A drilling rig is a complex machine used in various industries for drilling holes in the ground to extract natural resources such as oil, gas, or minerals. To perform its function effectively, a drilling rig requires four basic systems that work together to facilitate the drilling process. These systems are:

The power system of a drilling rig provides the necessary energy to drive the various components and perform drilling operations. It typically consists of diesel engines, electric motors, or a combination of both. The power system generates mechanical power that is transmitted through the rig's drivetrain to rotate the drill bit and other drilling equipment.
In addition to providing power for rotation, the power system also supplies energy for other functions, such as lifting and lowering the drill string, operating hydraulic systems, and powering auxiliary equipment on the rig.

The hoisting system is responsible for lifting and lowering the drill string, which consists of the drill pipe, drill collars, and the drill bit. It is used to transfer the weight of the drill string and the applied force to penetrate the ground. The hoisting system typically consists of a drawworks, derrick or mast, crown block, traveling block, and drilling line.
The drawworks is the primary component of the hoisting system and houses the drum and brake mechanism. It controls the speed and direction of the drilling line, allowing for controlled lifting and lowering of the drill string. The derrick or mast provides the vertical support for the drilling equipment and serves as a framework for raising and lowering the drill string.
The crown block is positioned at the top of the derrick or mast and redirects the drilling line to the hoisting system. The traveling block moves up and down along the drilling line, allowing the drill string to be raised and lowered. Together, these components form a system that enables the movement and control of the drill string.
The rotating system is responsible for rotating the drill string and the drill bit. It applies torque to the drill string, allowing the drill bit to penetrate the ground. The rotating system typically consists of a rotary table or top drive, kelly or top drive swivel, and the drill string itself.
In conventional rotary drilling, a rotary table is used to provide the rotational motion. It is driven by the power system through the rig's drivetrain. The kelly, a square or hexagonal pipe, is connected to the rotary table and transmits the rotational motion to the drill string. The drill string, comprising interconnected sections of drill pipe, transmits the rotational force to the drill bit at the bottom.

Alternatively, some drilling rigs use a top drive system instead of a rotary table. A top drive is a motorized device that is suspended from the drilling rig's derrick or mast. It directly drives the drill string, eliminating the need for a rotary table and kelly.
The circulating system, also known as the mud system, plays a vital role in drilling operations. It circulates drilling fluid, commonly referred to as mud, down the drill string and back to the surface. The drilling fluid serves several purposes, including cooling the drill bit, carrying the drilled cuttings to the surface, providing hydraulic pressure to control formation fluids, and stabilizing the wellbore.
The circulating system comprises various components, including mud pumps, mud tanks, mud pits, shale shakers, and mud cleaning equipment. Mud pumps generate the necessary pressure to circulate the drilling fluid. Mud tanks and pits store and process the drilling fluid, allowing for the removal of drilled cuttings and the adjustment of fluid properties.

The KG910E low pressure crawler drilling rig adopts both electromotor and diesel engine for the hydraulic pump of the hydraulic system. The electromotor and diesel engine should be used separately. When you use it as an electric drilling machine, the machine's working noise is lower, and the other advantages include good eco-friendliness, high safety level, and low using cost. As a set of premium hybrid electric construction euiqpment, however, if there is no extra power supply, it can be shifted to diesel engine driving mode for long distance drive.
Feature
1. Walking mechanism
A ball piston motor and planetary reducer system is adopted for our low pressure crawler drilling rig to achieve higher gradeability, lower walking system pressure (from 15Mpa to 11Mpa), and longer motor service life.
2. Hydraulic system
A large displacement gear oil pump is adopted for higher rotation speed (Max. speed = 120r/min). Besides, fast rotation and lift group valve, and new type flow divider are also used.
3. Gyrator
We choose the low speed and high-torque generator motor to replace the original ball piston motor to achieve longer motor service life. The air inflow pedestal and the gyrator's housing of the low pressure crawler drilling rig are separated to prevent the compressed air from entering the oil tank through gyrator's housing and motor.
4. Motor
Main motor: electromotor (Y180L-4 type, 22kW, rpm)
Backup motor: diesel engine (CFZSGM type, 18.4kW, rpm)
