Kaishan KSZJ High Air Pressure Portable Screw Compressor (15–30 Bar)

Core Engineering Features & Performance Advantages

Technical Parameters

• Deep Water Well & Geothermal Rigs: 2.5–3.0 MPa (25–30 bar) models (e.g., KSZJ-31/25, LGZJ-36/30) provide optimal back-pressure flushing for deep holes from 300m to 600m, perfectly matching Kaishan KW300, KW450, and KW600C rigs.
• Open-Pit Mining & Quarry Blast Hole Rigs: 1.5–2.3 MPa (15–23 bar) models (e.g., KSZJ-18/17, KSZJ-29/23) drive 4" to 8" DTH hammers on crawler rigs like Kaishan KG510 and KG9.
• Dual-Condition Flexibility: Switching between 25 bar and 35 bar modes allows contractors to shift easily between deep borehole drilling and high-volume shallow bench blasting with a single investment.

Q: What is the dual working condition switching design on the KSZJ series?

A: Select KSZJ models incorporate dual-mode pneumatic switching, enabling operators to toggle between high-volume/medium-pressure mode (e.g., 34 m³/min @ 17 bar) and ultra-high-pressure mode (e.g., 31 m³/min @ 25 bar) via a single switch to adapt to varying ground conditions.

Q: How does the microcomputer control system protect the compressor?

A: The onboard digital monitor continuously evaluates discharge pressure, exhaust temperature, oil pressure, engine water temperature, and fuel levels. If parameters exceed safe operating limits, the system triggers audio-visual alarms and automatically executes protective shutdown.
