Problems solved by technology

[0004] 1. Although the packing seal is easy to assemble and easy to replace, it also has a large amount of leakage, a short service life, is not suitable for working media containing solid particles, has large frictional resistance, consumes high shaft power, and is not suitable for high pressure and seal leakage. Occasions with higher requirements; and with the increasing emphasis on environmental protection, the packing seal on the rotor pump should have been gradually replaced by mechanical seals with superior sealing performance and long service life
[0005] 2. The mechanical seal has the advantages of small leakage, long service life, energy saving and environmental protection, and simple maintenance. However, due to the structural characteristics of the lobe rotor pump, the size of the mechanical seal installation cavity is small, and the general-purpose mechanical seal cannot be used directly, and The existing mechanical seal still has many parts and difficult installation, so it must be customized and developed. At the same time, because the rotary lobe pump has a wide range of applications, a large variety of conveying media, and very complicated application conditions, this pump is used in the entire machine pump The industry accounted for a small share, which brought great difficulties to the research and development of mechanical seals, resulting in the current performance and installation of mechanical seals have affected the development of the rotary lobe pump industry

Abstract

The invention discloses a cartridge mechanical seal for an industrial cam rotor pump. The cartridge mechanical seal comprises a shaft sleeve, wherein a moving ring component, a static ring component and a static ring component mounting seat sleeve the shaft sleeve, and the tail part of the moving ring component is hermetically assembled on a step ring at one end of the shaft sleeve; a first mounting groove is arranged in one end of the static ring component mounting seat, and the tail end of the static ring component is hermetically assembled in the first mounting groove; a compensation component is arranged between the tail end of the static ring component and the bottom of the first mounting groove; a second mounting groove is arranged in the other end of the static ring component mounting seat, an oil seal component is assembled in the second mounting groove, and an inner ring of the oil seal component is in sealing fit with the outer side wall of the shaft sleeve; and a driving ring sleeves the other end of the shaft sleeve, and a stop collar is arranged between the driving ring and the oil seal component. The cartridge mechanical seal for the industrial cam rotor pump is convenient to install and maintain, stable in performance and wide in application range.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a cartridge mechanical seal for industrial cam rotor pumps. Background technique [0002] Cam rotor pump is a relatively advanced fluid equipment. Compared with conventional rotor pump equipment, it has strong wear resistance, better self-priming capacity, high lift capacity, firmness, reliability, and is not suitable for clogging. It is suitable for various viscosities or The advantages of working conditions containing particulate matter are highly recognized by the market, and the application is becoming more and more extensive. As one of the important components of the rotary lobe pump, the shaft seal is a sealing device to prevent leakage between the pump shaft and the pump body. With the development of equipment and people's increasing emphasis on environmental protection, the sealing ability of the shaft seal and the length of service life have become one of the i...
