1.Common faults in the operation of aluminum profile extrusion machine
1.1 The pressure of the aluminum extruder is slow
When the rod enters, see if the proportional current is maximum. If not, try turning it on. See if the secondary voltage adjustment is too small. Try to see if you've changed jobs prematurely.
The following is a solution to slow pressure in aluminum extrusion machines.
The check valve responds fast enough
The water inlet flow of the push rod has been slightly adjusted, and the double pump proportional solenoid valve has a full open pressure of 210MP and the main cylinder exhaust is 110MP. Due to its thicker material, there is no leakage in the greer ring of the two fast forward cylinder open check valves, the safety valve and the two flow valves are new, and the single pressure response of the benefit flow valve is set to 240MP.
The filling valve may not close fast enough
Aluminum extrusion machine is a heavy equipment for extruding aluminum profiles. Extrusion of aluminum and aluminum strips, heavy workload, high degree of wear, need to maintain the equipment regularly? Before feeding, check the purity of the raw materials, and do not let foreign matter enter the machine to avoid damaging the machine.
1.2 Overheating of the aluminum extrusion machine
Overheating in aluminum extrusion machines can result from several issues, and addressing them promptly is crucial to maintaining efficiency and preventing damage.
Here are common reasons for overheating.
- Inadequate Cooling Systems. Insufficient cooling capacity or malfunctioning cooling systems can lead to overheating.
- High Friction. Excessive friction between the billet and the die can generate excessive heat.
- Improper Lubrication. Lack of or improper lubrication in the machine components can cause increased friction and heat.
- Overloading. Operating the machine beyond its recommended capacity can result in overheating.
- Faulty Components. Worn-out or malfunctioning components, such as bearings, can cause overheating.
- Electrical Issues. Electrical faults, such as short circuits or malfunctioning electrical components, can generate excessive heat.
- Ambient Temperature. High ambient temperatures can exacerbate the overheating issue, especially if the machine is not designed to operate in such conditions.
- Clogged Cooling Channels. Debris or buildup in the cooling channels can impede the flow of coolant, leading to overheating.
Here are the corresponding repair methods for overheating.
Upgrade or Maintain Cooling Systems
Ensure that the cooling system is adequate for the machine’s capacity. Regularly maintain and upgrade the cooling system as needed. Clean cooling channels and replace any malfunctioning components of the cooling system.
Reduce Friction
Use appropriate dies and ensure that they are properly aligned and maintained to reduce friction. Utilize high-quality, heat-resistant lubricants to minimize friction.
Proper Lubrication
Regularly lubricate all moving parts with suitable lubricants. Follow the manufacturer’s recommendations for lubrication intervals and types of lubricants.
Avoid Overloading
Operate the machine within its specified limits. Avoid pushing the machine beyond its capacity.
Replace Faulty Components
Regularly inspect and replace worn-out or damaged components, such as bearings, seals, and other critical parts.
Address Electrical Issues
Regularly inspect the electrical system for any faults. Replace damaged wires, fuses, or other electrical components. Ensure that the electrical system is properly insulated and grounded.
Control Ambient Temperature
If possible, control the ambient temperature around the machine. Use air conditioning or ventilation systems to maintain a stable operating environment.
Regular Maintenance
Implement a regular maintenance schedule to inspect, clean, and replace components as needed. Keep a log of maintenance activities to identify and address recurring issues promptly.
2. Operation manual for aluminum profile extrusion machine
Check the lubrication of the transmission to avoid lubrication in place and wear.
In order to carry out seasoned extrusion operations and reduce the working intensity of the extruder machine, the aluminum extruder must reach the specified heating temperature in the mold and cylinder.
The speed of the screw should be gradually increased from low to high, and the idle time of the drum should be less than 2-3 minutes.
When the screw is idling in the cylinder, pay attention to the working state of the main motor of the extruder.
The extruder motor should pay attention to its working state at any time to avoid long-term overload and shorten the service life.
Check the connection of each part, bolt it according to the standard operation, and check whether there is any loosening.
Each lubricated part should be inspected in every session to see if it is fully lubricated.
The bearing temperature of the aluminum extruder should not exceed 50°C.
The residue on the screw should be cleaned up in time.
After work every day, the residue extruded by the aluminum extruder, packaging mold, screws, and machine should be cleaned in time.
In order to prevent the failure of the aluminum extruder, the maintenance and maintenance of the equipment is very important.
3.How to maintain the aluminum profile extruder?
Common problems include frequent downtime (especially when there is no power supply) and machine failures (failures due to machine failures). Let's see how the equipment is maintained.
Daily maintenance must be followed, and the machine must maintain a certain degree of cleanliness.
Clean the oil pump filter regularly to protect the oil pump blades and pump body. Use the thermometer correctly, check the temperature difference between the oil pump and the new oil pump, and understand the relative leakage of the oil pump. Regardless of the tubing seal condition, the pump has a certain pumping situation, so pay special attention to the oil tank.
Maintenance is the accumulation of experience, and multiple machines are usually used to manually detect the temperature of the valve body.
Record the maintenance problem in time to prevent the same failure next time, and have a certain perception of the speed of the machine, so as to avoid the possibility of overhaul.
If there are holes on the surface of the mailbox, be sure to keep the hydraulic oil clean. The holes in the surface of the fuel tank must be rubber-sealed.
The pressure and atmospheric pressure of the motor should be checked frequently, and the three-strand current of the motor should be used to protect the motor from abnormal operation, so as to avoid the motor from burning out or sudden shutdown of the motor due to motor overload.
