MP904A5047 带定位器的标准操作器MP904A:带定位器的标准操作器。MP904B:不带定位器的标准操作器。大安全气压25b /in2 (172kpa)起点压力MP904A:继电器可调3至101b/in2(20至70 kPa)。MP904B:出厂设置为2、3或7磅/英寸(15、20或50kpa)操作范围见表1和表2阻尼器额定载荷(见表1和表2)尼韦尔smaduflow减震器的额定减震器负载由所有减震器的“B” 尺寸总和表示。( "A"尺时平行,"B" 尺寸垂直于叶长度。)例子: ."A"尺寸为108英寸(2743毫米),"B” 尺寸为36英寸(914毫米)的风管使用三个36。D640阻尼器部分为"A" 尺寸,每个"B” 尺寸为36英寸(914毫米)所有三个部分的“B" 尺寸:3 x 36= 108英寸。(3 X 914 =2743 mm)。表2显示一个MP904Boperator足够用于调制服务,或两个位置服务,弹簧范围为3至13或7至13lb/in2(21至90或48至90 kPa)。2到7 [b/in(14到48 kPa)的弹簧范围需要两个电机。MP904A: Standard operator with locator. MP904B: Standard operator without locator. The starting pressure MP904A at atmospheric safety pressure of 25b/in2 (172kPa): the relay can be adjusted from 3 to 101b/in2 (20 to 70 kPa). MP904B: Factory set to 2, 3, or 7 pounds per inch (15, 20, or 50kpa) operating range as shown in Table 1 and Table 2. The rated load of the Niwell smaduflow shock absorber is represented by the sum of the "B" dimensions of all shock absorbers. (When "A" is parallel, "B" is perpendicular to the length of the blade.) Example: The size of 'A' is 108 inches (2743 millimeters), The duct with a "B" size of 36 inches (914 mm) uses three 36s. The D640 damper section is of "A" size, and each "B" size is 36 inches (914 mm). All three sections have a "B" size of 3 x 36=108 inches. (3 X 914=2743 mm). Table 2 shows that one MP904Boperator is sufficient for modulation service, or two position service, with a spring range of 3 to 13 or 7 to 13lb/in 2 (21 to 90 or 48 to 90 kPa). 2 to 7 [b/in (14 to 48 kPa) The spring range requires two motors.
