El Salvador hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder
(El Salvador tailplate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
tailplate hydraulic cylinder are widely used in El Salvador，because of no need for deceleration device，long service life，smooth movement.So our company has designed tailplate hydraulic cylinder for customers from El Salvador.
When purchasing the tailplate hydraulic cylinder, try to clarify the following parameters of the tailplate hydraulic cylinder: A. tailplate hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or tailplate hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right tailplate hydraulic cylinder type can be found accurately and quickly.
When the tailplate hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the tailplate hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.
tailplate 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 tailplate 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 ' tailplate 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 tailplate hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The tailplate hydraulic cylinder mainly outputs linear motion and force. The tailplate 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 tailplate hydraulic cylinder, plunger tailplate hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger tailplate hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the tailplate hydraulic cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
Need to buy a hydraulic cylinder, now only know that the pressure needs to be between 20t and 50t. Two-way travel, how to determine the type of cylinder?
Important parameters of the cylinder: cylinder diameter, stroke, use pressure. First, the system pressure must be determined according to the precision of the operation of the application equipment, and the cylinder diameter can be determined by the force and system pressure. Then, according to how the equipment and the cylinder are installed and connected, determine the installation method of the cylinder and then determine the specific installation size, the size of the oil port, whether the buffer is needed and other details.
