Amid the accelerating wave of localization in geological exploration equipment, the reverse circulation FSL400 geological exploration drilling rig developed by Shandong Zhengyuan Heavy Industry has emerged as a highly regarded "pride of domestic products" in the industry, thanks to its independent innovation core and all-round practical performance. This flagship product, which embodies Shandong Zhengyuan's over a decade of experience in drilling equipment R&D, is reshaping the equipment standards in the resource exploration field with its three key advantages: high efficiency, high precision, and high reliability.
As a star model in Shandong Zhengyuan's "Intelligent Creation" series, the FSL400 is equipped with a reverse circulation drilling system with fully independent intellectual property rights. Its core components - the double-acting hydraulic motor and anti-clogging drill bit - are independently developed by the enterprise. Compared with similar imported equipment, it reduces costs by 30% while increasing drilling efficiency by 40%. In a coal mine exploration project in Shanxi, this drilling rig operated continuously for 72 hours without failure, completing 12 deep hole drillings at an average daily footage of 85 meters, which was 5 days ahead of the planned schedule and set the fastest record for similar regional projects.
Notably, this "Shandong Intelligent Manufacturing" equipment demonstrates amazing environmental adaptability. Its modular crawler chassis is equipped with an intelligent terrain sensing system. During exploration in the permafrost layer at an altitude of 4,500 meters on the Qinghai-Tibet Plateau, it can automatically adjust the crawler pressure to prevent getting stuck; in the extreme high-temperature environment of the Taklimakan Desert in Xinjiang, the independently cooled hydraulic oil tank can stably control the oil temperature within 55°C, ensuring the equipment maintains stable output in a temperature range of -30°C to 60°C.
The concept of green exploration has become its distinctive label. Shandong Zhengyuan has tailor-made a National IV emission standard power assembly for the FSL400, which, combined with energy recovery technology, reduces the fuel consumption per drilling depth to 2.3 liters per meter, 25% lower than the industry average, and reduces nitrogen oxide emissions by 40%. In the geological survey of the Poyang Lake Ecological Reserve in Jiangxi, the drilling rig, with its low-noise design (operating sound pressure level ≤75 decibels), has achieved the ecological goal of "exploration without disturbing birds, drilling without pollution".
At present, the Shandong Zhengyuan reverse circulation FSL400 has served exploration projects such as metal mines, oil and gas fields, and groundwater hydrology in 23 provinces and regions across the country, with a cumulative drilling footage exceeding 180,000 meters. "From equipment delivery to after-sales response, Shandong Zhengyuan's full-chain service makes us worry-free," said Wang Lei, captain of a geological team in Gansu, whose comment echoes the voices of many users. This drilling rig, which undertakes the mission of domestic equipment breakthrough, is writing a new chapter of "Made in China" in the field of geological exploration with its hardcore strength.
