Good operation and maintenance habits c♥σ§an avoid excessive consumption of dril≤₹l rods. Here are some examples in th✘♠∏is regard.



1. Beat butter frequently¥♥"→


During the use of the crushing ham♣γ♥mer, grease shall be applied r₹♦₹↓egularly so that the drillφ> rod can work stably under l→$‍₹ubricated working condition→♠s. Long time without÷₩∑ butter or directly without ©∏butter will accelerate th<©e wear of the drill rod‌™₹, resulting in premature scra∞πδεpping or accidental damage. The authoβ↔r has seen that without butter, the¥$ drill rod can not be take♠&₹♦n out directly in the cylind≤ ≥∏er block.



2. Avoid using the drill rod×★♦ as a bucket


It is common to use the drill rod as a ✔₹ bucket. Taking the drill rod to pic≤​↕÷k up the stone will often ★★αlead to the accidental fr₩★acture of the drill ro≈ $‍d.



3. Avoid long blows


When striking at the same cru‍ελ♥shing point for a long time×₽γ, select the appropriate÷•‍" crushing point for operation when usi↔☆ng the crushing hammer. If the cru ≈shing fails to be str<¶uck at one point, re select anot♠←her crushing point for crushing. Th∏₩e drill rod can not break the roc₹∞​k when it is hit at the ≈¶ ↔same breaking point for a long time•₩. At this time, the i&ε£mpact energy of the bαφreaking hammer cannot diffσ¥λuse, but accumulates at the dril₽∏✔£l rod head, resulting in the™↔÷× increase of its temperature and t✔÷​he formation of mushroom shaped tip ac↔Ω©cumulation, resulting in the decre €ase of the annealing hardnes≥ δ₽s of the drill rod, making the≤‍   drill rod extremely wear-♦‌₹¥resistant, greatly shorte£☆φ₹ning the service life£↔♠ of the drill rod.



4. Replace the inner an¥≥d outer sleeves in time


Due to the wear of the inner sl★★eeve, the clearance b♦σ∏ etween the inner slee↓↔∑ve and the drill rod is too large.♦$♥ This situation is very easy t¶™ >o cause the eccentric and empty play ♥©®φof the hammer, and it is easy to bre₩<÷±ak the block at the tail£© of the drill rod. Theref&♣ore, the inner sleeve and the oute₹σr sleeve should be replaced in time>∑ for the normal use of the d®λαrill rod. Generally, φ the clearance between the ou λter sleeve and the drill rod is 3-5≥​mm. If it exceeds 5mm, it should be con$←₽αsidered to replace the outer sleeve. Fo €r every 2 sets of outer sleeves, it s¶‌♣hould be considered to replace one s≠εet of inner sleeve. Many car owners beγ ♠§lieve that as long as the"λ¶♣ sleeve is not broken, it will not∞φ₩β be replaced, which also causes abnorma☆®↔×l wear and tear of the drill rod.σ↕
