In the pipeline press opening project, the oil medium used in the press opening machine should be distinguished clearly. If you add wrong, it will not only cause the wear of the equipment, but also reduce the efficiency of the press opening machine, and even cause production accidents. The following is a brief introduction to the difference between hydraulic oil and hydraulic transmission oil:
First, the liquid as the working medium to transfer energy and control the transmission mode, known as liquid transmission. Liquid transmission is divided into hydraulic transmission and hydraulic transmission.
Hydraulic transmission is the use of liquid pressure can transfer power and motion transmission, also known as positive displacement hydraulic transmission. For example, the working medium of the press opening machine is hydraulic transmission.
Hydraulic transmission is the transmission of power by means of liquid kinetic energy. In fact, it is a kind of energy conversion device with liquid as the working medium. There are two forms of coupler and torque converter. It mainly refers to the lubricating oil used in the transmission box used in the press opening machine.
The oil used as the transmission medium of hydraulic system is called hydraulic oil, we call it hydraulic transmission oil, also known as hydraulic fluid. Oil used as a hydraulic transmission medium. We call it hydraulic transmission oil, also known as automatic shift oil, direction oil, booster oil, etc., in the professional with pressure opening, we call it transmission oil.
What performance requirements should hydraulic fluids have?
Hydraulic oil is an indispensable transmission medium of hydraulic transmission. In order to adapt to transmission requirements, hydraulic oil should have the following properties:
1. Good viscosity-temperature performance. In the use of temperature range, the viscosity of the oil with the temperature change should be relatively small, that is, the viscosity index should be high.
2, with good lubrication. Hydraulic oil (liquid) is not only a medium for transferring energy, but also a lubricant for mechanical movement. It has good lubricity to ensure the normal work of machinery.
3, the quality is pure, does not contain mechanical impurities, non-corrosive.
4, not easy to oxidize. Reduce and avoid the formation of oxides when the temperature rises, accelerate the deterioration of oil products and clog the oil circuit.
5. When working at high temperature, the flash point should be high; When working at low temperature, low temperature fluidity is better.
6, good water separation, high gas extraction, to avoid emulsification and foam.
7, with good compatibility, no dissolving and other harmful effects on seals/hoses, coatings, etc.
