PROSOFT 6105-WA-PDPS 通訊模塊
在UG杠桿調速器的初始操作之前，檢查之前的所有安裝步驟是否已成功完成，所有連桿是否牢固、布置和連接是否正確（見第2章）。也請閱讀本章的全部內容。將調速器加油至油視鏡上的頂部標記。6105-WA-PDPS 小心地（順時針）關閉針閥，然后將其打開1/2到3/4圈。松開固定補償調整指針的螺母，使其足以移動指針，并將指針設置在刻度的中間。擰緊螺母。如果更換調速器，6105-WA-PDPS 初始補償設置可以是剛剛拆下的調速器的補償設置。啟動發(fā)動機、渦輪機或其他類型的原動機時，要做好緊急停機的準備，以防止失控或超速，從而可能造成人身傷害、生命損失或財產損失。按照原動機制造商的說明啟動原動機。調整通常情況下，將新調速器投入使用的唯一調整是排出滯留空氣并調整補償，以獲得令人滿意的穩(wěn)定性和響應。所有其他操作調整都是在工廠測試期間根據(jù)原動機制造商的規(guī)范進行的，不需要進一步調整。本手冊的“發(fā)動機測試程序”部分給出了轉速下降、高速和低速停止以及停機螺母調整。除非您完全熟悉正確的程序，否則不要嘗試對調速器進行內部調整。補償調整針閥和調整指針是補償系統(tǒng)的可調整部件。它們的設置直接影響調速器的穩(wěn)定性6105-WA-PDPS 。補償必須根據(jù)特定的發(fā)動機和負載進行適當調整，以提供穩(wěn)定的運行。
作用在動力活塞底側的壓力油迫使其向上，并使輸出軸沿增加燃油的方向旋轉。5.來自輸出軸（6）的連桿升高補償調節(jié)桿（5），補償調節(jié)桿在支點（24）處樞轉，從而降低大補償活塞（21）。6.壓力油被施加到小補償活塞（20）的腔室中，從而升起浮動桿（18）的左端。7.依次升高pvp，關閉控制端口（18）。8.當油底殼油從緩沖器補償活塞總成（20和21）流經針閥（22）時，補償彈簧以與調速器桿（4）相同的速率將小補償活塞（20）返回到其正常居中位置。這將使先導閥柱塞（14）保持在其中心位置。9.這使先導閥襯套（15）中的控制端口被pvp（14）上的平臺覆蓋。10.輸出軸（6）和動力活塞（7）的運動停止在新的增加燃料位置，該位置是在負載增加的情況下以選定的速度設置運行原動機所需的。在負載減少或增加的任何一種情況下，補償系統(tǒng)都以相同的方式運行：大補償活塞的補償或移動量由補償調節(jié)（支點位置）控制。小補償活塞（20）恢復正常的速率由針閥（22）的調節(jié)來控制，即通過針閥的油流量。如果調整正確，補償系統(tǒng)將有效地調節(jié)使發(fā)動機達到所需輸出所需的燃油量，以適應負載的減少或增加或速度設置的變化。
Fill the governor with oil to the top mark on the oil sight glass. Close the needle valve carefully (clockwise), then open it 1/2 to 3/4 turn. Loosen the nut holding the compensation adjusting pointer enough to move the pointer and set the pointer in the middle of the scale. Tighten the nut. If replacing a governor, the initial compensation setting can be that of the governor just removed. Be prepared to make an emergency shutdown when starting the engine, turbine, or other type of prime mover, to protect against runaway or overspeed with possible personal injury, loss of life, or property damage. Follow the prime mover manufacturer’s instructions to start the prime mover. Adjustments Normally, the only adjustments for putting a new governor into service are bleeding trapped air and adjusting compensation to obtain satisfactory stability and response. All other operating adjustments were made during factory testing in accordance with the prime mover manufacturer’s specifications and should not require further adjustment.
In either case, a decrease or an increase in load, the compensation system operates in the same manner: the compensation or amount of movement of the large compensation piston is controlled by the compensation adjustment (the fulcrum position). The rate at which the small compensation piston (20) is returned to normal is controlled by the needle valve (22) adjustment—the rate of flow of oil through the needle valve (22). When correctly adjusted, the compensation system effectively regulates the amount of fuel necessary to bring the engine to the required output to adjust to a decrease or an increase in load or to a speed setting change.Before initial operation of the UG Lever governor, check that all previous installation steps are successfully accomplished and all linkages are secure and properly arranged and attached (see Chapter 2). Also read all of this chapter.
The pressure oil acting on the bottom side of the power piston forces it up and rotates the output shaft in the increase fuel direction. 5. Linkage from the output shaft (6) raises the compensation adjusting lever (5) which pivots at the fulcrum (24), lowering the large compensation piston (21). 6. Pressure oil is applied to the chamber of the small compensation piston (20), raising the left end of the floating lever (18). 7. The pvp is raised in turn, closing off the control port (18). 8. As sump oil flows through the needle valve (22) from the dashpot compensation piston assembly (20 and 21), the small compensation piston (20) is returned to its normal centered position by the compensation spring at the same rate as the speeder rod (4). This keeps the pilot valve plunger (14) in its centered position. 9. This keeps the control port in the pilot valve bushing (15) covered by the land on the pvp (14). 10. The output shaft (6) and power piston (7) movement is stopped in the new increase fuel position required to run the prime mover at the selected speed setting with the increase in load.
