How to choose hydraulic oil for non-ferrous metal hydraulic press we take a look at below. 1. The viscosity, density and temperature should be within the operating temperature range, and the viscosity of the oil should change relatively little with temperature, and it has good lubricating properties. Oil is not only a medium for energy transfer, but also a lubricant between relatively moving parts.

  1. The viscosity, density and temperature should be within the operating temperature range, and the viscosity of the oil should change relatively little with temperature, and it has good lubricating properties. Oil is not only a medium for energy transfer, but also a lubricant between relatively moving parts.

  2. The hydraulic oil should form a high-strength oil film on the sliding surface of the parts to form liquid lubrication and avoid dry friction.

  3. The quality of the hydraulic oil should be pure and free of any impurities. If they contain acids and alkalis, they can corrode parts and seals. If it contains mechanical impurities, it is easy to block the oil circuit. If it contains volatile substances, long-term use will thicken the oil and air bubbles will easily occur in the oil.

  4. Hydraulic oil is not easy to oxidize. In use, due to the increase in temperature, colloids and asphaltenes may be produced, which will deteriorate the oil quality. At the same time, these substances are easy to block the oil circuit, adhere to the surface of the relative movement of the object, and affect the work.

  Hydraulic oil should be stored in a fireproof place, and its ignition point should be higher. In cold climates, its freezing point should be lower. If water is added to the oil, the oil will be emulsified, the lubrication performance will be reduced, the acid value will be increased, and the service life will be shortened.

  6. The hydraulic oil will produce foam during use, which will cause the system to cut off oil or cavitation, and affect the normal operation of the system. Therefore, the hydraulic oil should have good anti-emulsification and anti-foaming properties. Good compatibility, I .e. no detrimental effects such as dissolution on seals, hoses and sheaths. Hydraulic oil is harmless to the human body and has low cost.

InNon-ferrous metal hydraulic pressIn the process of machining the workpiece, the parameters should be adjustedNon-ferrous metal hydraulic pressThe ideal state, otherwise it will reduce the surface quality and machining accuracy of the workpiece being processed, which in turn will leadNon-ferrous metal hydraulic pressThe wire cutting surface is rough. What is the cause of this phenomenon?Non-ferrous metal hydraulic pressManufacturers below to introduce.

  1. The workpiece data is different, such as melting point, gasification point,Non-ferrous metal hydraulic pressThermal conductivity, etc. Therefore, even if the workpiece obtained by the hydraulic press is processed by the same method, its surface quality is different, and the workpiece data should be selected according to the actual surface quality.

2. The residual stress in the workpiece has a great influence on the processing. When the material after heat treatment is processed, due to large-scale metal removal and bulk processing, the relative balance of residual stress in the material will be destroyed, which will affect the machining accuracy and surface quality of the parts. In order to cope with these situations, materials with good castability, good hardenability and small heat treatment deformation should be selected.
