Hefei Changyuan hydraulic products have many years of application history in engineering drilling machinery. The products are widely used in pile drivers, petroleum exploration machinery, drilling machinery, horizontal directional drilling machines and other equipments. The main application products include gear pumps, multi-way valves and cylinders. Our company's gear oil pump (motor) used in the field of drilling machinery mainly includes aluminum alloy series CBKP, CBT4, CBTL, CBQT, cast iron gear pump with CBML, CBVH, CBTLZTD and other series products. Full kinds, variety, in line with the host hydraulic system to the power unit of high pressure, high temperature, impact resistance, high efficiency and other aspects of the performance requirements. In terms of multi-way valve products, our DL series, EDL series and ZD series multi-way valve products are widely used in the field of drilling machinery. The DL series products have compact structure, large flow, high working pressure, good performance and reliable operation. They can realize near and remote control of multiple actuators. Each unit can be equipped with check valves and overload replenishing valves. The series and series-parallel oil paths are combined in two ways: spring reset and steel ball positioning. The ZD series multi-way valve is an integral multi-way valve, which is small in size and easy to install and isuitable for a narrow installation position. There are many application cases of hydraulic cylinder products in the field of engineering drilling rigs, especially the multi-year matching of the cylinder product system on the horizontal directional drilling machine (non-excavation equipment), which makes our company has a very systematic understanding and accumulation of the application condition of the whole machine of this kind of product. After many optimizations and upgrades, HCHC hydraulic cylinders have been able to fully ensure the effective performance of such equipments under various working conditions. HCHC always keep stable cooperaition relationship with many major manufacturers in drilling machinery industry, such as Beijing Prospecting Machinery Factory, Baoding HONGYE, XCMG Group, Drilling Group, HUALI Heavy Industry, DEWEI TUXING Sun, JULI Geotechnical, Wuxi ANMAI, Wuxi Prospecting Plant and provide them with high quality products and services for a long time.
