July 2020 TYSIM Machinery KR220C new fully electronically controlled Carter rotary drilling rig to Qingyuan County, Lishui, Zhejiang Province to participate in the construction of smart automotive industrial park.It is reported that the geological conditions of the project site are complex, with backfill soil, cohesive soil, silt, strongly weathered and moderately weathered rock formations. At the same time, the formation also has boulite. The pile diameter is mainly 800mm and the depth is about 30 meters. The formation is complex and the construction is difficult. The customer is very satisfied with the use of KR220C rotary drilling rig to overcome various difficulties and meet the designed pile foundation requirements. The rig is stable and reliable, mainly fuel-efficient, and the overall construction progress.
The Carter chassis of TYSIM KR220C rotary drilling rig adopts a pure electronic control system, the cab adopts internal pressurization technology to refuse dust entry, and the air suspension seat increases the comfort of the driver.

l The engine is started with one key, and the scientific Acert series electronic injection diesel engine is adopted, and the combustion emission reduction technology (ACERT) is adopted to meet the European III environmental emission standards;
l The hydraulic main pump adopts an independent electronically controlled main pump to realize scientific engine/hydraulic power management and improve operating performance and fuel efficiency; the tandem dual main pump design eliminates the gear loss of the previous parallel design;
The integrated electro-hydraulic control valve of the hydraulic main valve cancels the pilot oil circuit control, significantly reduces the leakage opportunity and parasitic load on the main pump, and reduces the loss along the oil pipe joint and the oil pipe under the cab;
L electronic intelligent fan fuel saving 3%, each fan independent control, according to their own oil temperature work, increase the reverse function, clean the radiator plate;
l Save 15% on maintenance. The maintenance period is prolonged, the amount of hydraulic oil is reduced, the pilot hydraulic oil filter is omitted, the shell drain filter is replaced by a magnetic filter screen, and the new air filter has a strong ability to accommodate dust. Good parts versatility
L power head part adopts standard mode and strong into rock mode. Increase the construction efficiency of the drilling rig.
