Description
Technical field
The present invention relates to a kind of constant current amount multiple spot oil supplying device, particularly a kind of static-pressure system is with constant current amount multiple spot oil supplying device.
Background technique
At present, be applied to the most constant pressure fuel feeding that adopt of static-pressure system on a pump, the guide rail, comprise various valves, filter, throttle element composition, this oil supply system complex structure, accuracy of manufacturing require high, install, debugging work load is big, easy break-down, especially the static-pressure system that is applied on the guide rail is various because of pipeline, the fuel tank volume is big, can not with the movement parts servo-actuated, be difficult to realize telecontrol.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of simple in structure, installation, debugging work load little, be easy to realize the static-pressure system constant current amount multiple spot oil supplying device of telecontrol.
In order to achieve the above object, the technical solution used in the present invention is:
Static-pressure system constant current amount multiple spot oil supplying device, it comprises fuel tank, the airtight case lid that can open connection with it is housed at the top of described fuel tank, cover at described fuel tank or closed box and to have the pouring orifice that is connected with oiling device, in fuel tank, be equipped with Pyatyi straight connection type gear pump at least and with the input oil pipe joint and the output oil pipe joint of every grade of corresponding one by one setting of straight connection type gear pump, at least the gear shaft of the adjacent straight connection type gear pump in the Pyatyi straight connection type gear pump links to each other with the medial axis each other, one end of each input oil pipe joint is connected with the oil suction filter and the import of the straight connection type gear pump of its other end and corresponding setting with it is connected, the straight connection type gear delivery side of pump of each output oil pipe joint one end and corresponding setting with it is connected and its other end links to each other with outer pipe on being installed in the fuel tank sidewall, on described outer pipe valve is installed, the power input shaft end of Pyatyi straight connection type gear pump links to each other with device of rotation driving at least.
The invention has the advantages that: adopt this device not need control valve and flow controller, simple in structure, volume is little, from fuel feeding, can with the movement parts servo-actuated, the pipeline weak point can be realized telecontrol, only need to change the counter-rotating that can realize pump into and out of the hydraulic fluid port position of pump, because the pump group immerses in the oil, good cooling results, no leakage of oil increase the service life.
