Our lightweight, efficient drilling equipment is ideal for various well drilling applications including irrigation wells, geothermal wells, and mountain/rock formation projects. All products meet ISO9001 international quality standards, ensuring reliability and excellent after-sales service. We serve customers globally, particularly in Southeast Asia, the Middle East and South America.
High temperatures in drilling rigs typically occur in the gearbox, hydraulic oil, or engine cooling system. For hydraulic oil specifically, excessive heat generation combined with insufficient cooling is the primary cause. Common issues include:
- Leaks in oil inlet pipeline or hydraulic tank
- Clogged inlet filter elements
- Restricted hydraulic system pipelines
- Internal hydraulic pump leakage
