Roots pumps and NYP high viscosity pump maintenance methods

Roots pumps and NYP high viscosity pump maintenance NYP high viscosity pump, Roots pump before the start of preparation, generally include the following steps: 1, after the new pump is installed, before starting, add 20-40 to the gear box Number of machine oil to the midline of the oil, minus 20-40 machine oil (or gear oil) to the middle of the oil, not too little. 2, hand wheel coupling to see if there is stuck phenomenon. 3, with preheating device type pump, the pump should be preheated to the required temperature before booting. 4, before starting the valve must be open in the export pipeline, and then open the inlet valve, or easy to damage the pump. 5, check whether the normal parts. During operation, always check the update to see the operating conditions, such as: hand crank coupling to see if there is jammed, the oil period according to the actual conditions of use and can meet the performance requirements and other considerations, check the sleeve Wear and tear, remember to stop before the outlet pipe valve, or easy to damage the pump. Maintenance methods include: 1, NYP high viscosity pump, Roots oil pump gear oil should be replaced once a year, gearbox oil recommended quarterly replacement. 2, found heavy oil pump, Roots pump leak serious, it should promptly check the seal damage. 3, after reassembly should be commissioned, usually 2 hours to air and change the oil twice, due to cleaning in the Roots pump will leave a certain amount of volatile, to be functioning properly, then put into normal work. 4, Start the motor, when Roots pump normal operation, open the outlet pressure gauge and import Roots pump, depending on the pressure showed its appropriate, and gradually open the valve, while checking the motor load conditions.
