Abstract
The invention discloses an oil compression system for a hydraulic motor. The oil supplementing system comprises the hydraulic motor and an oil tank. The oil tank is respectively connected with the liquid inlet end of a first one-way valve and the liquid inlet end of a second one-way valve through an oil supplementing pipe. An energy accumulator is connected with the oil supplementing pipe and is connected with an oil supplementing oil tank. The liquid outlet end of the first one-way valve is connected with a first port of the hydraulic motor, the liquid outlet end of the second one-way valve is connected with a second port of the hydraulic motor, the first port is connected with the liquid inlet end of a first overflow valve, the liquid outlet end of the first overflow valve is connected with the second port, the second port is connected with the liquid inlet end of the second overflow valve, and the liquid outlet end of the second overflow valve is connected with the first port. Due to the fact that the energy accumulator is added on the oil supplementing pipe, a large amount of oil can be timely supplemented to fill an inner cavity of the hydraulic motor when the hydraulic motor is reversed or stops suddenly, the empty cavity can be avoided, a plunger in the hydraulic motor is protected, and normal work of the hydraulic motor is not affected.
Description
Technical field
The present invention relates to a kind of oil-supplementing system for oil hydraulic motor.
Background technique
Along with the fast development of infrastructure construction processes such as China's traffic, the energy, big-and-middle-sized engineering machinery demand and recoverable amount increase continuously fast in recent years.In numerous engineering machinery, particularly in the import equipment, adopt the oil hydraulic motor transmission very general, as the girder transportation vehicle of rock tunnel(ling) machine, shield structure, big ton, crane etc., oil hydraulic motor has big, the characteristics stably of moving of starting torque, and it realizes stepless change easily, has obtained using widely in engineering machinery walking and rotary system.Yet, adopt fluid motor-driven than heavy load, in commutation or when stopping suddenly, because inertia is big, the repairing pipeline is long, easily cause generation cavitation in the chamber of oil hydraulic motor, thus the plunger of damage oil hydraulic motor inside.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of oil-supplementing system for oil hydraulic motor is provided, to solve existing fluid motor-driven than heavy load, when commutating or stopping suddenly, because inertia is big, the repairing pipeline is long, easily cause producing cavitation in the chamber of oil hydraulic motor, damage the problem of oil hydraulic motor internal piston.
The objective of the invention is to be achieved through the following technical solutions:
A kind of oil-supplementing system for oil hydraulic motor, comprise oil hydraulic motor and fuel tank, described fuel tank by the repairing pipeline respectively with the liquid feeding end of first one-way valve, the liquid feeding end of second one-way valve is connected, be connected with accumulator on the described repairing pipeline, described accumulator is connected with the repairing fuel tank, the outlet end of described first one-way valve is connected with first port of oil hydraulic motor, the outlet end of described second one-way valve is connected with second port of oil hydraulic motor, described first port is connected with the liquid feeding end of first relief valve, the outlet end of described first relief valve is connected with second port, described second port is connected with the liquid feeding end of second relief valve, and the outlet end of described second relief valve is connected with first port.
Further, described accumulator is spring loaded accumulator.
Beneficial effect of the present invention is; described a kind of oil-supplementing system for oil hydraulic motor is simple in structure; be easy to realize; by setting up accumulator at the repairing pipeline; in the time of or stopping suddenly in the oil hydraulic motor commutation, in time replenish the inner chamber that a large amount of fluid are full of oil hydraulic motor, avoid producing cavitation; thereby protected the plunger of oil hydraulic motor inside, and do not influenced the oil hydraulic motor proper functioning.
Description of drawings
Fig. 1 is the schematic representation of a kind of oil-supplementing system for oil hydraulic motor of the present invention.
Among the figure:
1, oil hydraulic motor; 2, first relief valve; 3, second relief valve; 4, first one-way valve; 5, second one-way valve; 6, repairing pipeline; 7, accumulator; 8, repairing fuel tank.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of a kind of oil-supplementing system for oil hydraulic motor of the present invention; In present embodiment, a kind of oil-supplementing system for oil hydraulic motor, comprise oil hydraulic motor 1 and fuel tank, described fuel tank by repairing pipeline 6 respectively with the liquid feeding end of first one-way valve 4, the liquid feeding end of second one-way valve 5 is connected, be connected with accumulator 7 on the described repairing pipeline 6, described accumulator 7 is spring loaded accumulator, it is connected with repairing fuel tank 8, the outlet end of described first one-way valve 4 is connected with the first port a of oil hydraulic motor 1, the outlet end of described second one-way valve 5 is connected with the second port b of oil hydraulic motor 1, the described first port a is connected with the liquid feeding end of first relief valve 2, the outlet end of described first relief valve 2 is connected with the second port b, the described second port b is connected with the liquid feeding end of second relief valve 3, and the outlet end of described second relief valve 3 is connected with the first port a.
The present invention is by setting up accumulator 7 at the repairing pipeline, and this accumulator 7 links to each other with near the distance oil hydraulic motor 1 repairing pipeline 6, and fluid comes from repairing fuel tank 8 in the accumulator 7.Oil hydraulic motor 1 commutation or when stopping suddenly, because load inertia, make the oil hydraulic motor 1 one end hydraulic fluid port pressure generation high pressure that sharply rises, the other end can produce negative pressure, when oil hydraulic motor 1 first port a pressure during greater than the second port b, the unnecessary fluid of the first port a is transported to another pipeline by first relief valve 2, and the fluid in the accumulator 7 enters oil hydraulic motor 1 by second one-way valve 5 through the second port b, can in time replenish enough fluid; When oil hydraulic motor 1 second port b pressure during greater than the first port a, the unnecessary fluid of the second port b is transported to another pipeline by second relief valve 3, fluid in the accumulator 7 enters oil hydraulic motor 1 by first one-way valve 4 through the first port a, thereby in time replenishes enough fluid.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
