(Austria moving truck hydraulic cylinder,produced by Hengyu Group）
moving truck hydraulic cylinder are widely used in Austria，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed moving truck hydraulic cylinder for customers from Austria.
Piston moving truck hydraulic cylinder is widely used in hydraulic transmission. When the moving truck hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the moving truck hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the moving truck hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.
If the seal of the moving truck hydraulic cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.
The commonly used buffer structure of the moving truck hydraulic cylinder is composed of a piston boss and a moving truck hydraulic cylinder head groove. When the piston moves close to the moving truck hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
The wear of the hard chromium plating layer of the moving truck hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
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.
How to select the 2.5T bearing cylinder and hydraulic pump?
2,5 ton load is not heavy, you can use the rated pressure of 16 mpa gear pump, neither waste nor save cost, load/pressure = cylinder diameter, preset pressure of 8 mpa, 2500 (kg) /80 (bar) =31.25 square centimeters, in the open =63 mm, cylinder diameter can be selected 63 mm, stroke according to the situation, Hydraulic pump select gear pump, if there is a speed requirement, in order to calculate the displacement, the motor power also needs to determine the displacement of the pump to calculate.
