Problems solved by technology

The working environment medium of the mechanical seal device is high temperature, high pressure steam or hot water. The spring and rubber auxiliary sealing ring of the mechanical seal device are soaked and exposed to the medium for a long time. Due to the influence of scaling and temperature, the spring force is uneven and prone to jamming. , breakage, rubber auxiliary

Abstract

The invention discloses a mechanical sealing device of a vapour-liquid full flow screw power machine, which is composed of a moving ring (1), a corrugated pipe compensation stationary ring (2) and a spring compensation radial stationary ring (3) with double end surfaces, wherein, the moving ring (1) is installed on a rotor spindle (5) or a shaft sleeve (51); the stationary ring (2) is arranged on the left side of the moving ring (1), and the spring compensation radial stationary ring (3) is arranged on the right side of the moving ring (1); and the mechanical sealing mechanism with axial double end surfaces and radial double end surfaces is formed. The mechanical sealing device has simple structure, long service life and reliable operation, improves the operation reliability of a friction sealing end surface; and the spring compensation radial stationary ring (3) with the double end surfaces fully prevents leaked medium from mixing with lubricating oil to cause emulsification.

Description

technical field [0001] The present invention relates to a mechanical device converted into power by pressurized steam or liquid or a vapor-liquid mixed medium, that is, a vapor-liquid full-flow screw power machine, especially its mechanical seal device. Background technique [0002] The vapor-liquid full-flow screw power machine consists of a casing, a pair of screw rotors that rotate and cooperate with each other, a mechanical seal, a synchronous gear, a low-pressure end seat, and a high-pressure end seat. Synchronous gears, bearings, and mechanical seals are respectively installed in low-pressure end seats and high-pressure end seats, and steam inlet and outlet pipes are respectively opened at both ends of the casing. High-pressure steam enters from the steam inlet, acts on the rotation of the helical rotor, and then discharges from the steam outlet, converting the medium pressure into power output. [0003] The mechanical seal is the key component and the only wearing pa...
