一、天然氣發(fā)電機組三角橡膠帶張力的調(diào)整:
1、 Adjustment of the tension of the triangular rubber belt for natural gas generator sets:
發(fā)動機三角橡膠帶的張緊力,是利用風扇架上的調(diào)節(jié)螺釘改變風扇軸在座駕上的位置進行調(diào)整。正確使用和張緊三角橡膠帶,對延長三角橡膠帶的使用壽命有利,一般使用期限不少于3500h。當三角橡膠帶出現(xiàn)剝離分層和因伸長量過大無法達到規(guī)定的張緊度時應(yīng)即換新。
The tension of the engine triangular rubber belt is adjusted by changing the position of the fan shaft on the driver's seat using the adjusting screws on the fan frame. Proper use and tensioning of triangular rubber belts is beneficial for extending their service life, with a general service life of no less than 3500h. When the triangular rubber belt experiences delamination and cannot reach the specified tension due to excessive elongation, it should be replaced immediately.
發(fā)動機工作時,三角橡膠帶應(yīng)保持一定的張緊程度。正常情況下,在三角橡膠帶中段加29-49N(3-5kgf)的壓力,膠帶應(yīng)能按下10-20mm距離。過緊將引起充電發(fā)電機、風扇和水泵上的軸承磨損加劇;太松則會使所驅(qū)動的附件達不到需要的轉(zhuǎn)速,導(dǎo)致充電發(fā)電機電壓下降,風扇風量和水泵流量降低,從而影響發(fā)動機的正常運轉(zhuǎn),故應(yīng)定期對三角橡膠帶張緊力進行檢查和調(diào)整。
When the engine is working, the triangular rubber belt should maintain a certain degree of tension. Under normal circumstances, apply a pressure of 29-49N (3-5 kgf) to the middle section of the triangular rubber belt, and the tape should be able to press for a distance of 10-20mm. Excessive tightening will cause increased bearing wear on the charging generator, fan, and water pump; If it is too loose, it will cause the driven accessories to not reach the required speed, leading to a decrease in the voltage of the charging generator, a decrease in the fan air volume and water pump flow rate, thereby affecting the normal operation of the engine. Therefore, the tension of the triangular rubber belt should be checked and adjusted regularly.
因此,天然氣發(fā)電機組用戶在購買和調(diào)換三角橡膠帶時,應(yīng)注意新帶的型號和長度與原用的三角橡膠帶一樣,如一組采用相同兩根以上的三角橡膠帶,還應(yīng)挑選實際長度相差不多為一組,否則每根三角橡膠帶的張力不均容易損壞。
Therefore, when purchasing and replacing triangular rubber belts for natural gas power generation units, users should pay attention to the model and length of the new belt being the same as the original triangular rubber belt. If a group uses the same two or more triangular rubber belts, they should also choose a group with no more than the actual length difference, otherwise the tension of each triangular rubber belt is uneven and easy to damage.
二、天然氣發(fā)電機組機油壓力的調(diào)整:天然氣發(fā)動機,在標定轉(zhuǎn)速時的機油壓力應(yīng)為0.245-0.343mpa(2.5-3.5kgf/cm2),在750-850r/min時的機油壓力應(yīng)不小于0.05mpa(0.5kgf/cm2),發(fā)動機運行時,如與上述規(guī)定壓力范圍不符時,應(yīng)及時進行調(diào)整。調(diào)整時,先擰下調(diào)壓閥上的封油螺帽,松開鎖緊螺母,再用起子轉(zhuǎn)動調(diào)節(jié)螺栓。旋緊調(diào)節(jié)螺栓,機油壓力升高;旋出則降低。調(diào)整到規(guī)定范圍為止。調(diào)整后,將鎖緊螺母擰緊,并裝上封油螺帽。
2、 Adjustment of oil pressure for natural gas generator sets: For natural gas engines, the oil pressure should be 0.245-0.343 MPa (2.5-3.5 kgf/cm2) at the rated speed, and not less than 0.05mpa (0.5 kgf/cm2) at 750-850 r/min. If the engine is running and does not meet the specified pressure range, adjustments should be made in a timely manner. When adjusting, first tighten the sealing nut on the pressure regulating valve, loosen the locking nut, and then use a screwdriver to turn the adjusting bolt. Tighten the adjusting bolt to increase the oil pressure; Rotate it out to lower it. Adjust to the specified range. After adjustment, tighten the locking nut and install the sealing nut.
