Magnesium metal equipment, metal calcium equipment, calcium, magnesium mechanical vacuum pump (magnesium metal reduction mechanical vacuum pump, vacuum unit) vacuum Pidgeon magnesium is necessary, mechanical vacuum pump Pidgeon magnesium refining, calcium necessary equipment , Which is used for metal magnesium (calcium) reduction tank vacuum reduction process Pidgeon method (also known as silicon thermal method), the use of mechanical vacuum pump, there are currently 3 medium-sized vacuum pump. Magnesium (calcium) mechanical vacuum pump program 1, Roots vacuum pump ZJP1200 2, Roots vacuum pump ZJP600 3, Slide valve vacuum pump H150 above for the reduction of magnesium metal components need to be composed of vacuum units are as follows: Category 1 configuration Roots vacuum pump ZJP1200 Sliding valve vacuum pump H150 form a vacuum unit to form a vacuum unit with a suction rate of 1200L / S. (Most domestic magnesium manufacturers use this configuration plus sliding valve vacuum pump H150 to do reduction tank pre-pumping) ZJP1200 / H150 vacuum unit main performance parameters: Ultimate vacuum: 0.1pa Extraction rate: 1200S / L Intake diameter: 250mm Exhaust port diameter: 80mm Motor power: 11KW + 15KW = 26KW Pre-pumping H150 Main performance parameters: Ultimate vacuum: 1pa Pumping rate: 150S / L Intake port diameter: 100mm Exhaust port diameter: 80mm Motor power: 15KW Magnesium ) Mechanical vacuum pump program Two Roots vacuum pump ZJP600 and slide valve vacuum pump H150 to form a vacuum unit to form a vacuum pumping rate 600L / S of the vacuum unit. (Most domestic magnesium manufacturers use this configuration plus sliding valve vacuum pump H150 to do reduction tank pre-pumping) ZJP600 / H150 vacuum unit main performance parameters: Ultimate vacuum: 0.1pa Extraction rate: 600S / L Intake diameter: 200mm Exhaust port diameter: 80mm Motor power: 7.5KW + 15KW = 22.5KW Pre-pumping H150 The main performance parameters: Ultimate vacuum: 1pa Extraction rate: 150S / L Inlet diameter: 100mm Exhaust diameter: 80mm Motor power: 15KW The vacuum Unit Features: Sliding Valve Pump It has the working pressure is high (105Pa), pumping capacity, in a harsh environment, continuous vacuum work, durability and other outstanding advantages, so it has a vacuum smelting work pressure high (105Pa) , Pumping capacity, can work in harsh environments, durable and other outstanding advantages; vacuum pumping unit without fluctuations, the vacuum rose fast and stable, magnesium reduction of good quality, so the vacuum unit is widely used by manufacturers of magnesium. The main components of the vacuum pump and material: Sliding valve pump advantages: One of the slide pump pumping vacuum part; guide rail, slide valve, eccentric and so is the main working parts for the slide valve pump; my company after years of research and development to improve the eccentric wheel molding. At the same time components are doing dynamic balance, oil seal for the high temperature fluorine rubber, the use of imported NSK Bearings. Roots vacuum pump advantages: vacuum unit Roots vacuum pump with a bypass valve, effectively solve the motor overload and cause the motor to burn out. Roots vacuum pump main components are: rotor, shaft, bushings, gears and so on. Gear material using 20GrMnTi, 45 # steel sleeve high-frequency sputtering process, the drive shaft with 45Gr. At the same time components are doing dynamic balance, oil seal for the high temperature fluorine rubber, the use of imported NSK Bearings. Part of the vacuum pump manufacturers, eccentric processing for the second or even three times combined molding process, some manufacturers slide valve pump H-150 with larger motor power, and increased user costs. More manufacturers, spare parts processing, their own factory assembly only machine, the entire vacuum unit modeling rough, while the unit rack is not the joint structure, noise, vibration, service life and performance greatly reduced.
