Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, in particular to a plug device for a water ring vacuum pump. Background Art

[0002] Vacuum water ring pumps are widely used in water treatment return water systems and are an important part of ensuring the normal operation of the return water pump. When the operating liquid level of the system return water tank is below the operating liquid level of the return water pump, the horizontal return water pump cannot transport water to the return water tank. The water ring vacuum pump is required to pump the return water pump cavity into a vacuum state, and at the same time, the return water pump cavity is filled with turbid ring water before the return water pump starts to operate. The quick plug and PU air pipe are responsible for the connection between the vacuum pump water tank and the return water pump cavity, and also serve as the opening point for the quick exhaust of the pump cavity. The damage of the quick connector and the air pipe will directly affect the system return water operation.

[0003] The following defects exist: in normal use, the PU air pipe connected to the quick plug will be impacted by water flow during operation, causing the PU pipe to swing, which can easily damage the quick plug, and the PU pipe diameter will be thinned by erosion by turbid circulating water. The PU pipe will rupture, causing the return pump vacuum to be destroyed and unable to operate. At the same time, water spraying from damaged air pipes and plugs will pose a safety hazard to on-site electrical equipment. Utility Model Content
