The hydraulic oil in the oil electric hybrid CNC bending machine is used in the hydraulic transmission system as the working medium, which plays the role of energy transmission, conversion and control. At the same time, it also plays the role of lubrication, anti-corrosion, rust prevention and cooling of various components in the hydraulic system. The seals in the hydraulic system play a role in preventing fluid leakage from the joint surface, maintaining pressure, maintaining energy transmission or conversion.,longest yard basketball gif

A: Hazards of high oil temperature in the system

tennis kinder talente,1. The viscosity of hydraulic oil of NC bending machine decreases

The viscosity of hydraulic oil changes with the change of temperature. If the temperature is too high, the viscosity of hydraulic oil will decrease, which is easy to leak and reduce the volumetric efficiency. At the same time, the lubrication performance becomes worse, resulting in increased wear and even sintering.,soccer ball size meaning

unc basketball violations,2. Parts of the hydraulic system expand due to overheating

Because the linear expansion coefficient, heating and heat dissipation conditions of each component of the system are different, and the thermal expansion of each component is not exactly the same, the resulting deformation is also different, which is likely to destroy the original normal fit clearance of the relatively moving parts, increase the friction resistance and make the valve core easy to get stuck. At the same time, high temperature thins the lubricating oil film and increases mechanical wear, resulting in the failure or even scrapping of the precision mating surface in the component due to premature wear.,dundalk fc

teen patti pc game,3. The oxidation stability and thermal stability of the oil are damaged

Oxidation stability: refers to the ability of a liquid to resist chemical reactions with Oxygenates (especially air).,pokerstars mobile app android download

Thermal stability: it is the ability of liquid to resist chemical reaction at high temperature.,outdoor volleyball courts pittsburgh

tennis australia v spain,During the use of the oil, due to the influence of heat, oxygen and metal materials, the oil will oxidize and deteriorate. When the temperature and pressure increase, the oxidation rate will accelerate, and the substances generated by oxidation will enhance their corrosivity to metals.

4. Accelerate the aging and deterioration of seals, shorten the service life and lose the sealing performance, resulting in serious leakage of the system.,yorkshire junior tennis rankings

5. It is easy to produce impurities, the oil temperature is too high, it is easy to vaporize, make the water evaporate, and the components are easy to produce cavitation corrosion. The oil oxidizes to form colloidal deposits, which block the filter element and the resistance hole in the hydraulic valve, so that the system does not work normally.,cricut joy app deutsch

B、 Causes of high oil temperature in CNC Press brakes

handball league champion,1. The type and viscosity grade of oil do not meet the requirements.

Each variety of hydraulic oil is suitable for working in hydraulic systems in different environments. For example, L-HM anti-wear hydraulic oil shall be used for the hydraulic system running for a long time.,basketball bag big

gmod peer to peer,2. The hydraulic oil is seriously polluted

Due to the internal and external objective conditions, in areas with poor environment (dusty and humid areas), the longer the working time of the hydraulic system, the easier it is to mix impurities and dirt into the oil, which will damage the accuracy of the mating surface of hydraulic components, increase leakage, and shorten the service life of components in serious cases. Especially when the dirt passes through the oil filter, it will be adsorbed on the filter element in the oil filter, resulting in an increase in oil absorption resistance and energy consumption, resulting in an increase in oil temperature.,brisbane roar fc

3. The liquid level in the oil tank is too low,cricket score app for pc

If there is too little oil in the oil tank, the hydraulic system will not have enough flow to take away the heat generated in the system, resulting in the rise of oil temperature.,tennis court hamilton

online cricket betting games,4. Air is mixed into the system

the national lottery,Under low pressure, the air forms many small bubbles in the oil. When it moves to the high-pressure area, these small bubbles will be instantly broken by the high-pressure oil. The compressed and broken bubbles will release a lot of heat and cause the oil temperature to rise.

5. The oil filter is blocked,tennis australia v spain

C: Preventive measures for CNC handball referee equipment

live casino online free,1. The brand of oil shall be selected reasonably, and special hydraulic oil shall be selected for some equipment with special requirements. For long-time high load operation and long oil change time, anti-wear hydraulic oil with good performance shall be selected. At present, L-HM 46 hydraulic oil is mostly used in the hydraulic system of the unit.

soccer aid dermot kennedy,2. Replace the hydraulic oil periodically.

nbc sports soccer youtube,3. During the initial operation of the equipment, oil shall be injected into the oil filling hole of the hydraulic pump, and the coupling between the hydraulic pump and the motor shall be manually turned for several turns to make the pump full of oil, so as to avoid the heat generated in the high-speed rotation state due to the suction of air or lack of lubrication, which will increase the oil temperature and even wear the components.

4. Select appropriate cooler, which is related to power.,fish game gambling

youth tennis court shoes,5. The filter element of CNC bending machine shall be replaced regularly to ensure that the oil is clean and the oil circuit is unblocked.

online maharashtra lottery,Hydraulic technology is developing towards high pressure, high frequency, rapid response and guidance. The requirements for media are becoming higher and higher, and troubleshooting is more difficult. However, 80% of the faults of hydraulic system are directly related to hydraulic media. Therefore, the selection of hydraulic medium and daily maintenance are very important. Only on this basis can the hydraulic system of NC bending machine run more stably and have a longer service life.
