A refrigerant filling machine

Abstract

The invention discloses a refrigerant filling machine which comprises a filling machine frame. The filling machine frame is fixedly connected with a speed changing box used for mounting of a gear transmission mechanism. Two power input ends are arranged at the upper end of the speed changing box, and two power output ends are arranged at the lower end of the speed changing box. The two power input ends are connected with two drive motors respectively. The two power output ends are connected with a first pressure pump and a second pressure pump respectively. The input end of the first pressure pump and the input end of the second pressure pump are connected with a refrigerant container used for storing refrigerant through first refrigerant pipelines respectively, and the output end of the first pressure pump and the output end of the second pressure pump are connected with filling gun heads through second refrigerant pipelines respectively. The filling machine is further provided with a charger. The refrigerant filling machine is provided with two filling lines, a refrigerator or other refrigeration devices can be independently filled with refrigerant at the same time, even though parts on one filling line break down or need to be maintained, the other filling line can still work, and therefore equipment reliability is improved greatly.

Description

technical field [0001] The invention relates to the technical field of refrigerant filling, in particular to a refrigerant filling machine. Background technique [0002] Filling machines are now used in various fields of society, and with the continuous development of industrial society, their use is increasing. For example, in the refrigeration industry, the production of refrigeration equipment such as refrigerators and air conditioners has been increasing year by year. As the main equipment for injecting refrigerant into refrigeration equipment, refrigerant filling machines play a huge role in the production of refrigeration equipment. [0003] Existing refrigerant charging machines are generally equipped with only one charging gun head to charge the refrigeration equipment with refrigerant. When the charging machine breaks down or needs maintenance during use, the charging work cannot continue because there is no backup equipment. In addition, because the gas or liquid ...

Problems solved by technology

[0003] The existing refrigerant filling machine is generally only equipped with a filling nozzle to fill the refrigeration equipment with refrigerant. When the filling machine breaks down or needs maintenance during use, the filling work will not continue because there is no backup equipment.

In addition, because the gas or liquid pumped by the existing vacuum device is not filtered before entering the vacuum pump, impurities will easily enter the vacuum pump and affect the performance of the vacuum pump. Once the vacuum degree does not meet the requirements, the cooling effect of the refrigeration equipment will be affected
