Gear pump mechanical seal selection method Mechanical seal is a sophisticated, complex structure of the mechanical basis of one of the components, all kinds of synthetic reactor, turbine compressor, submersible motor and other equipment, the key components, so be careful Type and use. A. Mechanical seal According to the working conditions and the nature of the media, there are high temperature, low temperature mechanical seal, high pressure, corrosion resistant mechanical seal, mechanical seal resistant to particulate media and easy to vaporize light hydrocarbon medium mechanical seal should be According to different uses to choose different types of mechanical seals and materials. Selection of the main parameters are: sealed chamber pressure (MPA), fluid temperature (℃), operating speed (M / S), fluid properties and installation of effective space pump seal. B. gear pump selection of the basic principles are: 1. According to the sealed chamber pressure, determine the seal structure using balanced or unbalanced, single-ended or double-ended and so on. 2. According to the speed of work, to determine the use of rotary or static, hydrodynamic or non-contact type. 3. According to the temperature and fluid properties, determine the friction pair and auxiliary sealing material, and the correct choice of lubrication, washing, insulation, cooling and other mechanical seal cycle protection system. 4. According to the installation of effective space sealed to determine the use of multi-spring or single spring or wave spring, built-in or external. (Gear pump mechanical seal selection)
Gas Cylinder
A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.Our cylinders are divided into double wire port and hexagonal valve. Double wire port is mainly exported to Middle East countries, while hexagonal valve is mainly exported to Nigeria.According to the capacity, we have hexagon valves in 3kg, 5kg, 6kg, 10kg and 12.5kg.We have one kilogram, two kilogram, three kilogram, five kilogram double filament
