Abstract
The utility model provides a group oil returning filter device of a hydraulic engine power system and is characterized in that: a port of an oil case is fixed with a ring-shaped cushion block, the cushion block is provided with a filter box, the bottom of the filter box is provided with an enclosed base plate, the circumference of the filter box is provided with a strain screen, the upper port of the filter box is provided with a cover board, the cover board is provided with a flange oil-returning pipe and a joint oil-returning pipe for group oil returning in the power system, an upper sealing cushion and a lower sealing cushion is separately provided between the filter box and the cover board as well as between the cushion blocks and thus resolves the issue that how to filter the impurities in the oil circuit and the impurities are inconvenient for cleaning after having returned to the oil box. Additionally, the utility model has the advantages of a simple structure, lower costs and oil-returning in multiple pipelines at the same time.
Description
Technical field
The utility model belongs to the hydraulic press technical field, particularly relates to a kind of hydraulic press power system and concentrates oil-returning filtering device.
Background technique
Adopt oil pump to carry out transmission at present known hydraulic press, and be provided with clutch release slave cylinder, kicker cylinder, power system and power system and concentrate structures such as oil return apparatus, power system concentrates oil return apparatus to be made up of each return tube, cover plate, fuel tank.Oil after hydraulic press oil cylinder back warp is crossed each operation element and carried out work cycle by pipeline directly flows back to fuel tank through return tube, can cause secondary pollution like this, impurity band oil sump tank in the system of being about to, the result can influence the work of oil pump, and cleaning needs during impurity earlier the oil in the fuel tank is put only, dismantle all screws on the lower cover plate then, return tube, cover plate are removed, clear up the impurity in the fuel tank at last.This shows the defective that this power system concentrates oil return apparatus to exist to be influenced oil pump work and clear up the impurity inconvenience.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of filter in the oil return impurities and cleaning impurity easily the hydraulic press power system concentrate oil-returning filtering device.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic press power system is concentrated oil-returning filtering device, comprise fuel tank, be installed in the cover plate on the reservoir port, the flange-type return tube that is installed in the cover plate upper end and pipe joint formula return tube composition, described reservoir port end is fixed with the ring-type cushion block, the Rose Box that side face has filter screen also is installed on the cushion block, also is separately installed with sealing gasket and lower seal pad between Rose Box and cover plate and the cushion block.
Advantage and the good effect that the utlity model has are: owing at the tank drainback place Rose Box is installed, after after a while, when the impurity in the needs cleaning fuel tank, dismantle all screws on the lower cover plate earlier, then return tube, cover plate and last sealing gasket are removed, the Rose Box that at last outer wall is welded with filter screen takes out, can clear up the work of impurity in the Rose Box subsequently, thereby finally reach the purpose of cleaning fuel tank, this kind structure can bleed off the oil in the fuel tank, can clear up the entrained impurity of oil return.In addition the utility model also have simple in structure, cost is low and can satisfy the advantage that multiloop is concentrated oil return simultaneously.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Number in the figure is respectively: 1-flange-type return tube; 2-pipe joint formula return tube; 3-fuel tank; 4-cover plate; 5-upward sealing gaskets; 6-lower seal pad; 7-cushion block; 8-Rose Box; 9-filter screen.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the mouth of fuel tank 3 is held the ring-type cushion block 7 that has been welded, on cushion block, be lined with lower seal pad 6, Rose Box 8 is installed on the lower seal pad, in the Rose Box upper end-hole sealing gasket 5 is housed, cover plate 4 is housed on last sealing gasket, after passing cover plate 4, go up sealing gasket 5, Rose Box 8 and lower seal pad 6 with screw, it is packed on the cushion block 7, there is closed bottom the lower end of Rose Box, its side face is fixed with filter screen 9, is separately installed with flange-type return tube 1 and pipe joint formula return tube 2 that power system is concentrated oil return on the cover plate 4.
Specific operation flow process of the present utility model is: multiloop oil refluxes simultaneously, the oil that refluxes is by each return tube, enter in the Rose Box, filtration through filter screen is got back in the fuel tank, impurity is owing to the filter efficacy of filter screen is stayed in the Rose Box, hydraulic press oil cylinder back warp is crossed each operation element circuit oil and is filtered fully the most at last, avoids oil pump to suck sump oil once more.
