Description
Technical field
The present invention relates to the lubrication system of high-pressure oil pump of engine, be specifically related to the filtrating equipment of the lubrication system of high-pressure oil pump of engine.
Background technique
The high-pressure fuel pump of motor is oil-fired system " heart ", its effect is continuously engine fuel injector to provide high pressure fuel, motor in the running, in its high pressure oil pump, the driving cam of High Rotation Speed drives oil pump tappet and does high speed to-and-fro motion, and the contact stress between driving cam and oil pump tappet is large, serious wear.Therefore effectively lubricating and cooling must be carried out to this mechanism, and in available engine high pressure oil pump, itself there is no the structure of filtering extreme pressure lubricant impurity, be easy to make in-engine metal impurities etc. enter in the friction pair of high pressure oil pump driving mechanism with extreme pressure lubricant, cause inordinate wear and the inefficacy of surface of friction pair, engine noise and mechanical loss is caused to increase, thus affect whole aircraft reliability, the complaint degree of adding users.
Summary of the invention
Structure of the present invention provides a kind of filtrating equipment of lubricating oil way of high-pressure oil pump, this apparatus structure is simple, cost is low, be convenient to maintenance, dismounting and cleaning, can stop that the metal impurities being greater than specified diameter enter in high pressure oil pump driving mechanism friction pair, avoid the inordinate wear of high pressure oil pump driving mechanism, reduce the noise of motion and extend the working life of high pressure oil pump.
The filtrating equipment of a kind of lubricating oil way of high-pressure oil pump of the present invention, comprise high pressure oil pump, the oil leab being communicated with high pressure oil pump actuator chamber and oil cylinder head way is provided with in high pressure oil pump, in described oil leab, blind hole bolt is installed, the oil inlet hole being communicated with blind hole and oil leab entry end is had at the screw rod waist of blind hole bolt, this oil inlet hole is built with filter screen, and the blind hole of blind hole bolt is communicated with oil inlet hole and high pressure oil pump actuator chamber, is formed and is communicated with oil duct;
Extreme pressure lubricant flows into oil leab from oil cylinder head way, and by entering connection oil duct after filter screen filtration, finally enters high pressure oil pump actuator chamber, the extreme pressure lubricant entering high pressure oil pump actuator chamber is played to the effect of filtration.
Further, described oil inlet hole is radial direction through hole, is provided with step at orifice position, and described filter screen is by welding or be bondingly arranged on step surface.
Described step is totally two rank, and outside diameter is greater than inside diameter, and described filter screen welds or is bonded on the step surface of outside.
Due to the difference of engine operation condition; lubricating oil pressure in oil leab produces fluctuation with operating mode; filter screen can produce vibration along with pressure, and the design of inner side step can effectively avoid filter screen to contact with the frequent of blind hole bolt, and protection filter screen is not by inordinate wear or produce noise.
Described blind hole bolt head and high pressure oil pump joint are provided with seal ring, good airproof performance.
Described blind hole bolt is removably fixed in oil leab by binding thread, and at the aperture place of oil leab, the position that blind hole bolt head is combined with aperture is provided with seal ring, good airproof performance.
During work, the oil leab that first extreme pressure lubricant in oil cylinder head way enters high pressure oil pump arrives metal screen place, is being tackled by the contaminant filter in lubricant oil through metal screen, enters in high pressure oil pump actuator chamber by being communicated with oil duct.
The present invention compared with prior art has the following advantages:
1, can stop that the metal impurities being greater than specified diameter enter in high pressure oil pump driving mechanism friction pair, efficiently avoid the inordinate wear of high pressure oil pump driving mechanism, reduce the noise of motion and extend the working life of high pressure oil pump, also ensure that the effectively lubricating of high pressure oil pump driving mechanism simultaneously;
2, blind hole bolt cleaning impurity can be pulled down in complete machine outside like a cork, whole high pressure oil pump driving mechanism need not be dismantled, make maintenance, dismounting, cleaning, assembling all very simple, and can reuse;
3, structure is simple, and cost is low.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The filtrating equipment of lubricating oil way of high-pressure oil pump as depicted in figs. 1 and 2, comprise high pressure oil pump 1, blind hole bolt 2 and filter screen 4, in high pressure oil pump 1, be provided with the oil leab 3 being communicated with high pressure oil pump actuator chamber and oil cylinder head way 6, blind hole bolt 2 is removably mounted in oil leab 3 by binding thread.The oil inlet hole 2-1 be communicated with oil leab 3 entry end is had at the screw rod waist of blind hole bolt 2, this oil inlet hole 2-1 is radial direction through hole, step 2-2 is had at the two ends of radial direction through hole, step 2-2 is totally two rank, step 2-2 outside diameter is greater than inside diameter, filter screen 4 is by welding or be bondingly arranged on the step surface of outside, and in the screw rod of blind hole bolt 2, have the connection oil duct 2-3 extended vertically, oil inlet hole 2-1 is communicated with high pressure oil pump actuator chamber by this connection oil duct 2-3.Seal ring 5 is provided with at blind hole bolt 2 head and high pressure oil pump 1 joint.
During work, first extreme pressure lubricant in oil cylinder head way 6 enters in the oil leab 3 of high pressure oil pump 1, then filter screen 4 place is arrived, filter screen 4 is by the contaminant filter interception (guaranteeing that the lubricant oil after filtering can meet the requirement that driving mechanism friction pair specifies completely) in extreme pressure lubricant, enter in high pressure oil pump 1 actuator chamber finally by after connection oil duct 2-3, avoid the inordinate wear that high pressure oil pump driving mechanism causes because of the impurity in lubricant oil.Motor can be pulled down this blind hole bolt 2 easily when maintaining and clean impurity in outside, need not dismantle whole high pressure oil pump driving mechanism.Adopt the cleansing medium of specifying to clean filter screen 4, put in back blind hole bolt 2 after cleaning up, reach reusable object, reduce motion noise so to greatest extent and extend high pressure oil pump 1 working life.
Blind hole bolt 2 screw rod has the binding thread of specifying specification, be arranged on high pressure oil pump 1 body with the torsion of regulation, head and high pressure oil pump 1 joint of blind hole bolt 2 are provided with seal ring 5, ensure that impurity cannot enter the oil duct after filtration by non-screen area.
