經(jīng)過修理或重新組裝的調(diào)速器的初始操作在拆卸或修理后，在試驗(yàn)臺(tái)上測(cè)試調(diào)速器是非常重要的。如果沒有測(cè)試臺(tái)，可以在發(fā)動(dòng)機(jī)上進(jìn)行調(diào)速器測(cè)試。如果在發(fā)動(dòng)機(jī)上測(cè)試調(diào)速器，請(qǐng)小心手動(dòng)控制發(fā)動(dòng)機(jī)轉(zhuǎn)速，直到您證明調(diào)速器可以控制發(fā)動(dòng)機(jī)轉(zhuǎn)速。除了將普通連桿連接到輸出軸上外，還將一把鋸齒扳手連接到輸出上，以便用鋸齒扳手手動(dòng)控制發(fā)動(dòng)機(jī)轉(zhuǎn)速。當(dāng)確信調(diào)節(jié)系統(tǒng)完全工作時(shí)，拆下鋸齒扳手。在第一次操作維修后的調(diào)速器之前，檢查所有安裝步驟是否已正確完成（見第2章）。也請(qǐng)閱讀本章的全部?jī)?nèi)容。
從該設(shè)置開始，打開針閥一圈，然后手動(dòng)干擾調(diào)速器燃油設(shè)置。逐漸關(guān)閉針閥，直到調(diào)速器恢復(fù)到只有一個(gè)小的過沖或下沖的速度，并且：a.針閥在調(diào)速器上打開1/8到1/4圈，調(diào)速器上的油視鏡位于表盤的中心。b.在調(diào)速器上，針閥在3/8到3/4轉(zhuǎn)之間打開，調(diào)速器側(cè)面有一個(gè)油視鏡。補(bǔ)償調(diào)整決定關(guān)閉速度，針閥調(diào)整決定恢復(fù)時(shí)間。對(duì)于最靈敏的調(diào)速器控制，使用盡可能少的補(bǔ)償。補(bǔ)償過多會(huì)導(dǎo)致負(fù)載變化時(shí)出現(xiàn)過多的速度過沖和欠沖。關(guān)閉針閥的次數(shù)超過上述a.或b.中所示的次數(shù)，會(huì)使調(diào)速器在負(fù)載變化后緩慢恢復(fù)到正常速度。打開針閥的次數(shù)超過上述指示會(huì)降低調(diào)速器的穩(wěn)定性，并可能導(dǎo)致振蕩。一旦針閥調(diào)整正確，則無(wú)需更改設(shè)置，除非溫度發(fā)生較大的永久性變化，從而影響調(diào)速器油粘度。調(diào)整正確后，擰緊補(bǔ)償指針螺母，然后用銅墊圈重新安裝針閥檢修塞。塞子和墊圈將密封針閥周圍的漏油。
If a test stand is not available, testing of the governor can be done on the engine. If testing of the governor is done on the engine, be careful to manually control the engine speed until your have proven that the governor will control engine speed. Attach a serration wrench to the output shaft in addition to the normal linkage to manually control engine speed with the serration wrench. When satisfied that the governing system is fully operative, remove the serration wrench. Before operating a repaired governor for the first time, check that all installation steps have been correctly completed (see Chapter 2). Also read all of this chapter.
Closing the needle valve more than indicated in a. or b. above makes the governor slow to return to normal speed after a load change. Opening the needle valve more than indicated above decreases governor stability and can cause hunting. Once the needle valve adjustment is correct, it is not necessary to change the setting except for large, permanent changes in temperature which affect governor oil viscosity. When the adjustment is correct, tighten the compensation pointer nut and reinstall the needle valve access plug with a copper washer. The plug and the washer will seal oil seepage around the needle valve. Initial Operation for a Repaired or Reassembled Governor After disassembly or repair, it is very important to test the governor on a test stand.
From this setting, open the needle valve one turn and manually disturb the governor fuel setting. Gradually close the needle valve until the governor returns to speed with only a small overshoot or undershoot and: a. The needle valve is between 1/8 to 1/4 turn open on a governor with an oil sight glass located in the center of the dial panel. b. The needle valve is between 3/8 to 3/4 turn open on a governor with an oil sight glass located on the side of the governor. Compensation adjustment determines off-speed, and needle valve adjustment determines recovery time. For most responsive governor control, use as little compensation as possible. Too much compensation causes excessive speed overshoots and undershoots on load changes.
