1. Determine the direction of rotation. Connects the pump and the motor before must be individually to determine the motor rotation direction, because of the slight reversal will also caused the accident, the pump and motor damage, so before the start must determine that the pump direction of rotation, rotation direction and rotation direction is clockwise.
2. Bearing oil. To lubricate the bearing box to ensure that the amount of oil, to meet the requirements, the oil too much or too little will heat the bearing, bearing service life.
3. Ensure cooling and cooling. To add cooling water cooling water jacket of the packing box of circulating flow.
4. Turning. Turn the coupling by hand, check whether the rotation is smooth, smooth, there is no blocking phenomenon.
