Common faults and maintenance methods of aluminum profile extrusion machines
Common faults and maintenance methods of aluminum profile extrusion machines
Ask; What is the reason for the slow starting pressure of the aluminum alloy profile extruder?
Check to see if the duty current when the push rod enters is large. If not, you can adjust it higher and try it. Check if the secondary transformer is too small. Moderately adjust the height to check whether it is too early to transfer to work
Check whether the reaction rate of the inflation valve is fast
Ask; Push the rod in and adjust the current amount a little higher, and the dual pump proportional solenoid valve is fully opened to pressurize 210MP after the main cylinder exhaust pipe is 110MP
After the process is changed, the front is slow and the rear is fast, making it more noticeable to make thick materials. The disassembly of the two quick release cylinders verifies that the Glee ring is intact and free of leakage. The pressure relief valve and the two flow relief valves are all new. The independent pressure rise of the flow relief valve reflects the rapid setting of 240MP. Are there any other factors? Answer:; In that case, it is likely that the inflation valve is not closed quickly enough. Ask; Aluminum alloy profile extrusion machine is a large-scale mechanical equipment for pressing aluminum alloy profiles. Extruded aluminum and aluminum alloy profiles are all round rods, which are subject to heavy loads and high levels of damage during work. How do you usually protect and maintain machinery and equipment?
Answer:;
Before feeding, it is necessary to check the purity of raw materials, and it is not allowed to let dirty things enter the equipment to prevent damage to the equipment.
2. Generally, check the wetting level of the rotating position to prevent damage caused by untimely wetting.
The aluminum alloy profile extrusion machine must achieve the required heating temperature in the forming mold and barrel before carrying out the actual operation of seasoning extrusion, reducing the working intensity of the equipment when pressing aluminum profiles.
The rotation speed ratio of the screw rod needs to be gradually increased from low to high, and the time for high rotation speed in the cylinder is less than 2-3 minutes.
5. Pay more attention to the operation status of the main motor of the extruder during the international idle running time of the screw rod in the material barrel.
6. For the motor of the extruder, it is necessary to pay attention to its operating status in a timely manner, and avoid long-term high load conditions, which will reduce its service life.
7. The connection condition of each component should be well inspected, and the fixed anchor bolts should be operated according to the standard actual operation to check whether there is any peeling condition.
8. Each smooth position needs to be checked by each shift to see if sufficient wetting has been carried out.
The rolling bearing temperature of the aluminum alloy profile extruder should not exceed 50 ℃.
10. Finished products on the screw rod should be immediately cleaned and tidy.
11. After completing daily work, immediately remove the residue left by the aluminum alloy extrusion machine after pressing, and clean the packaging mold, screw rod, and machine barrel.
To ensure that there are no abnormalities in the aluminum profile extrusion machine, the maintenance and care of ordinary equipment is particularly critical
Frequently occurring problems include frequent outages (especially when there is no power), and common equipment failures (common failures due to equipment problems). Let's learn how to maintain the machinery and equipment
1. Daily medical care must be closely followed, and mechanical equipment must be cleaned to a certain extent.
2. Clean the filter screen of the gasoline pump on time, and maintain the gasoline pump paddle and pump housing. Properly use a thermometer to check the difference between the ambient temperature of the gasoline pump and the new gasoline pump, so as to understand the relative leakage status of the gasoline pump. No matter how good the sealing standard of the suction and delivery pipes is, the gasoline pump has certain suction conditions, so it is necessary to pay attention to the oil in the oil tank.
3. Overhaul requires accumulated work experience. Usually, use the operating console to handle the temperature of the oil circuit board of the magnetic induction machine equipment.
4. If a problem occurs, immediately record the maintenance to prevent the same common fault from occurring next time. Having a certain understanding of the speed of the machine and equipment can prevent the probability of maintenance.
5. It is important to maintain the cleaning of the engine oil. If there are holes on the surface of the email, it should not be repaired properly. The special requirement is that the hole of the return oil pipe penetrating the outer surface of the oil tank must be sealed with rubber sleeve.
6. Frequently detect the working pressure and natural pressure of the equipment table, and use an ammeter to measure the three current quantities of the motor. Maintain all normal operation of the motor to prevent sudden shutdown due to burning or excessive weight of the motor.
