It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Xinjiang Hydraulic cylinder 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 Xinjiang Hydraulic cylinder Manufacturer Flow rate and flow direction. For example: pressure control valve, flow control valve.
The two lips of the seal have two contact circumferential surfaces. Whether the force on the inner and outer circumferences is evenly distributed means that the force on the two circumferences cannot be zero. If the force on a certain point is zero, the shaft seal has inner and outer lips, Xinjiang Hydraulic cylinder The outer lip is installed in the groove to contact the outer wall, and the inner lip is in contact with the piston rod surface. Both lips have an interference amount, which is equal to the generation of two contact circumferential surfaces, that is, the generation of two circumferential rebound forces. How to determine the magnitude of the circumferential force? Both the inner and outer lips of the seal have two chamfers. Since the interference of the same inner and outer lips is certain, Xinjiang Hydraulic cylinder Manufacturer The angle of the chamfer determines the size of the circumferential area of the inner and outer contact of the two lips.
Because the hydraulic cylinder has to bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is an important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system, Xinjiang Hydraulic cylinder It is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder should be careful. First, rust prevention. Because the piston part of the hydraulic cylinder will extend the cylinder in the working state, Xinjiang Hydraulic cylinder Manufacturer Naturally, it will be corroded by oxide and acid gas, which requires us to coat it with proper grease for protection.
There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that only drain the oil in the hydraulic cylinder and fill it with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve, Xinjiang Hydraulic cylinder When the equipment is used, the mixing of new and old oil will speed up the deterioration of new oil. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, Xinjiang Hydraulic cylinder Manufacturer After cleaning the hydraulic cylinder, add new hydraulic oil, remove the circuit header, start the engine and run at low speed to make the oil pump work.
Fluid cleanliness. The cleanliness of the system oil will have a very important impact on the hydraulic cylinder. Hydraulic shock and vibration hydraulic cylinders will be affected by the performance of components, pipeline and medium characteristics, etc., which will be accompanied by hydraulic shock and vibration. Generally speaking, if the oil temperature is too high or too low, Xinjiang Hydraulic cylinder Manufacturer Will have a great impact on the working efficiency of the hydraulic cylinder. If the oil temperature of the hydraulic cylinder is too high or too low, the physical and chemical properties of the medium will change, Xinjiang Hydraulic cylinder As a result, the viscosity of the working medium decreases or the possibility of leakage increases.
