According to the integrated type hydraulic oil tank, the demands of a closed type hydraulic system and an open type hydraulic system are met at the same time, an oil suction filter system and an oil return filter system are integrated, automatic alarming can be given out when a filter reaches the filtering extremity and the system is pressed and enlarged, and meanwhile a bypass-valve is available and is opened to ensure the smoothness of oil liquid and protect the system. The oil tank is mainly composed of accessories of an oil filling cavity, an oil sucking cavity, a closed type oil filter cavity, an oil return cavity, a filter element set, a by-pass protection valve set, an oil pointer and the like.
Description
Technical field
The present invention relates to a kind of hydraulic system for colliery trackless assistant conveyance hydrostatic transmissions equipment, also may extend to the hydraulic oil container of the hydraulic control system of other type of belt drive, it is a kind of integrated hydraulic fuel tank, this fuel tank can meet the needs of enclosed and open type hydraulic system simultaneously, and has gathered oil suction and oil return filter system.
Background technique
At present, at home in colliery trackless auxiliary conveying equipments, be mainly divided into two kinds of hydraulic machine transmission and static pressure transmissions by its type of belt drive.In static pressure transmission equipment, hydraulic system has been undertaken most functional requirement, as walked, turn to, brake, work and other miscellaneous functions, and system complex, huge and require meticulous.Hydraulic oil container has very important role in hydraulic system, and it is beginning and the end of system, but is easily left in the basket again compared with expensive pump, motor, valve group.
Colliery downhole equipment is owing to limit by tunnel, and General Requirements external form bulk properties is short and small keen-witted and capable, and system simple fault rate is low, easy to maintenance or as far as possible non-maintaining, and the hydraulic system that designs a classics seems particularly valuable.In the existing hydraulic system in colliery, hydraulic oil container generally only uses as an oil storage facility, external high and low pressure filter in a large number, bypass protective gear etc.When open type, closed system exist simultaneously, oil circuit is more complicated, and volume is all huger, can not meet actual requirement.
Summary of the invention
The object of the present invention is to provide a kind of integrated hydraulic fuel tank that integrates open system and closed system.
The present invention adopts following technological scheme to realize:
A kind of integrated hydraulic fuel tank, comprises casing, and fueling cavity, enclosed filtering cavity, oil sucting cavity, oil back chamber and adapter cavity are set in described casing; Described oil sucting cavity one side and fueling cavity UNICOM, its another side and oil back chamber UNICOM; Between described enclosed filtering cavity and adapter cavity, be communicated with; On the sidewall of described enclosed filtering cavity, overflow mechanism is installed; The empty protective gear of anti-suction is installed between described adapter cavity and oil sucting cavity; On described casing, be provided with D mouth, the A mouth of the fuel-displaced parts of master of oil sucting cavity and the C mouth of the fuel-displaced parts of adapter cavity of the main oil-feed parts of B mouth, the oil back chamber of the oil-feed parts of oil filler, the enclosed filtering cavity of fueling cavity.
When work, the cyclic process that the flows to when work of the main fluid of this integrated form fuel tank divides two-part, and fluid refuels in fueling cavity to normal work liquid level from oil filler, fluid through fueling cavity to oil sucting cavity, by oil pump sucking-off, after system, arrive enclosed filtering cavity through B mouth through A mouth.Fluid arrives adapter cavity after enclosed filtering cavity, and C mouth is closed system inlet port, draws enclosed filtering cavity inner fluid, then by arriving oil back chamber through D mouth after systemic circulation, returns after filtering oil sucting cavity and complete oil system circulation.
In the time that oil pressure increases in enclosed filtering cavity, by overflow mechanism, the oil pressure in enclosed filtering cavity is flowed to oil sucting cavity; In the time that oil pressure in enclosed filtering cavity lowers, the fluid in oil sucting cavity adds to rapidly in adapter cavity by the empty protective gear of anti-suction; Guarantee the stable operation of system.
In the existing hydraulic system in colliery, hydraulic oil container generally only uses as an oil storage facility, the invention provides a kind of integrated hydraulic fuel tank, and this this fuel tank of integrated hydraulic fuel tank can meet the needs of enclosed and open type hydraulic system simultaneously, and small volume.This fuel tank has thoroughly solved ubiquitous emptying phenomenon in static pressure transmission, and has avoided the secondary pollution problem of static-pressure system completely.
Integrated hydraulic fuel tank provided by the invention is abandoned hydraulic oil container in complex hydraulic system and is only used as oil storage facility, and filter and protective gear are integrated into fuel tank itself.This integrated fuel tank is made up of fueling cavity, oil sucting cavity, oil back chamber, enclosed filtering cavity etc., and has gathered oil suction and oil return filter system.Realize the function that a hydraulic oil container closed system and open system are moved simultaneously.
The present invention is reasonable in design, can effectively solve the fuel tank problem of complex hydraulic system, and in small-sized conventional equipment, advantage is more obvious, and safeguards simple.
