Abstract

The invention relates to the field of refrigeration maintenance, and provides a vacuum pump and recycling machine integrated machine structure which is convenient to use, high in reliability, low in cost, and capable of saving energy and protecting the environment. The technical problems that in the prior art, during refrigeration maintenance, a recycling machine and a vacuum pump need to be separately configured, carrying and using are inconvenient, and the purchasing cost is high are solved. The vacuum pump and recycling machine integrated machine structure comprises a motor, the two ends ofan output shaft of the motor extend out of the motor, the two ends of the output shaft are connected with a rotor shaft of the vacuum pump and a compressor crankshaft on the recycling machine throughunidirectional clutch bearings correspondingly, when the rotation direction of the output shaft is changed, one end of the output drives the corresponding vacuum pump or a corresponding compressor torotate synchronously, and the other end of the output shaft is separated from the corresponding vacuum pump or the corresponding compressor.

Description

technical field [0001] The invention relates to the field of refrigeration maintenance, in particular to an integrated machine structure of a vacuum pump and a recovery machine which is convenient to use, high in reliability, energy-saving and environment-friendly. Background technique [0002] In the existing refrigeration maintenance field, the general refrigerant recovery machine and the vacuum pump are configured separately. During the refrigeration maintenance process, the refrigerant in the refrigeration system needs to be pumped out with a recovery machine, after the maintenance is completed, the system is evacuated with a vacuum pump, and finally the refrigerant is refilled into the system. It is necessary to carry a recovery machine and a vacuum pump for maintenance, which is not only inconvenient to carry and use, but also requires high procurement costs for separately configuring the recovery machine and vacuum pump, resulting in increased user costs.
