測量方法
1流量測量
泵流量測定按GB/T3214的規(guī)定。
2壓力測量
泵的壓力系指換算到泵基準(zhǔn)面上的進(jìn)口、出口壓力。
臥式泵的基準(zhǔn)面是包括主桿中心線在內(nèi)的水平面。
立式泵的基準(zhǔn)面是包括吸入口中心線在內(nèi)的水平面。
2.1壓力表
泵的壓力和真空度的計量,一般采用彈簧壓力表和真空表,壓力表必須垂直安裝,測量儀表的選用應(yīng)遵守以下原則:
a)每一壓力表應(yīng)在它量程的*范圍內(nèi)使用(在壓力表滿刻度的40%~70%之間);
b)刻度盤相鄰的兩刻度線間隔在1.5 mm~3 mm之間;
c)分度間隔對應(yīng)的壓力示值zui大不超過量程的5%。
2.2取壓孔
泵進(jìn)出口取壓孔的位置以進(jìn)出口管徑尺寸D計算,應(yīng)位于進(jìn)出口法蘭2D的平直管線段上,1級試驗臺應(yīng)為開設(shè)4個靜壓孔的環(huán)形取壓。
取壓孔的直徑應(yīng)為2 mm~6 mm,長度不小于2.5倍取壓孔直徑,取壓孔的內(nèi)壁邊緣應(yīng)清除毛刺。
3轉(zhuǎn)速測量
泵轉(zhuǎn)速的測量按GB/T 3216的規(guī)定。
4軸功率測量
4.1軸功率測試按GB/T 3216的規(guī)定,采用轉(zhuǎn)矩和電功率測量。
4.2采用轉(zhuǎn)矩測量應(yīng)使轉(zhuǎn)矩和轉(zhuǎn)速做到同步。
4.3當(dāng)通過測量與泵直接連接的電動機(jī)輸入功率來確定泵的軸功率時,使用的電動機(jī)效率應(yīng)按GB/T1032和GB/T 1311規(guī)定的方法進(jìn)行確定。
5溫度測量
5.1 試驗介質(zhì)的溫度、泵零部件的溫度及環(huán)境溫度的測量,均應(yīng)選用精度為±1℃的溫度測量儀器,若選用溫度計時
,分度值不大于1℃。
5.2環(huán)境溫度應(yīng)在離開泵1 m~2 m,且和偶然流動的冷熱風(fēng)處測量。
5.3試驗介質(zhì)的溫度應(yīng)在進(jìn)口平直管段不小于4D的管路內(nèi)測量,溫度計應(yīng)與管路內(nèi)流體成45°逆流內(nèi)裝,且溫度計的
感溫部分應(yīng)全部置于介質(zhì)中。
6粘度測量
6.1運動粘度的測量按GB/T 265的規(guī)定進(jìn)行。
6.2試驗介質(zhì)的粘度應(yīng)定期進(jìn)行測定,并繪制粘溫特性曲線。
