As an important construction equipment, the daily maintenance and care of portable hydraulic punching machines are crucial for the equipment's lifespan, performance, and construction safety.
I. Precautions for Daily Maintenance
Hydraulic System Inspection
Hydraulic Oil Level and Quality: Check the hydraulic oil level every day to ensure sufficient oil; observe the color and transparency of the hydraulic oil. If it appears turbid, has an odor, or contains impurities, it needs to be replaced immediately.
Hydraulic Pipeline: Check whether the hydraulic pipeline is leaking, damaged, or aging, especially at the joints. If abnormalities are found, tighten or replace the seals in a timely manner.
Oil Temperature Control: The operating temperature of the hydraulic system should be kept within a reasonable range (usually 40°C - 60°C) to avoid high temperatures causing oxidation and deterioration of the hydraulic oil.
Mechanical Parts Inspection
Punching Dies and Tools: Check the wear of punching dies and tools, regularly clean chips and oil stains to prevent jamming; severely worn dies need to be replaced in a timely manner.
Fasteners: Check whether the bolts and nuts of various parts of the equipment are loose, especially key parts such as hydraulic cylinders and frames, to ensure a firm connection.
Lubrication and Maintenance: Lubricate the moving parts (such as guide rails and bearings) with special grease or hydraulic oil to reduce wear.
Electrical System Inspection
Power Supply and Cable: Check whether the power cord is damaged and whether the plug is in good contact to avoid leakage or short circuits.
Control Elements: Check whether the control elements such as buttons, switches, and indicator lights are working properly to ensure flexible and reliable operation.
Grounding Protection: Ensure that the equipment is well grounded to prevent static electricity or leakage from causing safety accidents.
Cleaning and Rust Prevention
Equipment Cleaning: After daily work, clean the oil, dust, and chips on the surface of the equipment to keep the equipment clean.
Rust Prevention: Apply anti-rust oil to metal parts, especially for equipment that has not been used for a long time, and take anti-rust measures.
Safety Device Inspection
Safety Valve and Limit Switch: Check whether the safety devices such as safety valves and limit switches are working properly to ensure that the equipment can be shut down in time under abnormal conditions.
Protective Device: Check whether the protective cover, guardrail, etc., are intact to prevent operators from contacting dangerous parts.
II. Maintenance Cycle Recommendations
Daily Maintenance
Check the hydraulic oil level, oil temperature, pipeline, and fastener status.
Clean the oil and chips from the equipment surface.
Inspect the electrical system and safety devices.
Weekly Maintenance
Refill or replace the hydraulic oil (depending on the oil quality).
Inspect and lubricate the moving parts.
Inspect the wear of the punching die and tool.
Monthly Maintenance
Fully inspect the hydraulic system, including filters, seals, etc.
Inspect the insulation performance of the electrical system and clean the control components.
Perform a comprehensive cleaning and rust prevention treatment on the equipment.
Quarterly Maintenance
Replace the hydraulic oil and filter element.
Inspect the performance of key components such as hydraulic cylinders and pump stations.
Calibrate safety devices and limit switches.
Annual Maintenance
Overhaul the equipment and replace severely worn parts.
Perform a pressure test and leak check on the hydraulic system.
Perform a comprehensive inspection and upgrade of the electrical system (if necessary).
