1. In the pipeline operation of the multi functional
water pump control valve does not appear water or water shortage problem.
The possible reason is: the hydraulic control valve to control the
pump may exist without water or do not fill, which requires to open the valve we, to add to the diversion and filled with water; and, perhaps is the bottom end of the valve due to the existence of the long-term operation of the rusty condition. It can also is the internal sealing performance is not good, or a certain parts loose; there may be installed the wrong distances, installed too close to affect performance; if this valve operation for a long time, is also likely to be caused by wear.
2. Multifunctional
pump control valve in operation there abnormal sound: there may be multi functional water pump control valve is runtime generated under the conditions of unbalanced the vibration or abnormal noise, and may is a screw loose or gasket is too thin, there may be internal transport run slide caused by poor.
3. Bearing in operation have a fever situation: is generally poor quality of lubricating oil, or in the lubricating oil mixed with water, so that the rotation of the affected, and may pull belt too tight in the operation effect and so on.
4. In the running of the engine run black smoke or do not move with multifunctional pump control valve: is this possible reasons: multifunctional pump control valve speed more than the rated speed, or hydraulic control valve lift low multifunctional pump control valve rated speed of lift is more, multifunctional pump control valve shaft power is increased, or is running water contains some impurities, which affects the performance of equipment operation.
