Description
Technical Field
The utility model relates to the technical field of hydraulic oil filtration, in particular to an independently-operated oil purifying and recycling device.
Background
At present, a filter designed for a hydraulic system of a thermal power plant is arranged at an inlet of an oil pump, a filter shell is not arranged, and long-term soaking is carried out in oil. The filter element immersed in the oil is directly polluted by the hydraulic oil, and the oil pipe and the oil tank cover are required to be removed during replacement, so that the replacement is inconvenient. Because the oil product problem has caused many times solenoid valve jam, causes hydraulic system trouble, can't normally start and stop the circulating pump, causes serious threat to power generation facility's reliability and economic nature. If a movable oil filter is adopted, secondary pollution can be generated. Since the inlet and outlet pipe is exposed to the air, it is easily affected by dust and peripheral impurities. In addition, other parameters of the oil products of each hydraulic station are different, and cross contamination is easy to generate.
Disclosure of Invention
According to the technical problem set forth above, an oil purifying and recycling device capable of being operated independently is provided. The utility model adopts the following technical means:
the utility model provides an oil purification and recirculation device that can independently operate, includes hydraulic oil pump bypass recirculation filter equipment, hydraulic oil pump bypass recirculation filter equipment installs the pressurize control main line behind the hydraulic oil pump export check valve, including tee bend, filtration pipeline, valve and filter, and tee bend's one end links to each other with filtration pipeline, and on the other both ends link to each other, be provided with valve and filter on the filtration pipeline, the output of filtration pipeline is connected in the oil tank.
Further, the valve is a stop valve.
Further, the filter is a high pressure filter.
Further, the specification of the filter element of the high-pressure filter is 5 μm.
The utility model changes the pipeline into the operation mode of the switching hydraulic station or the oil filtering mode by switching the valve, and the utility model externally arranges the filter on the oil tank, thereby being convenient for replacement, replacing filter cores with different precision according to different hydraulic oil, being convenient for cleaning, not needing to be connected with other oil filtering devices, and avoiding secondary pollution.
Drawings
In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, and it is obvious that the drawings in the following description are some embodiments of the present utility model, and other drawings may be obtained according to the drawings without inventive effort to a person skilled in the art.
Fig. 1 is a system diagram of the present utility model after the hydraulic oil system is accessed.
In the figure: 1. a tee joint; 2. a filter pipeline; 3. a stop valve; 4. a high pressure filter; 5. and an outlet of the filtering pipeline.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the embodiment of the utility model discloses an independently-operable oil product purifying and recycling device, which comprises a hydraulic oil pump bypass recycling filter device, wherein the hydraulic oil pump bypass recycling filter device is arranged on a pressure maintaining control main pipeline behind a hydraulic oil pump outlet one-way valve and comprises a welded tee joint 1, a filter pipeline 2, a valve 3 and a filter 4, one end of the tee joint is connected with the filter pipeline, the other ends of the tee joint are connected with the filter pipeline, the filter pipeline is provided with the valve and the filter, and an output end 5 of the filter pipeline is connected in an oil tank.
Further, the valve is a stop valve.
Further, the filter is a high pressure filter.
Further, compared with the prior art, the hydraulic station operation mode and the oil filtering mode can be switched at any time, the high-pressure filter can adopt a 5 mu m filter core with higher precision to thoroughly filter impurities contained in hydraulic oil, the filter screen can be conveniently removed, and overhaul procedures are reduced. In the overhaul process, the complex process that the filter element is taken out by disassembling the oil tank by utilizing the lifting appliance after the condition of the filter screen can be observed only through the observation window in the prior art is avoided.
As a practical application mode, the hydraulic oil of the automatic pressure maintaining system flows back to the oil tank after entering the filter, when the main system detects that the pressure is reduced, the pump is automatically started and stopped to stabilize the pressure, so that a closed automatic circulation is formed, and the quality of the hydraulic oil is ensured at any time by realizing the real-time filtration of the oil in a simplest mode under the condition that other oil filtering devices are not required to be connected and control logic is not required to be changed.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
