This section provides an overview for high pressure cylinders as well as their applications and principles. Also, please take a look at the list of 11 high pressure cylinder manufacturers and their company rankings.
A high-pressure cylinder is an actuator that uses a motor to rotate a ball screw to push or pull a high load object in a linear direction.
Conventional hydraulic cylinders require a pump to operate and maintain thrust, but high-pressure cylinders do not. Hence, a high-pressure cylinder does not require a pump to maintain thrust, thus reducing power consumption.
The advantage is that the system configuration is simple because no piping to transport oil is required. Only cable connections are needed to drive the motor.
Even if power is lost in the event of a power failure, the load is maintained by the operation of the motor with brake, thus eliminating the risk of a fall accident.
High-pressure cylinders are mainly used in heavy machinery, construction machinery, and agricultural machinery that require high-load linear motion.
Specifically, high-pressure cylinders are used to lock machine parts, open and close doors, and adjust the angle and position of various parts. They are also used for lifting and lowering heavy objects.
In the medical field, the lifting and lowering function of high-pressure cylinders can be used to move wheelchairs and beds.
The maximum thrust is widely defined according to the target load. High-pressure cylinders are also used in a wide range of operating temperatures, from low to high.
High-pressure cylinders are a device composed of a motor, gear head, and ball screw. They work in tandem to achieve a linear expansion and contraction motion.
The principle of operation is described below. First, rotational motion generated by the motor is transmitted to the gear head, causing the gear head to rotate.
Since the gear head is connected to a ball screw, the screw extends or retracts according to the direction of rotation of the head, thereby adjusting the amount of expansion or contraction.
Note that a ball screw is a component with a nut or bearing ball connected to a threaded rod. The rotational motion from the gear head can be converted into linear motion.
As a result, parameters such as position and speed in linear motion can be easily controlled by motor motion.
The motion is relatively stable even at low speeds and can be smoothly shifted during acceleration.
Therefore, even if you want to stop the cylinder at multiple positions (multi-point stop), it can be used stably.
