Double Mechanical Seal Barrier Fluids and How They Work
Dual mechanical seals are used in the process of electrical engineering. They are an essential component of any machine since the mechanical seal prevents the fluid from leaking from inside the machine, thus avoiding any external damage. Machines such as pumping equipment are commonly known to have
Features of Water Pump Mechanical Seal
Mechanical seal is a device used to solve the seal between the rotating shaft and the body. It is composed of at least a pair of end faces perpendicular to the axis of rotation under the action of the fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the auxi
How to Install the Double Mechanical Seal
The double-end mechanical seal has the characteristics of short seal axial size and compact structure, so it is especially suitable for occasions where the axial size is restricted. Due to the complex structure of the double mechanical seal, high technical requirements, and strict sealing performanc
Basic Knowledge of Metal Bellows Mechanical Seal
The metal bellows mechanical seal is a single-end, balanced, and arbitrary-rotation metal bellows seal. Since the moving ring O-ring and flexible graphite ring can not compensate, there is no resistance to the movement of the bellows, which is suitable for high temperature and high viscosity media.
Performance Requirements and Technical Requirements of Mechanical Seals
This requirement applies to centrifugal pumps and other similar rotary mechanical seals. The working parameters are: working pressure is 0---1.5691MPa (referring to the actual pressure in the sealed cavity); working temperature is -20--80℃ (referring to the actual internal temperature of the sealed
What is Double Mechanical Seals
Compared with the single end face mechanical seal, the double mechanical seal has a better sealing performance. It is suitable for the sealing of strong corrosion, high temperature, suspended particles and fiber media, gas media, flammable, explosive, volatile, and low viscosity media, and high vacu
Quality Inspection Process of Mechanical Seal
The mechanical seal is a sealing device composed of two sealing elements (stationary ring and moving ring) perpendicular to the shaft, smooth and flat surfaces attached to each other, and relative rotation. It relies on the pressure of the sealing medium to generate the appropriate pressing force on
Reasons and analysis of mechanical seal failure
The failure of mechanical seals is generally known to people after abnormal leakage, abnormal wear, abnormal torque and other phenomena appear. The reasons for the failure are rough as follows:Four main reasons1. The sealing surface is openWhen repairing mechanical seals, 85% of seal failures are no
Mechanical Seals
Mechanical seals are one of the basic mechanical components with precision and complex structure. They are the key components of various pumps, reaction synthesis kettles, turbo compressors, submersible motors, and other equipment. Its sealing performance and service life depend on many factors, suc

Before installation, check whether the parts of the whole machine are intact, the fasteners shoul
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
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
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
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
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
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
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
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
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
