How to select hydraulic oil for single-layer hot press?

What type of hydraulic oil should be selected for single-layer hot press, etc.? Here is how to select hydraulic oil. Leather hot press is also known as bonding machine. According to the different media of hot pressing, it can be divided into tin welding, ACF (anisotropic conductive tape), ACP (anisotropic conductive adhesive), TBF (hot melt adhesive film). It is applicable to the connection of FPC (flexible circuit board), HSC (zebra paper), TAB, LCD and PCB. High-temperature hot press is a kind of electrical and mechanical connection device between the parts and the solder after heating the two parts coated with solder flux in advance to a temperature sufficient to melt and flow the solder. According to the pulse heating principle of the hot press, due to the special design of the welding head surface, the resistance of the welding surface is very small, and the current will pass through the section with the minimum resistance. By constantly changing the voltage, adjusting the current level, and rapidly heating the welding head.
Single-layer hot press relies on hydraulic oil to transfer kinetic energy, and the correct selection of hydraulic oil is directly related to the performance of the hot press.
There are many brands of hydraulic oil, and you should not buy cheap renewable oil, which will affect the performance and use of the hot press.
When selecting hydraulic oil, different types of hydraulic oil should be selected according to the system pressure, working environment and temperature of the hot pressing machine. What is the choice of hydraulic oil?
Hydraulic oil is divided into general hydraulic oil, anti-wear hydraulic oil, hydraulic guide oil and low-temperature hydraulic oil according to the additives added in the base oil. If the system pressure of the hot press is 7mpa, HL ordinary hydraulic oil can be used. If the piston pump or vane pump is used as the power source of the hot press, and the pressure of the system is medium and high pressure, then the hydraulic oil selected in the system should be HM anti-wear hydraulic oil to ensure the normal operation of the fine components in the nutrition system. If the ambient temperature is lower than zero, HS low temperature hydraulic oil should be selected. Compared with HS low-temperature hydraulic oil, high-pressure low-temperature hydraulic oil is suitable for lower environment.
Even if it is the same hydraulic oil, the steel and wood door embossing machine should choose the hydraulic oil with different viscosity under different ambient temperatures. Dynamic viscosity is an index reflecting the fluidity of hydraulic oil. Dynamic viscosity: refers to the force required to produce unit flow with unit distance and unit area of liquid layer. Kinematic viscosity: the ratio of dynamic viscosity to density. The customary unit is centistokes. The lower the dynamic viscosity, the better the low temperature fluidity.
The suitable working environment temperature of hydraulic oil is 20C60C. The hot press equipment developed and produced by Tengzhou intermodal needs to be equipped with water-cooled cooler device in the oil tank. When the hot press works, the cooling device can be automatically opened through a temperature measuring device to achieve the function of automatic management and control of oil temperature.
Solid particles are unavoidable in the hydraulic oil. It is stipulated that the cleanliness of the hydraulic oil of the medium and high pressure hydraulic system shall not be lower than NAS 9.
