PROSOFT MVI46-GSC 通用串行
將速度設(shè)定軸移動(dòng)到指定的低速設(shè)定值。將低速止動(dòng)桿滑入位置，盡可能靠近上部止動(dòng)螺釘（低速止動(dòng)螺釘）的凸臺(tái)。13.使用低速止動(dòng)螺釘對(duì)低速設(shè)置進(jìn)行微調(diào)（逆時(shí)針以降低速度），并用螺母（23）鎖定。14.如果不需要停機(jī)，將停機(jī)螺母（30）鎖在停機(jī)桿頂部。如果使用自鎖螺母，將其擰到停機(jī)桿上，直到螺母上方有1/4”（6 mm）的螺紋。要將螺母設(shè)置為停機(jī)操作，請(qǐng)調(diào)整低速止動(dòng)螺釘，使調(diào)速軸在低于最低轉(zhuǎn)速設(shè)置的情況下旋轉(zhuǎn)10°。將螺母向下擰到調(diào)速器螺塞的頂部，使其在低于最低轉(zhuǎn)速設(shè)定值5°時(shí)停機(jī)。將螺母鎖定到位。如果調(diào)速器在出廠時(shí)設(shè)置為停機(jī)，則止動(dòng)桿上有一個(gè)中心沖頭壓痕。設(shè)置低速并調(diào)整止動(dòng)桿，直到通過前蓋板上的孔可以看到壓痕。將螺母向下擰到調(diào)速器螺塞上，以獲得停機(jī)。
如果在發(fā)動(dòng)機(jī)上測(cè)試調(diào)速器，則根據(jù)制造商的說明啟動(dòng)原動(dòng)機(jī)。運(yùn)行調(diào)速器，直到達(dá)到工作溫度。6.檢查調(diào)速器在正常工作速度下的油壓是否為110–120 psi/758–827 kPa（UG-10為135–150 psi/931–1034 kPa）。7.關(guān)閉針閥（148），并將其打開至剛好引起小的擺動(dòng)。使用十字螺絲刀。如果必須使用普通螺絲刀，請(qǐng)確保僅使用針閥的淺槽，以避免損壞孔內(nèi)的螺紋和針閥。螺紋或針閥損壞會(huì)導(dǎo)致調(diào)速器擺動(dòng)。讓原動(dòng)機(jī)擺動(dòng)約30秒，以排出調(diào)速器油道中的滯留空氣。8.關(guān)閉針閥，再打開半圈。如果調(diào)速器繼續(xù)擺動(dòng)，重復(fù)步驟6。9.調(diào)整補(bǔ)償制度。請(qǐng)參閱本章中的補(bǔ)償調(diào)整。UG杠桿調(diào)速器恒定運(yùn)行的最大轉(zhuǎn)速為1500 rpm。10.移動(dòng)速度設(shè)定軸以獲得指定的高速。止動(dòng)桿已安裝在調(diào)速器總成的軸上?，F(xiàn)在滑動(dòng)軸鋸齒上的高速止動(dòng)塊，使其盡可能靠近凸臺(tái)和左側(cè)止動(dòng)螺釘（高速止動(dòng)螺釘）。11.使用高速止動(dòng)螺釘對(duì)高速設(shè)置進(jìn)行微調(diào)（逆時(shí)針增加），并用螺母（23）鎖定。
If shutdown is not required, lock shutdown nuts (30) together at the top of the shutdown rod. If a self-locking nut is used, thread it onto the shutdown rod until 1/4” (6 mm) of threads is above the nut. To set the nut(s) for shutdown operation, adjust the low speed stop screw to allow 10° rotation of the speed adjusting shaft below minimum speed setting. Thread the nut down on top of the speeder plug to obtain shutdown at 5° below minimum speed setting. Lock the nut in place. If the governor was factory set for shutdown, there is a center punch indentation in the stop lever. Set the low speed and adjust the stop lever until the indentation is visible through the hole in the front cover plate. Thread the nuts down onto the speeder plug to obtain shutdown.
Move the speed setting shaft to obtain the specified high speed. The stop levers have been installed on the shaft at governor assembly. Now slide the high speed stop on the shaft serration as close to the boss and the left hand side stop screw (high speed stop screw) as possible. 11. Use the high speed stop screw to make fine adjustments to the high speed setting (counterclockwise to increase) and lock with nut (23). 12. Move the speed setting shaft to the specified low speed setting. Slide the low speed stop lever into position as close to the boss of upper stop screw (low speed stop screw) as possible. 13. Use the low speed stop screw to make fine adjustments to the low speed setting (counterclockwise to decrease speed) and lock with nut (23).
If the governor is tested on the engine, start the prime mover according to the instructions from the manufacturer. Run the governor until it is at operating temperature. 6. Check that the governor has 110–120 psi/758–827 kPa (135–150 psi/931– 1034 kPa for UG-10) oil pressure at normal operating speed. 7. Close the needle valve (148) and open it just enough to cause a small hunt. Use a Phillips screwdriver. If a plain screwdriver must be used, make sure to use only the shallow slot of the needle valve to avoid damage to the threads inside the bore and to the needle valve. Damage to the threads or to the needle valve will cause the governor to hunt. Let the prime mover hunt for approximately 30 seconds to bleed trapped air from the governor oil passages. 8. Close the needle valve and open it again one-half turn. If the governor continues to hunt, repeat step 6. 9. Adjust the compensation system. See Compensation Adjustments in this chapter. Maximum speed for constant operation for the UG Lever governor is 1500 rpm.
