Unveiling the advanced technology behind the RJ Mechanical Vacuum Pump, this oil-free marvel comprises a powerful pump head, a robust motor, and a durable base. The pump head is a sophisticated assembly featuring dynamic and fixed scrolls, a precision-engineered crankshaft, high-quality seals, an efficient cooling fan, and a sturdy housing. The scrolls, skillfully crafted in an involute curve design, boast a circular plane with one or more spiral walls extending outward. Together, the fixed and dynamic scrolls form a highly efficient scroll pair, which is at the heart of the oil-free scroll vacuum pump's basic pumping mechanism. As they operate in harmony, these scrolls maintain a non-contact relationship, relying on intricate relative motion to generate shrinking crescent-shaped chambers for suction and compression. This cyclical process of suction, compression, and exhaust draws gas in from the suction port and expels it through the exhaust port, masterfully achieving vacuum pumping in the designated chamber.
