冷再生機(jī)對液壓油性能的要求很嚴(yán)格
來源：http://kqj188.com/ 日期：2022-05-11 發(fā)布人：
冷再生機(jī)作為一種施工設(shè)備，因此對液壓系統(tǒng)方面要求還是比較嚴(yán)格的，比如說液壓油在設(shè)備中起到的性能要很好，不然很容易就會(huì)影響到設(shè)備效率。那么冷再生機(jī)對液壓油性能的要求如何？
As a construction equipment, the cold regenerator has strict requirements on the hydraulic system. For example, the performance of hydraulic oil in the equipment should be very good, otherwise it will easily affect the efficiency of the equipment. So what are the requirements of the cold regenerator for the performance of hydraulic oil?
適當(dāng)?shù)恼扯?。粘度是油流?dòng)時(shí)分子間摩擦阻力的大小。粘度過大時(shí)，油液流動(dòng)阻力大，能量損失大，系統(tǒng)效率降低。此外，冷再生機(jī)主機(jī)空載損耗提升，溫度迅速升高，工作溫度高，主泵吸油端易出現(xiàn)“空穴”現(xiàn)象。如果粘度太小，就不能保證液壓元件良好的潤滑條件，會(huì)加劇元件的磨損，增加泄漏，降低液壓系統(tǒng)的效率。
Proper viscosity. Viscosity is the amount of frictional resistance between molecules when oil flows. When the viscosity is too large, the oil flow resistance is large, the energy loss is large, and the system efficiency is reduced. In addition, the no-load loss of the main engine of the cold regenerator increases, the temperature rises rapidly, the working temperature is high, and the "hole" phenomenon is easy to appear at the oil suction end of the main pump. If the viscosity is too small, good lubrication conditions of hydraulic components cannot be guaranteed, which will aggravate the wear of components, increase leakage and reduce the efficiency of hydraulic system.
良好的抗磨性和潤滑性。目的是減少冷蓄熱室的機(jī)械摩擦，保證在不同壓力、速度和溫度條件下有足夠的油膜強(qiáng)度?；瘜W(xué)反應(yīng)穩(wěn)定性高，不易被氧化變質(zhì)，具有良好抗氧化性和穩(wěn)定性的液壓油在長期使用后不易被氧化變質(zhì)，可以保證液壓油的正常循環(huán)。
Good wear resistance and lubricity. The purpose is to reduce the mechanical friction of cold regenerator and ensure sufficient oil film strength under different pressure, speed and temperature conditions. The hydraulic oil with good oxidation resistance and stability is not easy to be oxidized and deteriorated after long-term use, which can ensure the normal circulation of hydraulic oil.
破乳性好，不易起泡?？谷榛允侵赣团c水混合，攪拌后不成乳狀液，并能從中分離出水的能力。消泡是指油與空氣混合并攪拌而不形成乳狀液的能力和氣泡與油分離的能力。與水或空氣混合后，液壓油的體積模量降低，壓縮性增加，液壓元件運(yùn)動(dòng)緩慢，易產(chǎn)生沖擊和振動(dòng)。
It is not easy to break milk and has poor foaming property. Demulsibility refers to the ability of mixing oil and water, not forming emulsion after stirring, and separating water from it. Defoaming refers to the ability of oil and air to mix and stir without forming emulsion and the ability of bubbles to separate from oil. After mixing with water or air, the bulk modulus of hydraulic oil decreases, the compressibility increases, and the hydraulic components move slowly, which is easy to produce impact and vibration.
良好的粘溫特性。粘溫特性是指油品的粘度隨溫度變化的程度，通常用粘度指數(shù)來表示。粘度指數(shù)越大，液壓系統(tǒng)運(yùn)行過程中油液粘度隨溫度升高而下降的幅度就越小，這樣液壓系統(tǒng)的內(nèi)漏就不會(huì)太大。粘度指數(shù)一般不應(yīng)低于90。
Good viscosity temperature characteristics. Viscosity temperature characteristic refers to the degree that the viscosity of oil changes with temperature, which is usually expressed by viscosity index. The larger the viscosity index is, the smaller the decrease of oil viscosity with the increase of temperature during the operation of the hydraulic system, so that the internal leakage of the hydraulic system will not be too large. Generally, the viscosity index shall not be lower than 90.
良好的防銹性能。冷再生機(jī)租賃人員認(rèn)為液壓油覆蓋在冷再生機(jī)機(jī)械部件的表面，以防止它們被氧化和生銹。燃點(diǎn)和閃點(diǎn)應(yīng)符合環(huán)境溫度，揮發(fā)性要小，以保證液壓油的安全。
Good rust resistance. The leasing personnel of the cold regenerator believe that the hydraulic oil covers the surface of the mechanical parts of the cold regenerator to prevent them from being oxidized and rusted. The ignition point and flash point shall meet the ambient temperature and the volatility shall be small to ensure the safety of hydraulic oil.
