LYB vertical submerged gear oil pump installation operation and disassembly sequence requirements description First, LYB vertical submerged gear oil pump installation requirements 1, the pump must be installed vertically on the liquid tank or the fixed bracket above the sink. 2. The suction port of the pump should be greater than 200mm from the bottom of the tank. LYB vertical submerged gear oil pump installation operation and disassembly sequence requirements description First, LYB vertical submerged gear oil pump installation requirements 1, the pump must be installed vertically on the liquid tank or the oil tank above the fixed bracket.
2. The suction port of the pump should be greater than 200mm from the bottom of the tank.
3. The outlet pipe of the pump must be equipped with a separate bracket. Botaibang does not allow its weight to fall directly on the pump body.
2. Disassembly sequence of LYB vertical submerged gear oil pump 1. Close the gate valve in the extrusion pipe and remove the coupling bolt or coupling pipe of the flange on the upper part of the discharge pipe. Remove a length of pipe, the length of which does not hinder the lifting of the pump.
2. Loosen the connecting bolts of the motor frame and the motor and hang the motor.
3. Remove the bolts of the pump body and the bracket and turn off the impeller.
4. Remove the middle bracket and pull down the coupling.
5. Remove the upper and lower bearing caps of the bearing body to check the bearing condition.
Third, LYB vertical submerged gear oil pump start, stop and run requirements 1, the motor before the installation, the power should be turned on to check the direction of rotation, must be consistent with the pump's specified direction of rotation.
2. Install the motor and turn the coupling. Check whether the pump shaft and the motor are concentric, whether the rotation is light or uneven, and then operate normally.
3. Close the outlet line valve and pressure gauge.
4. Start the motor and use the pressure gauge to open the outlet valve to the desired position.
5. For normal parking, the outlet valve should be closed first, then the motor should be stopped and the pressure gauge should be closed.
6, the bearing room should ensure sufficient grease, the bearing temperature rise should not be higher than 70 °C.
