What is the reason why the speed of the cutting machine slows down and the pressure drops? [Ponse cutting machine]
Analysis of causes for speed reduction and pressure drop of cutting machine.
1, single head electromagnetic valve head failure;
2, control the single head valve J2 relay burned;
3. The seal ring of the oil cylinder is aging.
4. The valve core of the solenoid valve is worn seriously.
5, the viscosity of pressure oil is reduced.
