Sweden hydraulic cylinder,lifting platform cylinder manufacturer,lifting platform cylinder(Sweden lifting platform cylinder,produced by Hebei Hengyu company)
lifting platform cylinder are widely used in Sweden,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed lifting platform cylinder for customers from Sweden.
lifting platform cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the lifting platform cylinder is placed for a period of time, the lifting platform cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
If the piston rod and lifting platform cylinder are stuck or the lifting platform cylinder is blocked, at this time, no matter how to operate, the lifting platform cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the lifting platform cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
If the lifting platform cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.
The lifting platform cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the lifting platform cylinder, bite. Elimination method: When installing the lifting platform cylinder, ensure that the axis position of the lifting platform cylinder is consistent with the direction of movement; Make the load borne by the lifting platform cylinder as far as possible through the lifting platform cylinder axis, to avoid the phenomenon of eccentricity.
What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.
