Abstract
The utility model relates to a cooling structure for front/rear covers and end cover of Roots vacuum pump, comprising a pump body, fan blades, a front end cover, a rear end cover, a front cover, a rear cover, transmission gears, bearings, mechanical seals, lubrication oil and cooling water. Annular cooling water grooves are separately arranged in the front end cover and the rear end cover; cooling cavities are separately arranged in the front cover and the rear cover; a cooling water outlet and a cooling water inlet are separately arranged on the upper part and the lower part of the pump body. Because cooling cavities are arranged in the front cover and the rear cover of the Roots vacuum pump, and cooling water grooves are arranged in the end covers communicated with the front cover and the rear cover, the cooling area is four times larger than that of original cooling coils so that the operation temperature rise of the Roots vacuum pump is greatly reduced, achieving a more stable vacuum degree and a longer service life of the Roots vacuum pump.
Description
Technical field
The utility model relates to Roots pump, particularly a kind of forward and backward lid of Roots pump and the cooling structure of end cap.
Background technique
At present, the type of cooling of Roots pump has two kinds, and a kind of is natural air cooled, and another kind is to set up the coil pipe cooling unit in the fuel tank of the forward and backward lid of Roots pump, thereby makes the temperature of forward and backward lid obtain reduction to a certain degree.But because Roots pump is in the process of pressurized gas, gas produces high-speed friction by the fan blade and the pump housing and produces heat, cause having produced main thermal source, and bearing and the gear frictional heating when operation, it then only is secondary heat source, the type of cooling of taking is by the cooling coil cutting oil, cools off gear, bearing, front and rear covers and end cap indirectly by lubricant oil again, and cooling effect is relatively poor thus.
The model utility content
Task of the present utility model provides the cooling structure of a kind of improved Roots pump front and rear covers and end cap, and it is higher that it has solved the temperature rise in running of existing Roots pump, the problem that the cooling effect of its type of cooling is relatively poor.
Technical solution of the present utility model is as follows:
The cooling structure of a kind of Roots pump front and rear covers and end cap, it comprises the pump housing, fan blade, front cover, rear end cover, protecgulum, bonnet, driving gear, bearing, mechanical seal, lubricant oil and cooling water, is respectively equipped with the annular cooling water groove in described front cover and the rear end cover; Be respectively equipped with the cooling cavity in described protecgulum and the bonnet; The upper and lower of the described pump housing is respectively equipped with cooling water water outlet and cooling water water inlet tap.
Bosh in the described front cover is connected with cooling cavity in the protecgulum, and the interior cooling cavity of the bosh in the rear end cover and bonnet is connected.
Be provided with the cooling cavity in the described protecgulum and cool off cavity down.
Bosh in the described front cover is connected with following cooling cavity with the cooling cavity of going up of protecgulum.
Be provided with the cooling cavity in the described bonnet and cool off cavity down.
Bosh in the described rear end cover is connected with following cooling cavity with the cooling cavity of going up of bonnet.
The upper and lower of described protecgulum is respectively equipped with cooling water water outlet and cooling water water inlet tap.
The upper and lower of described bonnet is respectively equipped with cooling water water outlet and cooling water water inlet tap.
The cooling structure of Roots pump front and rear covers of the present utility model and end cap is in the forward and backward lid fuel tank of Roots pump the cooling cavity to be set, reduce the temperature rise of lubricant oil with this kind water-cooled form, thereby solved Roots pump temperature rise problem of higher in running.
Because the utility model is provided with the cooling cavity in the forward and backward lid of Roots pump, with set up the bosh that connects in the end cap that forward and backward lid is communicated with, therefore film-cooled heat has increased four times than the area of original cooling coil, the operation temperature rise of Roots pump is reduced greatly, thereby make that the degree of vacuum of Roots pump is more stable, and prolonged the working life of Roots pump.

Fig. 2 is the zoomed-in view at I cooling position among Fig. 1.
Fig. 3 is an A-A sectional view among Fig. 2.
Embodiment
Referring to Fig. 1 to Fig. 3, the utility model is the cooling structure of a kind of Roots pump front and rear covers and end cap, and it comprises the pump housing 1, fan blade 2, front cover 3, rear end cover 4, protecgulum 5, bonnet 6, driving gear 7, bearing 8, mechanical seal 9, lubricant oil medium 13 and cooling water.
Be respectively equipped with annular cooling water groove 11 in front cover 3 and the rear end cover 4.Be respectively equipped with the cooling cavity in protecgulum 5 and the bonnet 6.The upper and lower of the pump housing 1 is respectively equipped with cooling water water outlet 121 and cooling water water inlet tap 122.
As shown in fig. 1, cooling cavity 14 and following cooling cavity 10 are set in protecgulum 5.Bosh 11 in the front cover 3 is connected with following cooling cavity 10 with the cooling cavity 14 of going up of protecgulum 5.
Shown in Fig. 2 after and for example amplifying, cooling cavity 14 is set in bonnet 6 and cools off cavity 10 down.Bosh 11 in the rear end cover 4 is connected with following cooling cavity 10 with the cooling cavity 14 of going up of bonnet 6.
In conjunction with referring to Fig. 1 and Fig. 2, cooling water water outlet 121 and cooling water water inlet tap 122 are set respectively in the upper and lower of protecgulum 5.Upper and lower at bonnet 6 also is provided with cooling water water outlet 121 and cooling water water inlet tap 122 respectively.Cooling water with certain pressure is entered by the water inlet tap 122 of bonnet 6 bottoms, and the cooling cavity 10 of flowing through down flows to the pump housing 1 top through annular cooling water groove 11 again, at last through bonnet 6 go up cooling cavity 14, flow out from the water outlet 121 on bonnet 6 tops.In like manner, cooling water also is such flow process through protecgulum 5 and front cover 3.In whole cooling procedure, the heat that is produced in lubricant oil medium 13, the pump housing 1 and the running in the forward and backward lid 5,6 remains at a low-temperature condition.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
