What is the common sense of mechanical seal selection-- 204 For the selection of mechanical seal elements, the working conditions shall be taken into consideration, so as to select the appropriate seal element form, material and installation structure. The working conditions to be considered generally include: temperature, pressure, medium. Its mechanical seals also need to be selected according to the characteristics of the equipment itself. About temperature, such as N

204 Technical requirements of mechanical seal The seal ring is the general name of dynamic ring and static ring (the same below), and is the main component of mechanical seal. To a great extent, seal ring determines the service performance and life of mechanical seal, so some requirements are put forward for it. There shall be enough strength and rigidity to avoid damage under working conditions (such as pressure, temperature and sliding speed), and the deformation shall be as small as possible

204 What are the types of mechanical seals introduced by mechanical seal manufacturers? 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 mechanical seal with auxiliary seal fixed on shaft, usually

204 The mechanical seal manufacturer analyzed the causes of the penetration. 1) Leakage caused by pressure. 1. Fault 1: Mechanical seal leakage caused by high pressure and pressure wave. Cause: The specific pressure of the spring and the total specific pressure are too large. When the pressure in the seal cavity exceeds 3MPa, the specific pressure of the seal face will be too large, the liquid film will be difficult to form, the seal face will be severely worn, and the heat generation will increase,

204 The mechanical seal manufacturer introduces basic knowledge 1. The basic concept of mechanical seal: mechanical seal is a device to prevent fluid leakage, which is composed of at least one pair of end faces perpendicular to the rotation axis, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and with the cooperation of auxiliary seals, to keep fit and relatively slide. The auxiliary seal of compensation ring is metal bellows

204 Mechanical seal manufacturer: Introduction to several cooling methods of mechanical seal! Flushing cooling: when the sealing medium temperature is high, the mechanical seal is usually purchased for flushing cooling. The inlet of flushing fluid is aligned with the friction surface. The purpose of flushing is to keep the temperature of the friction surface within a certain range and prevent the accumulation of impurities near the seal face. This is a common

204 The mechanical seal manufacturer teaches you how to prevent the leakage of the liquid pump! What should I do if the mechanical seal fluid pump leaks? Don't panic. The mechanical seal manufacturer will tell you how to solve the leakage. Let's start with the basic elements of the seal: the basic element of the seal, the mechanical seal, uses the principle of two planes running against each other to achieve the purpose of sealing. The rotary sealing surface is installed on the main part of the liquid pump

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

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
