H-150 Slide Valve Vacuum Pump Installation Instructions 1 The pump should be installed in a dry, well-ventilated and clean place with an ambient temperature of 5-40 ° C.
2. Pump should be installed on the basis of concrete, should be left around 5-10 cm of the trench, so as to avoid water, oil, water contaminated sites. There should be left around the maintenance, repair, disassembly of the space.
3. Install the pump should be calibrated level, and then tighten with anchor screws. Pump to System Connections The tubing transitions to a metal bellows, rubber tube or spring-loaded plastic hose to improve joint sealing and reduce vibration.
4 according to motor signs and then connect the power supply, and ground lines and the appropriate capacity of the fuse, fitted with the motor corresponding to the thermal relay, you can protect the motor. The direction of rotation of the motor should coincide with the direction of the arrow shown by the pump. At this point pump suction port should be inhaled, confirmed correct before being put into normal use. The pump can not be continuously inverted, so as not to damage the pump and pump down the oil pollution system.
5 according to the provisions of the mark and the amount of water installed into the water inlet pipe should be installed on the valve to regulate the amount of cooling water.
6. Mineral oil vapor hinder health, there will be exhaust in the process of oil mist discharge, open the town or higher inlet pressure more, should be equipped with mist eliminator, and then exhaust pipe from the workplace. Exhaust pipe mouth should be down, so as to avoid rainwater, pipe diameter should be standard, small will increase the resistance.
7. Intake pipe diameter should not be less than φ100, should be short and elbow less to reduce the loss of pumping.
8. In order to stop the pump is pumping system was isolated, the pump inlet pipe should be installed vacuum cut-off valve. In order to slow down the return pump when the pump stopped, there is a manual bleed valve between the pump port and the shut-off valve, if the pumping system allows the shut-off valve fully open, you can choose vacuum cut-off band deflation solenoid valve. With this valve can be installed in the pump flange, should be cross-loaded.
If there is no start-up difficulties, the pump port can be sealed start, or can be drawn to start the atmosphere. With the bleed valve, the pump can be stopped under vacuum and then the air is pumped into the pump.
