Quick flushing method for supplementing water before pumping and draining water after pumping of air conditioner water pipeline

Abstract

The invention relates to a quick flushing method for replenishing water before pumping and draining water after pumping of an air conditioner water pipeline. The method comprises the following steps that 1, a flushing loop can be connected after pressure testing of a pipeline is completed, and a flushing temporary piping is arranged; 2, a temporary water replenishing pump is used for replenishing water into the pipeline, exhausting is completed, and the temporary water replenishing pump is stopped; 3, a formal pump is started to carry out closed circulating flushing, the pressure is controlled to be 0.4-0.5 Mpa during circulating flushing, continuous flushing is carried out for about 1.5 hours, and the pump can be temporarily stopped to clean a filter for 2-3 times in the process; and 4, a drainage valve is opened, meanwhile, the temporary water replenishing pump is opened. The method of conducting water supplementing and drainage at the same time is adopted, the flushing pressure is controlled to be 0.5 Mpa, it is guaranteed that the water supplementing amount is larger than or equal to the water displacement, and the pipeline flushing pressure is high, the flow speed is high, the flushing time is short, and the flushing effect is good.

Description

technical field [0001] The invention relates to the field of air-conditioning water pipelines, in particular to a quick flushing method of replenishing water before the pump of the air-conditioning water pipeline and draining water after the pump. Background technique [0002] Existing technology: When flushing the water pipes of the air conditioning system, formal production pumps are often used. Due to the long pipeline and large diameter, the flow of the automatic water replenishment device of the system is limited, and the water is replenished in the return pipe, resulting in long flushing time for many large air conditioner pipes (Generally at least 8-10 hours), the flushing effect is poor, and cannot meet the requirements of debugging and operation. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art, and provides a fast flushing method for water supply before the pump of the air-conditioning water pipeline and drain...
