Abstract
The invention discloses a hydraulic oil filtering system for an oil press. The system comprises an oil tank, a first return oil pipeline, a second return oil pipeline, a first filter, a second filter, a first valve, a second valve and an oil pump oil suction port, wherein an oil outlet of the oil tank is communicated with one end of each of the first and second return oil pipelines; the other ends of the first and second return oil pipelines are communicated with the oil pump oil suction port respectively; the first and second filters and the first and second valves are arranged on the first and second return oil pipelines respectively; the first and second return oil pipelines can be closed by the first and second valves respectively. According to the system, a double-loop filtering mode is adopted, and during maintenance or repair, one side can be closed through the corresponding valve, and the other side can normally work, so that influence on the work of the oil press is eliminated, and loss can be avoided.
Description
Technical field
The present invention relates to a kind of oil hydraulic press oil circuit, particularly a kind of oil hydraulic press hydraulic oil filtering system.
Background technique
The traditional oil circuit of hydraulic press is single loop filtration system, if filter damages or during regular maintenance, machine must stop, and can not move, and will dally over one's work, and causes damage.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of oil hydraulic press hydraulic oil filtering system, this oil hydraulic press does not delay machine and normally works when filter keeps in repair by hydraulic oil filtering system.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of oil hydraulic press hydraulic oil filtering system, comprise fuel tank, first and second oil returning tube, first and second filter, first and second valve and oil pump inlet port, the oil outlet of fuel tank is communicated with first and second oil returning tube one end respectively, first and second oil returning tube the other end is communicated with oil pump inlet port respectively, and on first and second oil returning tube, being respectively equipped with first and second filter respectively can be closed by first and second oil returning tube with first and second valve described in first and second valve.
As a further improvement on the present invention, described first and second valve is butterfly valve.
As a further improvement on the present invention, described first and second oil returning tube the other end is communicated with oil pump inlet port by Y-pipe.
Useful technique effect of the present invention is: the present invention, by adopting double loop to filter, can pass through valve closing one side when safeguarding or keeping in repair, and opposite side can normally be worked, and does not affect machine work, avoidable loss.
Accompanying drawing explanation
Fig. 1 is prior art principle schematic;
Fig. 2 is principle schematic of the present invention.
