There are many brands of shears, and the fish are mixed, so everyone must be careful when purchasing shears. In order to be able to choose a reliable shearing machine, you must master the basic purchasing skills. So, what are the purchasing skills of the shearing machine? Next, world press machine will briefly analyze several shearing machine purchasing skills for you.
Different brands of hydraulic shearing machines have different selection of hydraulic oil? Usually, for the selection of hydraulic oil, many businesses choose brands, thinking that the more expensive the brand is, the better, but in fact, many hydraulic shearing machine companies are Has its own cooperative hydraulic oil brand. But for the choice of hydraulic oil, we recommend that you choose according to your own shearing machine needs and performance characteristics, and do not listen too much to others or trust the brand.
The most important thing is to take into account the composition of the hydraulic oil and the system pressure of the shearing machine, configuration and other operating environment conditions, etc., during the operation. The hydraulic oil temperature changes with the load and ambient temperature, and the viscosity index of the hydraulic shearing oil to be too fine is usually not lower than 90. so that the most suitable one can be selected.
Thereby, the viscosity-temperature property of hydraulic oil can be restrained. The viscosity-temperature property here refers to the degree to which the viscosity of the oil changes with temperature, which is usually reflected by the viscosity index. And in the operation of the hydraulic system of the shearing machine, the lower the viscosity of the oil decreases with the increase of temperature, the working conditions of the hydraulic system of the shearing machine are usually worse.
Viscosity is one of the most important and important indicators of hydraulic oil performance, because it is related to whether the hydraulic system can work normally and the service life of the hydraulic press. Therefore, we should take it seriously when choosing, and we cannot choose the wrong one, otherwise it will bring bad results. In the hydraulic system of the hydraulic press, the quality of hydraulic oil is very urgent.
So that the internal leakage of the hydraulic system will not be too large. Whether it is suitable or not will affect the stability of the hydraulic system movement, the reliability and sensitivity of the hydraulic system work. The larger the viscosity index of the hydraulic press, the number of accumulators driven by the pump-accumulator can be one or a group. If there is a surplus of working fluid, the accumulator is used to store it, and if it is not enough, continue to add.
But in fact, whether it is a hydraulic press or a hydraulic shearing machine, as long as it is a machine tool with its own hydraulic system, the demand for hydraulic oil is indispensable. Here, it mainly depends on the performance characteristics of each mechanical machine tool.
