Britain hydraulic cylinder,self-locking hydraulic cylinder manufacturer,self-locking hydraulic cylinder(Britain self-locking hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
self-locking hydraulic cylinder are widely used in Britain,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed self-locking hydraulic cylinder for customers from Britain.
The piston rod and guide sleeve function of the self-locking hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
The wear of the hard chromium plating layer of the self-locking hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
self-locking hydraulic cylinder and hydraulic station selection: Select the type and structure of the self-locking hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the self-locking hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the self-locking hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the self-locking hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the self-locking hydraulic cylinder, the diameter of the piston and the piston rod.
When the piston speed of the self-locking hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the self-locking hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.
