• Introduction to the Pump Structure and Instructions for Use


    Schematic diagram of a cross-sectional structurePump three-dimensional structure diagramInstructions for use of water pump(1) The pump arrives at the engineering site after long-distance transportation. Before installation, check whether the parts of the whole machine are intact, the fasteners shoul Read More

  • The Double Mechanical Seal Drawing


    The double end face mechanical seal has two end face seals. If the primary seal fails, the secondary seal can still seal to prevent leakage. Compared with single mechanical seal, double acting mechanical seal has better sealing performance. It is suitable for the sealing of strong corrosion, high te Read More

  • How to Choose the Right Mechanical Seal


    In the selection of mechanical seals, working conditions must be considered, including the appropriate form and material of the seal, and the installation structure. The working conditions that need to be considered generally include: temperature, pressure, and medium. It also needs to consider the Read More

  • Brief Introduction of Mechanical Seal Structure and Analysis of Leakage Path


    The mechanical seal is a combined mechanism composed of a series of simple design elements. The sealing function is completed by two main sealing rings with flat surfaces to prevent leakage. One of the sealing rings rotates with the shaft, and the other sealing ring is fixed on the housing. In order Read More

  • Installation and Use Requirements of Mechanical Seal


    1. Mechanical seal requirements for machine accuracy (take mechanical seal for pump as an example)(1) The maximum radial runout tolerance of the shaft (or sleeve) where the mechanical seal is installed does not exceed 0.04~0.06MM.(2) The axial movement of the rotor does not exceed 0.3MM.(3) The maxi Read More

  • Working Conditions of Mechanical Pump Seals


    A mechanical water pump seals is a shaft sealing device for rotating machinery, such as centrifugal pumps, centrifuges, reactors, and compressors. Since the driveshaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the me Read More

  • The Common Sense of Anti-corrosion of Mechanical Seal


    For mechanical seals, its layout method, working environment and conditions are different and the degree of corrosion damage is also different. The common damage methods of mechanical seals such as PTFE seals and PTFE gaskets are mainly corrosion. Damage, thermal damage, and mechanical damage.1. Met Read More

  • Precautions for Disassembly and Assembly of Mechanical Seal


    A mechanical seal refers to a device that prevents fluid leakage by keeping at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to preve Read More

  • Precautions for Mechanical Seal Installation


    When installing1. Be very careful to avoid installation deviations during installation(1) The tightening of the gland should be carried out after the coupling is aligned, and the bolts should be evenly supported to prevent the end face of the gland from a deflection. Check each point with a feeler g Read More

  • Causes of Seal Failure


    The sealing surface itself will also provide signs of seal failure. For example, when vibration, there will be traces of wear on the transmission parts. If the traces are not obvious, it is generally caused by improper assembly. For the graphite ring (moving ring) of poor quality, there are more por Read More
