OMP BMP BM1 Hydraulic Motor for Rotary Broom

A rotational hydraulic motor is a device that converts hydraulic pressure into rotational motion. This type of motor is typically used in heavy machinery or industrial equipment where torque and power are required. The hydraulic motor is often used in applications where a traditional electric motor would be impractical, either due to size, weight, or power requirements.

Product Introduction

OMP BMP BM1 Hydraulic Motor for Rotary Broom Applications

Overview
Rotary hydraulic motors are robust devices engineered to transform hydraulic pressure into precise rotational motion. These motors are particularly valuable in heavy machinery and industrial equipment where substantial torque and reliable power are essential. They serve as optimal solutions in scenarios where electric motors face limitations in size, weight, or performance.

Versatility and Design
Hydraulic motors are available in various configurations to meet diverse operational demands. Certain models deliver high torque at low speeds, making them suitable for heavy-duty sectors such as mining, construction, and maritime applications. Others prioritize high-speed, low-torque performance for uses like conveyor systems and pumping units.

Operating Principle
These motors function by utilizing pressurized hydraulic oil to actuate internal components-such as pistons, gears, or vanes-which in turn produce rotational movement. This motion is transmitted to external mechanical parts including shafts and gears, enabling controlled and powerful operation.

Key Advantages

1. High Efficiency: By leveraging existing hydraulic system pressure, these motors minimize energy consumption and operational costs.

2. Durability: Designed to perform reliably in challenging environments, including exposure to high temperatures, moisture, and corrosive agents.

3. Precise Control: Operators can effortlessly regulate speed, torque, and rotational direction using intuitive control systems.

Hydraulic motors represent a dependable and efficient method for converting fluid power into mechanical rotation. Their combination of durability, operational flexibility, and ease of integration makes them indispensable across numerous industrial applications. As technology advances, these motors will continue to play a critical role in powering essential machinery worldwide.

Max. allowable back pressure		10MPa

Allowable Lateral Load (At Rated Speed)

◎ Intermittent operating pressure indicates the maximum pressure allowed at the inlet; continuous operating pressure refers to the differential between inlet and return ports
◎ Avoid simultaneous operation at maximum speed and maximum pressure
◎ Intermittent duty must not exceed 10% of any one-minute interval
◎ Recommended fluid: anti-wear hydraulic oil with viscosity 37–73 cSt and cleanliness ISO 18/13
◎ Maximum oil temperature: 80°C
◎ Advanced dynamic seal design supports back pressure up to 10 MPa; for optimal service life and performance, maintain below 5 MPa
◎ If exceeded, connect an external drain pipe while ensuring the motor remains oil-filled. Throttle the drain to maintain back pressure above 3.5 Bar, aiding contaminant removal and cooling
◎ Execute a run-in period before full-load operation: run for 1 hour at 30% of maximum pressure
