Tail shaft mechanical seal pressure test device

Abstract

The invention discloses a tail shaft mechanical seal pressure test device. The invention relates to the technical field of mechanical speed measurement, and the objective of the invention is to solveproblems that it is inconvenient for an existing sealing detection device to carry out dynamic sealing detection on the tail shaft and the sealing bearing, which causes errors to detection results andduring detection, manual fixation consumes time and labor. According to the invention, the test device comprises a box body; the top of the box body is fixedly connected with two supporting rods. A top plate is welded to the top ends of the supporting rods, a driving motor is arranged below the top plate, lifting mechanisms are arranged on the two sides of the driving motor, an output shaft of the driving motor is fixedly connected with a disc, a second gear is fixedly connected to the bottom of the disc, and sealing mechanisms fixedly connected with the lifting mechanisms are arranged on thetwo sides of the second gear. According to the device, automatic fixing is facilitated, good sealing performance is achieved during fixing, the detection accuracy is guaranteed, meanwhile, the sealing effect of the stern shaft in the dynamic state can be observed conveniently, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical speed measurement, in particular to a pressure test device for a mechanical seal of a stern shaft. Background technique [0002] The stern shaft is also called the tail shaft. The stern shaft is the last shaft in the shaft system. The flange at the head end is connected with the flange of the intermediate shaft with tight fitting bolts; the tail end is conical and used to install the propeller. The stern shaft is forged with high quality carbon steel. [0003] Since the stern shaft is installed at the tail end of the ship to install the propeller, it needs to be rotated, and the stern shaft machinery of the ship includes structures such as the stern shaft, sealed bearings and propellers. The sealed bearing is mainly used to support and fix the stern shaft to reduce the The wear and tear of the shaft rotation also plays a role in sealing the inside and outside of the ship. However, when the st...
