去年九月,在黑龙江机械工业局主持下,PZQ-2.6二十四片重型缺口耙通过了鉴定。鉴定会代表认为,PZQ-2.6型重耙和PZQ-2.2重耙相比,有四个优点: 1.工作幅由2.2米增为2.6米,作业效率提高了18%。同时与东方红-75拖拉机配套较合理,提高了拖拉机功率的利用率。 2.采用内方孔、外球面、多层密封滚动轴承,与滑动轴承比较,每班可节省保养时间15分钟,节省黄油一公斤,提高了工时利用率。
Last September, under the auspices of the Bureau of Machinery Industry of Heilongjiang, PZQ-2.6 twenty-four heavy-duty notched harrows passed the appraisal. The delegates of the certification council considered that the PZQ-2.6 heavy harrow has four advantages over the heavy harrow PZQ-2.2: 1. Working width increased from 2.2 m to 2.6 m and work efficiency increased by 18%. At the same time with the East Red -75 tractor supporting a more reasonable and improve the utilization of tractor power. 2. The use of the inner hole, spherical, multi-layer sealed roller bearings, compared with the sliding bearings, each class can save maintenance time of 15 minutes, saving one kilogram of butter, increased utilization of working hours.
