Mexico hydraulic cylinder,swager cylinder manufacturer,swager cylinder
(Mexico swager cylinder,produced by Hebei Hengyu company）
swager cylinder are widely used in Mexico，because of no transmission clearance，powerful torque，excellent temperature resistance.So our company has designed swager cylinder for customers from Mexico.
The internal leakage of the swager cylinder is an important indicator to measure the quality of the swager cylinder: the internal leakage of the swager cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the swager cylinder, so that the swager cylinder can not accurately and stably stop in a certain position of the swager cylinder, so it is one of the main indicators of the swager cylinder.
How to determine the working pressure of the swager cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, swager cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.
When the swager 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 swager cylinder is mainly composed of body, piston, piston rod, swager cylinder head, swager cylinder bottom, piston rod head and related auxiliary devices. The piston divides the swager cylinder into two chambers, and moves reciprocally in the swager 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 swager cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the swager 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 swager 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 swager cylinder bottom and the swager cylinder head is serious, so the buffer deceleration should be set at both ends of the swager cylinder The working medium of the swager cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; swager 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 swager cylinder: The buffer structure of the swager cylinder is to prevent the piston from colliding with the swager cylinder head at the end of the stroke.
Why is a light cylinder less productive than a heavy cylinder at the same oil pressure?
f=ps Under the same pressure, the larger the area, the greater the output, but the maximum pressure can not exceed the system engineering pressure of the cylinder!
What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.
