YQ150型潜孔钻机自动部分是由两个行程开关控制的。它可以提高钻机的工作效率,降低工人的劳动强度、减少粉尘对操作人员的侵蚀。由于该开关装在滑架上,所处条件恶劣,又没有“三防”(防尘、防水、防油)装置,所以工作中粉尘、雨水、油污很容易破坏其绝缘介质,从而使其过早地损坏。长期工作证明:该部分是钻机电气元件的易损件,两、三个月要换一次,如遇雨季则寿命更短。开关损坏后,检修比较困难。因此,为了延长寿命,经 YQ150 DTH drilling rig part is automatically controlled by two travel switches. It can improve the working efficiency of the drilling rig, reduce the labor intensity of workers and reduce the dust erosion to the operators. Because the switch is mounted on the carriage, the conditions are harsh, there is no “three defenses” (dust, water, oil) device, so the work of dust, rain, oil is easy to destroy the insulating medium, so that Damaged early. Long-term proof of work: This part is wearing parts of drilling rig electrical components, two or three months to change, in case of rainy season, shorter life expectancy. After the switch is damaged, overhauling is more difficult. Therefore, in order to extend life expectancy
