濟(jì)南裝載機(jī)液壓油質(zhì)量直接影響著裝載機(jī)的正常工作,在選擇液壓油的時(shí)候一定要注意液壓油的質(zhì)量,液壓油粘度過低會(huì)使零部件摩擦嚴(yán)重,粘度過高會(huì)導(dǎo)致啟動(dòng)困難及油泵吸油不良,以確保機(jī)械的正常運(yùn)行。那么應(yīng)該如何判斷液壓油的粘度呢?
1、玻璃板傾斜法:取一塊干凈的玻璃板,將其水平放置,并將被測(cè)液壓油滴一滴在玻璃上,同時(shí)在旁邊再滴一滴標(biāo)準(zhǔn)液壓油,然后將玻璃板傾斜,并注意觀察:如果被測(cè)油液的流速和流動(dòng)距離均比標(biāo)準(zhǔn)油液大,則說明其粘度比標(biāo)準(zhǔn)油液低,反之,則說明其粘度比標(biāo)準(zhǔn)油液高。
Take a clean glass plate, which was placed horizontally and tested hydraulic oil drop by drop on the glass, while a drop in again next standard hydraulic oil, then tilt the glass and observe: If the oil tested than the standard flow rate and the flow of oil from the large, then the viscosity of the oil is lower than the standard, and vice versa, then the oil having a viscosity higher than the standard.
2、玻璃瓶倒置法:將被測(cè)的液壓油液與標(biāo)準(zhǔn)油液分別盛在兩個(gè)大小和長(zhǎng)度相同的透明玻璃瓶中,再用塞子將兩瓶口堵上。將兩瓶并排放置在一起,然后同時(shí)迅速將兩瓶倒置。如果被測(cè)液壓油在瓶中的氣泡比標(biāo)準(zhǔn)油液在瓶中的氣泡上升得快,則說明油液的粘度比標(biāo)準(zhǔn)油液粘度低,反之,則說明油液粘度比標(biāo)準(zhǔn)油液粘度高;若兩種油液氣泡上升的速度接近,則說明粘度也相似。
Hydraulic fluid to be tested with a standard oil were served in the same size and length of two transparent glass bottles, and then plug the two bottle stuffed. The two bottles side by side together, and then quickly while two bottles upside down. If the measured hydraulic oil in the bottle of bubbles in the bottle than the standard oil bubbles rise quickly, then the viscosity of the oil is lower than the standard oil viscosity, and vice versa, then the oil viscosity is higher than standard oil viscosity; If the two kinds of oil bubble rise velocity close, then the viscosity is also similar.
