The importance of hydraulic system temperature of metal baler

What kind of danger will the hydraulic system of the metal baler bring if the temperature is too high? The continuous operation of hydraulic equipment will generate high temperature. The working temperature of the hydraulic system of the waste paper hydraulic baler, straw baler, and plastic hydraulic baler is usually limited to 80°C or less.

According to the test, the temperature of the hydraulic system is generally within the range of 60-80°, and the temperature should not exceed 100°. The waste paper baler has the characteristics of good rigidity, toughness and stability, beautiful appearance, convenient operation and maintenance, and low investment cost of equipment basic engineering. It is widely used in all kinds of waste paper factories, waste recycling companies and other units and enterprises. It is suitable for the packaging and recycling of waste paper, plastic straw, etc. It is a good equipment to improve labor efficiency, reduce labor intensity, save manpower, and reduce transportation costs. Under normal oil temperature, hydraulic oil performs well.

Excessive oil temperature of the hydraulic system may cause:

Thermal deformation of waste paper packaging mechanical parts causes the thermal expansion coefficients of different moving parts in the hydraulic components to get stuck due to their small matching gaps, causing action failure, affecting the transmission accuracy of the hydraulic system, and deteriorating the quality of parts.

Reduce lubricating oil viscosity and increase leakage. The volumetric efficiency of the pump and the efficiency of the entire system will be greatly reduced. As the viscosity of the oil decreases, the oil film of the sliding valve and other moving parts becomes thinner and thinner, and the friction resistance increases, resulting in (producing, contributing to) wear (a basic type of component failure) intensified.

The waste paper presses the rubber seal to deform, accelerate the aging failure, reduce the sealing performance and service life, and cause leakage.

Accelerate oil oxidation and deterioration, precipitate asphalt materials, and reduce the service life of hydraulic oil. The sediment blocked the orifice and the gap valve, making the pressure valve stuck and dead, and the metal pipe was bent or even broken.

Hydraulic baler, also known as strapping machine, strapping machine or strapping machine, uses strapping straps to bind products or packages, then tighten them and combine the two ends with a heating iron. The function of the baler is to reinforce the packaged goods, so that the goods will not be scattered due to inadequate binding during transportation and storage, and should be tied neatly and beautifully. The air separation pressure of the oil is greatly reduced, so that the air dissolved in the oil escapes, resulting in cavitation, which causes the performance of the hydraulic system to decrease.
