What should you pay attention to when drilling rock with a rock drill?
In order to improve rock drilling efficiency, reduce or timely discover faults during rock drilling, the following operational principles should be followed: First, the eye position must be accurate, the direction of the eye should be cold, and the angle of the air leg should be accurate; Second, the drill rod and the rock drill to be held in a straight line; Third, the rock drill , gas leg (or propulsion device) should work smoothly; Fourth, change the rock drilling position, change the air leg erection angle and replace the drill rod; 5. Concentration of ideas, concentration of energy, and concentration of time; Sixth, look at the blasthole eye is round, diligently see whether the drill rod is turned in the center of the blasthole, diligently see if the discharged rock powder is normal, and see if the rock drill is working normally; 7. Listen carefully to the operation sound of the rock drill, determine whether the shaft thrust, wind pressure and lubrication are normal, listen to the sound of the hole, and determine whether it encounters faults and joints. 8. Regularly adjust the amount of water, air volume and air leg angle.
Honed tube is well known as hydraulic cylinder tube in industries. As honed tubes are the most important material of manufacturing hydraulic cylinders Honed Tube,Hydraulic Honed Tube,Hydraulic Cylinder Tube,Honed Steel Tubing Shandong Guanzhou Iron and Steel Group Co., Ltd. , https://www.guanzhouiron.com
We manufacture the honed pipes using our factory`s [Suitable To Hone" Steel Cold Drawn Seamless Tubes (CDS tubes)& Steel Cold Drawn Welded Tubes (CDW tubes). In order to produce extremely precise ID dimensions and smoothly ID surface, the honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material. Besides the honing process, we also use the SRB process (skiving and roller burnishing) to produce honed tubing. Honed tube is ready to use for hydraulic cylinder applications without further ID processing.
Honed precision tubes are made of seamless steel tubes, with raw materials hot rolled, under cold drawn process then honing. They are widely used for manufacturing hydraulic cylinders. Honing is a finishing method whose goal is to ensure perfect surface grade, in our case final treatment of the inner diameter of the tube. Advantage of this classic procedure honing is high geometrical accuracy of the shape with minimal conicity and waviness of the surface.
Main applications of Hydraulic honed tubing:
Honed tubing and SRB tubes (skived and roller burnished tubes) are mostly used as cylinder tube, such as hydraulic cylinder tube and pneumatic cylinder tubing, which are widely used for manufacturing and repairing hydraulic cylinders and pneumatic cylinders. As honed tube usually has very accuracy dimension tolerance and good surface smoothness, so this product is also used in applications where precision dimension or high smooth surface is need.
