Lubrication Maintenance

Moving parts of the machine are equipped with lubrication devices and lubrication points.

Fixed-Resistance Lubrication System

This system is configured with damping distributors. When the lubrication pump operates, pressure is generated in the oil lines from the pump outlet to each distributor due to the damping effect. When this pressure exceeds the damping differential, the lubricant continuously overcomes the resistance and flows to each lubrication point until the lubrication cycle ends. Varying orifice sizes in the distributors ensure precise oil distribution according to the specific needs of each lubrication point. If the line pressure fails to reach the pressure relay's set value during the lubrication cycle, the machine will trigger an alarm, indicating required inspection or repair.

Quantitative Pressure Lubrication System

This system uses metered-pressure distributors. During pump operation, pressure builds up in the distributors, forcing a precise amount of lubricant from the upper chamber to each lubrication point. When line pressure reaches the relay's setpoint, the pump stops and the lubrication timer starts. Distributors then depressurize and automatically refill from the main supply line. This cycle repeats until the total lubrication time elapses. Different distributor displacements ensure accurate oil allocation to each point. System failure is indicated if the pressure doesn't reach the required value during operation.

Critical Maintenance Requirements:

• Strictly prevent contamination from water, steam, dust, or direct sunlight

• Conduct regular inspections of all lubrication points

• Ensure adequate lubrication duration for complete coverage

• Maintain proper oil levels in the reservoir

Parameter Settings:
Lubrication intervals and duration are pre-configured for optimal performance. While users may adjust intervals based on operating conditions (shorter intervals during first 6 months, longer for larger machines), avoid modifying other parameters. For quantitative pressure systems, set sufficient lubrication time to allow proper pressure buildup and prevent false alarms from short cycles. Address any lubrication issues immediately and monitor system performance regularly.
