The hydraulic oil selection and use standard

In the production process of the plastic blow molding machine, it is of great significance to select the correct and reasonable hydraulic oil, which can further optimize the efficiency of each process link of the blow molding machine. The question is: How to choose the hydraulic oil for the plastic blow molding machine? What are the standards or criteria for selecting hydraulic oil for blow molding machine?

Viscosity of hydraulic oil

For the production process of the blow molding machine, the proper viscosity of the hydraulic oil should be selected in combination with the actual operating conditions of the blow molding machine, including the temperature, working pressure, movement speed, etc. of the production environment.

If the production environment temperature of the equipment is high, the working pressure is high, and the movement speed is low, in order to reduce the leakage of hydraulic oil, the hydraulic oil with high viscosity should be selected for the blow molding machine; If the production environment temperature is low, the working pressure is low, and the movement speed is high, the equipment hydraulic oil with lower viscosity should be selected.

The viscosity of hydraulic oil will have different effects on the lubrication of moving parts of the blow molding machine, the leakage between gaps, the pressure consumed when the hydraulic oil flows, the heating and heating of the equipment system and other process links, and will also have different effects on the overall operation of the blow molding machine. This is why the equipment hydraulic oil with different viscosity should be selected according to the actual production conditions of the blow molding machine.

Select according to different types of machinery

The special production process of blow molding machine requires the use of hydraulic oil with anti-wear properties. Although the price of anti-wear hydraulic oil is higher, in the long run, it is very necessary to protect the equipment, which can better play the role of hydraulic oil.

If it is an ordinary machine with simple production process, ordinary hydraulic oil can meet the production needs of the equipment; For example, blow molding machines are high speed and high pressure construction machinery. The loss of equipment during production is large, and the lubrication requirements for hydraulic oil are high. Therefore, anti-wear hydraulic oil should be selected for the construction machinery of blow molding machines. If the equipment uses a hydraulic servo system, the hydraulic oil should also have the characteristics of pure oil and low compressibility.

Select the hydraulic oil according to the hydraulic pump of the blow molding machine

Select the type of hydraulic oil according to the type of hydraulic pump used by the blow molding machine.

In the hydraulic device of the blow molding machine, the hydraulic pump is an indispensable component. At the same time, its operating environment is also in the entire hydraulic system, which is harsh. The feedback to the hydraulic oil is also very timely and sensitive. If the quality and performance of the hydraulic oil do not meet the requirements of the equipment production, the hydraulic pump will quickly show adverse reactions in the process of operation.

When the blow molding machine equipment leaves the factory, the manufacturer will attach a blow molding machine instruction manual to the equipment. As for the selection of hydraulic oil for the blow molding machine equipment, it will indicate the brand and quantity of hydraulic oil that the equipment needs to use. We will use the hydraulic oil according to the type specified in the instruction, and there will be no problem.

How to select hydraulic oil for blow molding machine? It should be selected according to the actual operating conditions such as the production process and production environment of the blow molding machine, so as to better play the role of hydraulic oil. The hydraulic oil with good quality and performance should also be selected as much as possible. Although the cost is high, the good hydraulic oil has a long service life and stable performance. While playing its role, it has little damage to the parts of the blow molding machine. In the long run, the performance price ratio is still high.
