(Slovakia stainless steel cylinder,produced by Hengyu Hydraulic Co., Ltd）
stainless steel cylinder are widely used in Slovakia，because of no need for deceleration device，long service life，smooth movement.So our company has designed stainless steel cylinder for customers from Slovakia.
When the stainless steel cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
The internal leakage of the stainless steel cylinder should be prevented when the stainless steel cylinder is used. The internal leakage of stainless steel cylinder includes the leakage caused by excessive wear of stainless steel cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.
When the oil pressure of the stainless steel cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
We can not just consider the price and ignore the quality when we purchase the stainless steel cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the stainless steel cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the stainless steel cylinder is not required.
How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.
What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
