Problems solved by technology
It can be seen that during the oil injection process, if the flow meter fails or is damaged, the staff cannot get feedback at the first time, so there are situations of leakage, under-filling or over-filling of refrigerant oil, thus affecting the quality of the unit due to low filling accuracy

The invention discloses an infusion method and infusion equipment. The method comprises the following steps: firstly, the total amount of a liquid medium flowing from an initial container is metered via a first flow meter, and a first metering result is obtained; secondly, the total amount of the liquid medium metered at the first time is metered via a verification metering device, and a second metering result is obtained, and the liquid storage metered at the second time is stored in a middle container; thirdly, a first difference value is obtained by comparing the first metering result with a second metering result, whether the first difference value is within an allowable range or not is judged, if so, the liquid medium in the middle container is injected into the target container, and otherwise, the infusion is over. The invention discloses infusion equipment, which ensures the accuracy of the infusion process step by step. According to the invention, the defect of inaccurate infusion caused by the metering error of the flow meter is avoided, so that accurate infusion is achieved.
Description
technical field [0001] The invention relates to the field of perfusion methods, in particular to a perfusion method and a perfusion device. Background technique [0002] In a variety of technical fields, the process of manufacturing or repairing products will encounter the operation of pouring a certain amount of a certain liquid medium into the target device, for example, pouring a certain amount of gasoline into the cylinder, or pouring a certain amount of liquid medium into the target equipment A certain amount of lubricating oil is poured into the mechanical parts. In addition, in the process of producing multi-connected central air conditioners, a certain amount of refrigeration oil needs to be poured into the air conditioning unit. However, the perfusion equipment used in the perfusion process in various technical fields uses only one flowmeter to measure the liquid medium being perfused, and the flowmeter measures while perfusing without interrupting the perfusion pro...
