The hydraulic cylinder cylinder design sense

Hydraulic cylinder cylinder measuring is mainly the following aspects: installation size, cylinder diameter and stem diameter, stroke, and external special structure. There are signs to record the sign all the content, the belt displacement sensor or close to switch, to record its model. Internal structure of cylinder body only for reference, generally don't have to copy ( Internal structure according to the factory processing capacity design) 。 Working temperature, working medium. A, appearance design. Shape structure with original structure, as far as possible to make a change if processing difficulties you must communicate with the customer agreement, customer sign when necessary. 。 If the measurement data is not very accurate, to remove the installation size deviation ( Ensure that can be installed on the device) , take on deviation ( Ensure that can work in place) 。 Second, the internal structure design design purpose: on the basis of field work temperature, working medium and the processing conditions. Based on mechanical design manual, calculate the size of the internal structure. 。 The selection of seal must be according to the field work temperature, environmental pollution situation, the working medium to choose. Cannot use polyurethane sealing water glycol medium. 。 Oil cylinder of the cylinder head with v-shaped sealing as far as possible, so that we can make up for the groove machining error of the finish. 。 Sealing groove size strictly according to the design manual for design. 。 He is generally selected cylinder piston sealing ring and guide belt, his circle of high temperature resistant and stain resistance is better. 。 Cylinder seal generally choose Japan NOK series, must not use domestic oil cylinder seal, otherwise the cylinder starting resistance is too large, action is not smooth and even does not work. 。 Oil cylinder cylinder head between the bottom of the cylinder and the cylinder seal o-rings, had better add baffle ring, so that we can make up for the machining error. 。 Cylinder and the cylinder head trying not to be placed in the bottom of the cylinder and connection with the method of welding, because the welding deformation will cause the cylinder, the available threaded connection or other connection.
