The hydraulic system is the core of a hydraulic tire baler, so correct starting and shutting down procedures are critical to protect equipment life, ensure operational safety, and avoid hydraulic component damage. These procedures need to follow a logical sequence, combining pre-checks and step-by-step operations.
Correct Starting Process
Before starting the hydraulic system, a comprehensive pre-inspection is essential. First, check the hydraulic fluid level: open the fluid reservoir cap and confirm the fluid reaches the recommended level . If the level is too low, add the specified type of hydraulic fluid—mixing different types of fluid can damage seals and clog the system. Next, inspect hydraulic hoses and connections for cracks, leaks, or loose fittings; even small leaks can lead to pressure loss and inefficient operation. Then, verify that all safety guards around the hydraulic cylinders and compression chamber are in place and secured, as moving hydraulic parts pose injury risks. Finally, test the emergency stop button to ensure it can immediately cut power if needed.
After pre-inspection, start the system step by step. First, turn on the main power switch of the baler, but do not activate the hydraulic motor immediately. Allow the system to stand for a short time to let the hydraulic fluid warm up slightly—cold fluid has high viscosity and can cause excessive pressure on the pump when the motor starts. Then, start the hydraulic motor at low speed . Let the motor run idle for a few minutes to circulate the fluid and build up pressure gradually. During idle time, observe the pressure gauge to ensure pressure rises smoothly without sudden surges. Meanwhile, check for abnormal noises from the motor or pump, which may indicate internal wear or air in the system. If everything is normal, slowly adjust the motor to the working speed and activate the hydraulic control valve to test the movement of the compression plate—move it forward and backward slightly to confirm smooth operation before formal use.
Correct Shutdown Process
Shutting down the hydraulic system also requires a systematic approach to avoid sudden pressure release or fluid backflow. First, stop any ongoing compression operations: retract the compression plate to its original position using the control panel, ensuring it is not in contact with tires or other objects. Then, reduce the hydraulic motor speed to idle and let it run for a short time—this helps cool the system and circulate residual heat from the fluid, preventing overheating-related damage. Next, close the hydraulic control valves to cut off fluid flow to the cylinders, ensuring the system is in a pressure-relieved state. Check the pressure gauge to confirm pressure drops to a safe level; if pressure remains high, slowly open the pressure relief valve to release excess pressure gradually—sudden pressure release can damage hoses and valves.
After pressure relief, turn off the hydraulic motor first, then switch off the main power supply. Conduct a post-shutdown inspection: check for any new leaks or hose damage caused by operation, and wipe down the hydraulic reservoir cap and control panel to remove dust and debris. If the baler will not be used for a long time, cover the hydraulic hoses and connections with protective caps to prevent dust and moisture from entering. Additionally, record the startup and shutdown status in the equipment log to facilitate subsequent maintenance.
In summary, correct starting relies on pre-inspection and gradual pressure buildup, while correct shutdown focuses on pressure relief and system cooling. Following these procedures ensures the hydraulic system operates safely and durably, supporting the stable work of the hydraulic tire baler.
