(Azerbaijan hydraulic telescopic cylinder,produced by Hebei Hengyu company）
hydraulic telescopic cylinder are widely used in Azerbaijan，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed hydraulic telescopic cylinder for customers from Azerbaijan.
How the cavitation of the hydraulic telescopic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the hydraulic telescopic cylinder, resulting in corrosive damage to the parts.
The hydraulic telescopic cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
The hydraulic telescopic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the hydraulic telescopic cylinder should pay attention to: the operation should be as far away from the hydraulic telescopic cylinder as possible, to avoid falling objects, knocking, rubbing the hydraulic telescopic cylinder coating. When cleaning the hydraulic telescopic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the hydraulic telescopic cylinder when the oil temperature exceeds 70 ° C.
hydraulic telescopic cylinder and hydraulic station selection: Select the type and structure of the hydraulic telescopic cylinder according to the operation requirements of the main engine. According to the external load force borne by the hydraulic telescopic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the hydraulic telescopic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the hydraulic telescopic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the hydraulic telescopic cylinder, the diameter of the piston and the piston rod.
How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
How does the cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, the executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, the control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, the auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
