Description
Technical field the utility model relates to the lubrication system of machinery or power equipment, particularly relates to a kind of lubricant oil that makes and takes off the quantitative lubricating mechanism that pressure goes out.
Background technique power system or transmission system, because of often being in rotation status, undermine mechanical parts for avoiding it excessively to wear away, lubricating fitting is generally all arranged, and each mechanical and power equipment or transmission system are because of required degree of lubrication difference, the fuel system of its lubricating fitting includes two kinds, and one is the continous way fuel feeding, and another is the discontinuous fuel feeding.Wherein, this continous way fuel feeding is by the motor pumping lubricant oil directly and continuously to be sent to each fuel feeding point in mechanical dynamic system or the transmission system, because of its demand and velocity-stabilization, so the motor pumping only needs running supply constantly to get final product; This discontinuous fuel feeding is then because of mechanical and power equipment or transmission system degree of lubrication difference, and regularly necessary or rationing, and be that the lubricant oil of trying to achieve in the pipeline can have level pressure and quantitative effect for each fuel feeding point, the general distributor that on pipeline, all is equiped with predetermined number, its operating principle is when motor pumping after autonomous pipe arrangement is sent to distributor with lubricant oil, because the oil mass in the pipe constantly flows into, cause the pressure in the distributor to continue to rise, and then force piston valve in the distributor to retreat to move and compress a spring.Space in the distributor also begins to measure pressure accumulation simultaneously, after reaching predetermined saturation point, lubricant pump shuts down, decompressing mechanism in the lubricant pump fuel tank impels the pressure in the main pipe arrangement to descend rapidly, that is the fluid in being responsible for begins to reflux, and path direction just makes a check valve in the distributor open to block refluxing opening, the fluid that while distributor space stores, just because of being subjected to the effect of spring recuperability, this piston valve spues from oil outlet, send to each fuel feeding point of machinery, and in after a period, repeat above-mentioned action again, and then reach the fuel system of discontinuous.Promptly, the effect of this decompressing mechanism is to make pumping to the pipeline fluid between distributor to take off pressure, hydraulic pressure in the distributor was pressed greater than being equipped with in the pipeline, and then impel check valve in the distributor to open and block refluxing opening, and send to each oiling point through the piston valve compression of distributor.But, press valve to be arranged in the fuel tank owing to take off, and, generally all be connected in series pressure regulator valve and use for preventing the too high oil pressure part that undermines of hydraulic pressure in the oil pipe.Therefore, cause pipeline serial connection too much and complicated, not only make assembling and be difficult for, and cause waste of material and increase cost, and easily make the fluid in the pipeline too high, the quality of damage lubricant oil because of the temperature of a specified duration that rub; In addition, when desire is adjusted the force value of pressure regulator valve, both hands must be placed fuel tank adjustment, cause both hands easily to be stained with grease and greasy, very trouble.
No. 361588 model utility of Taiwan patent announcement, the technological scheme of a kind of " Lubricant feeding oil way system structure improvement " is disclosed, mainly be that group is established an oil pump body in fuel tank, this oil pump body also can cooperate an electrical motor driven and turn round, wherein offer axle track in the oil pump body, this axle track end forms oil pressure group Pu, the transmission shaft of the moving motor of power supply can be arranged in the axial passage, and the bottom is assembled a pump oilgear and is helped the Pu in oil pressure, and in the oil pump body and offer oil leab, the one end communicates with oil pressure pump, and end communicates with oil outlet in addition; In addition, this oil pump body is respectively equipped with on oil leab and takes off pressure device and pressure relief device, suitably regulates in the time of can working as the charge oil pressure overload, to keep stable charge oil pressure.But wherein the design of the oil circuit in the oil pump body is compared with the pipe arrangement of conventional lubrication oil feeder, there is no too big variation, and the volume of its oil pump body is very big, not only causes cost of material to increase, and the load of overweight assembly increase driving source, forms energy waste.
The summary of the invention the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of reaching and conveniently make lubricant oil take off pressure fully to go out, and the improved quantitative lubricating decompressing mechanism that keeps certain oil pressure again and reduce cost in being responsible for.
The utility model solve the technical problem can be by realizing by the following technical solutions:
Design, a kind of improved quantitative lubricating decompressing mechanism of use comprise the oil pump seat, are provided with out oil needle valve, draining needle-valve, oil outlet and two draining holes in it, are provided with axis hole in its central authorities, are equipped with delivery connection in the one side in addition; Upper bed-plate, be located at this oil pump seat below, its system of central authorities is equipped with axis hole, and be equipped with oil outlet, two draining holes and some positioning holes around the axis hole, wherein, this goes out oil needle valve and draining needle-valve inside is respectively equipped with several elastic components, and the elasticity coefficient of elastic component is bigger than the elasticity coefficient that goes out the fuel-displaced elastic component of oil needle valve inner control in the draining needle-valve, and to take off the oil pressure coefficient that takes off when pressing in the oil pressure coefficient ratio main oil pipe of elastic component of pressure big and go out the oil needle valve inner control; Middle seat is to be located at this upper bed-plate below, and system is equipped with two axis holes on it, and is equipped with oil outlet, draining hole, oil-sucking hole and some positioning holes around axis hole; Lower bottom base is to be located at seat below in this, which is provided with two bosses, and be equipped with oil-sucking hole, two draining holes and some positioning holes around boss; Oil pump gear initiatively is located in this between the seat and lower bottom base, and its axial region can pass each above-mentioned axis hole; The passive oil pump gear is located in this between seat and the lower bottom base and with this active oil pump gear and is meshed.
Compare with prior art, technique effect of the present utility model is: can conveniently make lubricant oil take off fully that pressure goes out but can keep certain oil pressure again in being responsible for, and reduce cost.
