Abstract
The utility model relates to a forced air cooled type rotary vane roller pump, which is used for manufacturing a vacuum pump and a vacuum pressure composite air pump. The outer surface of a rotary vane roller type pump body is provided with a plurality of axial radiating fins used for enlarging heat radiation area, a rotor shaft extended out of a rear cover is provided with impellers, and the outer surface of the impellers is provided with a fan housing. When the pump is run, the wind force generated by the impellers carry out forced air cooled operation to the pump body. The utility model has the advantages of simple structure, low cost, good effect, long service life, and convenient maintenance.
Description
The utility model belongs to positive displacement vacuum pump, can be used for making vacuum pump and vacuum-pressure composite air pump.
Existing blade roller-type pump [patent No. 93233179.3] is main by the pump housing, rotor, front and rear cover with Cylinder is installed in the combined type blade that is assembled in the blade Baltimore groove forms.A rotor is installed in pump chamber prejudicially, and outer garden of rotor and pump chamber internal surface are tangent.Several combined type blades are housed in the rotor, during the rotor rotation, by centrifugal force the Cylinder of combined type blade and the inwall of pump chamber are kept in touch, and roll along the pump inwall.Since with garden, the blade end arc of original sliding vane rotary pump, with the sliding friction of pump inwall, become the combination blade of rotary vane roller pump Cylinder, with the rolling friction of pump inwall.Thereby, reduce the power that pump consumed, reduce the temperature rise of pump and prolonged working life of pump.But because the to-and-fro motion of combination blade in rotor still produces sliding friction, so when running up, the temperature rise of pump is still very high.
The purpose of this utility model is to reduce the temperature rise of pump at a kind of energy forced air cooling of the problem design of the said goods existence, improves the forced air cooling type rotary vane roller pump of rotating speed.
The method that the utility model is finished: on the basis of blade roller-type pump, done several axial cooling fins at pump housing outer surface and be used to enlarge heat diffusion area.Fan blade is installed stretching out on the rotor shaft of bonnet, fan housing is installed in the fan blade outside.When pump turned round, the wind-force that fan blade produces flowed in the direction of the guiding lower edge of fan housing pump housing radiating fin, to pump housing forced air cooling.
The utility model has the advantages that: because the blade roller-type pump belongs to displacement pump, its working principle is that gas is sucked, and is compressed and discharge.According to the thermal engineering theory, the process of calming the anger is more near constant temperature process, and wasted work is just few more.So forced air cooling type rotary vane roller pump both can improve pump rotating speed, reduce the volume of pump, have simultaneously again the blade roller-type pump the power of reducing friction, reduce part wearing and tearing, reduce power consumption, prolong the advantage of the operating life of pump.Simultaneously, this pump structure is simple, and cost is low, and is easy to maintenance.
Accompanying drawing 1 is the longitudinal sectional view of the utility model agent structure, and Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment of the present utility model is: fan blade (2) is installed on the rotor shaft that stretches out bonnet (3) (6), and fan housing (1) is installed in the outside of fan blade, and fan housing is fixed on the pump postoperculum.Several axial cooling fins (5) have been done at the outer surface of the pump housing (4).Fan housing makes the wind-force of fan blade along the radiating fin axial flow on the pump housing outer surface, to pump housing forced air cooling.
Claims (1)
1, a kind of forced air cooling type rotary vane roller pump, comprise rotor, the pump housing, front and rear cover and Cylinder is installed in the combined type blade that is assembled in the blade Baltimore groove, it is characterized in that going up installation fan blade (2) at the rotor shaft that stretches out bonnet (3) (6), fan housing (1) is installed in the fan blade outside, fan housing is fixed on the pump postoperculum, has done several axial cooling fins (5) at the outer surface of the pump housing (4).
