Tapered button bits are an important part of our rotary drilling rig, so the rotary drilling rig has more problems during operation. Once the tapered button bits have problems, the rotary drilling rig cannot work, which will bring losses to the project. Next, let's listen to Kaiqiu Drilling Tools Manufacturer.

　　If it is a rotary drilling rig with the function of throwing soil, the sequence valve that controls the throwing of soil is stuck or damaged, resulting in poor oil return from the oil circuit that opens the friction plate, and the friction plate is in a semi-joined state, which will also cause the power head to roll abnormally In this case, it is enough to clean the sequence valve or replace the sequence valve, or remove the sequence valve and cancel the function of high-speed soil rejection to maintain normal construction. Blockage of oil pipes can also cause similar problems, and the solution is to tidy up the oil pipes.

　　The slewing bearing of the follower frame is damaged, replace the slewing bearing. The main valve relief pressure is too low. There is generally the main safety valve and relief valves for each valve section on the main valve. The pressure relief of the main safety valve and the pressure relief of the relief valve that controls each valve section of the power head will cause the tapered button bits to roll and become weak. If the main safety valve overflows, not only the tapered button bits will be weak in rotation, but also the walking, main hoist, auxiliary hoist, and rotation will all be weak.

　　This problem can be solved by readjusting the main safety valve or the relief pressure of the tapered button bits valve plate relief valve. The general problem is here. I hope that if we encounter this situation again in the future, we can solve it by ourselves or maintain the tapered button bits of our rotary excavator regularly.

　　Learn what causes drill pipe deposits for rotary drilling tools.

　　1. There is residue between the bucket teeth of the rotary drilling rig and the bottom cover of the drill bucket.

　　2. The bottom cover is not closed tightly.

　　3. When drilling into the silt and flow plastic formations, the drilling slag drilled into the drilling bucket is seriously lost during the lifting process, and sometimes it is all lost in the drilling hole.

　　4. The soil cut by the outer edge of the drill bucket of the rotary drilling rig remains on the edge of the bottom of the hole because the bottom of the hole is flat and cannot enter the entrance of the cylinder.

　　5. The teeth of the drill bucket are arranged sparsely, and there will be leakage between the teeth.

　　6. The footage of the drilling bucket is too large, the loading is too full, and the muck is squeezed out from the drainage hole of the top cover.
