Estonia hydraulic cylinder,stainless steel cylinder manufacturer,stainless steel cylinder
(Estonia stainless steel cylinder,produced by Hengyu Hydraulic Co., Ltd）
stainless steel cylinder are widely used in Estonia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed stainless steel cylinder for customers from Estonia.
The commonly used buffer structure of the stainless steel cylinder is composed of a piston boss and a stainless steel cylinder head groove. When the piston moves close to the stainless steel cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
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.
The piston rod and guide sleeve function of the stainless steel 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 stainless steel cylinder is not the same as the stainless steel cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the stainless steel cylinder can not be used as a high-power power component, but the stainless steel cylinder can be used as a relatively large power component, or the stainless steel cylinder system can be used.
How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
