我队使用六台JU-1000型钻机，经过三年左右的使用表明，钻机结构性能很好，比其它类型钻机故障较少，尤其在深孔使用，因有水冷装置，升降机优于其它类型的，工人同志喜欢用。但在液压系统方面，立轴操作阀无称重位置，而在下降位置下方又多了一个停位。JU-1000型钻机说明书图21液压操纵手柄位置图上注明，立轴操纵把有四个位置，即称重、上升、停止、下降，但是钻机标牌上只有上升、停止、下降三个位置，实际在下降位置下方又出来一个停止位置。
Our team uses six JU-1000 drilling rigs. After three years of use, it shows that the drilling rig has a very good structural performance and has fewer failures than other types of drilling rigs, especially in deep boreholes. Because of the water cooling device, the lift is superior to other types of Comrade workers like to use it. However, in terms of the hydraulic system, the vertical axis operation valve has no weighing position, and there is an additional parking position below the descending position. JU-1000 Drilling Rig Manual Figure 21 The location of the hydraulic joystick indicates that the vertical axis control handle has four positions, ie, weighing, rising, stopping, and descending. However, only the rising, stopping, and falling positions of the drilling rig are three positions. A stop position comes out below the descent position.
