Abstract
The utility model discloses an oil supplementing device of a guide overflow oil liquid auxiliary rotary motor. The oil supplementing device of the guide overflow oil liquid auxiliary rotary motor comprises a rotary motor, a guide pump and an oil return system. The oil supplementing device of the guide overflow oil liquid auxiliary rotary motor is characterized in that the guide pump is connected with a guide overflow valve, and the guide overflow valve is communicated with an oil opening supplementing pipeline of the rotary motor and the oil return system. The oil return system is connected with the guide pump by a counterbalance valve. When the rotary motor needs to supplement oil, the oil return system and the guide pump overflow oil liquid and supply oil, so that the oil supplementing device of the guide overflow oil liquid auxiliary rotary motor can effectively prevent the rotary motor from being emptied, ensures normal operation of an excavator, is stable in performance, and meets working requirements.
Description
Technical fieldThe utility model belongs to the hydraulic crawler excavator technical field, is specifically related to the recharging oil device of the auxiliary rotary motor of a kind of guide's overflow fluid.
Background technologyThe excavator rotary motor of prior art stops can being rotated further because of inertia after action; this moment the oil-in fuel cut-off; the repairing mouth is introduced the fluid of oil return system; prevent from inhaling empty; the protection motor; but when motor rotary speed was too fast, oil return system fluid was not enough to supply with the rotary motor repairing, caused that motor is impaired, the lost of life.
Summary of the inventionThe purpose of this utility model is to solve excavator oil return system fluid to the technical problem of rotary motor repairing deficiency, provides the recharging oil device of the auxiliary rotary motor of a kind of guide's overflow fluid, to overcome the deficiencies in the prior art.
The recharging oil device of the auxiliary rotary motor of a kind of guide's overflow of the utility model fluid, it comprises rotary motor, pioneer pump and oil return system; Its main points are to be connected with precursor overflow valve on described pioneer pump; Described precursor overflow valve is communicated with repairing mouth pipeline and the oil return system of rotary motor; Described oil return system is in parallel with pioneer pump by counterbalance valve.
The back pressure that described counterbalance valve produces is the direct oil return of overflow fluid that prevents pioneer pump when rotary motor needs repairing.
When the utility model needed repairing when rotary motor, oil return system and pioneer pump overflow fluid is fuel feeding simultaneously, can prevent effectively that the rotary motor suction is empty, guaranteed the excavator normal operation, and job requirement is satisfied in stable performance.
Description of drawingsAccompanying drawing is the utility model operating principle schematic diagram
In figure 1, pioneer pump 2, precursor overflow valve 3, rotary motor 4, oil return system 5, counterbalance valve
The specific embodimentWith reference to the accompanying drawings, the utility model it comprise rotary motor 3, pioneer pump 1 and oil return system 4; Be connected with precursor overflow valve 2 on described pioneer pump 1; Described precursor overflow valve 2 is communicated with repairing mouth pipeline and the oil return system 4 of rotary motor 3; Described oil return system 4 is in parallel with pioneer pump 1 by counterbalance valve 5.
The back pressure that described counterbalance valve 5 produces is to prevent when rotary motor 3 needs repairing, the direct oil return of overflow fluid of pioneer pump 1.
The utility model is when the working connection A of rotary motor and B fuel cut-off, and oil return system 4 and pioneer pump 1 overflow fluid are given the rotary motor repairing simultaneously, can prevent effectively that rotary motor 3 from inhaling emptyly, guarantees the excavator normal operation, and job requirement is satisfied in stable performance.
