Cleaning equipment and cleaning method for small-pipe diameter pipeline

Abstract

The invention relates to the technical field of pipeline cleaning, in particular to cleaning equipment and a cleaning method for a small-pipe diameter pipeline. The cleaning equipment comprises a pump unit, a first connection pipe, a second connection pipe, a third connection pipe, a fourth connection pipe, a fifth connection pipe, a sixth connection pipe, a first two-inlet one-outlet valve, an air supply device and a four-way reversing valve; the outlet of the first connection pipe selectively communicates with the third connection pipe or the fourth connection pipe through the four-way reversing valve; the second connection pipe is connected with the four-way reversing valve; the third connection pipe and the fourth connection pipe are separately connected with two ends of the to-be-cleaned pipeline; the inlet of the first connection pipe selectively communicates with the outlet of the fifth connection pipe or the outlet of the sixth connection pipe through the first two-inlet one-outlet valve; the inlet of the fifth connection pipe is connected with the air supply device; the inlet of the sixth connection pipe communicates with a cleaning tank; the pump unit is arranged on the sixth connection pipe; and the outlet of the second connection pipecommunicateswith a sewage tank. According to the cleaning equipment, fewer components are adopted; a series of operation of cleaning of the pipeline can be realized; and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a cleaning device and a cleaning method for small-diameter pipelines. Background technique [0002] The cooling coil pipelines of electrical components, the coolant pipelines of antennas or radar equipment, and the heating or cooling pipelines of small components are all small in diameter, and the materials are generally rubber hoses, aluminum alloys, special material alloys, etc. The above pipelines generally require For pressure operation, there will be dirt on the inner wall after one cycle of use, so the pipeline needs to be cleaned during inspection and maintenance. [0003] Traditional methods include: 1. Use nitrogen or compressed air to blow out the remaining liquid in the pipeline, but the pipeline cannot be cleaned and post-treated, so that the pipeline cannot be reused; 2. Use chemical agents to soak and clean, which can be cleaned The pipeline has damage to...
