Kenya hydraulic cylinder,swager cylinder manufacturer,swager cylinder
(Kenya swager cylinder,produced by Hengyu Hydraulic Co., Ltd）
swager cylinder are widely used in Kenya，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed swager cylinder for customers from Kenya.
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.
The cavitation of the swager cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the swager cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
The quality of the swager cylinder can not be ignored in the purchase of the swager cylinder. The swager cylinder is the main component of the swager cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. swager cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of swager cylinder is deep hole processing, which has always troubled the processing personnel.
swager cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.
How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).
How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.
