump with self-priming function. Background technique [0002] At present, the pumps used for some domestic water in rural areas, cities or construction sites generally use manual pressure pumps, which are single-body piston reciprocating. In the process of use, it is necessary to add priming water in advance to pump water. When pumping water, the piston moves up to lift the deep underground water into the pump body. When it goes down, the water in the pump body opens the valve through the piston hole and rushes to the upper part of the piston, and flows out naturally from the pump port. The pump has only suction, but no head, small flow, low pressure, can be used for general domestic water, not for sprinkler irrigation and large amounts of water. Contents of the invention [0003] The purpose of the present invention is to propose a self-priming water pump with simple structure, which ...
