Diesel small well drilling machine is a kind of efficient drilling equipment, which is widely used in various small well drilling projects. Here is a detailed description of the device:
First, the working principle
The working principle of diesel small well drilling machine is mainly based on pump suction reverse circulation drilling technology. Under the action of atmospheric pressure, the circulating liquid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well hole. At this time, the turntable drives the drill pipe and drives the drill bit to rotate for drilling. The negative pressure created by the mud pump draws the debris mud into the drill pipe cavity, then rises to the faucet and drains through the mud pump into the settling tank. After settling, the circulating fluid continues to flow into the hole, so the cycle is repeated, forming a reverse circulation drilling work.
Second, the main structure and composition
Diesel small drilling machine is mainly composed of diesel engine, friction clutch, drilling head, drilling rod, controller and other parts. Among them, the diesel engine is responsible for providing power, the drilling head is responsible for drilling work, the drilling rod is responsible for transmitting power, and the controller is responsible for monitoring and control of the entire drilling process.
3. Characteristics and advantages
Compact structure: Small diesel drilling machine compact size, light weight, easy to transport and install.
Wide range of application: The equipment is suitable for a variety of geological conditions, including clay, sandy soil, rock, etc.
High drilling efficiency: the diesel engine has large power and can provide stable power output to ensure the efficient drilling work.
High degree of automation: some equipment has realized automatic control such as slag discharge, water supply, parking, reversal, etc., reducing the difficulty of operation.
Less water consumption: Compared with other types of well drilling machines, diesel small well drilling machines use less water during the drilling process and have little impact on the environment.
Low cost: The equipment is affordable, and the maintenance cost is low, suitable for all sizes of drilling projects.
4. Application field
Diesel small well drilling machine has been widely used in agricultural irrigation, industrial water use, groundwater exploitation and other fields. It can not only be used for drilling civil eating Wells, ground source heat pump air conditioning Wells, engineering precipitation Wells, etc., but also for farmland irrigation, factory water intake and other scenarios. In addition, the equipment can also be used in geological exploration, hydrogeological survey and other fields, providing an important basis for subsequent engineering design and construction.
5. Operation and maintenance
When operating a diesel small well rig, it is necessary to follow the correct operation methods to ensure the safe operation of the equipment. At the same time, regular maintenance and maintenance of the equipment is also essential. Through timely maintenance and maintenance, the service life of the equipment can be extended and the performance of the equipment can be improved.
6. Market situation and development trend
With the continuous development of construction, agriculture, industry and other fields, the market demand for diesel small well drilling machines is also increasing. At the same time, with the continuous progress of technology and the intensification of market competition, the performance and quality of the equipment are also constantly improving. In the future, diesel small well drilling machines will develop in the direction of more intelligent, efficient and environmental protection.
To sum up, diesel small drilling machine with its high efficiency, stability, environmental protection characteristics, plays an important role in construction, agriculture, industry and other fields. With the continuous progress of technology and the continuous expansion of the market, the application prospect of the equipment will be broader.
