Abstract
A kind of cooling structure of Roots pump, comprise cylinder body (13) and inner chamber (14), the forward and backward two end cap that it is characterized in that described cylinder body (13) is respectively provided with two separate cooling water tanks, these four separate cooling water tanks are communicated by water-cooling tube, cooling water is forced to introduce, Forced water cooling is carried out to cylinder body.The cooling structure of Roots pump of the present invention carries out pressure cooling to vacuum pump.This kind of cooling structure is in the forward and backward two end cap of cylinder body, be respectively provided with two separate cooling water tanks, and these four separate cooling water tanks are communicated by water-cooling tube, are forced to introduce by cooling water, carry out Forced water cooling to cylinder body.
Description
Technical field
The present invention relates to a kind of cooling structure of Roots pump, belong to vacuum pump technology field.
Background technique
At present, Roots pump is a kind of rotary positive-displacement vacuum pump, when vacuum pump operation, discontinuous gas is got rid of after rotor compression, make to there is larger operating pressure differential between the inlet/outlet of the pump housing, due to Roots pump temperature rise with compress when efficiency and have direct relation, the heat produced of usual pressurized gas is shed by the pump housing.But in a low voltage state, the heat that rotor absorbs not easily sheds, and when the pressure of vacuum pump exceedes specified value, the too high meeting of temperature of rotor causes gap too small, makes vacuum pump cisco unity malfunction.
Summary of the invention
The invention provides a kind of cooling structure of Roots pump, to overcome above-mentioned defect.The object of this invention is to provide a kind of connecting pipeline simple, the cooling structure of the Roots pump that cooling effectiveness is high.
Technological scheme of the present invention:
A kind of cooling structure of Roots pump, comprise cylinder body 13 and inner chamber 14, the forward and backward two end cap of described cylinder body 13 is respectively provided with two separate cooling water tanks, these four separate cooling water tanks are communicated by water-cooling tube, cooling water is forced to introduce, Forced water cooling is carried out to cylinder body.
Described four separate cooling water tanks are the first cooling water tank 1, second cooling water tank 4, the 3rd cooling water tank 7 and the 4th cooling water tank 10.
Described first cooling water tank 1 is connected with the first water outlet 2 and the first water intake 3.
Described second cooling water tank 4 is connected with the second water outlet 5 and the second water intake 6
Described 3rd cooling water tank 7 is connected with the 3rd water outlet 8 and the 3rd water intake 9.
Described 4th cooling water tank 10 is connected with the 4th water outlet 11 and the 4th water intake 12.
The invention has the beneficial effects as follows:
The cooling structure of Roots pump of the present invention carries out pressure cooling to vacuum pump.This kind of cooling structure is in the forward and backward two end cap of cylinder body, be respectively provided with two separate cooling water tanks, and these four separate cooling water tanks are communicated by water-cooling tube, are forced to introduce by cooling water, carry out Forced water cooling to cylinder body.
Accompanying drawing explanation
Fig. 1 is form structure schematic diagram of the present invention.
Fig. 2 is along A-A direction sectional view in Fig. 1.
In figure: 1 be the first cooling water tank, 2 be the first water outlet, 3 be the first water intake, 4 be the second cooling water tank, 5 be the second water outlet, 6 be the second water intake, 7 be the 3rd cooling water tank, 8 be the 3rd water outlet, 9 be the 3rd water intake, 10 be the 4th cooling water tank, 11 be the 4th water outlet, 12 be the 4th water intake, 13 be cylinder body, 14 be inner chamber.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As Fig. 1, a kind of cooling structure of Roots pump, comprises cylinder body 13 and inner chamber 14, the forward and backward two end cap of cylinder body 13 is respectively provided with two separate cooling water tanks, these four separate cooling water tanks are communicated by water-cooling tube, are forced to introduce by cooling water, carry out Forced water cooling to cylinder body.
Four separate cooling water tanks are the first cooling water tank 1, second cooling water tank 4, the 3rd cooling water tank 7 and the 4th cooling water tank 10.
First cooling water tank 1 is connected with the first water outlet 2 and the first water intake 3.
Second cooling water tank 4 is connected with the second water outlet 5 and the second water intake 6
3rd cooling water tank 7 is connected with the 3rd water outlet 8 and the 3rd water intake 9.
4th cooling water tank 10 is connected with the 4th water outlet 11 and the 4th water intake 12.
The present invention connects cylinder body four water tank water intake joints with cooling water flexible pipe successively and communicates with water output connector water tank, and connects with cooling source and communicate.Improve the cooling effect of vacuum pump so greatly, effectively improve the working state of vacuum pump.
Embodiment recited above is described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under design concept prerequisite of the present invention; the various modification that in related domain, common engineers and technicians make technological scheme of the present invention and improvement; all should fall into protection scope of the present invention, the technology contents of request protection of the present invention is all recorded in detail in the claims.
