Abstract
A filtering device with an oil-water separation function comprises a crude filter, an oil pump, a first valve, a primary filter, and a secondary filter which are orderly serially connected in a main oil path; a heater is disposed between the oil pump and the first valve; an oil-water separator and a check valve are orderly serially connected between the first valve and the primary filter; a pipeline with a second valve is in parallel connection with two ends of both the first valve and the check valve on the main oil path. The beneficial effects comprise: 1. energy saving and high efficiency; 2. safety and reliability; 3. capability of simultaneous application of the oil-water separator for removing water and the filters for removing solid impurities, or individual application of the impurity filters.
Description
Technical field
This invention relates to a kind of filter, particularly a kind of filter with oil-water separating function.
Background technology
The Main Function of fluid is to be lubricated and to cool off in that equipment is in service, and its quality good or not is directly connected to reliability and the economy of equipment.Equipment can be sneaked into along with the increase of running time various moisture content and impurity in running, can make metal surface generation corrosion in various degree with long-term the contact with metal parts of the oil of water, and generation corrosion thing, add the metal impurities that component abrasion produces in the running, oil lubrication and cooling effect are reduced, thereby can cause damage to the operation parts, even cause the generation of story, therefore need to filter and purify fluid.But filter plant is two kinds of different equipment with cleaning equipment, and the client often need to install two kinds of equipment simultaneously.But owing to the frequency of cleaning equipment use is not high, it is just passable only to need regularly unlatching that the moisture content in the fluid is purified removal.The filter plant that part band oil-water separating function is also arranged at present, but this kind equipment oil water separator when filtering also work simultaneously, can't control separately oil water separator, therefore can cause the waste of the energy.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of efficient energy-saving, safe and reliable, can shield the filter with oil-water separating function that oil water separator uses separately device for filtering impurities not needing the moisture content in the fluid purified when removing.
Technical scheme: a kind of filter with oil-water separating function, comprise the coarse filter, oil pump, the first valve, grade one filter and the secondary filter that are serially connected in successively in the working connection, be provided with heater between described oil pump and the first valve, be serially connected with successively oil water separator and check-valves between described the first valve and the grade one filter, the first valve and the parallel connection of check-valves two ends are with the pipeline of the second valve on the described working connection.When hydraulic system had not only needed to filter the impurity in the fluid but also had removed moisture content in the fluid, open the first valve, close the second valve, fluid enters oil water separator through coarse filter, oil pump, heater, the first valve, and the fluid of processing through oil water separator flows back to hydraulic system by check-valves, grade one filter and secondary filter again.When hydraulic system only need to be filtered impurity in the fluid, close the first valve, open the second valve, fluid flows back to hydraulic system through coarse filter, oil pump, heater, the second valve, grade one filter and secondary filter.The client can determine whether to open oil water separator as required.
The pipeline that described oil water separator bottom is provided with the 3rd valve is connected between described coarse filter and the oil pump.The 3rd valve is only just opened when oil water separator is keeped in repair, the 3rd valve is in closed condition at ordinary times, when needs keep in repair oil water separator, open the 3rd valve and the second valve, close the first valve, the fluid in the oil water separator flows back to hydraulic system through the 3rd valve, oil pump, heater, the second valve, grade one filter and secondary filter.Avoid the waste of oil water separator inner fluid when oil water separator is keeped in repair, make pure fluid again flow back to hydraulic system.
Described oil water separator be arranged in parallel alarm protecting apparatus into and out of oil port.When the hypertonia in the oil water separator, protective device action is so that part fluid is by described alarm protecting apparatus toward check valve and send alarm signal.Avoid oil water separator because hypertonia causes damage, improved security reliability.
Be respectively equipped with pressure warning unit on described grade one filter and the secondary filter.When the filter inner filter core stopped up, the pressure in the filter raise, and pressure is elevated to certain value alarm device and sends alarm signal, the reminding user to replace filter core.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: 1, efficient energy-saving; 2, safe and reliable; 3, not only can remove simultaneously the oily-water seperating equipment of moisture content and remove the solid impurity filter but also can use separately contaminant filter.
Description of drawings
Fig. 1 is control principle drawing of the present invention
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of filter with oil-water separating function, comprise the coarse filter 1, oil pump 2, the first valve 3, grade one filter 4 and the secondary filter 5 that are serially connected in successively in the working connection, be provided with heater 6 between described oil pump 2 and the first valve 3, be serially connected with successively oil water separator 7 and check-valves 8 between described the first valve 3 and the grade one filter 4, the first valve 3 and check-valves 8 two ends parallel connections are with the pipeline of the second valve 9 on the described working connection.When hydraulic system had not only needed to filter the impurity in the fluid but also had removed moisture content in the fluid, open the first valve 3, close the second valve 9, fluid enters oil water separator 7 through coarse filter 1, oil pump 2, heater 6, the first valve 3, and the fluid of processing through oil water separator 7 flows back to hydraulic system by check-valves 8, grade one filter 4 and cascade filtration 5 devices again.When hydraulic system only need to be filtered impurity in the fluid, close the first valve 3, open the second valve 9, fluid flows back to hydraulic system through coarse filter 1, oil pump 2, heater 6, the second valve 9, grade one filter 4 and secondary filter 5.The client can determine whether to open oil water separator 7 as required.
The pipeline that described oil water separator 7 bottoms are provided with the 3rd valve 10 is connected between described coarse filter 1 and the oil pump 2.The 3rd valve 10 is only just opened when oil water separator 7 is keeped in repair, the 3rd valve 10 is in closed condition at ordinary times, when needs keep in repair oil water separator 7, open the 3rd valve 10 and the second valve 9, close the first valve 3, the fluid in the oil water separator 7 flows back to hydraulic system through the 3rd valve 10, oil pump 2, heater 6, the second valve 9, grade one filter 4 and secondary filter 5.Avoid the waste of oil water separator 7 inner fluids to oil water separator 7 maintenance the time, make pure fluid again flow back to hydraulic system.
Described oil water separator 7 be arranged in parallel alarm protecting apparatus 11 into and out of oil port.When the hypertonia in the oil water separator 7, protective device action is so that part fluid is by described alarm protecting apparatus 11 toward check valve 8 and send alarm signal.Avoid oil water separator 7 because hypertonia causes damage, improved security reliability.
Be respectively equipped with pressure warning unit 12 on described grade one filter 4 and the secondary filter 5.When the filter inner filter core stopped up, the pressure in the filter raise, and pressure is elevated to certain value alarm device 12 and sends alarm signal, the reminding user to replace filter core.
