Device for eliminating mounting error of floating sealing ring

Abstract

The invention discloses a device for eliminating the mounting error of a floating sealing ring, and belongs to the field of floating sealing ring mounting. In order to achieve the technical aim, the device for eliminating the mounting error of the floating sealing ring is provided, a pressurizing device is used for evenly pressurizing an end cover above the floating sealing ring, external force is utilized for overcoming the elastic pretightening force of the floating sealing ring, and the floating sealing ring is accurately pressed into a position to be mounted. According to the technical scheme for achieving the technical aim, the device for eliminating the mounting error of the floating sealing ring comprises the pressurizing device, a pressing body and the floating sealing ring; the pressing body is located on the upper surface of the end cover of the floating sealing ring to be mounted; the pressurizing device is located on the upper surface of the pressing body and provides pressure towards the end cover for the pressing body; the pressurizing device comprises a pressurizing cylinder and locating legs, the locating legs are arranged on the outer surface of the locating end of the pressurizing cylinder, and strong magnetic devices are arranged at the lower ends of the locating legs; and the locating legs are fixed to an extensional fixture of the end cover through the strong magnetic devices, and the pressurizing cylinder is limited by being fixed by the locating legs.

Description

technical field [0001] The invention discloses a device for eliminating installation errors of floating seal rings, belonging to the technical field of installation of floating seal rings. Background technique [0002] In the modern industry, the floating seal ring is a very important part of the machine, and it is also an indispensable item. The floating seal ring has a better sealing effect than the ordinary seal ring. Similarly, the floating seal ring is a consumable , Damage often occurs during use. Therefore, in order to ensure the normal operation of the machine, if the floating seal ring is found to be damaged during use, it must be replaced. Since the floating seal ring plays a sealing role, the installation accuracy The above requirements are relatively high. Only correct installation and accurate installation can ensure the use of the floating seal ring and the normal operation of the mechanical energy. [0003] However, the floating seal ring is a part with exter...

Problems solved by technology

[0003] However, the floating seal ring is a part with external pre-tightening force, so it is troublesome to install. When installing the floating seal ring, in order to make the floating seal ring snap into the floating seal seat, the floating seal is often manually screwed with tools such as a screwdriver. The edge of the ring is pressed into the floating seal seat, so that it is easy to make the floating seal ring deviate from the original position. At the same time, some materials of the floating seal ring are relatively brittle. During the process of pressing, the floating seal ring is easy to be damaged, or not flat Smooth, so it is easy to affect the accuracy of the seal, increase the friction of the floating seal ring, thereby reducing the service life, increasing the number of replacements and manpower
