Important causes of ups and downs of the foil winding machine: The screw that adjusts the pressure is caused by vibration and preventing the loose nut from the stress. For changes, sometimes the valve core card will be killed; the main valve core rolling is blocked and the damping hole is blocked; The damping hole is large and does not have a damping effect; the liquid control valve regulates the twist spring bending, which makes the valve core and the valve seat not touch well, and the damage is not uniform. A amorphous three -dimensional rolling iron heart, non -crystal three -dimensional high and low pressure integrated machine

Solution: Clear the oil tank, pipeline, and the pipelines with a comprehensive pipeline of gear oil on time; if there are already filtering devices in the pipeline, the fascinating component should be improved, or the filtering accuracy of the second -dimensional component should be replaced. Disassemble and clean the valve components to replace the clean gear oil; mechanical and electrical maintenance or replacement parts that do not meet the requirements; moderately change the diameter of minimum vibration reduction.

System software pressure cannot be completely added

The important reasons why the pressure cannot be added to the system software:

1. Common faults of the main valve core: The main valve core damping hole is blocked. The gap in the valve is not very good, and the main valve core is stuck when the seat is opened; the main valve core rectangular spring is broken or bent, so that the main valve core cannot be calibrated.

Solution: Disassemble and allocate valve to clean up the damping holes and reassemble; overrun or replace the hydraulic oil; tighten the single -flow valve fastening screw to replace the broken twist spring.

2. Common faults of liquid control valves: regulate twisted spring breaks or not installed; cone valves or rollers are not installed; cone valve rupture.

Solution: Replace the damage or reinstall the parts to restore the liquid control valve to work.

3. Common faults of hydraulic oil pumps: The linked keys of the hydraulic oil pump fall or flip; the gap between the rolling surface is too large; the leaves of the axial plunger pump are stuck in the motor rotor; Dedicated by high frequency cycle time load, tiredness and love or break.

Solution: Disassemble and clean the axial plunger pump; correct the wrong position; replace the fracture spring.

System software pressure is not too high

An important reason why system software is not too high:

1. Common faults of the main valve core: the main valve pyramid surface is damaged or non -round, the valve seat cone surface is damaged or non -round; the cone surface is dirty and sticky; The same heart; the main valve core and the valve seat are not very good at each other. Poor, the screw screws fall off.

Solution: Replace or electromechanical maintenance valve body or assignment valve and valve seat; clean up the speed regulating valve to make it cooperate with each other or replace the device; Make sealing excellent.

2. The liquid control valve regulates the twist spring bending or too short, too soft, resulting in a closed difference between the cone valve and the valve seat.

Other common faults

If the cone valve or the main valve core is too damaged, or the exposure to the sudden exposure will also cause too much internal leakage and even harm the normal operation.
