1.轻负荷能提升,额定负荷不能提升或提升缓慢 (1)在提升状态时,农具无抖动,人为地用外力抬起农具使其提升后,踩下离合器,农具均能保持在提升位置。这表明,液压油缸和分配器工作正常。农具不能提升和提升缓慢的其他原因有:①传动系油面过低。②气温低,齿轮油粘度大。③油泵吸油滤网部分堵塞。④进油管连接螺栓松动或密封圈老化,造成进油路密封不严,吸入空气。⑤油泵的前、后盖与泵体平面之间误装上纸垫,使油泵两轴套外端面被密封环隔成的高压区与低压区连通;或油泵轴套端面磨损,压不实密封圈,造成内漏。 (2)在提升状态时,农具有抖动,切断油泵传递动力后,农具在自重作用下静沉降,这主要是分配器或油
1. Light load can be increased, the rated load can not be improved or slowed down (1) In raising state, no jitter tools, artificially lifted the tools to enhance the use of external force, depressing the clutch, farm tools can be maintained in a raised position. This indicates that the hydraulic ram and distributor are working properly. Other reasons why farm implements can not be promoted and slowed are as follows: ① The driveline oil surface is too low. ② low temperature, gear oil viscosity. ③ pump suction filter partially blocked. ④ into the connecting pipe loose bolts or seal aging, resulting in strict sealing into the oil, inhale the air. ⑤ pump before and after the cover and the plane between the plane mistakenly installed on the paper pad, so that the outer end of the oil pump bushing seal ring is divided into high-pressure zone and the low-pressure zone connectivity; or oil pump sleeve end wear, pressure unreliable seal Circle, resulting in internal leakage. (2) In the state of ascension, the agricultural tools have the jitter, cut off the power transmission pump, the static self-weight under the action of settlement, which is mainly distributor or oil
