Center to attract station center to attract mainly by vacuum pump station, vacuum solenoid valves, vacuum valve, vacuum tank, automatic control cabinet and other components. According to the relevant provisions of the YY / T0186-94, gas consumption for each attract terminal 30L / min center to attract, according to the general ward, emergency room and other wards while using 20 percent of the price of suction, operating room utilization 100% calculate the amount.

There should be a manual pump coupling plate car inspection, turn the motor and pump should be light and flexible, no abnormal sound; 2, should check vacuum pipe and valves and other accessories, and should ensure diameter pipelines. Vacuum pump should be short and straight exhaust pipes, pipe diameter should be no partial reduced.
