Installation of multi-stage pump mechanical seal by kettle mechanical seal manufacturer: 1. Sealing form: for static seal, there are usually only two forms: gasket and seal ring, and O-ring is the most widely used seal ring; For dynamic seals, centrifugal pumps rarely use packing seals, mainly mechanical seals. Mechanical seals can be divided into single end and double end, balanced type and unbalanced type, and the balanced type is suitable

1、 The pipeline part of the pipeline centrifugal pump is matched with some pipeline centrifugal pumps. Users think that this can improve the actual head. The actual head of the pump=total head~loss head. When the pump model is determined, the total head is certain; The loss head mainly comes from the pipeline resistance. The smaller the pipe diameter is, the greater the resistance is. Therefore, the greater the loss head is. So after reducing the pipe diameter, the actual lift of the pump

Measurement of end face wear of mechanical seal manufacturer 1. The weighing method is to measure the mass change before and after the friction pair ring test (operation) to determine the wear amount It is generally carried out on the balance, which is a simple and easy common method. 2. Length measurement method This method is through measuring}.: F The normal dimension change before and after the end face test of the friction pair is used to determine the wear amount, which generally requires a measurement benchmark

The mechanical seal manufacturer explains the maintenance problems and the preparations before starting 1. Fully check the mechanical seal, and whether the installation of auxiliary devices and pipelines is complete and meet the technical requirements. 2. Static pressure test shall be carried out before starting the mechanical seal to check whether there is leakage of the mechanical seal. If there are many leaks, find out the causes and try to eliminate them. If it is still invalid, it shall be disassembled, checked and reinstalled. one

The mechanical seal manufacturer introduces the flushing scheme of the seal for the purpose of directly injecting liquid into the high-pressure side of the double or single seal, which is called "flushing". Generally, pumps shall be flushed, especially light hydrocarbon pumps. 1. Flush to dissipate heat. The heat generated by the liquid seal must be controlled. This can be achieved by flushing the seal chamber with liquid to take away heat and control the temperature rise. 2. Lower the liquid temperature. stay

Technical conditions of kettle mechanical seal Only the kettle mechanical seal that meets the technical conditions is qualified. However, due to their too many models and different equipment, their requirements are different, and their production technologies are also different. So the quality of the products is different. The main purpose of formulating its technical conditions is to standardize the later production. Its technical conditions include:

Instructions for use of kettle mechanical seal 1. Mechanical seal (end face 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 cooperation of fluid pressure, elastic force of compensation mechanism and auxiliary seal, to keep sticking and relatively sliding. 2. Mechanical seal for kettle, applicable to all kinds of steel kettle, enamel kettle, glass lined kettle mixing shaft and

The mechanical seal manufacturer introduces advantages and disadvantages 1. Advantages (1) The structure is reliable, and the leakage can be limited to a small amount. As long as the surface roughness and straightness of the main sealing surface can meet the requirements, and as long as the wear resistance of the material is good, the mechanical seal can achieve a small amount of leakage, or even the leakage can not be seen by the naked eye. (2) Long life. In mechanical seals, the main wearing part is the end face of the seal friction pair,

The installation of mechanical seal for kettle shall ensure that the installation chamber is clean and free of any foreign matter. The shaft or sleeve matched with the mechanical seal shall be of correct size, smooth surface, good straightness, and free from burrs, sharp corners, nicks or deep scratches. Seal all holes in the seal chamber that are not used by the mechanical seal during operation. The end face of the seal chamber must be clean, smooth and perpendicular to the axis line. The two boxes of the horizontal split pump must

What is the difference between the mechanical seal for the agitator and the mechanical seal for the pump? Mechanical seal for agitator kettle and mechanical seal for pump are mechanical parts used to seal rotating shaft and static pump chamber. The sealed part is a cylindrical area, the shaft in the equipment rotates and penetrates inside and outside the equipment, and the body part is still and full of fluid medium inside. Driven by pressure difference, concentration difference, temperature difference, etc

Some key points of mechanical seal installation and disassembly There should be a layer of liquid film between the seal rings of mechanical seal, which has the following functions: 1. Support most of the water pressure load on the seal. 2. As a lubricant, reduce the friction heat generated by the seal ring. 3. Minimize rough contact to reduce wear rate. 4. As the heat transfer medium, transfer the direct area of the seal ring
