Abstract
The utility model discloses a hydraulic double pump power driven device with an isolation valve. The device comprises an oil tank, a motor, a first hydraulic pump and a second hydraulic pump, wherein the first hydraulic pump is connected with the oil tank and is electrically connected with the motor through a coupler, the second hydraulic pump is in a parallel connection with the first hydraulic pump, the second hydraulic pump is respectively connected with the oil tank and the motor, the first hydraulic pump and the second hydraulic pump are respectively connected with a first high pressure oil channel and a second high pressure oil channel through a first one-way valve and a second one-way valve, the isolation valve is installed on the oil channel connected between the first hydraulic pump and the second hydraulic pump, and the isolation valve and a controlling system are electrically connected. The device overcomes the defect of being low in efficiency of a valve controlling system and being slow in response and low in precision of a pump controlling system in engineering machinery. Advantages of being high in response and high in precision of the valve controlling system and being high in efficiency of the pump controlling system are adopted comprehensively, and therefore working state of equipment and quality of products are effectively guaranteed. At the same time, the isolation valve can be closed, one hydraulic pump is used singly and works under some special conditions, and the device is wide in application.
Description
Technical field:
The utility model relates to the hydraulic equipment field, relates in particular to a kind of hydraulic double-pump power driving device with separating valve.
Background technique:
In prior art, valve control system and pump control system are originally adopted in the motivational drive of engineering machinery mostly.Although valve control system is corresponding very fast, precision is higher, has the defective of inefficiency; Although and pump control system efficient is higher, corresponding slow, precision is low, through improving, engineering machinery has been used the oil hydraulic pump Power Drive Unit mostly, but mostly is greatly single pump-unit, its work makes easy generation equipment job insecurity, the phenomenon of unstable product quality.
For above-mentioned situation, be necessary to provide a kind of device in fact, overcome the defective of prior art.
The model utility content:
Technical problem to be solved in the utility model is, for above-mentioned prior art situation, provide a kind of efficient high, corresponding fast, precision is high, the hydraulic double-pump power driving device of equipment working stability, constant product quality.
The technical solution adopted in the utility model is:
A kind of hydraulic double-pump power driving device with separating valve, comprise fuel tank, motor, the first oil hydraulic pump: the first oil hydraulic pump is connected with fuel tank, and is electrically connected to motor by coupling; Also include second oil hydraulic pump in parallel with the first oil hydraulic pump, the second oil hydraulic pump is connected with described fuel tank, motor respectively; Described the first oil hydraulic pump, the second oil hydraulic pump connect the first high-pressure oil passage, the second high-pressure oil passage by the first one-way valve, the second one-way valve respectively; On the oil circuit that connects between described the first oil hydraulic pump, the second oil hydraulic pump, separating valve is installed.
Be electrically connected between described separating valve and control system.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has overcome the low defective of valve control system inefficiency slow precision corresponding to pump control system in the engineering machinery, fully utilized valve control system high response highi degree of accuracy and the high efficiency advantage of pump control system, made the working state of equipment and quality of product obtain effective guarantee; At some in particular cases simultaneously, also can use separately a hydraulic pump works by closing separating valve, make purposes more extensive.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
A kind of hydraulic double-pump power driving device with separating valve comprises that fuel tank 1, motor 2,3: the first oil hydraulic pumps 3 of the first oil hydraulic pump are connected with fuel tank 1, and are electrically connected to motor 2 by coupling; Also including second oil hydraulic pump 4, the second oil hydraulic pumps 4 in parallel with the first oil hydraulic pump 3 is connected with described fuel tank 1, motor 2 respectively; Described the first oil hydraulic pump 3, the second oil hydraulic pump 4 connect the first high-pressure oil passage 7, the second high-pressure oil passage 8 by the first one-way valve 5, the second one-way valve 6 respectively; On the oil circuit that connects between described the first oil hydraulic pump 3, the second oil hydraulic pump 4, separating valve 9 is installed; Be electrically connected between separating valve 9 and control system.
