Reaction kettle is one of the key equipment in chemical, chemical fiber, petrochemical, pharmaceutical and other production processes. Compared with pumps and other rotating machinery, it has unique use conditions and operating characteristics. Therefore, although the mechanism of kettle mechanical seal is the same as that of pump mechanical seal, kettle machinery has its own system due to its particularity. Reaction kettle generally consists of kettle body, agitator, transmission mechanism and shaft seal

I CDMSC ™— The integral design of the canned double end integral static ring compensated convection seal ring improves the stability of the seal ring under high temperature and pressure conditions, prolongs the service life of the seal under such conditions. The driving contact area of the seal ring is large, preventing damage to the seal ring when the equipment starts or stops under viscous liquid conditions. The internal clearance is large, maximizing the density

The face morphology of mechanical seal has a significant impact on the seal performance and life. The main characteristics of the surface morphology of the actual seal ring are that the local part has randomness, while the overall part has statistical laws, which are generally characterized by rental accuracy and correlation length. To solve this problem, this paper simulates the face topography of mechanical seals based on the stochastic process and time series theory

204 What is the relationship between mechanical seal and evacuation? According to the statistics of China's petrochemical industry, more than 80% of centrifugal pumps use mechanical seals. Due to the different working conditions of the mechanical seals of centrifugal pumps, material leakage often occurs in the process of conveying materials, polluting the environment and wasting energy. Mechanical seal is one of the main wearing parts of centrifugal pump, and pump failure

Use of mechanical seal for kettle 1. Before normal use, operate under normal pressure, and observe whether the temperature rise of the sealing part is normal and whether there is leakage. If there is slight leakage, run in for a period of time to make the end face fit more evenly until the leakage gradually reduces to normal. If the leakage does not decrease after 1-3 hours of operation, stop the machine for inspection. 2. Main

204 How can the mechanical seal manufacturer tell you to play a sealing role? 1. Push type mechanical seal and non push type mechanical seal Push type mechanical seal refers to the mechanical seal that the auxiliary seal is pushed mechanically along the shaft or shaft sleeve to compensate for the wear of the sealing surface, which is usually referred to as spring pressed mechanical seal. Non push type mechanical seal is used for auxiliary sealing

1. Preface: Kettle machinery is an important system equipment for industrial production. If leakage occurs in the production and application phase, it will have a negative impact on product quality, and will also emit toxic, explosive and flammable dangerous gases, posing a significant hazard to the ecological environment and the plant system itself. If the kettle machinery is overhauled for many times, the materials need to be transferred out and necessary

What are the key points of using mechanical seals for kettles? In the pump parts, mechanical seal is a very important part, and mechanical seal is also a vulnerable part. If the mechanical seal is damaged, the pump body will leak. If a direct coupled pump is used, the motor will be damaged once the medium in the pump body penetrates into the motor. Therefore, the quality of mechanical seals is crucial. want

204 What are some mistakes that should be paid attention to during the maintenance of mechanical seals? 1. The greater the spring compression, the better the sealing effect. In fact, the spring compression is too large, which can lead to rapid wear and instant burning of the friction pair; Excessive compression makes the spring lose the ability to adjust the end face of the moving ring, leading to seal failure. 2. The tighter the dynamic ring seal diagram, the better. The driving ring seal ring is too tight

204 What are the maintenance methods and precautions of mechanical seal manufacturers? Because the application environment of mechanical seal is very messy, and the seal structure is more complicated, the sealing degree of mechanical seal is very simple to be damaged, so it is very important to repair the mechanical seal. 1、 Precautions for disassembly of mechanical seal 1. Installation sequence of mechanical seal and disassembly of pump mechanical seal

How should the joint mechanical seal manufacturer of synthetic polymer sealing material construct well? Before the joint construction of synthetic polymer sealing material, the adhesive body shall be inspected, the materials and tools shall be prepared, the construction temperature shall be selected, and the joint shall be treated. The coating of base course treatment agent should first be accurately proportioned and evenly mixed. When multi-component mechanical sealing base course treatment agent is used
