Product Description

KBY120/7-7.5 Hydraulic Dual Fluid Grouting Pump
FunctionThe KBY120/7-7.5 hydraulic grouting pump (hereinafter referred to as grouting pump) is a precision-engineered device designed to harness pressure, accurately injecting easily solidifiable substances or mixtures into rock and soil fissures and voids. This process significantly reduces water seepage and fortifies rock layers and soil structures. Perfectly suited for gas-rich coal mines, well construction, and subterranean waterproofing initiatives, it also excels in tunnel excavation and maintenance, dam foundation treatment, large bridges, skyscrapers, and a wide array of underground projects.
This grouting pump is a fully hydraulic, dual-use marvel-suitable for single or dual fluid applications. Equipped with adjustable pressure settings, it boasts a compact, lightweight, and flexible design, coupled with unparalleled reliability and versatility. Its working media include water, cement slurry, water glass, and more.

1. Structural features
The grouting pump's intricate structure comprises a three-phase asynchronous motor, coupling, plunger pump, oil tank, overflow valve, electromagnetic directional valve, oil cylinder, grouting cylinder, valve chamber, mechanical directional mechanism, high-pressure rubber hose, return oil pipe, water cooler, suction pipe, suction nozzle, discharge pipe, mixer, and beyond.
2. Working principle
With an electric motor propelling the plunger pump via a coupling, hydraulic oil is drawn from the tank into the pump and then expelled at high pressure. This pressurized oil is channeled to the oil cylinder through an overflow valve, directional valve, and high-pressure oil pipe, instigating piston reciprocation. The return oil is cooled in the water cooler and looped back to the oil tank. Connected to the injection cylinder by a piston rod, the pistons of both cylinders move synchronously, ensuring seamless slurry suction and discharge through the respective pipelines and valve chambers, culminating in precise injection into the designated hole.
3. Main structural features
(1) The pistons, piston rings, piston rods, and sealing rings within the oil and slurry cylinders are individually manufactured, facilitating effortless cleaning or replacement.
(2) The mechanism utilizes a metal proximity sensing type, transmitting signals to the electromagnetic directional valve as the sensing point on the piston rod enters the sensing range, ensuring accurate directional control.
Its hallmarks include flexibility, speed, precision, and supreme reliability in commutation.

Safety Warning:
1. Rubber hoses must adhere to the MT98 standard.
2. Prior to pump activation, turn the relief valve pressure handle counterclockwise to its limit (ensuring a zero-pressure start). Install a limiting pin on the pressure regulating handle-do not remove or alter it arbitrarily. Ensure the overflow valve adjustment never surpasses the pump's nominal pressure to prevent overpressure risks. The pump must operate leak-free under rated conditions, and any abnormal noise or vibration mandates machine shutdown and troubleshooting.
3. Refrain from arbitrary replacement of control components.
4. Vigilance is key, as both hydraulic and slurry systems can produce high pressure. All disassembly or installation of hydraulic components and slurry pipelines must occur post pump shutdown and pipeline depressurization. Never attempt repairs or maintenance while the equipment is under load.
5. Operating on hydraulic power, this grouting pump's working pressure should remain within the set limits during use.
6. Never initiate the system under load or pressure conditions. Always ensure the system is completely unloaded prior to starting, to guarantee optimal performance and safety.
7. The motor's direction must be verified and confirmed before commencing operation. Only then can it be officially activated, ushering in seamless and efficient production activities.
8. Continuous supervision is essential during the operation of the grouting pump to ensure safety and efficiency.
9. Once grouting tasks are fully completed, it's imperative to promptly cleanse the grouting pump. Drain any residual liquid immediately to prevent any pipeline blockages, ensuring the longevity and reliability of the equipment.
