CNHTC's natural gas engines are favored by users at home and abroad. Recently, the Group's companies frequently accept foreign orders. In order to guarantee the natural gas engine plateau performance, according to the arrangement of the group company, the technology center quickly organized vehicles and technicians to go to Qinghai to carry out plateau tests and successfully completed.
China National Heavy Duty Engine
With the help of the Jinan Power Department, the Technical Center conducted tests on two HOWO tractors equipped with 10L and 12L natural gas engines. The test site is from Golmud City along the entire section of the Qinghai-Tibet Highway to the Kunlun Mountain Pass, with an altitude of 2800 to 4767 meters.
All testers overcame the difficult work environment and altitude sickness, and carried out calibration work on the turbocharger speed protection, starting performance, smoke performance, vehicle drivability, etc., and were revised in accordance with changes in the environment, improving and improving natural gas The performance of the engine enables the natural gas engine and the vehicle to achieve a good match.
After seven days of plateau tests, the technicians of the Power Design Institute optimized the engine program to improve the plateau performance of CNHTC's natural gas engines and successfully completed the test.
The drilling jumbo rig is the main drilling equipment in the underground hard rock mine.
Manipulator drilling rig with high level of automation and computerization is not very attractive to mine.
The mine hopes to use the trolley with compact structure, flexible movement, high reliability, high efficiency and high accuracy.
Small enough to enter the shaft through a small section;
Maneuverable and flexible enough to walk in winding and inclined passages;
The versatility can be used to drill hole, bolt hole and cut hole in all directions.
In recent years, several major rock drilling equipment manufacturers in the world, in order to meet the requirements of mechanized mining of thin ore bodies, have successively developed a variety of small rock drills with high power, which can be used to complete the rock drilling operations that could only be completed by pneumatic drill, so as to significantly improve the efficiency of rock drilling and reduce ore dilution rate.
