Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Technical solution provided by the invention is illustrated in more detail below with reference to Fig. 1 to Fig. 6.
As shown in Figures 1 to 6, this compact profile shaft flow hydraulic axial plunger pump includes:
Shell 10；
Rear cover 20 and shell 10 surround to form installation space, and cylinder body 30 is equipped in installation space；
Transmission shaft 40 across shell 10 and protrudes into the closely connection of installation space and cylinder body 30, and the transmission shaft 40 passes through cylinder
Body 30 is simultaneously contacted with rear cover 20, and the transmission shaft 40 is set as oil distribution shaft structure, and in 30 docking location of transmission shaft 40 and cylinder body
Equipped with chute 41；
Hydraulic lock repairing check valve 50 and safety overflow valve 60 are integrated on rear cover 20.
The present invention protects a kind of compact profile shaft flow hydraulic axial plunger pump, is a kind of compact profile shaft flow for yacht
80 formula diverter of hydraulic axial plunger, integral structure layout is compact, and 20 integrated hydraulic of rear cover locks repairing check valve 50 and safety is overflow
Valve 60 is flowed, self-locking and defencive function can be provided to execute oil cylinder；The diverter is the diverter of manipulation one, which is grasped by people
Power oil sources is provided after work and realizes that turning function, general diverter are to need to provide power by other oil sources to turn to realize again
To function；The pump uses axis flow form, plunger pump volumetric efficiency low problem when can solve the slow-speed of revolution, and axis is matched
It flows compact compared to disk distributing construction.
In the present case, the compact profile shaft flow hydraulic axial plunger pump power density is big, shell 10, rear cover 20, transmission shaft
40 etc. be all using aluminum material, and whole pump is light-weight, but pressure is suitable with the diverter of equal volume.
