(Slovenia electric forklift hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
electric forklift hydraulic cylinder are widely used in Slovenia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed electric forklift hydraulic cylinder for customers from Slovenia.
electric forklift hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
The electric forklift hydraulic cylinder is not the same as the electric forklift hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the electric forklift hydraulic cylinder can not be used as a high-power power component, but the electric forklift hydraulic cylinder can be used as a relatively large power component, or the electric forklift hydraulic cylinder system can be used.
When the electric forklift hydraulic cylinder is installed, the piston and the electric forklift hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the electric forklift hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the electric forklift hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized electric forklift hydraulic cylinders, only careful and careful operation can be avoided.
electric forklift hydraulic cylinder use should try to avoid sealing belt into the electric forklift hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the electric forklift hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the electric forklift hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
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.
How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
