The vacuum pumping system of the vacuum moisture regaining machine is composed of a first-stage steam jet pump, a second-stage steam jet pump, a third-stage pump, a fourth-stage pump, a first condenser, a second condenser, corresponding pipelines and stop valves of the corresponding pipelines, wherein the third-stage pump and the fourth-stage pump are mechanical water ring pumps, the first-stage pump and the second-stage pump are steam jet pumps, and the condensers are located behind the corresponding steam jet pumps, play a role in reducing steam into water and are discharged through a water tank. The specific vacuum pumping process can be referred to as follows:
the method comprises the steps that a box body of the damping machine → a first-stage jet pump → a first condenser → a second-stage jet pump → a second condenser → a third-stage pump/a fourth-stage pump → evacuation, in actual work, four pumps are started in sequence, specifically, after the fourth-stage pump and the third-stage pump are started, when the vacuum degree of the box body reaches a first set value, the second-stage jet pump is started, then when the vacuum degree reaches a second set value, the first-stage jet pump is started, after the vacuum degree of the box body reaches a final target set value, the four pumps stop working at the same time, and the box body of the damping machine is vacuumized.
Technicians find that sundries enter a pipeline along with steam due to the fact that sealing rings of certain steam valves of the vacuum pumping system are damaged in the actual operation process of equipment, the sundries are often blocked at the position with the minimum diameter of the pipeline, namely a nozzle of a steam jet pump, and therefore the vacuum pumping time is prolonged, and even the vacuum degree cannot reach a set value and other abnormal conditions occur.
