(Costa Rica self-locking hydraulic cylinder,produced by Hebei Hengyu company）

self-locking hydraulic cylinder are widely used in Costa Rica，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed self-locking hydraulic cylinder for customers from Costa Rica.

Introduction to self-locking hydraulic cylinder:

The self-locking hydraulic cylinder is mainly composed of body, piston, piston rod, self-locking hydraulic cylinder head, self-locking hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the self-locking hydraulic cylinder into two chambers, and moves reciprocally in the self-locking hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the self-locking hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the self-locking hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the self-locking hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the self-locking hydraulic cylinder bottom and the self-locking hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the self-locking hydraulic cylinder The working medium of the self-locking hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; self-locking hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the self-locking hydraulic cylinder: The buffer structure of the self-locking hydraulic cylinder is to prevent the piston from colliding with the self-locking hydraulic cylinder head at the end of the stroke.

The body of the self-locking hydraulic cylinder on the processing process requirements: the body of the self-locking hydraulic cylinder is an important and essential part of the self-locking hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the self-locking hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

self-locking hydraulic cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a self-locking hydraulic cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' self-locking hydraulic cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the self-locking hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The self-locking hydraulic cylinder mainly outputs linear motion and force. The self-locking hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston self-locking hydraulic cylinder, plunger self-locking hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger self-locking hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

The meaning of the self-locking hydraulic cylinder model marked by the self-locking hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the self-locking hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the self-locking hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about self-locking hydraulic cylinder:

Cylinder la-50-70st What does that mean?
Full model should be CX-LA-50-70ST, thin block cylinder, radial mounting, bore 50, stroke 70.

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
