Basic introduction of hydraulic cylinder for electric forklift

Electric forklift hydraulic cylinder: The cavitation of the oil cylinder has a significant impact. To avoid it, it is necessary to use hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the oil has poor foam resistance, it is easy to produce foam, which will lead to cavitation. Secondly, if the frequency of changes in oil pressure is too fast or too high, it will directly cause the formation of bubbles and accelerate the rate of bubble rupture. Experimental results have shown that areas with high frequency of pressure changes will experience accelerated cavitation. At the inlet and return ports of hydraulic cylinders, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than other parts. In addition, overheating of the oil also increases the probability of cavitation. The definition of minimum stable speed: refers to the minimum movement speed at which the hydraulic cylinder does not crawl when operating at full load. There is no unified index for it, and hydraulic cylinders that undertake different tasks have different requirements for the minimum stable speed. What kind of process should be used to produce high-quality oil cylinder products for the cylinder barrel? As the main component of hydraulic cylinders, mining single support columns, hydraulic supports, cannon barrels and other products, the quality of the cylinder barrel's processing directly affects the life and reliability of the entire product. The processing requirements for the cylinder barrel are high, with an inner surface roughness requirement of Ra0.4-0.8 μ m, and strict requirements for coaxiality and wear resistance. The basic characteristic of cylinder barrel is deep hole machining, which has always troubled machining personnel. Our company's oil cylinder products mainly use rolling processing. Due to the residual compressive stress left on the surface layer, it helps to close small cracks on the surface and hinders the expansion of erosion. Thereby improving the surface corrosion resistance and delaying the generation or expansion of fatigue cracks, thus enhancing the fatigue strength of the cylinder. Through rolling forming, a cylinder is formed on the rolling surface. After maintenance, the hydraulic system should run smoothly for a certain period of time to ensure that the hydraulic oil in the hydraulic system is fully circulated; If necessary, the hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Overflow hydraulic oil to achieve the effect of exhausting a single hydraulic cylinder. Selection of hydraulic oil for hydraulic cylinders: It is recommended to use working oil with a viscosity of 10-110cSt (1.8-15E) and ISO VG46 hydraulic oil for hydraulic cylinders. The normal working oil temperature is between 10-70 ℃, and the ambient temperature is within the range of -20-80 ℃. When the ambient temperature and operating temperature are low, hydraulic oil with lower viscosity can be selected.

Maintenance and related issues of hydraulic cylinders for electric forklifts

• (For those who have used the mechanical design manual, please enter) May I ask how the hydraulic cylinder is selected in the mechanical design manual
  Firstly, you need to meet your job requirements, and secondly, you need to ensure that the structural space of the oil cylinder and accessories meets the requirements. Consider other parameters of the oil cylinder.
• How to calculate the inner diameter of a hydraulic cylinder
  These two parameters require the following information to determine: 1. Pump displacement, speed (to obtain the actual output flow rate of the pump), 2. Requirements for three items and time (how many seconds are needed for lifting and lowering), and then view the adjacent hydraulic cylinder series based on the results. Choose the appropriate hydraulic cylinder.
• What type of oil cylinder is generally used for molds, and what are the general types
  Choose the size of the oil cylinder according to the stroke, and the price is generally mid-range, but it depends on how many times the lifespan is,
• How to determine the model of the hydraulic cylinder for the elevator? I am eager to know.
  I have dealt with the hydraulic cylinder of Hengyu Elevator before. Let me answer your question. I can tell from the number 10 that you are using a guide rail elevator hydraulic cylinder. Don't ask why, industry experience. Multiplying by 3.14 is to determine the inner diameter of the hydraulic cylinder of the elevator, multiplying by 10 is to calculate the thrust of the elevator hydraulic cylinder (because the pressure of the guide rail elevator hydraulic station is about 10Mpa), and multiplying by 2 represents the thrust of the two hydraulic cylinders. For example, if your guide rail elevator rises 10 meters, has a load capacity of 5 tons, and a table size of 3 meters * 5 meters, then the hydraulic cylinder model of your elevator is 100/80-5100100, which is the inner diameter of the cylinder, 80 is the diameter of the piston rod, and 5100 is the lifting oil
