The front and rear ends of a blower shell are respectively connected with a front wallboard and a rear wallboard; matched impellers are respectively arranged on a main and an auxiliary shafts in the blower shell; constant speed drive gears reversely rotating are respectively arranged on the main and the auxiliary shafts; a gear cover shell out of the gear is connected with the front wallboard. A driving shaft is arranged on the wallboard through a bearing, a bearing seat and a seal element; the upper part of the blower shell is provided with an air outlet; the lower part of the blower shell is provided with an air inlet. The gear cover shell and a bearing cap are all the double-layer cooling water jacket structure; a water inlet and a water outlet are arranged on the jacket.
Description
A kind of have the Roots blower of novel cooling mechanism to relate to a kind of pump, particularly a kind of blower that is used to carry elastic fluid.
An additional fuel tank is adopted in the gear of existing D60 type Roots blower and bearing lubrication, and water-cooling tube is arranged in the fuel tank, utilizes cold water to oil cooling but, this cooling mechanism is complicated, and in case the manufacture cost height is oil pump, Oil pump electrical machinery breaks down or oil pipe when blocking, and gear and bearing often burn.
The purpose of this utility model provides a kind of design proposal that the Roots blower of novel cooling mechanism is arranged, it is improvement to the D60 Roots blower, its cooling mechanism is simpler, easy to maintenance, low cost of manufacture, good cooling results, gear and bearing generally can not burn out, and can economize on electricity, reduce user cost.
Specific embodiments of the present utility model is: a kind of Roots blower that novel cooling mechanism arranged is the improvement to existing D60 type Roots blower, before its Fan casing, the rear end is connected with rear wall plate with front wallboard respectively, master in the Fan casing, pay the impeller that coupling is housed respectively on the axle, main, pay the constant speed driving gear that counterrotating is housed respectively on the axle, the outer gear house of gear is connected with front wallboard, driving shaft passes through bearing, bearing support and Sealing are contained on the wallboard, exhaust outlet is arranged at Fan casing top, there is intake grill both sides, Fan casing bottom, gear house and bearing cap are double-deck cooling water jecket structure, water intake and water outlet are arranged on the chuck, lubricant oil is cooled off by the chuck inwall, oilhole is arranged on the gear house, oil-hole plug is arranged on the oilhole, utilize oilhole can measure the temperature of fuel head and oil.Forward and backward wallboard is double-deck overall structure, and bearing support is connected with the wallboard upper strata, and Sealing is connected with wallboard lower floor; The fan blade of impeller has two leaves or three leaves.Main shaft is connected with motor.
Major advantage of the present utility model is: utilize cold water in the chuck of gear house and bearing cap to chuck inwall and lubricant oil cooling, not only cooling mechanism is fairly simple, easy to maintenance, low cost of manufacture, good cooling results, and saved water-cooling tube in additional fuel tank, oil pump and the fuel tank in the existing D60 type Roots blower, favourable economize on electricity reduces manufacturing cost and use cost.
