Device for eliminating mounting error of floating sealing ring

Abstract

The device for eliminating installation errors of floating seal rings of the present invention belongs to the field of installation of floating seal rings; the technical problem to be solved is to provide a device for eliminating installation errors of floating seal rings, and use a pressure applying device to uniformly Apply pressure, use external force to customerize the elastic pre-tightening force of the floating seal ring, and accurately press the floating seal ring into the position to be installed; the technical solution adopted to solve this technical problem is: the device for eliminating the installation error of the floating seal ring, including the pressure applying device , the lower pressure body and the floating seal ring, the lower pressure body is located on the upper surface of the end cover of the floating seal ring to be installed, the pressure applying device is located on the upper surface of the lower pressure body and provides pressure to the end cover for the lower pressure body, the pressure applying device It includes a pressurized cylinder and a positioning leg. The positioning leg is set on the outer surface of the positioning end of the pressurized cylinder. The lower end of the positioning leg is provided with a strong magnetic device. The positioning leg is fixed on the extension of the end cover through the strong magnetic device. The pressurized cylinder passes through The positioning leg is fixed and limited.

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
