Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, for the utility model discloses a two oil tank roots blower, including fan body 100 and oil tank 200, oil tank 200 has two and passes through the both sides of bolt fastening in fan body 100 respectively for store lubricating oil and for fan bearing and gear lubrication.
As shown in fig. 2, vertical oil inlet pipes 210 are fixed on the two oil tanks 200, oil inlet holes 211 are opened on the inner walls of the two oil inlet pipes 210, and the two oil inlet holes 211 are respectively communicated with the inner cavities of the two oil tanks 200. Pistons 220 are vertically slid in both of the oil inlet pipes 210, and an elastic member 230 for driving the pistons 220 to return is disposed in the oil inlet pipe 210. The length of the oil inlet pipe 210 is greater than the farthest sliding stroke of the piston 220, and the oil inlet hole 211 can be completely shielded by the initial state of the piston 220. When oiling to in the oil tank 200, lubricating oil exerts pressure to piston 220 for piston 220 gliding, thereby makes piston 220 expose inlet port 211, thereby makes lubricating oil get into in the oil tank 200, and after the oiling was accomplished, piston 220 no longer received pressure, and elastic component 230 can drive piston 220 and slide on and reset, thereby makes piston 220 block up inlet port 211, makes oil tank 200 reach sealedly. Because the oil inlet 211 is automatically opened and closed by using the elastic part 230 and the piston 220, manual operation is replaced, and therefore, the Roots blower is convenient for operation of workers when oil is injected into the Roots blower.
As shown in fig. 1, a funnel 240 is fixed to an inlet of the oil inlet pipe 210. The funnel 240 is provided to facilitate the filling of oil into the oil inlet pipe 210 by a worker.
As shown in fig. 2, the elastic member 230 includes a fixing rod 231, the fixing rod 231 is vertically and fixedly connected to the bottom wall of the oil inlet pipe 210, and a sliding rod 232 vertically slides in the fixing rod 231. A vertical return spring 233 is disposed in the fixing rod 231, and both ends of the return spring 233 respectively abut against the lower surface of the sliding rod 232 and the bottom wall of the fixing rod 231. When oil is filled into the oil tank 200, the lubricating oil applies pressure to the piston 220, so that the piston 220 slides down, the piston 220 drives the sliding rod 232 to slide down, the sliding rod 232 compresses the return spring 233, the oil inlet hole 211 is exposed by the piston 220, and the lubricating oil enters the oil tank 200. After the oil injection is completed, the piston 220 is no longer pressurized, and the sliding rod 232 slides upwards under the elastic force of the return spring 233, so as to drive the piston 220 thereon to slide upwards and return, so that the oil inlet hole 211 is blocked by the piston 220, and the oil tank 200 is sealed.
The two oil tanks 200 are provided with observation ports 250, and transparent glass is arranged in the observation ports 250. Oil outlets 260 are formed in the two oil tanks 200, and sealing pieces 270 used for sealing the oil outlets 260 are arranged on the two oil tanks 200. When the lubricating oil is seen to be black from the observation port 250, which indicates that the lubricating oil can no longer be used, it is necessary to activate the seal 270 so that the seal 270 opens the oil outlet 260, thereby allowing the lubricating oil to be discharged from the oil outlet 260.
As shown in fig. 3, the sealing member 270 includes a sliding rod 271 and a sealing ball 272, and the sealing ball 272 is disposed in the oil tank 200 and blocks the oil outlet 260. The sealing ball 272 is fixedly connected with the sliding rod 271, and the sliding rod 271 can penetrate through the oil outlet 260. An auxiliary plate 273 is fixedly connected to the slider 271, a vertical free-type gas spring 274 is fixedly connected to the oil tank 200, and one end of the free-type gas spring 274, which is far from the oil tank 200, is fixedly connected to the auxiliary plate 273. When the waste lubricating oil needs to be discharged, the free type gas spring 274 is started, so that the free type gas spring 274 contracts to drive the sliding rod 271 to move, the sliding rod 271 drives the sealing ball 272 to move, and the sealing ball 272 opens the oil outlet 260.
A circular sealing gasket 275 is fixedly connected in the oil outlet 260, and the sealing gasket 275 can be attached to the sealing ball 272. The sealing gasket 275 is provided to enhance the sealing performance of the oil outlet 260 and prevent the oil leakage from the oil outlet 260 when the roots blower is in operation.
The specific working process of this embodiment: when the oil inlet pipe 210 is filled with the lubricating oil, the piston 220 is pressed to slide down to drive the sliding rod 232 to slide down, and the return spring 233 is compressed, so that the oil inlet hole 211 is exposed by the piston 220. The lubricating oil enters the oil tank 200 from the oil inlet hole 211. After the oil injection is stopped, the piston 220 is not pressed, and the sliding rod 232 slides upwards under the elastic force of the return spring 233, so that the piston 220 is driven to return, and the oil inlet hole 211 is closed by the piston 220. Because the oil inlet 211 is automatically opened and closed by using the elastic part 230 and the piston 220, manual operation is replaced, and therefore, the Roots blower is convenient for operation of workers when oil is injected into the Roots blower.
