Water pump bearing manufacturers talk about the installation of water pump bearings

Water pump bearings must be installed under dry and clean environmental conditions. Before installation, you should carefully check the processing quality of the mating surface of the shaft and the housing, the end surface of the shoulder, the groove and the connecting surface. All mating surfaces must be carefully removed from burrs.

      Before installing the water pump bearing, clean it with gasoline or kerosene, and use it after it is dry, and ensure good lubrication. Generally, grease lubrication is used, but oil lubrication can also be used. The double-row tapered roller bearing with sealed structure and the water pump shaft bearing have been filled with grease, and the user can use it directly without cleaning.

      During installation, equal pressure must be applied to the circumference of the end face of the ferrule, and the ferrule must be pressed in. Do not use a hammer or other tools to directly knock the end face of the shaft water pump to avoid damage to the bearing. In the case of small interference, the end face of the bearing ring can be pressed with a sleeve at room temperature, and the sleeve can be hit with a hammer, and the ring can be pressed in evenly through the sleeve. If installed in large quantities, hydraulic presses can be used. When pressing, make sure that the end face of the outer ring and the shoulder end face of the housing, and the end face of the inner ring and the shaft shoulder end face are pressed tightly, and no gap is allowed.

      The clearance of the single row tapered roller bearing should be adjusted at the end of the installation. The clearance value should be specifically determined according to different operating conditions and the size of the matching interference. If necessary, it should be tested to determine. The double-row tapered roller bearings and the water pump shaft bearing have been adjusted in clearance before leaving the factory, so there is no need to adjust them during installation.

     After the bearing is installed, a rotation test should be carried out. First, it is used for the rotating shaft or the bearing box. If there is no abnormality, it will run at a low speed without load with power, and then gradually increase the rotation speed and load depending on the operating conditions, and detect noise, vibration and temperature. If an abnormality is found, the operation should be stopped and checked. It can be used normally only after normal operation test!
