Abstract
The invention relates to a filtering device of a hydraulic oil pump vehicle, comprising an oil tank, an oil pump generating set, an oil returning filter, a first stage oil filter and a second stage oil filter, wherein the oil tank, the oil returning filter, the oil pump generating set, the first stage oil filter and the second stage oil filter are successively connected through oil pipes; the filtering precision of the oil returning filter is greater than the filtering precision of the first stage oil filter; and the filtering precision of the first stage oil filter is greater than the filtering precision of the second stage oil filter. Compared with the prior art, the filtering device of the hydraulic oil pump vehicle has the advantages of simple structure, easiness in connection, cost saving and the like.
Description
Technical field
The present invention relates to filtrating equipment, especially relate to a kind of filtrating equipment of hydraulic oil pump tender.
Background technique
YBC-3A type hydraulic oil pump tender is the inspection that is used for K8 type plane hydraulic system working state.When K8 type plane hydraulic system flight-line service and regular working inspection, this car can provide and satisfy the required pressure of usage requirement, flow, its outlet pressure, and flow can adjust setting as required.This hydrant cart has the self-cleaning function, utilizes to provide fuel tank for oneself and can finish cleaning to K8 type plane hydraulic system.And have a following function:
A. provide the hydraulic oil source that is not less than seven grades of NAS1638, to guarantee the turbidity test of K8 type plane hydraulic system;
B. to K8 type plane hydraulic system each several part, as the functional check of folding and unfoldings such as undercarriage, wing flap, airbrake action situation;
C. to K8 type plane hydraulic system each several part, as folding and unfolding times such as undercarriage, wing flap, airbrakes, service behaviour is done quantitative check;
D. K8 type plane hydraulic system is done circulating cleaning, reach technical specifications regulation grade (eight grades of GJB420-878/A level or NAS1638) with the dustiness that guarantees JL8 type plane hydraulic system.
For guaranteeing the normal stable operation of airplane operation system, the turbidity test of plane hydraulic system just must reach certain standard, if can not be up to standard, just can not guarantee the proper functioning of each annex, and the possibility of result is catastrophic.
Original hydraulic pressure car uses the filter of single highi degree of accuracy oil, and the efficient of filtration is undesirable, and time half a day of will working usually just can be finished Cleaning of hydraulic system work, and the filter core of the oil filter in two months of working will dirtyly stop up.More renew cartridge just can work on.Have a strong impact on the process of line service, be difficult to guarantee the rate of attendance of aircraft.If adopt the hydraulic pressure car of full import, not only cost an arm and a leg, and have the system matches problem.
Summary of the invention
Purpose of the present invention is exactly the filtrating equipment that a kind of simple in structure, hydraulic oil pump tender of being easy to safeguard is provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of filtrating equipment of hydraulic oil pump tender, this device comprises fuel tank, Oil pump electrical machinery group, it is characterized in that also comprise oil return filter, the filter of first order oil, second level oil filter, described fuel tank, oil return filter, Oil pump electrical machinery group, the filter of first order oil, second level oil filter connect by oil pipe successively.
The filter precision of described oil return filter is greater than the filter precision of first order oil filter.
The filter precision of described first order oil filter is greater than the filter precision of second level oil filter.
The filter precision of described oil return filter is 12 microns.
The filter precision of described first order oil filter is 10 microns.
The filter precision of described second level oil filter is 3 microns.
Described oil return filter, the filter of first order oil, second level oil filter are the aviation filter.
Compared with prior art, the present invention has the following advantages:
1, simple in structure, be easy to connect: oil return filter, the filter of first order oil, second level oil filter are aviation filter, interface standard unanimity, stable work in work.
2, significantly improve working efficiency, general work can satisfy system's turbidity test requirement half an hour.
3, save cost, more the time of renew cartridge by original per two months once, extend to every two years once.
Description of drawings
Fig. 1 is the structural representation of the filtrating equipment of a kind of hydraulic oil pump tender of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, a kind of filtrating equipment of hydraulic oil pump tender, this filtrating equipment comprises oil return filter 4, first order oil filter 2, second level oil filter 3, the filter precision of described oil return filter 4 is 12 microns, flow is handled continuously greatly, the filter precision of described first order oil filter 2 is 10 microns, and the filter precision of described second level oil filter 3 is 3 microns.
Earlier by oil return filter 4, filter precision is 12 microns to fluid in system, and contamination capacity is big; Flow is handled continuously greatly, can in advance large particle in the fluid of being returned by plane hydraulic system be filtered out, and in the time of the protection oil pump, also can reduce later stage filtration duty pressure.
Filter 2 through first order oil earlier through the fluid that Oil pump electrical machinery group 1 is come out, the filter precision of first order oil filter 2 is 10 microns, as elementary smart filter, can filter out most of particle, and contamination capacity is big, is not easy dirty obstruction.
Fluid enters second level oil filter 3 more earlier through first order oil filter 2, and second level oil filter 3 is the filter of highi degree of accuracy oil, and precision is 3 microns, reaches design objective to guarantee oil cleanliness.Because oil return filter 4 and first order oil filter 2 filter out most of large particle pollutant, second level oil filter 3 also is not easy dirty obstruction, has so both guaranteed the turbidity test requirement to extend working time again.
