The ZJQ series air-cooled Roots vacuum pump is an enhanced evolution of the original ZJ series. By incorporating an advanced bypass gas cooling system, this series ensures that both the rotor and the pump chamber remain optimally cooled, effectively avoiding high temperature concerns even under substantial pressure differentials. Typically, heat exchangers are strategically positioned either at the exhaust port or within the pump's return line. The expelled gas undergoes cooling via the heat exchanger, where it is then reintroduced into the pump chamber from both ends of the pump body. This innovative design efficiently cools the rotor and pump chamber, maintaining exceptional pumping performance. This versatile pump is not only capable of standalone operation but also integrates seamlessly in series with various other vacuum pumps, including liquid ring, reciprocating, and slide valve vacuum pumps. Thus, it achieves superior vacuum levels and enhanced pumping velocities, catering to diverse industrial needs while significantly optimizing energy efficiency.
· Capable of solo operation, this pump achieves an impressive working vacuum degree, reaching direct exhaust levels of 15-20 kPa with ease.
· When synergistically connected in series with a front pump, it forms a highly efficient Roots unit, offering versatile ratios that reliably achieve5 ~10-2 Pa, delivering outstanding energy-saving benefits.
· Offering a frictionless design, the pump's components require no lubrication, ensuring an oil-free chamber and achieving an exceptionally clean vacuum environment.
· Featuring a sophisticated three-leaf plum blossom line structure alongside precision machining, it promises smooth, quiet operation without compromise.
· Its air extraction capabilities, noise reduction, and reduced vibration outperform traditional two-blade rotor models, marking a significant performance leap.
· The pump's vertical gas flow promotes the efficient discharge of dust and condensate, enhancing the quality of the vacuumed gas.
· With a broad application scope, the pump excels even under elevated inlet pressures, making it a versatile choice for many industrial sectors.
· The motor power is variable, necessitating a precise calculation of maximum pressure differentials during actual operation to appropriately configure motor power to process conditions.
