H - 150 sliding pneumatic valve type vacuum pump installation considerations ( 1)

。 Pump should be installed in a dry, well ventilated, clean place, environmental temperature should be in -
° C. The pump shall be installed on the concrete foundation trench, - shall be maintained Cm, so open water, oil, water area. Four weeks by maintenance, repairs, dismantling space.
。 The pump installation should calibration level, and then screw down the screws feet of space. Metal corrugated pipe of pump and piping system connection, rubber or plastic pipe and lining spring transition, improve joint sealing and reduce vibration.
。 Powered by a motor then, signs, and with proper grounding line fuse capacity, with the proper thermal relay is installed in the motor protection. Direction of rotation of the motor and pump should be according to the direction of arrow. At this point, should be suction pump, can be put into normal use after confirmation. Discontinuous reverse in order to avoid damage to pump and pump system under the oil pollution.
。 Through the label, then put water pipes, cooling water inlet pneumatic valve should be installed to adjust.
。 Mineral oil steam unhealthy, will exhaust oil mist in the process of discharge, higher inlet pressure town or more, should install mist eliminator, and then work from exhaust gas. I should be the next exhaust pipe, to prevent rain water from entering the pipe diameter should be standard, small resistance.
。 Entry is not less than pipe diameter phi, elbow is shorter, less to reduce pumping losses.
。 Due to stop the pump, the pump system and the pump is cut off, from the closed water inlet manifold vacuum pneumatic valve should be installed. Slow oil pump station, when I come back between the ports of the pneumatic valve, pump, pneumatic valve with manual release, if started pumping system allows pneumatic valve fully open, you can use a vacuum of bleeding solenoid pneumatic valve within a time limit. With this pneumatic valve can be installed in the pump flange shall be installed level.
if you don't start, start pump inlet can be sealed, otherwise, they began to smoke the atmosphere. Equipped with the release of pneumatic valve, it can stop the vacuum pump, then enlarge to the gas station.
