How to use engine water pump and maintenance measures

In the use and maintenance of the engine pump must pay attention to the following points:

Correct installation and installation, the gear pump gears and transmission gear should be closely integrated, belt-driven pump pump shaft and pulley should ensure that the concentricity of the provisions of the range, to prevent the engine speed increase or load caused by the water sloshing , Aggravate the wear and tear.

Correctly adjust the tightness of the belt Fan belt can not be adjusted too tight, otherwise it will increase the load on the pump bearing. If it is more than two belt drive, to ensure that a few old and new, length, tightness consistent with each other to prevent uneven belt tension, the pump is not balanced and premature damage.

Timely filling lubricants According to the instructions in the manual, timely filling of the pump bearing oil, the number of filling oil can not be too much or too little, to prevent premature bearing damage.

Do not plug the overflow hole Some pump shaft overflow hole, through the overflow hole to observe whether the water pump leaks. If the overflow hole blocked, the water pump leak into the bearing will affect the lubrication, causing premature bearing damage.

Do not be disassembled hard hit knocking repair pump, remove the pulley and pump bearings and other major parts of the application of special tools. If you hit the hard hard knock during installation, easy to cause bending deformation of the pump bearings, pump shaft shaft threaded slider or damage. Another impeller and pump shaft with tighter, unless necessary, generally do not disassemble.

Timely removal of the scale inside the pump Scale accumulation in the pump too much, will make the water pump pump capacity weakened, while the scale will corrode the pump parts, easy to premature failure of the pump.
