AI Technical Summary
Existing laboratory circulating water vacuum pumps suffer from poor vacuuming performance due to water temperature rise during prolonged use, water tank contamination, and uncontrollable vacuum levels causing discoloration of sprayed materials, thus increasing workload.
The pump body is designed with a vacuum regulating valve and a vacuum gauge, and the water tank is equipped with an inlet valve and an outlet valve. The controllable vacuum and automatic water exchange are achieved through the combination of rubber hoses, retaining rings, threaded rods, nuts and gaskets, ensuring stable operation of the equipment.
It achieves precise control of vacuum level, avoids material spraying and discoloration, reduces manual operation, and ensures long-term stable operation of equipment and product quality.
