In the planning of hydraulic systems, it is often necessary to first determine the working speed of the hydraulic cylinder and then calculate the required flow rate. When planning, it should be noted that the rated flow rate of the hydraulic pump of the carpenter edge banding machine should be greater than the required flow rate of the hydraulic cylinder, which can compensate for losses caused by leakage.However, hydraulic pumps with high flow rates should not be used, as this not only accelerates the speed of the hydraulic cylinder, but also causes a large amount of oil to be pulled out of the overflow valve during throttling and speed regulation, causing an increase in the mooring temperature. The change in mooring temperature will also affect the stability of hydraulic cylinder movement.

In a hydraulic system with multiple hydraulic cylinders, if it is a sequential motion, the hydraulic cylinder with the highest required flow rate should be used when selecting the rated flow plate of the hydraulic pump. If multiple cylinders move together, the rated flow rate of the hydraulic pump should be greater than the total required flow rate of the hydraulic cylinders that move together.

Selection of Safety Factor for Hydraulic Cylinder of Carpenter Edge Sealing Machine

The selection of safety factor for hydraulic cylinders directly affects the quality and economy of hydraulic cylinders. In the strength calculation of hydraulic cylinder components, planners generally strictly follow the usage conditions of the formula and strive to obtain accurate calculation results. However, if the safety factor is not properly selected, the calculated value will be unreasonable. There is no mandatory requirement for selecting the safety factor, but it is necessary to choose a smaller value as much as possible while fully ensuring safety. If the safety factor is too high, not only will it cause unnecessary waste and increase costs, but also the planned hydraulic cylinder has a large external size and a large component, often unable to meet the requirements of working machinery. But the safety factor cannot be too low to avoid accidents.
