Preparation Work Before Hydraulic Dth Drill Rig Construction.

  The construction of hydraulic down-the-hole drilling rigs has the characteristics of fast hole formation, high quality, no noise, and no pollution. Because of its unparalleled advantages in the construction of cast-in-place piles, it is favored by more and more construction units. Therefore, the current price segment Drilling rigs are the main force in underground engineering construction. 1. Construction site:  hydraulic DTH Drilling Rig  for pile foundation construction. In the preliminary preparation stage, the construction site is required to be high. Due to the heavyweight of the rotary drilling rig, the operation of the rotary drilling rig requires the machinery to remain stable, so the operation The site reaches a certain bearing capacity. If the working surface is a relatively soft stratum, the supporting layer should be backfilled so that the site can carry the  hydraulic DTH Drill Rig , and the cranes (above 25t), concrete filling trucks and other eq...

Maintenance of Power Head of Crawler DTH Drill Rig

  The powerhead is the most important working mechanism of the  crawler DTH Drill Rig . Effective maintenance and maintenance measures can better guarantee the performance of the drill and create greater economic benefits for customers. 1. Maintenance and maintenance of powerhead drive device Change the oil for the first time after 100 hours of work in the early stage; change the lubricating oil every 1000 hours of work or 12 months (according to the earliest); check the tightness of all screws and bolts at least once a month. 1. Check and add lubricating oil for the driving device: a. Observe the oil level through the oil level sight hole above the powerhead reducer to ensure that the oil level is between the upper red marking line and the lower red marking line. b. If the oil level is lower than the lower red marking line, you need to add lubricating oil through the oil filler port until the oil level is between the upper red marking line and the lower red marking line. 2. I...

What Is A Water Well Drilling Rigs?

图片
What is a  Water Well Drilling Rigs ? Simply speaking, a water well drilling rig is a mechanical device that drills a water well and completes downhole pipe, well washing, etc., including power equipment and drill bits, drill pipes, core pipes, drill stands, and the like. Below  DTH Drilling Rig Supplier  will introduce the classification and working principle of the water well drilling rig and the correct use of the water drilling rig.  1. Hydraulic oil pump: It is a double-type, large displacement pump provides power for the power head. The small displacement pump provides power for four leg cylinders, landing mast cylinders, and afterburning/lifting cylinders.  2. Four legs: The small well drilling equipment consists of a hydraulic cylinder and a fixed frame. The level of the body can be adjusted at the work site to support and stabilize the body.  3. Mast: It is a frame structure welded by giant steel pipe, channel steel and angle steel. The inne...
