Summary of the invention
In order to overcome the large deficiency of existing power plant vibrating noise.The utility model provides a kind of built-in oil pump power plant, and these power plant comprise hydraulic oil container, power plant, changement, return line, detection device, oil pump outlet line road, A power pipeline and B power pipeline.Power oil is incorporated in changement by power plant, and changement realizes the control to supercharging equipment.Two cover power plant are arranged on the top of hydraulic oil container, in power plant, oil pump invades in hydraulic oil, in power plant, the oil outlet of oil pump is connected by oil pump outlet line road with the cover plate of hydraulic oil container, power oil is drawn from cover plate, by A power pipeline and B power pipeline, the power oil of two cover power plant is accessed changement again, the oil return of changement is flowed back in hydraulic oil container by return line.Detection device is connected with the pressure tap in changement by steel pipe, detects the force value of the pressure oil that two cover power plant pump.Because the oil pump of power plant invades in hydraulic oil, the vibration of oil pump is weakened by hydraulic oil, thus reduces the noise of power plant generation.Changement is integrated on hydraulic oil container, when hydraulic piston type compressor operating, the reversing impact that changement produces passes to whole fuel tank by the cover plate connection of hydraulic oil container, because hydraulic oil has absorbing effect, changement impact shock is weakened, thus reduces the vibrating noise of power plant.
The utility model solves the technological scheme that its technical problem adopts: a kind of built-in oil pump power plant, are characterized in comprising hydraulic oil container 1, power plant 2, changement 3, return line 4, detection device 5, oil pump outlet line road 6, A power pipeline 7 and B power pipeline 8.Described power plant 2 have two covers, are connected by pipeline, are incorporated in changement 3 by power plant 2 by power oil, and changement 3 overlaps control system integrations in one by two, realizes the control to supercharging equipment.Two cover power plant 2 are arranged on the top of hydraulic oil container 1, in power plant 2, oil pump invades in hydraulic oil, in power plant 2, the oil outlet of oil pump is connected by oil pump outlet line road 6 with the cover plate of hydraulic oil container 1, power oil is drawn from cover plate, by A power pipeline 7 and B power pipeline 8, the power oil of two cover power plant 2 is accessed changement 3 again, the oil return of changement 3 is flowed back in hydraulic oil container 1 by return line 4.Detection device 5 is connected with the pressure tap in changement 3 by steel pipe, detects the force value of the pressure oil that two cover power plant 2 pump.
The beneficial effects of the utility model are: these power plant comprise hydraulic oil container, power plant, changement, return line, detection device, oil pump outlet line road, A power pipeline and B power pipeline.Power oil is incorporated in changement by power plant, and changement realizes the control to supercharging equipment.Two cover power plant are arranged on the top of hydraulic oil container, in power plant, oil pump invades in hydraulic oil, in power plant, the oil outlet of oil pump is connected by oil pump outlet line road with the cover plate of hydraulic oil container, power oil is drawn from cover plate, by A power pipeline and B power pipeline, the power oil of two cover power plant is accessed changement again, the oil return of changement is flowed back in hydraulic oil container by return line.Detection device is connected with the pressure tap in changement by steel pipe, detects the force value of the pressure oil that two cover power plant pump.Because the oil pump of power plant invades in hydraulic oil, the vibration of oil pump is weakened by hydraulic oil, thus reduces the noise of power plant generation.Changement is integrated on hydraulic oil container, when hydraulic piston type compressor operating, the reversing impact that changement produces passes to whole fuel tank by the cover plate connection of hydraulic oil container, because hydraulic oil has absorbing effect, changement impact shock is weakened, thus reduces the vibrating noise of power plant.
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
