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

What should the mechanical seal manufacturer pay attention to before and after installation? Mechanical seal is a kind of mechanical equipment component requiring high precision. The service performance and service life of Tianjin mechanical seal are greatly related to the operating conditions, precision and seal installation of the host machine. Therefore, it is necessary to follow the requirements before, during and after the installation of mechanical seal, otherwise it is easy to affect

What are the structural characteristics of the mechanical seal for kettle? In terms of sealing principle, the machinery used for kettle and discharge chute is the same as that used for pump, but the mechanical seals used for pump have the same operating conditions and operating technology. Therefore, the requirements for seal structure design and sealing system are different from those used for pump, and have their own characteristics: 1. Radial vibration and axial displacement of mixing shaft

The mechanical seal manufacturer tells you the corrosion type and protection method of the mechanical seal. The mechanical seal is often damaged. The common damage forms are mainly corrosion damage, thermal damage and mechanical damage. The corrosion damage of mechanical seal knowledge is more harmful. Due to the special structure of mechanical seal and different working environment and conditions, the forms of corrosion damage are also diverse.

204 How to remove the mechanical seal for maintenance After removing the mechanical seal, first check the pump body where the organic seal is installed, and the following requirements must be met: 1. The maximum shaft bending is ≤ 0.05mm, and the axial displacement is ≤ 0.05mm. 2. The runout at the sealing ring of the moving ring is ≤ 0.01mm. 3. The surface roughness of the shaft or shaft sleeve at the installation part of the mechanical seal is 1.6 μ m. And stationary ring

How to repair the mechanical seal used by the mechanical seal manufacturer? The maintenance mechanical seal of mechanical seal is a sealing equipment composed of two sealing elements (static ring and dynamic ring) perpendicular to the shaft, bright, and the flat and straight appearance of light mechanical seal for pump, which fit each other and roll relatively. It depends on the pressure of the sealing medium to produce proper results on the touch surface (end face) of the rotating rotating ring and stationary ring

The sealing equipment of the reaction kettle The sealing equipment used in the reaction kettle is a dynamic sealing structure, which mainly includes two types: packing seal and mechanical seal. The mechanical seal for kettle is compared with the stuffing box seal. The seal is firm, and the mechanical seal will not leak or rarely leak during a long service period. Clean, no dead corner, can avoid contamination of miscellaneous bacteria.
