Precautions for the use of construction machinery cylinders
In general, when the construction machinery is working, the hydraulic system of the engineering hydraulic cylinder generates a large amount of heat due to various pressure losses, which causes the temperature of the hydraulic oil in the system to rise, and the hydraulic oil is susceptible to oxidation when the system temperature is too high. Due to the formation of organic acids after oxidation, the organic acids will corrode metal components, and at the same time, it will also generate gel-like precipitates that are insoluble in oil, which will eventually increase the viscosity of the hydraulic oil and deteriorate the wear resistance.
Engineering machinery oil cylinders are widely used in steel, light industry, military, environmental protection, hydropower and other fields due to their good characteristics. Its principle is that the reciprocating motion of the hydraulic cylinder drives the gear through the rack, and is converted into the forward and reverse swing rotation of the gear shaft, while the thrust of the reciprocating cylinder is converted into the output torque of the gear shaft. However, it should be noted that because the swing angle of the gear shaft is proportional to the length of the rack, the swing angle of the gear shaft can be arbitrarily selected and can be greater than 360 degrees.
Users who use engineering hydraulic cylinders know that it is a hydraulic component that provides hydraulic fluid with pressurized fluid, and it is also a type of pump. The working principle of a manual pump is to convert the mechanical energy of a power machine (such as an electric motor and an internal combustion engine) into pressure energy of a liquid. The output flow that can be adjusted according to needs is called a variable pump, and the flow that can not be adjusted is called a fixed displacement pump. Among them, the oil pipe of the engineering hydraulic cylinder plays a very important role in the entire working process.
