斷橋鋁鋁門窗設備中的數控四頭組角機、雙頭組角機、單頭組角機都要使用液壓油，因此，液壓油質量的好壞，對門窗設備質量會有不同程度的影響，不僅影響門窗設備的正常工作，會造成門窗設備、塑鋼門窗設備、斷橋鋁門窗設備、中空玻璃設備液壓系統的嚴重損壞，不可小覷。
The four heads, double head and single head corner machines of the aluminum and aluminum doors and windows of the broken bridge will use hydraulic oil. Therefore, the quality of the hydraulic oil will have different influence on the quality of the door and window equipment, which not only affects the normal work of the door and window equipment, but also causes the door and window equipment, the plastic steel doors and windows equipment, the aluminum door of the bridge broken bridge. Serious damage to the hydraulic system of window equipment and insulating glass equipment should not be underestimated.
判斷液壓油優劣主要有以下幾點:
To judge the advantages and disadvantages of hydraulic oil, the following are the following points:
1、粘溫指數 也就是黏度隨著溫度變化的特性,變化越少越好,這樣就不會在低溫的時候需要很大的負荷,在高溫的時候無法形成有效的油膜。

1, the viscosity temperature index is the viscosity with the temperature change characteristics, the less the better the better, so that it will not need a lot of load at low temperature, when the high temperature can not form an effective oil film.

'

2、極壓性能 負荷高的液壓系統,需要有極壓性能的液壓油,也保證在高負荷的時候仍然有油膜保護設備。
2. Hydraulic system with extreme pressure and high load requires hydraulic oil with extreme pressure performance. It also ensures that oil film protection equipment is still available at high load.
3、抗泡性 如果液壓系統中有氣泡,氣泡在被高壓擠壓后爆裂,會嚴重損傷金屬表面。
3. Anti foaming property. If there are bubbles in the hydraulic system, the bubbles will burst after being extruded by high pressure, which will seriously damage the metal surface.
4、抗氧化性能 也就是氧化穩定性,氧化了容易產生油泥和其他雜質,腐蝕設備。
4, oxidation resistance is also oxidation stability, oxidation easily produces oil sludge and other impurities, corrosion equipment.
為保證門窗設備正常使用，所有門窗設備中使用的液壓油，都采用中石化的長城普力46號抗磨液壓油，僅液壓油一項，一套中空玻璃生產線，就多支出近伍佰元成本，雖然成本有所提高，但用戶在使用過程中，設備質量能得到有效保障。
In order to ensure the normal use of the door and window equipment, all the hydraulic oil used in the door and window equipment use the anti wear hydraulic oil of the the Great Wall Puli No. 46 of Sinopec. Only one hydraulic oil and a set of hollow glass production line will cost more than the Wu Bai yuan cost. Although the cost is improved, the quality of the equipment can be obtained in the process of use. Effective guarantee.
