Application and function of vacuum pump

Vacuum pump is a rotary variable displacement vacuum pump, which can only be used with the cooperation of the front pump. It has a large pumping speed in a wide pressure range and is insensitive to dust and water vapor in the pumped gas. Widely used in metallurgy, chemical industry, food, electronic coatings and other industries. Vacuum pumps are widely classified, There are mainly WLW series vertical oil-free vacuum pumps, W reciprocating vacuum pumps, 2X, 2XZ rotary vane vacuum pumps, ZJ, ZJH Roots vacuum pumps (ZJH is a patented product), 2SK, SK water ring vacuum pumps, 2BV, 2BA water ring vacuum pumps, H, 2H slide valve vacuum pumps, TLZ vacuum pumps, SL Roots blowers, JZJHX roots rotary vane vacuum units, JZJHS roots water ring vacuum units, JZJHWLW vertical oil-free vacuum unit, jzp Roots water jet vacuum unit and JZJHBA vacuum pump are widely used in plastic machinery, pesticide chemical industry, dye chemical industry, brick and tile machinery, low-temperature equipment, papermaking machinery, pharmaceutical chemical industry, food machinery, industrial electric furnace, electronic industry, vacuum equipment, chemical fertilizer, metallurgy, petroleum, mining, foundation treatment and other fields.
