Static pressure testing device for integrated packaging mechanical seal

Abstract

The invention discloses a static pressure testing device for an integrated packaging mechanical seal, which comprises a rack, and is characterized in that the bottom end of the rack is fixedly provided with an integrated packaging mechanical seal, the top end of the rack is fixedly provided with an oil cylinder, a piston rod of the oil cylinder is fixedly connected with the top end of a ventilating disc through a flange, the middle part of the ventilating disc is fixedly provided with an air inlet pipe, one end of the air inlet pipe is fixedly provided with an air inlet valve, the other end ofthe air inlet pipe is fixedly provided with a pressure meter, the middle part of the air inlet pipe is provided with an air outlet, and the bottom end of the ventilating disc is fixedly provided witha cavity. According to the static pressure testing device for the integrated packaging mechanical seal, the ventilating disc, the cavity and the integrated packaging mechanical seal are compressed through extending the piston rod of the oil cylinder so as to quickly form a sealed cavity, the air pressured is charged for testing, the pressure of the hydraulic oil cylinder is provided by a hydraulic station, and the pressure output is stable, so that manual bolt locking is avoided, and the pressure testing efficiency if improved so as to meet the requirement of batch production of the integrated packaging mechanical seal.

Description

technical field [0001] The invention relates to a pressure test device, in particular to a static pressure test device for a packaged mechanical seal, which belongs to the technical field of packaged mechanical seal processing. Background technique [0002] Cartridge mechanical seals are generally composed of glands, shaft sleeves, seal rings, O-rings, springs and other parts. Each set of cartridges must be tested for static pressure before leaving the factory. Because the shaft diameters of cartridge mechanical seals are different , the mechanical seal of each specification must have a corresponding chamber and chassis, each test needs to link the cartridge mechanical seal with the chamber and chassis, and manually lock the bolts to ensure uniform force, and then carry out Pressure test; the existing pressure test device needs to make a corresponding cavity and a corresponding chassis according to the specifications of the cartridge mechanical seal, resulting in material wa...
