Backfill equipment

FM-XHB-30S fine concrete pump FM-XHB-30S fine concrete pump large German concrete pump technology and main parts, higher stability. Suitable for warm engineering support lining backfill layer, high-rise building walls, floors and transportation of fine stone concrete mortar, as well as tunnels and other underground mine project. After the installation of the machine spray attachment, can be done spraying pumps for concrete, mortar, refractory and green soil injection and throw. Project Unit XHB-25S XHB-30S main variable piston pump variable displacement piston pump type vertical conveying distance M 150m 150m level of transmission distance M 400m 400m theoretical throughput (high / low) M3 / h 25m3 / h 30m3 / h theoretical delivery pressure (high / low) (Mpa) 8Mpa 8.5Mpa maximum bone particle diameter Mm 30mm 30mm valve dispensing valve form S S valve motor power Kw 30kw 37kw concrete delivery cylinder diameter × stroke mm × mm 125 × 1000 140 × 1100 delivery tube inner diameter mm 76mm, 89mm 89mm, 100mm Dimensions L × W × H 3.67 × 1.40 × 1.45 3.85 × 1.62 × 1.63 Features: - The use of advanced valve commutation, to meet transport of fine stone concrete; - Power system adopts domestic famous brand motor, more powerful; - the main oil pump variable displacement piston pump, larger displacement, higher pressure, to meet the high-rise buildings and the construction of long-distance transport requirements; - high and low pressure automatically switch; - glasses, plates and use of carbide cutting ring, wear-resistant, long life; - hydraulic oil cooling + water cooled using air cooling systems, better cooling effect; - uses twin piston pumping mechanism, advanced performance, good continuity; - Electrical system control functions complete with anti-pump control functions, thereby eliminating pipe plug failure; - electrical box is equipped with a wired remote control handle, easy to operate.
