Description
Technical Field
The utility model belongs to the technical field of lubricating arrangement, concretely relates to oil cooling circulation negative pressure suction device.
Background
At present, the known common oil cooling circulation device is formed by simply splicing two parts together, wherein oil is transported from an oil storage tank to a rotary mechanical device such as a gear box, a bearing and the like by an oil pump and then flows back to the oil storage tank. However, as the volume of gas in the reservoir is compressed, the oil cooling cycle will continue to increase the pressure of the gas in the reservoir, thereby causing the oil pressure to increase. Although the sealing performance between the gaps of the rotating mechanical devices such as the gear box and the bearing is better, the oil leakage can not be caused under certain pressure. However, the critical value is often exceeded in long-term operation, so that the oil cooling circulation system is under high pressure, and the oil is forced to leak out of the mechanical gap of the gearbox. This often causes leakage of oil, which causes contamination of mechanical equipment, and also if there is a high temperature or flame outside, which may cause a fire, explosion, etc. More importantly, the oil is frequently leaked, so that the oil quantity in the oil storage tank is easily reduced, resources are wasted, and the environment is polluted by the leakage of the lubricating oil.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a simple structure, operation simple to operate, and can effectively prevent lubricating oil leakage to prevent polluted environment's oil cooling circulation negative pressure suction device.
The utility model adopts the technical proposal that: an oil cooling circulation negative pressure suction device comprises an oil storage tank, a gear box, an oil pump and an air pump; an oil outlet of the oil pump is connected with a nozzle in the gear box through an oil outlet pipe, and an oil inlet of the oil pump is connected with an oil storage tank through an oil inlet pipe; the bottom of the gear box is connected back to the oil storage tank through an oil return pipe; the air pump is connected with the air outlet of the oil storage tank through an exhaust pipe.
In the oil cooling circulation negative pressure suction device, the gear box is mounted on the top of the oil storage tank.
In the oil cooling circulation negative pressure suction device, the exhaust port is provided in a ceiling of the oil storage tank.
In the oil cooling circulation negative pressure suction device, a filter is arranged on the oil inlet pipe.
Compared with the prior art, the utility model has the advantages that the structure is simple, the cost is low, the utility model is provided with the air pump, the air pump pumps the gas in the oil storage tank, the pressure in the oil storage tank and the gear box is lower than the pressure of the outside air, and when the oil circulates into the gear box, the oil is prevented from being forced to be discharged from the mechanical gap of the gear box; resource waste and environmental pollution are prevented; this application adopts to have the circulation to cool off the gear box, provides the lubrication action for the gear box, reduces the friction between mechanical gear, the bearing.
Drawings
Fig. 1 is a structural view of the present invention.
Fig. 2 is a perspective view of the present invention.
In the figure: 1. the oil pump comprises a gear box, an impeller 2, an oil outlet pipe 3, an oil pump 4, a motor I5, a motor II 6, a coupling 7, an oil return pipe 8, an oil inlet pipe 9, an air pump 10, a motor III 11, an exhaust pipe 12 and an oil storage tank 13.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present invention comprises an oil storage tank 13, a gear box 1, an oil pump 4 and an air pump 10; the oil pump 4 is connected with a motor I5, and the motor I5 realizes the work of the oil pump 4. The oil outlet of the oil pump 4 is connected with a nozzle in the gear box 1 through an oil outlet pipe 3, and the oil inlet of the oil pump 4 is connected with an oil storage tank 13 through an oil inlet pipe 9. Be equipped with the filter on the oil inlet pipe 9, filter lubricating oil, prevent that the iron fillings that gear box 1 wearing and tearing produced from plugging up the nozzle. The bottom of the gear box 1 is connected back to the oil storage tank 13 through an oil return pipe 8; the air pump 10 is connected with the motor III 11, the motor III 11 realizes the work of the air pump 10, and the air pump 10 is connected with an air outlet of the oil storage tank 13 through an exhaust pipe 12. The exhaust port is provided in the ceiling of the oil reservoir 13.
The utility model discloses during the use, oil pump 4 rotates under motor I5's effect for oil in the oil storage tank 13 is connected to oil pump 4 through advancing oil pipe 9, then carries the gear box 1 in oil through going out oil pipe 3. The motor II 6 drives the impeller 2 to rotate through the coupling 7 and the gear box 1. After the oil cools and lubricates the internal mechanical parts of the gear box 1, the oil is returned to the oil storage tank 13 through the oil return pipe 8. The air pump 10 is rotated by the motor III 11 to remove the air in the oil storage tank 13 through the exhaust pipe 12, so that the air pressure in the oil storage tank 13 and the gear box 1 is lower than the pressure of the outside air. Thus, when oil is circulated into the gearbox, the oil is prevented from being forced to leak out of the mechanical crevices of the gearbox due to the fact that the external air pressure is greater than the air pressure in the gearbox 1.
