UAE hydraulic cylinder,stainless steel cylinder manufacturer,stainless steel cylinder
(UAE stainless steel cylinder,produced by Hebei Hengyu company）
stainless steel cylinder are widely used in UAE，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed stainless steel cylinder for customers from UAE.
The assembly work of the stainless steel cylinder has a great impact on the quality of the stainless steel cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
The pressure of the sliding surface of the stainless steel cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the stainless steel cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
When installing the stainless steel cylinder pipe, the pipe should be cleaned after installation, and should not pass through the stainless steel cylinder block, and the by-pass pipe must be installed in front of the oil port of the stainless steel cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the stainless steel cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the stainless steel cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
The stainless steel cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure stainless steel cylinder can use 20 steel pipe, and the high pressure stainless steel cylinder can use 45 steel pipe.
How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.
What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.
