攜帶式黏度計
產品型號:Centistokes Model #38 VISGAGE
產品分類:自動化設備/產業機械 / 檢測設備 / 檢測、量測設備及其另件
產品特色
VISGAGE黏度計用於現場潤滑油的黏度檢測非常快速且便利,不需使用到溫度計或秒錶。VISGAGE是專門設計來測試全新和使用過但不含污泥的油的黏度,可被用來檢測任何低黏度的主軸油或高黏度的齒輪油。定期使用黏度計檢測潤滑油可以確保油品品質。
潤滑油最重要的特性是它的黏度。對於厚的和薄的保護膜的潤滑油薄膜的形成是很重要的。黏度會影響軸承、汽缸和齒輪的熱能產生。也會影響油的密封性和耗損率,更有甚者,會影響在冷開機狀態下所需功率的獲得。
VISGAGE黏度計特點:
容易操作和清理
無需試劑、電力和秒錶
可因應需求而予以客製化
在將潤滑油加入前可先進行粘度測試
決定在柴油引擎機曲軸箱油中的燃油或冷卻劑稀釋油
確認潤滑油多種雜質的黏度
當混合大量汽油時,校驗所需粘度
操作簡易
VISGAGE的操作原理很簡單,與已知黏度的參考油做比較,而測得油樣的黏度,黏度讀值為室溫(27℃)直接測得的40℃黏度(cSt),不需要再經過計算,量測精度為95%以上,細心的操作者可以獲得更精確的結果。

注意:不要直接從曲軸箱或油箱汲取熱油到黏度計 。
將少量的油注入(如圖1)一個容器中 ,當油溫約為27℃( 80 ° F) 時,將黏度計的油嘴插入油(液)中。
最好的量測結果是在27℃( 80 ° F )的溫度下進行測試。
將油嘴插入油中後,慢慢地拉出柱塞(如圖1)。如果試管中出現氣泡, 將黏度計顛倒放置(如圖2),並擠壓出空氣。將油嘴再度插入油中,慢 慢拉出柱塞,使試管完全充滿油,不要有氣泡存在。

調整柱塞,並使小鐵球停滯在刻度為零的位置(如圖3)。放置黏度計 於木盒中,柱塞拉桿必須伸出木盒位於右側位置(如圖4),關閉並鎖上保險,使二邊試管的油能保持同樣的溫度。

angle between 30 and 45 degrees so spheres move through the oils toward the line at left side of scale. (NOTE: To develop your proficiency, make VISGAGE tests using a standard fluid of specific viscosity for determining best angle of tilt.) |
|
Give spheres the run of the oils. As the leading sphere approaches the line (38.6 line/76.5 line) at left of scale, gradually move the instrument to horizontal position to stop leading sphere exactly on the line. |
Read point on scale opposite position of other sphere. The reading gives the viscosity of the tested oil directly in Centistokes at 40°C. After a few trials, any operator can check the viscosity of oils to an accuracy of 95°F or better; and if skillful, to even closer accuracy. |
HOW TO BE CERTAIN THAT OILS ARE THE SAME TEMPERATURE: |
Slowly raise plunger end of VISGAGE to an angle between 30 to 45 degrees. Take two or three readings. If readings repeat, the oils are the same temperatures. If readings do not repeat, allow another few minutes to equalize temperature until a few readings repeat. The final repeat reading indicates the viscosity of the test oil directly in Centistokes at 40°C. |
HOT OILS: |
WARNING: Do not immerse VISGAGE in hot oil/ or hot water to equal/is temperatures. Do not heat VISGAGE above 40°C. |
CLEANING: |
The VISGAGE is self-cleaning. When the oil is discharged after a test, returning the plunger to its original position effectively cleans the wall of the test tube. A small a- mount of oil will remain in the bore of the nozzle. To discharge this, fill the test tube with the next oil to be tested, discharge and discard it. This will clean the nozzle of the previous oil before the new test is made.
Non-use of the VISGAGE over a period of time with residue oil in the test tube may gum the sphere and the wall of the tube. To remove it, draw into the test tube a few charges of light oil or kerosene to dissolve the residue. Do not use straight gasoline or naphtha. |
DARK COLORED OILS: |
|
Dark colored oils in the test tube may make it difficult to see the sphere. To overcome this, follow standard test procedure under READING. Then, with your back to the light (Fig. 6) and full light on the scale, (Fig. 7 & 8) tilt reference tube toward you 90 degrees to bring the sphere in the test tube into sight. The point on the scale corresponding to the position of the sphere indicates the viscosity of the test oil direct at which it was rated in Centistokes at 40° C. (Fig. 8) |
The VISGAGE is designed and constructed to test the viscosity of new and used oil/s but not sludge. |
Whenever the sphere in the test tube can no longer be seen, you will know the oil is so badly fouled with contaminants that it needs to be changed immediately or cleaned by any of the appropriate cleaning methods. |
|
VISCOSITY INDEX (VI): |
The reference tube contains certified oil with a viscosity index of 95 VI. Best accuracy is achieved when the oil being tested has a VI near the VI of the reference oil, and several identical readings on the scale indicate temperatures of both tubes are equal. If the VI's of the oils are far apart (for example, 95 VI in reference tube, 40 VI in test oil), warm VISGAGE to 40° C, and then take readings. |

HEATING THE VISGAGE: The temperature of both the reference tube and the drawn oil must be the same before taking a eading. Certain oils may require heating the instrument to 40°C to obtain accurate results.
Place the VISGAGE in its draft-proof case with a thermometer under a lamp. Test your oil viscosity when temperature reaches 40°C. The VISGAGE should NOT be heated over 40°C. |
如何加熱黏度計: r兩個試管的油溫在讀值時必須是相同的。某些油可能需要將儀器加熱到40 ° C以獲得準確 的結果。將黏度計與溫度計一同放入木盒後,放置於燈光下,當溫度達到40 °C時,即可 開始進行測試。黏度計不能加熱超過40 °C。
OVER-HEATING WILL CAUSE THE VISGAGE TO GO OUT OF CALIBRATIO |
過熱會導致黏度計超過校驗精確度範圍。
參考試管中的油是密封住的,油中的小氣泡可以允許油加熱膨脹,加熱過度會使密封失效。 從曲軸箱或油箱汲取的熱油必須先注入其他容器經過冷卻後,才能使用黏度計進行測試。
The VISGAGE is calibrated at 27 ° C. |
VISGAGE黏度計是在27℃溫度下進行調校。
ATTENTION OPERATORS: |
操作注意事項:
Develop your proficiency by first practicing with oils of a known viscosity. A standardized testing procedure and an angle between 30 and 45 degrees will then be established.
Oils lighter than reference tube oil are easy to test. Stop the faster sphere at the 38.6 or 76.5 line. The sphere in the heavier oil will then mark your viscosity. |
先從已知黏度的潤滑油開始練習,這樣就可以慢慢熟悉標準的測試程序,並確認30到45度的 傾斜測試角度。若測試油比參考油的黏度低,則比較容易測試。跑在前面的小鐵球必須剛好停在38.6線/76.5線上,在黏度較高的潤滑油裡的小鐵球所停滯的位置即為黏度值。
維修注意事項:
如果儀器損壞,請小心地用紙盒包裝以防止更進一步的損壞,然後寄回原廠。原廠會維修並重新校驗。
VISGAGE黏度計非常便於攜帶且具實用性,出廠前均在實驗室內進行組裝及校驗。因為此黏度計跟溫度計一樣,對震動很敏感,必須小心操作,切勿搖晃玻璃管。
