Abstract
The invention relates to a hydraulic machine with irregularly-shaped filtering screens. The hydraulic machine comprises an oil tank, a stamping unit is arranged nearby the oil tank, an oil return tube is arranged between the oil tank and the stamping unit, and a filtering cylinder is arranged between the oil return tube and the oil tank and provided with a cylinder body. The upper end of the cylinder body is connected with the oil return tube, an oil outlet connected with the oil tank is arranged at the lower end of the cylinder body, and two filtering screens with middle cambered protrusions are arranged in the middle of the cylinder body. According to the hydraulic machine, the filtering cylinder with the filtering screens are arranged between the oil return tube and the oil tank, hydraulic oil with certain pressure is filtered through the filtering screens, and accordingly, impurities are filtered, and impurities might causing damage to hydraulic element are isolated; the structure is simple, and the filtering unit maintenance can be achieved conveniently by changing the filtering screens frequently.
Description
Technical field
The present invention relates to mechanical field, especially a kind of hydraulic press of special-shaped screen pack.
Background technology
Hydraulic press chief component is hydraulic system; and hydraulic oil wherein is often mixed with impurity; as airborne dust, oxide skin, iron filings, metal dust, encapsulant fragment, paint skin and yarn fiber etc.; these impurity are the major reasons that cause Hydraulic Elements fault, have had a strong impact on reliability and the service life of hydraulic system.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the problem of above-mentioned middle existence, provide a kind of hydraulic press of special-shaped screen pack.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hydraulic press of special-shaped screen pack, comprise fuel tank, side at described fuel tank is provided with decompressor, between described fuel tank and decompressor, be provided with oil return pipe, between described oil return pipe and fuel tank, be provided with cartridge filter, described cartridge filter has cylindrical shell, the upper end of described cylindrical shell is connected with oil return pipe, in the lower end of described cylindrical shell, be provided with the oil-out being connected with fuel tank, in the middle of being provided with, there are two screen packs with middle circle arc convex in described cylindrical shell.
The invention has the beneficial effects as follows: the hydraulic press of described a kind of special-shaped screen pack, by being provided with the cartridge filter of screen pack between the oil return pipe at hydraulic press recovery hydraulic oil and fuel tank, filtration by the hydraulic oil with certain pressure through screen pack, to reach the object of impurity screening, the impurities that may cause Hydraulic Elements to damage comes, this programme is simple in structure, can realize easily the maintaining of filter by frequent replacing screen pack.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the overall structure schematic diagram of the hydraulic press of a kind of special-shaped screen pack of the present invention;
Fig. 2 is the structural representation of cartridge filter in Fig. 1.
Accompanying drawing acceptance of the bid note is described below: 1, fuel tank, 2, oil return pipe, 3, decompressor, 4, cartridge filter, 4-1, cylindrical shell, 4-2, oil-out, 4-3, screen pack.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
The hydraulic press of a kind of special-shaped screen pack as depicted in figs. 1 and 2, there is fuel tank 1, side at described fuel tank 1 is provided with decompressor 3, between described fuel tank 1 and decompressor 3, be provided with oil return pipe 2, between described oil return pipe 2 and fuel tank 1, be provided with cartridge filter 4, described cartridge filter 4 has cylindrical shell 4-1, the upper end of described cylindrical shell 4-1 is connected with oil return pipe 2, at described cylindrical shell 4-1) lower end be provided with the oil-out 4-2 being connected with fuel tank 1, in described cylindrical shell 4-1, be provided with two screen pack 4-3 with middle circle arc convex.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
