Hot Selling Model Recommendations:

18/18: An all-rounder, with a discharge volume of 18 m³/min and a pressure of 1.8 MPa, it is compatible with 80% of 4-5 inch down-the-hole hammers on the market, offering excellent value for money and is the top choice for water well drilling customers.

20/20: An upgraded configuration, with a discharge volume of 20 m³/min and a pressure of 2.0 MPa, it increases drilling efficiency by approximately 15% compared to the 18/18 model, making it suitable for contractors seeking higher drilling speeds.

31/25: A heavy-duty flagship model, featuring a large discharge volume of 31 m³/min and a high pressure of 2.5 MPa, capable of driving 6-inch and larger down-the-hole hammers, ideal for deep water wells over 300 meters or large-diameter mining drill holes.

*Note: All models support customization for high-altitude (≤4000m) and high/low temperature environments.

 

 

The stationary diesel screw compressor machine is the ideal companions for water well drilling rigs and down-the-hole drill machines. The working principles of these drilling machines impose strict requirements on the pressure and flow rate of compressed air:

1.Insufficient air volume prevents the hammer from starting properly, directly causing the drilling rig to be unable to operate. This results in equipment idleness and project delays, leading to significant downtime costs.

2.Insufficient pressure leads to difficulties in cuttings removal, low drilling efficiency, and even drill pipe sticking. This significantly increases the risk of abnormal wear and breakage of consumables such as drill bits and drill pipes, and may cause downhole incidents resulting in direct losses amounting to tens of thousands of yuan.

Drilling Hole Diameter	Recommended Impact Hammer Specification	Required Air Volume (m³/min)	Required Pressure (MPa)	Recommended Model
152-180 mm	4-5 inch Impact Hammer	16-20	1.7-1.9	18/18
165-200 mm	5 inch Impact Hammer	18-22	1.8-2.1	20/20
203-305 mm	6 inch and above Impact Hammer	25-32	2.3-2.6	31/25

On-site Configuration Suggestions

Air Source Connection: The air compressor's exhaust port should be connected to the drilling rig's air system via high-pressure hoses. It is recommended to install a storage tank (1-2 m³) to stabilize pressure fluctuations.

Post-treatment Configuration: According to the requirements of the impactor, it is recommended to install an air-water separator to prevent rusting inside the impactor due to moisture in the compressed air.

Pipeline Pressure Loss Control: The pipeline length should not exceed 50 meters, and the inner diameter should not be less than the air inlet diameter of the impactor to avoid excessive pressure loss.

Parallel Operation of Multiple Machines: For scenarios with extremely large hole diameters (>350mm) or extremely deep wells (>500 meters), two air compressors of the same model can be operated in parallel to meet the demand for larger air volume.

 

1. True independent operation, no need for power grid

Equipped with an industrial-grade diesel engine, it can be started with one button and does not rely on any external power. It is particularly suitable for areas without electricity in the wild, areas with frequent power outages, and the initial stage of infrastructure construction.

2. Optimized for drilling operations

Strong high-pressure starting capability: Even at low temperatures or after long periods of shutdown, it can quickly establish pressure and enable the impactor to start working immediately.

Gas supply stability: Large-capacity oil-gas separation tank + intelligent speed regulation, with pressure fluctuations controlled within ±0.05 MPa. Unstable pressure will cause fluctuations in drilling efficiency, and in severe cases, it can lead to the impactor not functioning properly, reducing the drilling speed and directly affecting the project progress and returns.

Dust-resistant design: Two-stage heavy-duty air filters are used, suitable for high-dust environments in mines and drilling sites. If the filtration effect is poor, a large amount of dust will enter the main unit, accelerating the wear of the screw rotor and bearings, and may cause the main unit to be scrapped within 2-3 years, with repair costs reaching tens of thousands of yuan.

3. Excellent fuel economy

The main engine is directly coupled with the engine, ensuring high transmission efficiency.

The system automatically adjusts the rotational speed based on the gas consumption, which can save 5% to 10% of fuel compared to similar equipment. Over the long term, it can save tens of thousands to hundreds of thousands of yuan in fuel expenses for your fleet each year, directly boosting the project's profit.

4. Continuous operation, reliable and durable

Enlarged cooling system, suitable for high-temperature environments above 40℃

Multiple safety protections: shutdown at high temperature, shutdown at low oil pressure, overspeed protection, and air filter blockage alarm.Without these protections, the equipment is highly prone to serious malfunctions under harsh conditions, resulting in prolonged downtime. The repair costs and lost productivity would be much higher than the actual value of the equipment.

5. Easy Maintenance

Concentrated design of maintenance points, no tools required for filter element, oil separator and engine oil replacement

Open frame or detachable silent cover, sufficient space for inspection and repair

Standard operating hour meter, maintenance cycle is clear at a glance

 

 

Comparison Dimension	Common Pain Points & Risks Before Implementation	Solution Effects After Implementation	Quantified Improvement Benefits
Air Supply Volume & Pressure	Insufficient air volume prevents the impactor from starting or causes frequent shutdowns; severe pressure fluctuations slow down drilling progress, directly resulting in project delays and rig idle costs.	Models are precisely matched to the air consumption demand of impactors. Pressure fluctuation is controlled within ±0.05 MPa to stably drive impactors for efficient operation.	Drilling efficiency increased by 15%~25% (taking Model 20/20 as an example), effectively eliminating idle operation losses.
Equipment Failure Rate	Heavy dust in mining sites easily clogs filters; massive dust enters the main unit and accelerates wear of screws and bearings, which may scrap the main unit within 2–3 years and incur high maintenance costs.	Heavy-duty two-stage air filtration system, together with multiple safety protections (high-temperature & low-oil-pressure shutdown), delivers strong resistance to harsh working conditions.	Main unit failure rate reduced by over 70%, service life extended to 8–10 years, greatly cutting major overhaul expenses.
Operating Fuel Cost	Conventional equipment fails to adjust automatically according to load, leading to low fuel efficiency. Long-term high fuel costs severely erode project net profits.	Direct coupling between main unit and diesel engine; intelligent speed regulation automatically matches rotating speed based on air demand to maintain optimal efficiency.	Overall fuel consumption reduced by 5%~10%. Based on annual fuel usage, it can save tens of thousands to hundreds of thousands of yuan in fuel expenses each year.
Maintenance Cost	Scattered maintenance points and narrow repair space lead to long maintenance time with special tools required, raising labor hours and downtime losses.	Centralized maintenance layout; key components can be replaced without tools. Open-frame design provides ample inspection space to shorten downtime.	Single maintenance time cut by 50%, annual maintenance cost reduced by around 30%, and equipment availability raised to over 95%.
