Abstract
The invention relates to a novel lubricating pump and a volume occupation grease discharging method for preventing a plunger and a cylinder body from being worn. The lubricating pump consists of a plunger 1, a cylinder body 2, a grease absorbing check valve 3, a grease discharging check valve 4 and a spring 5; grease is filled into a closed chamber formed by the plunger 1, the cylinder body 2, the grease absorbing check valve 3, the grease discharging check valve 4 and the spring 5, when pressure oil is supplied from a P opening, the plunger 1 is pushed to compress the spring 5 to move rightwards, part of volume in the volume chamber is occupied, and grease of which the volume is the same as the volume in the closed volume chamber of the plunger 1 is extruded from the grease discharging check valve 4; and when return oil is injected from the P opening, grease discharging is finished, the plunger 1 moves leftwards under the action of the spring 5, and vacuum formed in the closed volume chamber is filled by the grease absorbed from a grease replenishing box 6 through the grease absorbing check valve to prepare for the next grease discharging. When the lubricating pump and the volume occupation grease discharging method is used, the contact and wear of the right part of the plunger 1 and the cylinder body 2 are prevented in the process of the grease discharging, and the pressure of the grease in the closed volume chamber is a little bit smaller than that in the P opening in the process of the grease discharging, so the grease does not leak towards the P opening with the increase of a gap between the plunger and the cylinder body. Therefore the grease discharging capacity and grease discharging pressure of the lubricating pump are not reduced.
Description
Technical field:
The present invention relates to a kind of lubricant pump and prevent its plunger and the volume of cylinder body premature wear occupies row's fat method.It is mainly used in and prevents that concrete pump and wind power generating set are with the lubricant pump plunger that the short stroke relative movement of high-speed high frequency causes between its plunger and cylinder body when pumping lubricating grease and the premature wear at cylinder body row fat working stroke position.It also is applicable to the lubricant pump of all kinds of production lines, electric locomotive and other all mechanical friction pairs.
Background technique:
Row's fat method of existing lubricant pump is formed airtight cavity volume by the plunger of lubricant pump with the cylinder body of its Spielpassung, and the volume that reduces this cavity volume by the motion of plunger is discharged the lubricating grease in the cavity volume again, and it arranges fat principle is volumetry.Lubricant pump is when pumping lubricating grease, the short stroke relative movement of high-speed high frequency easily causes the premature wear at row's fat working stroke position of plunger and cylinder body between its plunger and cylinder body, make that the gap at operation interval increases between the plunger of lubricant pump and cylinder body, because of increasing, the gap produces leakage, row's fat amount and row's fat pressure descend, and can not guarantee influences the host work life-span to the sufficient lubrication of friction pair.Because the turbidity test of lubricating grease are difficult to guarantee the rate of wear of having aggravated plunger and cylinder body.This state has become influences one of host work life-span and safe and reliable industry drawback.It also is the existing main failure forms that adopts the lubricant pump of volume row fat method.Although people have done constantly to improve at aspects such as the material of plunger and cylinder body and machining accuracies thereof, its effect does not still reach the usage requirement of main frame.
Goal of the invention:
Purpose of the present invention just is to preventing that effectively concrete pump and wind power generating set from providing row's fat method of a kind of new Lubricating Pump and anti-plunger and cylinder body premature wear with lubricant pump plunger and cylinder body premature wear.
Solution:
Technical solution of the present invention is that volume occupies method.Be lubricant pump by plunger 1, cylinder body 2, liposuction one-way valve 3, row fat one-way valve 4 and spring 5 formed.Its working principle is: by plunger 1, cylinder body 2, liposuction one-way valve 3 has been full of grease in the sealing cavity volume that row's fat one-way valve 4 is formed, move right when promoting plunger 1 pressure spring 5 to pressure oil, put in the identical grease of this sealing cavity volume inner volume with plunger 1 and discharged from row's fat valve 4 by the P confession.When the logical oil return of P mouth, row's fat finishes, and plunger 1 is moved to the left under the effect of spring 5, and the grease that the vacuum that produces in the sealing cavity volume is mended in the fat case 6 is mended full through 3 inspirations of liposuction one-way valve.Avoided contacting and wearing and tearing of in row's fat process plunger 1 right-hand member and cylinder body 2 so effectively.And the pressure that seals grease in the cavity volume in row's fat process will be lower than the pressure of P mouth, and the gap between plunger and cylinder body can not cause grease to leak to the P mouth because of long increase service time.
Sharpest edges of the present invention are: as long as the travel settings of plunger 1 just can guarantee muchly that the row's fat amount and the pressure of lubricant pump is constant.It is particularly suited for the lubricated of long, the jumbo that is difficult to safeguard of runtime such as wind power generating set.
Description of drawings: accompanying drawing 1 is a structure principle chart of the present invention.
Mode of execution: the specific embodiment of the present invention 1 is described as follows in conjunction with the accompanying drawings:
By plunger 1, cylinder body 2, liposuction one-way valve 3, be full of grease in the sealing cavity volume that row's fat one-way valve 4 is formed, move right when promoting plunger 1 pressure spring 5 to pressure oil by the P confession, occupied the partial volume in this cavity volume, put in the identical grease of this sealing cavity volume inner volume with plunger 1 and extruded from row's fat valve 4.When the logical oil return of P mouth, row's fat finishes, and plunger 1 is moved to the left under the effect of spring 5, and the grease that the vacuum that produces in the sealing cavity volume is mended in the fat case 6 is mended full through 3 inspirations of liposuction one-way valve.Get ready for arranging fat next time.
