Prinsip Kerja

The YWZ8 series electric hydraulic drum brake operates using hydraulic power to generate braking force and a drum-based mechanism to stop motion. Here’s how it works:

1. Hydraulic Drive: Hydraulic oil is pumped through a control valve into the hydraulic cylinder of the brake. For example, in the YWZ8-200/E23, the hydraulic system generates enough force to apply the friction pads to the drum, creating the necessary braking torque of 135-200 Nm.
2. Drum Braking: In this braking system, the friction pads, activated by hydraulic pressure, press against the rotating drum. The YWZ8-300/E30, with a braking torque of 200-320 Nm, ensures smooth and reliable stopping power even under high loads.
3. Clearance Adjustment: The brake’s clearance, such as the 0.7 mm clearance in the YWZ8-200/E23, ensures optimal contact between the friction pads and the drum. Adjusting the clearance is crucial to maintain braking performance and prevent excessive wear.

Petunjuk Penggunaan:

1. Instalasi:
   • For correct installation, ensure that the brake, such as the YWZ8-200/E23, matches the required dimensions for your equipment. The YWZ8-200/E23, for instance, has an external dimension of 430 mm (A), 90 mm (b), and 160 mm (C), making it compatible with a range of machines.
   • Connect the hydraulic system properly to maintain the necessary oil flow. The hydraulic connections for the YWZ8-300/E30, with its larger dimensions (e.g., 500 mm for A and 140 mm for b), may require additional attention for optimal performance.
2. Komisioning:
   • Before operation, check the hydraulic system to ensure the oil pressure and flow rates are within the proper range. For example, the YWZ8-300/E30, with a braking torque of 200-320 Nm, requires sufficient hydraulic pressure for effective operation.
   • Adjust the clearance between the friction pads and drum to the recommended specifications (e.g., 0.7 mm for the YWZ8-200/E23).
   • Test the brake under load conditions to ensure it achieves the expected braking torque (e.g., 135-200 Nm for YWZ8-200/E23).
3. Operasi:
   • During operation, the hydraulic system adjusts the oil flow to provide the necessary braking force. The YWZ8-300/E30, with its 200-320 Nm braking torque, ensures reliable braking performance even under heavy load conditions.
   • Monitor the hydraulic oil’s cleanliness and level. For models like YWZ8-200/E23 and YWZ8-300/E30, maintaining oil quality is critical for consistent braking performance.
4. Pemeliharaan dan Perawatan:
   • Inspect the wear condition of friction pads regularly. In the case of the YWZ8-200/E23, if the pads are worn out, they should be replaced to ensure braking efficiency.
   • Periodically check the hydraulic system for leaks and ensure the oil remains clean. This is especially important for larger models like the YWZ8-300/E30, where hydraulic pressure plays a key role in maintaining braking torque.
   • Bersihkan rem dan komponen di sekitarnya untuk mencegah kotoran atau serpihan mempengaruhi kinerja.
