With over thirty years of deep expertise in the hydraulic field, Guorui Hydraulics, a professional provider of hydraulic components and system solutions, steadfastly adheres to its enduring business philosophy: "Win markets with quality, enter markets with integrity, win markets with service, and secure markets with brand." Driven by an uncompromising pursuit of quality, the company was not only among the first to obtain the Quality Management System certification from the China Quality Certification Centre (CQC), but has also established a rigorous four-stage internal quality control system spanning the entire product lifecycle – from raw material screening, manufacturing process monitoring, finished product inspection before shipment, to continuous improvement of mature products. This stringent quality assurance has earned Guorui products multiple internationally recognized certifications, including the EU CE Mark and classification society certifications.

Recently, Guorui Hydraulics has channeled its profound technical expertise and innovative spirit into a flagship product: an intelligent fan motor with an integrated automatic speed control controller. This product combines a high-performance fan motor, a proportional relief valve, and the core GHC12 controller into a single, highly integrated unit, achieving intelligent closed-loop control for cooling systems.

Its core advantage lies in the advanced automatic speed regulation function. The system continuously detects the fan's actual speed and feeds this signal back to the built-in GHC12 controller. Based on the difference between the set value and the feedback value, the controller precisely outputs a PWM (Pulse Width Modulation) signal to dynamically adjust the flow supplied to the motor, enabling smooth and efficient variable speed control of the fan. This not only significantly enhances cooling efficiency but also effectively reduces energy consumption, lowers noise levels, and extends equipment lifespan.

This innovative product is specifically designed for demanding operating conditions and is particularly suitable for construction machinery such as concrete pump trucks and pavers, where high cooling system performance and compact spatial layouts are critical requirements. Its outstanding intelligent and integrated design provides OEMs with a more reliable, energy-efficient, and easily integrated cooling solution.

Regarding technical specifications, this intelligent fan motor features a displacement of 16 mL/rev, a rated working pressure of 15 MPa, a safety valve setting pressure of 20 MPa, and a rated speed of 2000 rpm. It offers stepless speed regulation across a wide range of 500 to 3000 rpm (rotation direction: CCW - Counter Clockwise). Tested with hydraulic oil, the controller incorporates the crucial speed feedback function and operates across a wide voltage range of 9 to 32 V DC, ensuring strong adaptability and stable operation in diverse power supply environments.

The launch of this integrated smart controller fan motor by Guorui Hydraulics not only demonstrates the company's foresight in the intelligent and integrated development of hydraulic technology but also reaffirms its steadfast commitment to serving the market with innovative quality and winning trust through a reliable brand.
