Product Description

KBY120/7-7.5 Hydraulic Dual Fluid Grouting Pump
FunctionThe KBY120/7-7.5 hydraulic grouting pump, hereinafter referred to as the 'grouting pump', is an advanced device engineered to inject mixtures that solidify easily, utilizing precise pressure to fill cracks and cavities within rock layers or soils. This grouting process effectively minimizes water seepage and strengthens foundational rock and soil structures. Specially designed for gas-containing coal mines, well construction, and subterranean waterproofing projects, this versatile pump is also well-suited for tasks such as tunnel excavation and maintenance, as well as the foundational treatment of dams, expansive bridges, towering buildings, and diverse underground ventures.
This cutting-edge grouting pump is a fully hydraulic dual-purpose marvel capable of handling single or dual fluid operations with adjustable pressure settings. It stands out with its compact design, lightweight make, remarkable flexibility, and dependable performance, making it applicable across a wide array of uses. The pump's working mediums include water, cement slurry, water glass, among others.

1. Structural features
The structural composition of the grouting pump boasts a sophisticated blend of components: a three-phase asynchronous motor, resilient coupling, efficient plunger pump, oil tank, precision overflow valve, electromagnetic directional valve, sturdy oil cylinder and grouting cylinder, valve chamber, mechanical directional mechanism, robust high-pressure rubber hose, return oil pipe, water cooler, suction pipe, suction nozzle, discharge pipe, and a dependable mixer, among others.
2. Working principle
At the heart of its operation, the electric motor drives the plunger pump via a coupling, sucking hydraulic oil from the oil tank and discharging it at high pressure. This high-pressure oil flows into the oil cylinder through an overflow valve and directional valve, propelling the piston in a reciprocating motion. As the return oil flows through the water cooler, it completes a cycle back to the oil tank. The synchronized movement of the pistons in both the oil and injection cylinders ensures the slurry is meticulously sucked in and discharged through the dedicated pipelines and valve chambers, ultimately being injected into the designated injection hole.
3. Main structural features
(1) The pistons, piston rings, piston rods, and sealing rings within both the oil and slurry cylinders are meticulously manufactured separately to facilitate effortless cleaning or replacement.
(2) The mechanism operates on a metal proximity sensing principle. This innovative design transmits signals to the electromagnetic directional valve, triggered by the movement of the sensing point on the piston rod when it reaches the sensing range, thereby achieving precise directional control.
This system is characterized by its flexible, swift, accurate, and reliable commutation capabilities.

Safety Warning:
1. Ensure all rubber hoses comply with the MT98 standard for optimal safety and performance.
2. Prior to starting the pump, rotate the relief valve pressure regulating handle counterclockwise to the maximum limit position to ensure a zero-pressure start. A limit pin must be installed on the pressure regulating handle, and it is imperative not to remove or alter it. The overflow valve should be adjusted within the nominal pressure of the pump to prevent overpressure operation, as the pump's integrity under rated conditions is paramount. Monitor for noise and vibration, halting operations if abnormalities are detected for immediate troubleshooting.
3. Do not arbitrarily replace control components to maintain system integrity and functionality.
4. Be aware that both the hydraulic and slurry systems of this grouting pump can generate significant pressure. To prevent accidents, all disassembly or installation of hydraulic components and slurry pipelines should only be conducted when the pump is stopped and all pipeline components are depressurized. Never attempt repairs or maintenance while the equipment is under load.
5. This grouting pump operates on hydraulic pressure, and it is crucial that the working pressure does not exceed the set limits during operation to ensure safety and longevity of the equipment.
6. To ensure seamless operation and avoid potential mishaps, always start the system without any load or pressure. Make sure the system is fully unloaded before initiating the start.
7. Confirm the motor's direction is correct before proceeding with an official start. This ensures that the system can smoothly transition into normal production operation.
8. For optimal safety and efficiency, the grouting pump must be attended by personnel during its operation. This practice ensures the system runs smoothly and any issues can be addressed promptly.
9. Upon completing the grouting process, it is imperative to clean the grouting pump immediately. Drain any remaining liquid meticulously to prevent pipeline blockages and maintain optimal system performance.
