Reasons for the low speed of the hydraulic cylinder of the press
The hydraulic cylinder is an important executive element in the press equipment. Under the high-speed and high-pressure operation of the hydraulic system, the load capacity of the hydraulic cylinder also increases, resulting in elastic or elastic-plastic deformation and expansion of the inner diameter of the cylinder, thereby causing the cylinder wall of the hydraulic cylinder to expand. Expansion occurs, causing leakage of the hydraulic system to affect the normal operation of the four-column hydraulic press. So what are the reasons for the low speed of the hydraulic cylinder of the press?
1. Low-speed creeping due to uneven friction of the guiding elements in the hydraulic cylinder of the press. It is recommended to use metal as the guide support. If non-metallic support rings are used, it is recommended to use non-metallic support rings with good dimensional stability in the oil, especially the thermal expansion coefficient should be small. In addition, the thickness of the support ring must be strictly controlled. uniformity of duty and thickness.
2. The hydraulic cylinder of the press has low-speed creeping caused by mixing gas. In this situation, the purpose of exhausting can be achieved by repeatedly operating the hydraulic cylinder. If necessary, an exhausting device can be provided in the two chambers of the pipeline or hydraulic cylinder to exhaust the hydraulic system of the four-column press.
3. Low-speed crawling caused by improperly designed gaps in the hydraulic cylinder of the press. The sliding cooperation gap between the piston and the cylinder body, the piston rod and the guide sleeve in the hydraulic cylinder can be correctly planned.
The sharing of the reasons for the low operating speed of the hydraulic cylinder of the hydraulic press is here. The low operating speed of the hydraulic cylinder causes the leakage to affect the normal operation of the hydraulic press, so the operator must operate according to the rules in daily life.
