How does the common malfunction of the plastic cutting machine be excluded?


How does the common malfunction of the plastic cutting machine be excluded?

Exorbitant lubricating oil temperature is too high.

1. the oil pump is damaged, and the internal parts wear and produce heat when rotating at high speed.

2. the internal leakage of the oil pressure assembly, such as the failure of the directional valve or the damage of the sealing ring, causes the high-pressure oil to flow through the small space to generate heat.

3. improper pressure regulation, the hydraulic system is overheated for a long time.

The noise of the plastic cutting machine is great.

1. the hydraulic oil in the tank is insufficient, the oil pump inhaled air or the oil filter is blocked by the dirt, which will cause the oil pump to lack oil, which causes the bubbles in the oil liquid to discharge the impact blade and produce noise. The solution is to check the amount of oil, prevent the air from inhaling and clean the filter.

2. hydraulic oil viscosity is high, increase flow resistance, need to replace the appropriate hydraulic oil.

3. due to the damage of the bearing or blade of the oil pump or motor, the concentricity deviation of the coupling causes noise, and the concentricity must be adjusted to replace the parts.

The 4. direction valve response failure, but the function is still in, such as the valve heart wear, internal leakage, burr blocking, movement is not flexible, the electromagnetic valve failure due to the current can also produce noise. The solution is to clean the valve core or replace the new parts. The current must be stable and sufficient.

5. hydraulic components damage or oil pipeline blockage, making hydraulic oil noise when high-speed flow.

6. mechanical parts failure, machine parts lubrication is insufficient, parts loose, we should find out the reasons for fastening or replacement.

Plastic cutting machine press plate not down or down after not reset:

1. the switch has a problem, check or replace.

2. oil tank is insufficient or oil pipe leak, oil or tighten tubing connection.

3. the solenoid valve can not be reset, repair or replace.

4. relay contact is not good, main oil circuit can not switch, check the line.

The cutting pressure of the plastic cutting machine is not enough.

1. the oil pump is damaged or the oil inlet is blocked, and the oil cylinder leaks.

2. the micro switch is too slow or faulty, and it is adjusted to make it touch or replace it at about 10MM before the cutting point.

3. malfunction of the solenoid valve, repair the axis of the solenoid valve.

4. the circulating oil of the tank is not enough. Replenish the circulating oil so that the oil level exceeds the oil screen.
