Abstract
The invention discloses a single-stage blade pump for dimethyl ether vehicles, comprising a blade, a shaft pin screw, a screw, an end cover, a pump cavity, an oil-taking ring, a small oil passage, a pump body shaft sleeve, a framework seal, a retainer ring, a snap spring, a shaft, an oil-outlet cavity. A swirl oil line is arranged on the inner surface of the pump body shaft sleeve axially; and by the swirl oil line, the quantity of lubrication oil between the shaft and the pump body shaft sleeve is improved, the problems of easy occurrence of shaft clasping of the single-stage blade pump and short service life of the framework seal are solved, and reliable equipment guarantee for taking dimethyl ether as the fuel for vehicles to replace diesel is provided.
Description
Technical field:
The present invention relates to a kind of single-stage blade pump, is a kind of single-stage blade pump for dimethyl ether vehicle that is applicable to.
Background technique
At present, because media such as dimethyl ether, lubricity own is bad, general single-stage blade pump for dimethyl ether vehicle stability in use is poor, seize often occurs, and reinforced seal damages, reduce service time, increase maintenance cost, cause difficulty for the application of this clean energy resource.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art, provide a kind of by in single-stage blade pump pump housing axle sleeve, being provided with spiral oil line, improve the lubrication effect between axle and the pump housing axle sleeve, outside framework oil seal adopts and is fit to the material that dimethyl ether uses, reduce the corrosion of dimethyl ether, improve the stability in use of unit vane oil pump, provide good fuel feeding lubricating condition for axle and pump housing axle sleeve, make axle all be in the cloth oil condition at whole axial-radial at work spiral oil in service line; By spiral oil line is set at single-stage blade pump, preferably resolve problems such as the frequent seize problem of single-stage blade pump, reinforced seal working life is short, for dimethyl ether substitutes diesel oil as vehicle fuel, a kind of single-stage blade pump for dimethyl ether vehicle that provides reliable device to ensure.
The technical solution adopted in the present invention is:
A kind of single-stage blade pump for dimethyl ether vehicle, by blade, pivot pin screw, screw, end cap, pump cavity (stator), little oil duct, pump housing axle sleeve, reinforced seal, back-up ring, jump ring, axle with go out oil pocket and form, it is provided with spiral oil line vertically on the internal surface of pump housing axle sleeve, the groove type helix of spiral oil line for being provided with on the internal surface of pump housing axle sleeve.In single-stage blade pump for dimethyl ether vehicle work when operation,, the rotating band moving vane of axle rotates, and the rotation of blade makes oil circuit that certain pressure arranged, and the spiral oil line of oil by being provided with of certain pressure arranged, and reaches the good lubrication of axle and pump housing shaft room.
The technical solution adopted in the present invention can also be:
Spiral of the present invention oil line is left-handed or the oily line of right hand helix, the starting point of spiral oil line with go out oil pocket and be communicated with, the terminal point of the oily line of spiral is communicated with installation reinforced seal ring cavity.
Spiral of the present invention oil line is for singly revolving spiral oil line, or spiral oil line is that double end is revolved spiral oil line or bull is revolved the oily line of spiral.
The transverse section of spiral oil line of the present invention is a V-arrangement, or the transverse section of described spiral oil line is U-shaped or semicircle.
The invention has the beneficial effects as follows:
1, by in pump housing axle sleeve, being provided with spiral oil line, improved the lubricants capacity between axle and the pump housing axle sleeve, this spiral oil line is in service for axle and pump housing axle sleeve provide good fuel feeding lubrication effect in work, makes axle all be in the cloth oil condition at whole axial-radial;
2, the present invention is owing to be provided with spiral oil line, accelerated medium and lubricant oil flowing between axle and pump housing axle sleeve,, played cooling action axle and pump housing axle sleeve for the formation of oil film in time provides new lubricant oil, prevent its elevated temperature deformation, thereby prolonged working life.
3, the spiral of setting of the present invention oil line has been accelerated the circulating load of medium and lubricant oil, and the operating conditions of outside framework oil seal has also been had good improvement, avoids the phenomenon of oil starvation cavitation erosion and heating, has prolonged the working life of oil sealing.
4, the spiral oil line of the present invention's setting has solved single-stage blade pump and has been prone to seize and reinforced seal short problem in working life, for dimethyl ether substitutes diesel oil as vehicle fuel, provides the reliable device guarantee.
