Abstract
The invention discloses a device for automatically cleaning an oil filter. The device is developed aiming at the defects that a filter element of the conventional oil filter for a concrete pump hydraulic system is easy to block and is replaced frequently. Most of impurity particles are adsorbed to the surface of the filter element, so the overflowing area of the filter element is blocked, the pressure consumption is increased, and the performance and the service life of a host machine are seriously reduced. After the host machine stops operating every time, the device for automatically cleaning the oil filter can automatically start an electromagnet to drive the filter element to vibrate at high frequency and low amplitude to ensure that most of large impurity particles which are adhered to the surface of the filter element fall down and are deposited at the bottom of an oil tank, namely the filter element is cleaned once; and when the filter element works again, high oil filtering capacity and small pressure loss are kept. Under the condition of the same filtering accuracy, the oil passing capacity of the oil filter can be greatly improved and the service life can be prolonged greatly; and under the condition of the same service life, several levels of the filtering accuracy of the filter element can be improved. The performance reliability and the service life of all components in a hydraulic oil pump and a system can be guaranteed.
Description
One, technical field:
The present invention relates to automatic flushing device and the method for a kind of machinery hydraulic system with oil purifier.Be particularly useful for adopting higher working pressure hydraulic system and the less mobile unit of reservoir capacity to use oil purifier.Also be applicable to all kinds of oil purifiers of other all kinds of working pressure hydraulic systems.
Two, the state of the art:
Modern project machinery and various jumboes have adopted Hydraulic Power Transmission System widely.In all kinds of Hydraulic Power Transmission Systems for the reliable performance and working life of the various hydraulic element in the protective system effectively; Mostly be provided with filter and come in the filtering oil tank liquid neutralizer pressing system because of the motion wearing and tearing of each element and possibly hide the various impurity particles in each element, guarantee the turbidity test of system's inner fluid at the filler opening of hydraulic system and return opening.
At present, the oil strain mode in the existing machinery equipment hydraulic system all is to force the flow through slit of filter core of fluid to reach the impurity particle of filtering greater than gap size.Though the filter type of this single-stage filter core can guarantee filtering traffic and the filter core precision corresponding turbidity test of system to fluid at the use initial stage; But prolongation along with service time; Various impurity particles not of uniform size can promptly stick to the surface of filter core in the fluid; Stop up the area of passage of filter core, made it cross oily ability and greatly reduce, increased pressure loss.This situation develops into certain degree, will force the user to shut down more renew cartridge to the oil suction oil purifier, otherwise can cause the oil pump oil suction not enough, produces cavitation erosion and damages oil pump.More serious is if system's oil suction is not enough, can destroy the working stability of system, causes the generation of accident.To the oil return oil purifier is exactly that return pressure increases, and has increased the energy consumption and the temperature rise of system; If have the oil return oil purifier of bypass pressure limiting one-way valve, will directly open one-way valve and flow back to fuel tank, oil purifier lost efficacy and took back fuel tank to the former partial impurities that leaches again, added systemic circulation again.People cause it to cross oily ability drop for the easy obstruction of alleviating the oil suction oil purifier; And then the active duty cycle of assurance main frame; Have to select to reduce the oil suction filter core of filter precision grade; Make thicker particle inspiration system like this, quickened the wearing and tearing of each class component and Sealing in oil pump and the system, make system in let out and the decline of the increase, volumetric efficiency decline and the working pressure that leak.On the oil return oil purifier because the pressure reduction that allows strengthens and for filtering appts in more impurity, the turbidity test that make system's inner fluid have generally selected the filter precision several times to be higher than the oil return filter core of oil suction filter core near actual demand.In order to reduce energy consumption and the heating that reduces system; Often select the oil return bypass one-way valve of low cracking pressure, because the filter precision grade of oil return filter core is higher, filter core stops up faster than the oil suction filter core; The pressure loss of the oily filter core of flowing through strengthens; Its result is exactly: or renew cartridge more continually, or the oil return bypass one-way valve of leaving is opened, the actual failure state that is in of oil return oil purifier.This situation shows typical case on concrete pump.
Three, goal of the invention and solution:
The object of the invention is exactly the automatic flushing device to the easy a kind of fuel filter element that stops up and designed oily ability endurance weak point and research and develop of existing single-stage oil suction filter core.Because big portion impurity particle all is the surface that is adsorbed on filter core; After the every operation of main frame stopped, pressure reduction sorrowful inside and outside the filter core disappeared, and at this moment forces the filter core high frequency to shake by a narrow margin; Former bigger impurity particle attached to cartridge surface is come off be deposited on fuel tank bottom or oil purifier cylindrical shell bottom; Be equivalent to filter core has been done once to clean, when filter core is worked once more, just can keep the higher oil strain ability and the less pressure loss.
Solution of the present invention is: the oil suction oil purifier of band automatic flushing device is by electromagnet 1, upper end cap 2, inner cover plate 3, cylindrical shell 4, filter core 5,6 groups of rubber pads and forming down.Start oil pump, fluid sucks from the lower openings of cylindrical shell 4, after the filtration of filter core 5, flows to the cavity volume in garden in cylindrical and the cylindrical shell 4 of filter core 5, is inhaled into oil pump then.Impurity particle in the fluid is leached by filter core 5 and attaches suction within it on the surface.After the each operation of main frame stops, playing motor magnet 1 automatically, force the filter core high frequency to shake 1-2 minute by a narrow margin, former impurity particle attached to cartridge surface is come off, and deposit to the fuel tank bottom, all filter core has been done once to clean after the operation quite each time.
Oil purifier automatic flushing device of the present invention and existing no cleaning and filtering compared with techniques; Because after the each operation of main frame stops; Most of impurity particle attached to cartridge surface is removed in the capital automatically, when filter core is worked once more, keeps the higher oil strain ability and the less pressure loss.Identical filter precision grade condition can be bigger the oil filling capacity and working life of raising oil suction filter; Under the condition in identical working life, can improve the several class of filter precision grade of filter core, for the turbidity test of the working medium of host hydraulic system provide support, for the reliable performance and the prolongation in working life of main frame and its all elements provides guarantee.
Four, description of drawings:
Accompanying drawing 1 is a structural drawing of the present invention.
Five, mode of execution:
Embodiment of the present invention is: when starting oil pump, the fluid in the fuel tank sucks the inner chamber of filter core 5 from the lower openings of cylindrical shell 4, after the filtration of filter core 5, flows to the cavity volume between the garden in cylindrical and the cylindrical shell 4 of filter core 5, is inhaled into oil pump then.Impurity particle in the fluid is leached by filter core 5 and attaches suction on the phase internal surface.After the each operation of main frame stops; Automatically play motor magnet 1, force the filter core high frequency to shake 1-2 minute by a narrow margin, the most larger particles of former impurity particle attached to cartridge surface is come off; And deposit to the fuel tank bottom, all filter core has been done once to clean after the operation quite each time.
