Hydraulic oil cylinder is used in many industries. Once it fails, it will have a far-reaching impact and hinder the progress of all work. In fact, many customers said that the hydraulic cylinder could not operate, Zhanjiang Hydraulic station In order to solve this problem in time, we should first find out what causes the problem. Generally speaking, the problem that the hydraulic cylinder cannot act often occurs on the newly installed hydraulic cylinder, Zhanjiang Hydraulic station Manufacturer Generally, it is necessary to start from external reasons, such as whether the mechanism pulled by the hydraulic cylinder has excessive resistance, whether it is stuck, and whether it is against other parts; Whether the pressure at the oil inlet of the hydraulic cylinder is within the specified range.
As the structure and size of various hydraulic cylinders are different, the disassembly sequence is slightly different. Generally, drain the oil in the two chambers of the oil cylinder, remove the cylinder head, and finally remove the piston and piston rod. Zhanjiang Hydraulic station When disassembling the cylinder head of the hydraulic cylinder, special tools shall be used for the key or snap ring of the internal key type connection, and flat shovel is prohibited; Flange end caps must be pushed out with screws, and hammering or hard prying is not allowed. When it is difficult to draw out the piston and piston rod, do not force them out, Zhanjiang Hydraulic station Manufacturer The reason shall be found out before disassembly. Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being polluted by the surrounding dust and impurities.
1. 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 in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Zhanjiang Hydraulic station Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Zhanjiang Hydraulic station Manufacturer Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.
It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Zhanjiang Hydraulic station The movement is transmitted through the change of sealing volume, and the power is transmitted through the pressure inside the oil. 1. Power part - converts mechanical energy of prime mover into pressure energy (hydraulic energy) of oil. For example: hydraulic pump. 2. Executive part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy driving the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control part - used to control and adjust the oil pressure Zhanjiang Hydraulic station Manufacturer Flow rate and flow direction. For example: pressure control valve, flow control valve.
The failure of the hydraulic cylinder due to improper design and manufacture is because the oil pressure cannot act on the effective working area of the piston when the piston travels to the end point and returns, or the effective working area is too small when starting, which causes problems. When the transverse load of the hydraulic cylinder is too large, the force is not strong or the cylinder is bitten, the same consequences will occur. Zhanjiang Hydraulic station Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Zhanjiang Hydraulic station Manufacturer And ensure that the load borne by the hydraulic cylinder passes through the cylinder axis as far as possible without eccentricity, so that the problem can be solved.
The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, Zhanjiang Hydraulic station Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, Zhanjiang Hydraulic station Manufacturer There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.
