tailplate hydraulic cylinder are widely used in Estonia，because of no need for deceleration device，long service life，smooth movement.So our company has designed tailplate hydraulic cylinder for customers from Estonia.

Introduction to tailplate hydraulic cylinder:

The commonly used buffer structure of the tailplate hydraulic cylinder is composed of a piston boss and a tailplate hydraulic cylinder head groove. When the piston moves close to the tailplate 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.

At the rated pressure, the thrust of the tailplate hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the tailplate hydraulic cylinder is related to the diameter of the tailplate hydraulic cylinder, but not to the stroke of the tailplate hydraulic cylinder. Moreover, the larger the tailplate hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the tailplate hydraulic cylinder.

The assembly work of the tailplate hydraulic cylinder has a great impact on the quality of the tailplate hydraulic 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 cavitation of the tailplate hydraulic cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the tailplate hydraulic cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

Answers to some questions about tailplate hydraulic cylinder:

What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.

Does the excavator use a hydraulic cylinder?
First, construction machinery is generally a hydraulic cylinder. Second, hydraulic transmission equipment is usually composed of four components, power, execution, control and auxiliary. And the hydraulic cylinder as a linear reciprocating motion or less than 360. Reciprocating motion of the hydraulic mechanism, simple structure, reliable work, is also widely used in the hydraulic system of the main actuator, it is the prime mover in the form of mechanical energy to drive the hydraulic pump produced by the liquid pressure energy, and then can be directly driven load for reciprocating movement or less than 360.
