6. Structure:This standard cylinder is equipped with 17 types of cylinder diameters(40、50、63、80、90、100、110、125、140、150、160、180、200、220、250、280、320)in accordance with two speed ratios to reach 34 stipulations.Divided into gap buffer and  buffer structurewithout gap.The cylinder head and the cylinder tail can also have a one-way bleed valve, which can be used for quick start with a buffer cylinder and for deflation.The rod dust seal has a replaceable structure for on-site maintenance. The piston rod is coated with protective hard chrome, which is dust-proof, rust-proof, anti-corrosive and wear-resistant.

7. Installation connection: in line with the international ISO6020/1-1981 series hydraulic cylinder installation connection size.Basic types of different cylinder bores include, front and rear rectangle flanges, front and rear mounting flanges, front and rear round flanges, front, middle and rear hinge shafts, head single earrings, axial and radial tripods total 13 Installation forms.In addition to the axial tripod type, the dimensions of mounting connection are in accordance with I6020, 1-1981.

Ordering instruction

1.When the heading earrings are selected for the smelting standard hydraulic cylinder, they should be ordered separately.

2.Earring number E contains two forms of E1 and E2. E1 is a joint bearing, E2 is a jointless bearing (with a bushing), and the installation dimensions are the same.

3.The cylinder diameter D and the rod diameter d should be indicated when ordering

Instructions

1.The determination and selection of the cylinder bore, rod diameter and pressure of the hydraulic cylinder must take into account the pressure of the hydraulic system pressure source and the loss of the system. The pressure control and adjustment are determined by the hydraulic system pressure regulating valve.

2.Before the hydraulic cylinder is operated, it must be reciprocated several times with low pressure (higher than the starting pressure), and the one-way venting valve at both ends is alternately opened to remove the gas in the cylinder before normal operation can be performed. A combination seal must be fastened between the inlet and outlet ports to prevent hydraulic oil leakage.
