press hydraulic cylinder are widely used in Colombia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed press hydraulic cylinder for customers from Colombia.

Introduction to press hydraulic cylinder:

press 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 press 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 ' press 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 press hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The press hydraulic cylinder mainly outputs linear motion and force. The press 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 press hydraulic cylinder, plunger press hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger press hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

Disassembly press hydraulic cylinder: When disassembly press hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the press hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the press hydraulic cylinder.

When the press hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the press hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil press hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical press hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the press hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

press hydraulic cylinder use should try to avoid sealing belt into the press 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 press 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 press 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.

Answers to some questions about press 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.

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
