Abstract
The utility model discloses a put formula hydraulic tank down convenient to maintain, including oil absorption filter core, hydraulic tank and hydraulic pump, hydraulic tank top portion is provided with the top cap, and the top cap is connected at the inside oil absorption filter core top of hydraulic tank through the connecting rod with the setting, and the bottom of oil absorption filter core is linked together with the hydraulic pump of setting in the hydraulic tank bottom through advancing oil pipe. The utility model has the advantages that: when the hydraulic oil tank is maintained, hydraulic oil does not need to be discharged, the environment is protected, the maintenance is convenient, the time and the labor are saved, the hydraulic oil is not easy to pollute, and the service life of the hydraulic system component is prolonged.
Description
Technical Field
The utility model relates to a hydraulic tank especially relates to a put formula hydraulic tank down convenient to maintain.
Background
The hydraulic oil is a working medium for transferring energy in a hydraulic transmission and control system, has lubricating, cooling and antirust functions, directly influences the performance of the hydraulic system, and the hydraulic oil tank is a special container capable of storing the hydraulic oil and has the functions of dissipating heat and precipitating oil dirt. The hydraulic oil tank can be divided into an upper-mounted type oil tank, a side-mounted type oil tank and a lower-mounted type oil tank according to different mounting positions, wherein the lower-mounted type oil tank is convenient to mount, the hydraulic pump is arranged below the oil tank and has strong suction capacity, and the hydraulic pump is widely used at present. The contaminated hydraulic oil is added into the hydraulic oil tank again, so that the hydraulic system is easy to break down, and the service life of the hydraulic part is greatly shortened.
disclosure of Invention
The utility model aims at providing a need not to put down formula hydraulic tank that hydraulic oil need not to put down during maintenance, be convenient for maintain moreover.
In order to solve the above problem, the utility model discloses a technical scheme is:
The utility model provides a put formula hydraulic tank down convenient to maintain, includes oil absorption filter core, hydraulic tank and hydraulic pump, and hydraulic tank top is provided with the top cap, and the top cap is connected through connecting rod and the inside oil absorption filter core top of setting at hydraulic tank, and the bottom of oil absorption filter core is linked together with the hydraulic pump that sets up in the hydraulic tank bottom through advancing oil pipe.
The hydraulic pump is communicated with an oil return control valve arranged at the bottom of the hydraulic oil tank through an oil return pipe.
The connecting rod can be dismantled with the oil absorption filter core and be connected.
The bottom of the oil suction filter core is communicated with the oil inlet pipe through an oil suction control valve.
The utility model has the advantages that: when the hydraulic oil tank is maintained, hydraulic oil does not need to be discharged, the environment is protected, the maintenance is convenient, the time and the labor are saved, the hydraulic oil is not easy to pollute, and the service life of the hydraulic system component is prolonged.
Drawings
Fig. 1 is a schematic structural view of the present invention;
In the figure, the oil suction control valve comprises a top cover 1, a top cover 2, a connecting rod 3, an oil suction filter core 4, a hydraulic oil tank 5, an oil suction control valve 6, an oil inlet pipe 7, a hydraulic pump 8, an oil return pipe 9 and an oil return control valve.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 1, when the oil absorption filter element 3 needs to be replaced, the top cover 1 is opened, the top cover 1 and the oil absorption filter element 3 connected through the connecting rod 2 are taken out integrally, then the oil absorption filter element 3 is detached from the connecting rod 2 for replacement, and thus, hydraulic oil does not need to be discharged.
example 2
As shown in fig. 1, when the hydraulic pump 7 needs maintenance, the oil suction control valve 5 and the oil return control valve 9 can be closed at the same time, so that the maintenance can be performed without discharging hydraulic oil, because the oil suction control valve 5 and the oil return control valve 9 adopt gate valve structures, in the opening and closing processes, the sealing performance is better than that of a stop valve, the fluid resistance is small, the opening and closing are labor-saving, the sealing surface is less eroded by media when being fully opened, the sealing surface is not limited by the flow direction of the media, the double-flow-direction hydraulic pump has double-flow-direction, the structural length is small, and the application range is wide.
Example 3
As shown in figure 1, when the hydraulic pump 7 needs maintenance, the oil suction control valve 5 and the oil return control valve 9 can be closed at the same time, so that the maintenance can be carried out without discharging hydraulic oil, and because the oil suction control valve 5 and the oil return control valve 9 adopt the stop valve structure, the friction force between the valve clack and the valve body sealing surface is smaller than that of the gate valve in the opening and closing process, the valve is wear-resistant, the service life is long, the maintenance frequency is reduced, and the operation cost is reduced.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
