America hydraulic cylinder,stainless steel cylinder manufacturer,stainless steel cylinder(America stainless steel cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stainless steel cylinder are widely used in America,because of smooth movement,high work efficiency,clever hydraulic energy conversion.So our company has designed stainless steel cylinder for customers from America.
The stainless steel cylinder is mainly composed of body, piston, piston rod, stainless steel cylinder head, stainless steel cylinder bottom, piston rod head and related auxiliary devices. The piston divides the stainless steel cylinder into two chambers, and moves reciprocally in the stainless steel cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the stainless steel cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the stainless steel cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the stainless steel cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the stainless steel cylinder bottom and the stainless steel cylinder head is serious, so the buffer deceleration should be set at both ends of the stainless steel cylinder The working medium of the stainless steel cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; stainless steel cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the stainless steel cylinder: The buffer structure of the stainless steel cylinder is to prevent the piston from colliding with the stainless steel cylinder head at the end of the stroke.
When the stainless steel cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the stainless steel cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.
The viscosity of the working oil used in the stainless steel cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
Regular maintenance of the stainless steel cylinder includes: regular tightening, stainless steel cylinder fastening screws and gland screws, stainless steel cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the stainless steel cylinder once a year. Clean regularly, the stainless steel cylinder is cleaned every other year, and the seals are replaced while cleaning.
What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.
What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.
