1. Product Introduction
(1) Product Overview
Hydraulic Motor is an efficient power device that converts hydraulic energy into mechanical energy, characterized by high torque, stable speed, and high efficiency. Adopting advanced design technology and high-quality wear-resistant materials, it ensures stable and reliable rotational power under various harsh working conditions, and is widely used in engineering machinery, ship propulsion, mining equipment, agricultural machinery and other fields.
(2) Core advantages
High torque output - adopting optimized gear/plunger design, the starting torque reaches over 90% of the rated torque
Wide speed ratio range - the speed can be as low as 5rpm, and the high-speed version can reach 3000rpm, suitable for various working conditions
Efficient and energy-saving - volumetric efficiency ≥ 95%, mechanical efficiency ≥ 90%, reducing system energy consumption
Ultra long lifespan - Key friction pairs are made of special alloys and wear-resistant coatings, increasing their service life by 60%
Intelligent control (optional) - integrated speed sensor, supporting closed-loop control
(3) Typical applications
-Construction machinery: excavator slewing mechanism,
Concrete Pump truck
-Shipbuilding industry: servos, winches, propulsion systems
-Mining equipment: TBM, crusher drive
-Agricultural machinery: combine harvesters, irrigation systems
-Special vehicles: fire truck ladder, airport tractor
