What To Do If The Power Head Of A Rotary Drilling Rig Malfunctions And The Torque Is Insufficient?

Today, Shandong Liqiang Company is sharing an article about the causes, inspection methods, and solutions for insufficient torque in rotary drilling rigs, which is truly beneficial for everyone. Liqiang Machinery Company learned from feedback from our after-sales service personnel that some customers encountered insufficient torque in their rotary drilling rigs. We specifically invited our technicians to explain the solutions to this problem, which we will introduce below.#kelly bar piling rig#

First, we need to understand the causes of insufficient torque in the rotary drilling rig's power head. According to our technicians' analysis, the main causes include insufficient engine power, hydraulic circuit problems, sequence valve problems, stacked spring problems, overflow valve problems on the replenishing valve, and insufficient pressure in the main oil pipe without passing through the replenishing valve and overflow valve. We will analyze and solve each of these issues one by one. When engine power is insufficient, symptoms include abnormal engine noise, black smoke, and a drop in engine speed. For hydraulic circuit problems, carefully check the sequence valve circuit and the main oil pipe circuit. If it's a sequence valve problem, adjust the sequence valve directly. For stacked spring problems, check the stacked spring in the reducer. If it's a problem with the overflow valve on the replenishing valve, readjust the overflow valve pressure and release the pressure. If the main oil pipe pressure is insufficient without passing through the replenishing valve and overflow valve, the pressure value needs to be readjusted.

The points analyzed above are the reasons for insufficient torque of the rotary drilling rig's power head. If the power head torque of our small rotary drilling rig is insufficient, it must be addressed promptly, otherwise it will seriously hinder our construction progress. Based on the above, you can troubleshoot and resolve the issue yourself. For parts requiring replacement, please contact Shandong Liqiang Small Rotary Drilling Rig Manufacturer.#kelly bar piling rig#
