Brazil hydraulic cylinder,swager cylinder manufacturer,swager cylinder(Brazil swager cylinder,produced by Hengyu Hydraulic Cylinder Factory)
swager cylinder are widely used in Brazil,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed swager cylinder for customers from Brazil.
Regular maintenance of the swager cylinder includes: regular tightening, swager cylinder fastening screws and gland screws, swager 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 swager cylinder once a year. Clean regularly, the swager cylinder is cleaned every other year, and the seals are replaced while cleaning.
The method of sleeve swager cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the swager cylinder can be significantly improved by rolling in the finishing of the inner holes of the swager cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
The viscosity of the working oil used in the swager 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.
Before the swager cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.
What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.
When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
