Hydraulic motors are indispensable components of hydraulic systems and they can be widely applied in most equipment that requires rotational motion, which can provide different ranges of torque and speed to satisfy your various requirements.
From this article, we will help you learn In-depth about hydraulic motors applications and functions. And then you can definitely understand how hydraulic motors serve for your manufacturing process.
4 Key Functions of Hydraulic Motors
1. Increasing Working Efficiency
On the one hand, hydraulic motors can generate high torque without gearboxes. On the other hand, they can also provide huge power with relatively small and light weight.
Compared with electric motors, hydraulic motors can convert nearly 90% mechanical energy and have stronger loading capacity, which are suitable for some heavy engineering and machinery. And it will not cause downtime under frequent load fluctuations because it can transmit power stably.
2. Torque Output
Torque output is one of the important functions of hydraulic motors. Hydraulic motors convert the fluid energy of the hydraulic fluid into mechanical energy, thereby outputting driving torque. Most importantly, the level of torque output directly determines its ability to drive equipment.
In addition, you need to note that the torque level mainly depends on two key factors. For one thing, the greater working pressure difference between motors’ inlet and outlet, the greater the torque. For another, if motors have a large displacement, they can help produce higher torque.
3. Consistent Power Transmission
Consistent power transmission benefits from special flow channels design inside hydraulic motors. Regardless of speed and torque changes, hydraulic motors also enable stable and consistent power transmission during operation by adjusting the displacement of hydraulic motors and maintaining constant power.
This great function enables the hydraulic motor to provide strong, stable and long-term uninterrupted power output under various loads and speeds.
4. Precise Movement Control
Hydraulic motors can generate precisely controllable speed through regulating the flow and pressure of hydraulic systems. And they can also adjust the motor’s own displacement to precisely control the rotational position, which can achieve precise movement control.
This function makes hydraulic motors have excellent high torque properties at low speed and they can easily control the rotational position even under heavy loads.
For driving injection molding machines, vehicle drives or other precise movement equipment,
they particularly require hydraulic motors to provide precise speed and direction control and ensure strong power at low speed.
Various Applications of Hydraulic Motors
Hydraulic motors are mechanical devices that provide rotational power in a hydraulic system. Hydraulic motors generally include two types: high speed low torque such as hydraulic vane motor and low speed high torque like hydraulic piston motor. Whether it is high load, high speed movement or precise and stable movement, hydraulic motors all can achieve.
There are some common applications of hydraulic motors below.
Heavy-Loading Mechanical Equipment
Loaders
Hydraulic motors can be commonly seen on loaders’ driving wheels or tracks, which can offer high torque and force to meet high loading demands. For wheel drives in loaders, hydraulic motors need to work with chains and sprocket to drive wheels. For track loaders,
hydraulic motors were connected with planetary gearboxes to move the tracks.
If your loaders need variable displacement or speed control, hydraulic vane motors or hydraulic piston motors are more suitable for your requirements and can better increase working efficiency. If you just want a fixed displacement hydraulic motor, hydraulic gear motors might be worth considering and can generate medium to high torque, which can support most loaders.
Excavators
Hydraulic motors are core components of excavators. They not only drive excavators’ tracks or wheels, but also help drive the slewing mechanism and move key components such as boom and bucket. Specifically, it controls smooth speed and direction of excavators’ swing motion and achieve 360° rotation of boom and arm. This excellent performance allows precise control of excavation even with heavy loads or uneven terrain.
Forklifts
Forklifts are not strict on the specific type of hydraulic motors, hydraulic piston, vane and gear motors all can be applied. Hydraulic motors in forklifts are used to offer rotational force for lifting, tilting and steering during operation. Hydraulic motors help steering units move linkage and achieve easy steering by driving pressurized hydraulic fluid.
And forklifts have high requirements for load capacity and precise movement. Luckily, hydraulic motors can generate tremendous force for moving heavy objects. In addition, hydraulic motors can ensure precise and controlled movements with the help of adjustable displacement.
Agriculture Machinery
Seeders and Harvesters
For seeders, hydraulic motors can provide high torque mechanical rotation energy to support spinning fans of air seeders. And they can control the lift and adjust the depth of seeders according to your specific requirements. These accurate controls can ensure seeds are planted at the correct depth.
For harvesters, hydraulic motors are able to drive its rotating components like header, reel, and auger to efficiently harvest and move crops. And special harvesters such as self-propelled harvesters need precise and controlled movement in the field so low speed and high torque hydraulic motors like hydraulic piston motors are more suitable.
Irrigation Systems
Hydraulic motors play an important role in irrigation systems and they can be applied in drive wheels of water-moving devices or irrigation pumps. For example, hydraulic motors can help control your self-propelled irrigation systems across the field along a set path and drive your irrigation pumps to precisely adjust fluid flow and pressure, which greatly keep the stability of water volume and achieve uniform irrigation during operation.
Material Handling
Automated Convey Equipment
The hydraulic motor can output high torque power and provide consistent speed, making it suitable for automated convey equipment. Through driving conveyor belts and chains, heavy objects can be transported smoothly on the conveyor belt. If you apply hydraulic motors to automated convey equipment, they also provide overload protection during operation. This means the hydraulic motor will stop when overloaded instead of damaging your hydraulic equipment.
Electric Pallet Trucks
Hydraulic motors in electric pallet trucks offer power for hydraulic pumps and generate torque to finish the lifting of forks. When hydraulic motors are started, they can ensure continuous and strong lifting power under heavy loads.
Unlike other complex lifting equipment, electric pallet trucks can just be replaced with a new hydraulic motor if a failure occurs. This design easily recovers operating efficiency of the entire equipment without overall maintenance and minimizes downtime.
Specialized Industrial Machines
Drilling Machines
In order to penetrate the hard foundation, hydraulic motors provide rotational power for drilling machines. And hydraulic piston motors are more suitable for heavy loading drilling machines due to its high power density. If you need higher efficiency for your project, you may also consider using both hydraulic piston and vane motors.
For some tunnel construction and hard foundation drilling, hydraulic motors provide high torque and consistent power transmission, these functions are crucial for penetrating tough materials.
Conclusion
Hydraulic motors can efficiently convert mechanical energy of hydraulic equipment and provide various equipment with high torque and continuous power for operation. After reading this article, I believe you must have a deep understanding about hydraulic motors applications and functions. If you are looking for high quality hydraulic motors to serve for your project, Target can be your reliable partner.
FAQ
Are all hydraulic motors suitable for high torque applications?
No, not all types of hydraulic motors are suitable for high torque applications. Low speed high torque like hydraulic piston and vane motors can be applied for high torque applications such as drilling machines, convey equipment or loaders. And hydraulic gear motors are suitable for high speed and low torque applications such as irrigation systems or blenders.
If you use the wrong type of hydraulic motor, it will greatly reduce the operating efficiency of your equipment or even cause failure.
