Description
Technical field
The utility model relates to the maintenance maintenance device of air-conditioning unit, relates in particular to air-conditioning unit oil charging-discharging device for a kind of hospital.
Background technology
According to prior art, the air-conditioning system of using in hospital, adopts the closed circuit comprehensive utilization form of recuperation of heat form more, in refrigeration, can save better the energy for providing heat energy with hot department, reduces refrigeration and with hot integrated cost.On the multiple unit of prior art, be provided with oil storage barrel, adopt oil pipe to be connected with compressor, oil plant in oil storage barrel can strengthen gradually concentration after long-time use, finally the concentration because of fluid forms too greatly oil pipe blocking, after the situation of generation oil pipe blocking, will take oil storage barrel apart, pour out the waste oil in oil storage barrel, whole operation bothers very much.Chinese patent 201320309956.0 discloses a kind of " heat-recovery multi-connected air conditioning group oil charging-discharging device ", it is the draining valve that is provided with discharge waste oil on the oil inlet pipe of oil storage barrel being connected to, draining valve also can use as inlet valve simultaneously, for concrete use provides certain convenience.But the concentration that this improvement has been ignored because of fluid increases the oil storage barrel wall built-up problem forming, situation at the serious wall built-up of oil storage barrel, even if changed new fluid, its comprehensive new fluid concentration still exceeds standard, and therefore concrete use procedure can not get a desired effect.
Utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art part, air-conditioning unit oil charging-discharging device for a kind of hospital is provided, both can to the fluid in oil storage barrel, implement to change easily, can implement easily the cleaning of oil storage barrel inside again, avoid the residual problem of super concentration fluid wall built-up.
Air-conditioning unit oil charging-discharging device for a kind of hospital described in the utility model, includes driven at low speed device, oil-feed control valve, oil inlet pipe, central shaft, bristle brush, vertical fuel drum, three way type draining valve, oil exit pipe, cuts valve and heat energy pipe.Vertical fuel drum is the main component of air-conditioning unit oil charging-discharging device for a kind of hospital described in the utility model, integral body is vertical cylindrical tank shape structure, middle position at vertical fuel drum upper end cover, with the form of inserting, be provided with central shaft, in the main body of central shaft, be provided with the bristle brush of spiral form, in the upper end of central shaft, specifically the upper end of the central shaft on vertical fuel drum upper end cover, is connected with driven at low speed device.Said driven at low speed device, adopts motor configurations to be output as the reductor of 10 revs/min.Upper end cover one side at vertical fuel drum, is provided with oil inlet pipe, is provided with oil-feed control valve on oil inlet pipe.The bucket end one side at vertical fuel drum is provided with oil exit pipe, and oil exit pipe, near the bucket position, the end of vertical fuel drum, is provided with three way type draining valve, on the oil exit pipe below three way type draining valve, is provided with and cuts valve.When using three way type draining valve to carry out oil extraction operation, generally should close the valve that cuts on oil exit pipe.At the bucket end opposite side of vertical fuel drum, be provided with the heat pipe of comprehensive utilization heat energy, on said heat pipe, be provided with control valve.
Air-conditioning unit oil charging-discharging device for a kind of hospital described in the utility model, overall structure is simple, installation and easy for operation, good stability, reliability is high.Use air-conditioning unit oil charging-discharging device for a kind of hospital described in the utility model, both can to the fluid in oil storage barrel, implement to change easily, can implement easily the cleaning of oil storage barrel inside again, avoid the residual problem of super concentration fluid wall built-up, can improve preferably the refrigerating efficiency of hospital's air-conditioning unit, namely improved by hot efficiency simultaneously.
