Reverse Circulation Drilling Rig by Features

This drilling rig combines hydraulic drive technology with reverse circulation and slag removal. A hydraulic reverse circulation drill uses a hydraulic system to power the drill bit and drill pipe, enabling high-speed rotation. Its reverse circulation function rapidly removes rock cuttings. Compared to traditional drilling rigs, this combination of technologies significantly improves drilling efficiency.

It uses air lift reverse circulation technology, which actually mixes compressed air with circulating fluid (mud, cuttings) to form a gas-liquid flow, which causes a pressure difference between the inside and outside of the pipe, and eventually discharges the cuttings at the bottom of the hole. It is often used in the construction of large bridges, water resource exploration and geothermal development projects.

It mainly uses the vacuum suction of the gravel pump to achieve reverse circulation. This equipment is suitable for municipal engineering projects, such as drilling urban rainwater wells and sewage wells, and is also suitable for the construction of small and medium-sized bridges.

It features a crawler chassis that allows for flexible movement and a stable support system, making it adaptable to a variety of complex terrains. It is also a drilling machine that integrates full hydraulic drive and reverse circulation slag removal technology.

This equipment achieves drilling through impact crushing and reverse circulation. Its unique feature is its ability to penetrate hard rock formations such as granite and pebble rock, and its reverse circulation technology removes the rock cuttings and mud mixture from the drill pipe.

It is an efficient and versatile drilling equipment. It has an off-road truck chassis, so it has strong mobility and can adapt to various complex terrains such as Gobi, desert and hills.

Its advantage lies in its lightweight design, which allows it to enter smaller areas. It is often used in geological exploration, water well drilling, farmland irrigation and small pile foundation projects.

The equipment can achieve efficient drilling and wall protection through the joint work of two power heads. It is suitable for large-scale building foundation engineering and transportation infrastructure construction.
Framework of Reverse Circulation Drilling Rig
A reverse circulation drilling rig mainly consists of a power system, a reverse circulation slag discharge system, a drilling system, a control and operating system, a structure and walking system, and a security protection system.

The power system provides energy for the normal operation of the entire machine. Its core components are divided into two main parts: the main power source (such as a diesel engine or electric motor) and the auxiliary power source (generator). The power system converts the mechanical energy output by these power sources into hydraulic energy, thereby ensuring the efficient and stable operation of the entire machine.

The function of the circulation system is to discharge cuttings and cool the drill bit. It realizes reverse circulation through a mud pump and is equipped with a mud purification device that can filter and recover rock debris.

Its task is to directly contact the formation and complete the drilling process. This process is mainly realized by the drill tool assembly (drill bit, drill pipe, drill collar), rotary mechanism and lifting mechanism.

The control system can quickly and efficiently control the movement of the drilling rig. It mainly consists of control console, hydraulic control system and electrical control system.

Common types include crawler and tire chassis, which can meet the different needs of complex terrains and flat roads, and enable flexible movement of the drilling rig.

It is a guarantee for the safety of equipment and personnel and can avoid operational risks. Safety protection system includes overload protection, height limit and emergency stop button.
Reverse Circulation Drilling Rig Power Head
The power head is an essential part of a reverse circulation drilling rig. Its main function is to drive drilling tools (drill bits and drill rods) and provide them with rotational power to achieve cutting of rock and soil. It is mounted on the mast and slides up and down the mast. Additionally, the power head serves as a channel for compressed air or mud to enter the interior of the drill pipe. The power head directly affects the efficiency and accuracy of drilling.


Reverse Circulation Drilling Rig Gravel Pump
The gravel pump is the core device of the reverse circulation drilling rig for the slag discharge process. It is also a type of centrifugal pump. Its working principle is to generate strong suction, form a pressure difference, and then quickly discharge the drilling residue at the bottom of the hole out of the hole through the drill pipe. Its slag discharge cleanliness is also extreme, which greatly improves the construction efficiency of the entire equipment.
