Description

The mechanical rotor vacuum pump system of one way fuel feeding lubrication and seal
Technical field
The utility model relates to the mechanical rotor vacuum pump, particularly a kind of mechanical rotor vacuum pump system of one way fuel feeding lubrication and seal for the oil seal type of reduction vaporization or dry type acting.
Background technique
Reduction vaporization is the preferred option in current purification field, by the enforcement of this scheme, not only can save and heat energy, can also save the refrigeration energy, can also suppress the pyrolysis of feed liquid (material be distilled) simultaneously,
The urgent serious hope of people obtains the reduction vaporization vacuum technique that cost performance is higher thus.
The mechanical rotor vacuum pump of oil seal type or dry type acting, be rotated the cutting operation by rotor and make formed space between rotor and rotor cavity size occur or move to change and realize acting in the rotor cavity, but not by coordinate operation to realize the liquid-ring vacuum pump of acting with working solution.
The dry-type mechanical rotator vacuum pump is mainly by housing, be arranged at the rotor cavity within housing, the main acting such as air intake passage and the exhaust passage be communicated with the rotor cavity and the rotor that is placed in rotor inside cavity parts form, it only relies on rotor can realize acting with the relative running cutting operation between the rotor cavity, and at present typical dry-type mechanical rotator vacuum pump has Roots pump, screw vacuum pump etc.
Oil seal type mechanical rotor vacuum pump is on the dry-type mechanical rotator vacuum pump mainly does work the basis of parts, increased again gas-liquid separator (also claiming fuel reserve tank), gas-liquid separator is placed in the side of rotor cavity, inside is loaded with lubricant oil appropriate and periodic replacement, the gas-liquid separator bottom is provided with oil-feed port and communicates with the rotor cavity, inside communicates with the exhaust passage outlet, upper end is communicated with the exhaust outlet communicated with the external world, lower end is communicated with the oil drain out be isolated from the outside, it not only relies on rotor and moves and do work with the relative running cutting between the rotor cavity, also need the lubricant oil in gas-liquid separator both to serve as lubricant medium, also serve as sealing medium, running clearance between rotor and rotor cavity is sealed, the quality of lubricants performance not only is related to the working life of mechanical rotor vacuum pump thus, also be related to the size of the mechanical rotor vacuum pump speed of exhaust and the height of degree of vacuum, at present typical oil seal type mechanical rotor vacuum pump has sliding valve vacuum pump and trochoid vacuum pump etc.
If above-mentioned dry-type mechanical rotator vacuum pump is carried out to work for the vacuum field of reduction vaporization, because having sealing medium, the dry-type mechanical rotator vacuum pump do not participate in sealing so, so must keep less free gap between rotor and rotor cavity, certainly lead to thus following drawback:
Although 1. between rotor and rotor cavity, kept less free gap, leakage is caused in less gap at last, must sacrifice certain speed of exhaust and degree of vacuum thus.
2. the mechanical rotor vacuum pump is to rely on air-breathing acting and the exhaust of rotor in the rotor cavity to do work omnidistance acting, when carrying out the exhaust acting, pumped gas must be compressed, and pumped gas inevitable heat of compression that outwards discharges when compressed, when the heat of compression be released acts between rotor and rotor cavity, the outwards heat radiation simultaneously of rotor cavity, and the heat of rotor is difficult to outwards discharge, now the thermal expansion coefficient of rotor will be greater than the thermal expansion coefficient of rotor cavity, the less free gap of both maintenances is occupied by the rotor that is expanded thus, finally can not make rotor normally operation in the rotor cavity, otherwise can only be by adding the free gap between greater trochanter and rotor cavity or reducing operating pressure differential, can not make thus the mechanical rotor vacuum pump enter efficient working state.
3. the corrosion dirt (solid formation) that the free gap kept between rotor and rotor cavity is very easy to be carried secretly in pumped gas occupies, and can not make thus the mechanical rotor vacuum pump keep permanent clean running state.
If above-mentioned oil seal type mechanical rotor vacuum pump is carried out to work for the vacuum field of reduction vaporization, certainly leads to following drawback:
In exhaust acting process, because the rising of air pressure is very easy, coagulated both vapor compression in pumped gas is liquefied and sneaks in lubricant oil with other corrosion dirt (solid formation), because can not absorbing, lubricant oil appropriate and periodic replacement continues the heat of compression produced, not only make thus mechanical rotor vacuum pump temperature significantly raise, also will make the degree of purity of lubricant oil contaminated deteriorated rapidly, contaminated deteriorated lubricant oil not only affects its lubricity, in air-breathing acting process, because reducing, air pressure is very easy to make to sneak into the coagulated steam that is liquefied in lubricant oil vaporization again, significantly reduce the speed of exhaust and the degree of vacuum of mechanical rotor vacuum pump, and the corrosion dirt of sneaking in lubricant oil will forever retain in lubricant oil, toward and under the operating mode that renews, the vapourizing temperature of lubricant oil (being become the temperature of gas phase states of matter by the liquid phase states of matter) is not only more and more lower, moisture content in it and corrosion dirt are by cumulative, moisture content will constantly corrode various metals and continue to produce new corrosion dirt, cumulative corrosion dirt not only affects the mobility of lubricant oil, also be very easy to stop up oil circuit, thus, if can not keep the degree of purity of lubricant oil, the mechanical rotor vacuum pump is difficult to realize in the reduction vaporization field application efficiently so, although having installed cold-trap additional at the suction end of mechanical rotor vacuum pump, some technician can coagulate steam for catching, some technician has been installed gas ballast valve additional on the cavity of mechanical rotor vacuum pump can coagulate steam for discharge, but still can not thoroughly break away from the infringement of dirty lubricant oil for mechanical rotor vacuum pump function.
