construction machinery hydraulic cylinder are widely used in Costa Rica，because of long service life，smooth movement，high work efficiency.So our company has designed construction machinery hydraulic cylinder for customers from Costa Rica.

Introduction to construction machinery hydraulic cylinder:

In the process of using the construction machinery hydraulic cylinder, sometimes such a problem will occur, the construction machinery hydraulic cylinder can not act immediately after the instruction of the construction machinery hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil construction machinery hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

When the construction machinery hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the construction machinery hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The commonly used buffer structure of the construction machinery hydraulic cylinder is composed of a piston boss and a construction machinery hydraulic cylinder head groove. When the piston moves close to the construction machinery 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 advantages and disadvantages of the construction machinery hydraulic cylinder: the surface of the construction machinery hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the construction machinery hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

Answers to some questions about construction machinery hydraulic cylinder:

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.
