Description

Tower-Type Electric Water Source Drilling Rig

The tower-type electric water source drilling rig is a water well drilling device that combines modern design with high performance. This rig uses electric drive and a modular structure, which greatly enhances construction convenience and operational efficiency, making it particularly suitable for water source projects requiring high standards of transportation and installation.

Main Features of the Tower-Type Electric Water Source Drilling Rig

  • Modular Structure Design: The winch and rotary table adopt independent modular designs, resulting in a compact size and structure. This makes disassembly and transportation easy, enabling adaptation to various construction environments.
  • Diverse Configurations: Different models of petroleum rotary tables can be optionally equipped as needed, together with inertia brakes and roller bushings to meet a variety of drilling requirements.
  • High-Performance Winch: Features an extra-wide open drum and Lebus grooving, which significantly extends the service life of the wire rope. It is also equipped with multiple braking and safety devices, emergency lifting systems, and automatic drilling feed functions, enhancing both operational safety and automation.
  • Intelligent Electrical Control System: Internationally renowned electrical components are selected for high system reliability. The control system supports three mutually backup control modes, and multiple safety protection functions can be flexibly set according to actual working conditions.
  • High Efficiency and Energy Saving: Offers high transmission efficiency and low energy consumption, saving much more energy compared to traditional rigs.
  • Low Maintenance Cost: Simple structure, low failure rate, fewer wearing parts, and minimal daily maintenance workload.
  • Stepless Speed Regulation: Uses soft start and stepless speed regulation technology, ensuring minimal impact during equipment start-up and speed adjustment, thus improving operational experience.
  • Digital Centralized Control: Enables digital centralized control, further enhancing operational safety and reliability.

Applications

The tower-type electric water source drilling rig is widely used for domestic water wells, agricultural irrigation, geothermal development, and industrial water extraction projects. Its flexible structure and efficient electrical control system make it capable of handling drilling tasks in urban, rural, mountainous, and various complex working conditions.
