Drill machine is a simple, lightweight , economical tunneling machine , the stone block mining machine important , are the percussion device , and the need for both oil and water and gas with the use of a variety of auxiliary media , which on the one hand the reliability of the device , security put forward higher requirements ; hand, but also to the operation and maintenance of equipment to bring some difficulties. Scientific diamond blades use and maintenance of drilling machines, not only to ensure safety in production , to prevent fatal accidents is important, but also to improve equipment performance , working life, production efficiency is important.
Preparations before start
1 , the new purchase to the drilling machine, inside coated with anti-rust grease viscosity , clear and must be removed before use . Reload , all moving parts to be lubricated table Mina . Installed, the drilling machine is turned pressure gas line , open a small wind operation , check its functioning properly.
2 , the automatic oiler inject lubricating oil, used oil is 20 #, 30 # , 40 # oil . Loaded oil containers should be clean , covered , to prevent rock dust and dirt into the oiler .
3 , inspection workplace pressure and water pressure. Wind pressure is 0.4-0.6MPa, air pressure is too high will tile saw blade accelerate the mechanical parts of the damage , too low will reduce drilling efficiency and corrosion mechanical parts. Pressure is generally 0.2-0.3MPa, water pressure is too high, the water will destroy the lubrication poured inside the machine , drilling machine efficiency and reduce corrosion mechanical parts ; too low flush adverse effects .
4, using Qianzai meets quality requirements , the failure of Qianzai prohibited.
5 , duct access drilling machines, should be placed inside the dirt off the gas will blow . Connection pipes money to waterproof joints rinse the dirt, wind and water pipes must be tightened to prevent shedding wounding .
6 , the solder tail into the drilling head , forced clockwise Qianzai If we can not move, that has jammed inside the machine phenomenon , should be promptly treated .
7 , tighten the bolts , open air check the functioning of the propeller , in normal operation can begin work .
8 , rail drilling machine should stand a good prop , and check the functioning of the propeller , air leg rock drill rock drill machine and upward air leg must check the degree of flexibility and so on.
9 , on request of the hydraulic rock drill hydraulic system has a good seal to prevent contamination of hydraulic oil , hydraulic oil to ensure that there is constant pressure.
Precautions when working
1 , opening the eyes should be rotated slowly until the depth of the hole to reach 10-15mm later, and then gradually moved to full operation . In the drilling process, according to the drill rod hole straight forward design , and is located in center of the hole .
2 , should be reasonable in the drilling test drive shaft thrust. Shaft thrust is too small, machine-generated bounce , vibration increases , drilling efficiency ; axis thrust too much , Qianzai top tight eyes, so that the machine is operating in overload , easy to premature wear parts , making drilling slowed .
3 , drilling machines jamming , should reduce the thrust axis , you can gradually become normal. If invalid , should be immediately shut down. First slowly rotating drill rod with a wrench , and then open the gas pressure Qianzai slowly rotating , prohibit the use of the concrete polishing pads approach to beat Rod .
4 , the situation often observed row powder . Pink row is normal, mud along slowly outflow orifice ; contrary, to forcefully blow holes. If you are still valid , you should check Qianzai water holes and solder tail state, and then check the water needle , replace the damaged parts.
5 , to observe the oil reserves and oiling conditions , regulate the fuel injection . Oil operation, easy to premature wear of parts . When the oil is excessive, will cause face pollution.
6 , the operation should pay attention to the sound of the machine , observe its functioning , identify problems and timely treatment.
7, pay attention Qianzai working condition , abnormal timely replacement .
8, the operation up rock drill air leg should pay attention to the gas , to prevent drilling machines made bobbing
