Track-type injection pump, composed of high-pressure pump, explosion-proof motor, stainless steel automatic unload fluid control valve, base, etc. The high-pressure pump is a super high-pressure pump produced with US technology, featuring compact size, low noise, small pulsation, and stable operation. The power end employs forced lubrication, with the high-speed shaft and crankshaft driven by spur gears for smooth and reliable transmission, and low temperature rise, suitable for long-term continuous operation. The hydraulic end components are made of precipitation hardening martensitic stainless steel: hard alloy pillar: highly sealed material, with automatic compensation for sealing, durable and long-lasting. The product is mainly used for hydraulic cutting of water channels and hydraulic cutting of roofs in coal mines, hydraulic fracturing, and has been widely applied underground in coal mines.
