Abstract
A hydraulic jack base with filters comprises a base body. The upper end face of the base body is provided with a working oil cavity bottom face and an oil storage cavity bottom face. The working oil cavity bottom face is provided with oil inlet holes and oil discharge holes, and the oil storage cavity bottom face is provided with oil return holes and oil outlet holes. The base is internally provided with oil inlet channels used for enabling the oil outlet holes to communicate with the oil inlet holes, and oil discharge channels used for enabling the oil discharge holes to communicate with the oil return holes. The hydraulic jack base further comprises the filters which are connected into the oil outlet holes and used for filtering impurities in oil. The hydraulic jack base has the advantages that after the hydraulic jack base is applied to a hydraulic jack, the oil entering an working oil cavity from an oil storage cavity needs to pass through the filters, the impurities in the oil are adsorbed to filter nets, the problem that the one-way valve cannot normally work due to the fact that the impurities in the oil stick to the sealing face of a one-way valve base is effectively solved, and accordingly normal working of the jack is ensured.
Description
Technical field
The present invention relates to jack stand, particularly a kind of jack stand with filter.
Background technology
Hydraulic jack is the jacking apparatus commonly used in industrial production, its internal working oil chamber is connected with shoe cream room by the asphalt channel of chassis interior, after the fluid in working oil chamber enters shoe cream room, piston component falls, realize off-load, after the fluid of shoe cream room enters working oil chamber, by piston component jacking, so as to jacking weight.The oil-in connected with outside oil pump is additionally provided with base in working oil chamber, oil-in is connected by the asphalt channel of chassis interior with shoe cream room, and ball type check valve is provided with asphalt channel, and check valve is fitted by steel ball and sealing surface of seat and forms sealing.If being stained with impurity on sealing surface of seat, the normal sealing of check valve will be affected.But pumped into by oil pump from shoe cream room and usually can contain in the fluid in working oil chamber impurity, after a period of time, impurity can be bonded on the sealing surface of one-way valve seat unavoidably, cause check valve cisco unity malfunction.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, and provides a kind of jack stand with filter.After it solves existing hydraulic jack using a period of time, impurity is bonded on sealing surface of seat, causes the problem of check valve cisco unity malfunction.
The technical scheme is that：Jack stand with filter, including pedestal；
Pedestal upper surface is provided with working oil chamber bottom surface and shoe cream room bottom surface, working oil chamber bottom surface is provided with fuel feed hole and oil leak hole, shoe cream room bottom surface is provided with spill port and oil outlet, chassis interior is provided with the oil inlet passage for connecting oil outlet and fuel feed hole, and for connecting the drain path of oil leak hole and spill port；
Its also include be connected in oil outlet, for filtering fluid in impurity filter.
Further technical scheme is the present invention:The hole wall of oil outlet is provided with internal thread, filter includes shell and the screen pack being located in shell inner cavity, shell lower end is provided with externally threaded connector, connector is communicated with shell inner cavity, the oil through communicated with shell inner cavity is provided with side wall of outer shell, shell is arranged in oil outlet by the external screw thread on connector.
Further technical scheme is the present invention:The lower end of oil through is h with the distance of enclosure bottom, and h is 1～2.5mm.
Further technical scheme of the invention is：H is 2mm.
The present invention has the advantage that compared with prior art：
After applying in hydraulic jack, filter is must pass through from shoe cream room into the fluid of working oil chamber, impurity in fluid is attracted on screen pack, efficiently solve the impurity in fluid to be bonded on the sealing surface of one-way valve seat, cause the problem of check valve cisco unity malfunction, so as to ensure that the normal work of jack.
Below in conjunction with figure, the invention will be further described with embodiment.
