Abstract

The invention discloses an integral light manual pump which comprises a steering wheel, a pump shaft, a pump body, plungers, an oil distribution shaft, a cylinder body and a rear cover. The pump body and the rear cover are matched to form a pump cavity. The pump shaft is arranged in the pump cavity. The left end of the pump shaft penetrates out of the pump cavity. The steering wheel is arranged at the left end of the pump shaft. The right end of the pump shaft is sleeved with the cylinder body. The pump shaft is in interference fit with the cylinder body. A plurality of plunger sleeves are arranged on the cylinder body. The front end of the oil distribution shaft is located in the cylinder body. The plungers are located in the plunger sleeves. A pump body oblique face is arranged in the pump body and is of a reinforcing rib structure. The pump body oblique face and the pump body are integrally formed through finish casting. The pump body oblique face is rotatably sleeved with a retainer plate. The front ends of the plungers are connected to the retainer plate. The pump body is made of aluminum alloy. The pump body of the integral light manual pump is made of aluminum alloy, and an original all-steel structure is replaced. The pump body oblique face is of the reinforcing rib structure, so that the weight is reduced. In addition, the pump body oblique face and the pump body are integrally formed through finish casting, the structure is compact, and the size is small.

Description

technical field [0001] The invention relates to the field of ship steering gear, in particular to an integral portable human pump. Background technique [0002] With the development of small ships such as small fishing boats, tugboats, traffic boats, patrol boats, lifeboats, tourist boats, and ferries, marine human hydraulic steering gears have gradually replaced chain-driven human steering gears. There are following problems in the manpower hydraulic pump that existing domestic hydraulic steering gear uses: 1, all steel parts manufacture, and weight is heavier. 2. The coaxiality of the pump shaft, cylinder body and oil distribution shaft is too low, and the service life is short. 3. The processing of the integrated valve block is complicated, the cumulative error is large, the safety factor is low, and the seal connected to the back cover of the pump body is easy to leak. Contents of the invention [0003] The object of the present invention is to provide an integral po...
