The device can be used to simply monitor the pollution of the hydraulic oil regularly or irregularly as required and evaluate the pollution degree (mild, moderate and severe pollution degree) of the oil liquid; and then whether a filter element is to be replaced can be determined and the polluted oil liquid can be filtered and cleaned to realize the re-utilization of the oil liquid.
Description
Technical field
The utility model relates to a kind of monitoring oil contamination and filters washing unit, particularly a kind of hydraulic power system monitoring oil contamination and cleaning and filtering device.
Background technique
In modern hydraulic equipment, the pollution of fluid is controlled and is recycled extremely important.The fault that hydraulic equipment causes owing to oil contamination accounts for more than 80% of total failare, many factory and enterprises or unit in charge of construction do not carry out contamination monitoring to the employed fluid of hydraulic equipment, and this makes contaminated fluid have a strong impact on the usability and the life-span of each hydraulic element in the system.And the factory and enterprise hydraulic oil or the fluid that behind certain hour, will more renew employed fluid, used fluid is done discarded the processing, cause waste and environmental pollution, strengthened the factory and enterprise cost of production.Therefore, under the prerequisite that guarantees the hydraulic equipment functional reliability, how to control oil contamination, and fluid is fully utilized, will become and reduce the oil contamination infringement, improve the key issue of hydraulic element working life and assurance hydraulic system maximum utility.Hydraulic oil pollution monitoring and filter cleaning are that modern hydraulic systems acquisition best effort effect is taked necessary technical measures.,, all be crucial still no matter from the angle of economic benefit from the angle of academic significance and technical meaning.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of hydraulic power system monitoring oil contamination and cleaning and filtering device are provided, this device can be easily on request regularly or irregularly flexibly monitor the pollution of hydraulic oil, and the contaminated degree of judgement fluid (slight, moderate and serious), decision renew cartridge whether more then, contaminated fluid is carried out filter cleaning, realize that fluid utilizes again.
For solving the problems of the technologies described above, the utility model is achieved in that it comprises hydraulic system working connection (A), it is characterized in that: described hydraulic system working connection (A) is gone up an oil circuit (B) is set, and oil contamination indicating device (3) and filter (2) are set on described the oil circuit (B); Described oil contamination indicating device (3) and filter (2) are connected in parallel, and described filter (2) is used for the filtration and the cleaning of fluid, and described oil contamination indicating device (3) is connected in parallel with described filter (2).
Solenoid directional control valve (5) is set on the described hydraulic system working connection (A).
Solenoid directional control valve (4) is set on described the oil circuit (B).
Described differential oil contamination indicating device (3) comprises differential pressure pickup and simple pointer differential pressure indicator, and described differential pressure pickup is used to measure the pressure difference signal at filter (2) two ends, and the signal that records is exported by the simple pointer differential pressure indicator.
Described oil circuit (B) gone up series connection one-way valve (1) is set.
Described solenoid directional control valve (5) and solenoid directional control valve (4) are the bi-bit bi-pass solenoid directional control valve.
The beneficial effects of the utility model are:
The utility model can be monitored out the pollution level of fluid in the hydraulic work system process, can be behind renew cartridge more, contaminated fluid is cleaned filtration, realize that fluid utilizes again, can use the coherent detection instrument to pressure difference signal gather, function such as storage, when oil contamination transfinites, and can provide alarm signal, remind operator in time to clean or change fluid, take place with the prevention major accident, can also pass through simultaneously bi-bit bi-pass solenoid directional control valve (4), (5) control monitoring and clean time, guarantee the hydraulic system proper functioning.Compared with prior art, it makes that with the consideration of uniting of oil liquid monitoring and filtering technique oil contamination control is more effective; Each hydraulic element is installed on the integrated package, has optimized structure, process and install very convenient; This device partly is embedded in the hydraulic system, and oil hydraulic circuit and element when having reduced this device of independent design have reduced design and manufacture cost; Can detect pressure difference signal, for monitoring, diagnosis and the control of fluid provides convenience.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, bi-bit bi-pass solenoid directional control valve 5 is on the hydraulic system working connection, and bi-bit bi-pass solenoid directional control valve 4, filter 2 and one-way valve 1 partly are embedded in hydraulic circuit on an oil circuit of working connection, and these two oil circuits are to be connected in parallel; Differential oil contamination indicating device 3 is used for measuring the pressure difference signal at filter 2 two ends on the one hand, is used to refer to contaminated degree of hydraulic oil or output pressure difference signal on the other hand; Fluid was controlled by bi-bit bi-pass solenoid directional control valve 4,5 by the time of filter 2, and the function that can reach monitoring and filter by the different filter cores of changing in the filter 2.
First kind of working method: oil contamination state on_line monitoring: set the turn around time of switching at first for bi-bit bi-pass solenoid directional control valve 4,5, and power on for solenoid directional control valve 4,5 simultaneously, hydraulic system oil liquid flows to and switches to the oil liquid monitoring function, and fluid flows back to working connection through bi-bit bi-pass solenoid directional control valve 4, filter 2 and one-way valve 1.By observing the indicating area of simple pointer pressure reduction dial plate on the differential oil contamination indicating device 3, the degree of judging monitored oil contamination is slight, and moderate is still serious.Whether final decision cleans filtration to monitored fluid, still renew oil more.Then with 4, the 5 outage commutations of bi-bit bi-pass solenoid directional control valve, the utility model off-line.
Second kind of working method: fluid filters the cleaning state: at first according to the filter core of the suitable filter 2 of the described replacing of claim 7, setting bi-bit bi-pass solenoid directional control valve 4,5 switches on turn around time, power on for then bi-bit bi-pass solenoid directional control valve 4,5 simultaneously, the hydraulic power system fluid flow direction is switched to fluid filter washing function, fluid flows back to working connection through bi-bit bi-pass solenoid directional control valve 4, filter 2 and one-way valve 1.After solenoid directional control valve 4,5 outage commutations, expression is filtered fluid filtration cleaning and finishes at last, and fluid can continue to use, and hydraulic system is recovered proper functioning.
Above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many kind distortion can also be arranged, and for example changes the structural type of oil purifier and the method for measurement of pressure difference etc.
