Hydraulic cylinder operation is not without the role of hydraulic oil, bending machine cylinder saao 90R180 hydraulic pump accessories in the hydraulic oil play a role in the meantime, there will be some pressure. These pressures are basically the hydraulic oil under load with a resistance force, so we need to understand the source of the hydraulic system load, in order to explain the process of hydraulic oil pressure.

When the cylinder is in operation, some external load will be applied to the hydraulic system through the piston in the equipment, in order to balance this force, the hydraulic oil must produce some corresponding pressure saao 90R130 hydraulic pump accessories. Secondly, the hydraulic oil itself will have weight, will also change to the resistance of the hydraulic cylinder, so that the hydraulic oil also has the necessity of pressure.In addition, the oil has a certain viscosity, in the flow process, Hitachi series accessories and containers will produce a certain amount of friction resistance. In order to overcome the adverse effects of friction resistance, pressure is still needed to balance. So that's how you get the pressure in the hydraulic cylinder in the hydraulic oil.
