However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement.

(d)在檢查完畢按速度、高度調(diào)節(jié)的工作情況后,應(yīng)當(dāng)先使靜壓系統(tǒng)與外界氣壓平衡后,再放掉全壓系統(tǒng)的壓力,在靜壓系統(tǒng)和全壓系統(tǒng)放氣過程中,力臂調(diào)節(jié)器電動(dòng)機(jī)也應(yīng)當(dāng)工作 。此時(shí)大力臂信號(hào)燈亮。此項(xiàng)檢查應(yīng)在飛機(jī) 液壓系統(tǒng)有壓力的情況下進(jìn)行。 d、 在力臂未到達(dá)大力臂之前,將轉(zhuǎn)換電門扳到“自動(dòng)”位置,電動(dòng)機(jī)構(gòu)應(yīng)當(dāng)繼續(xù)向大力臂方向工作,直到大力臂時(shí)為止,大力臂信號(hào)燈應(yīng)亮 。在液壓系統(tǒng)無壓力的條件下,允許力臂自動(dòng)調(diào)節(jié)裝置短時(shí)通電工作, 但調(diào)整片效應(yīng)機(jī)構(gòu)必須在中立位置,水平尾翼和駕駛桿一定要在中立、松開狀態(tài),否則 也會(huì)使電動(dòng)機(jī)過載。 使用手操縱時(shí),先將“力臂轉(zhuǎn)換”電門扳到“手動(dòng)”位置,然后向“ 大速度”或“小速度”方向扳動(dòng)“力臂操縱”電門即可。 ( 4)檢查調(diào)整片效應(yīng)機(jī)構(gòu)中立位置的長(zhǎng)度時(shí),應(yīng)以傳動(dòng)桿由里向外伸出剛好使效應(yīng)機(jī)構(gòu) 中立信號(hào)燈燃亮?xí)r,從殼體固定耳中心至傳動(dòng)桿六角螺帽內(nèi)邊緣的距離應(yīng)為 195177。 ( 4)將駕駛桿向前推到頭,向上滑動(dòng)“效應(yīng)機(jī)構(gòu)操縱”電門,直到調(diào)整片效應(yīng)機(jī)構(gòu)停止工作時(shí)止,松開駕駛桿后,駕駛桿應(yīng)停在向前傾斜的位置。 調(diào)整片效應(yīng)機(jī)構(gòu)通電檢查方法 ( 1) 上地面電源后,接通以下電門。 當(dāng)液壓下 降到 165 公斤/厘米 時(shí),助力系統(tǒng)液壓警告燈應(yīng) 燃亮,應(yīng) 急電動(dòng)液壓泵應(yīng)通電工作。按下按鈕后,繼 電器吸動(dòng),使助力液壓系統(tǒng)的副翼助力器電磁閥轉(zhuǎn)換為 2 號(hào)線通電的斷開位置,將助力液壓系統(tǒng)向 副翼助力器供壓的管路斷開。兩個(gè)液壓警告燈安裝在XSH16 信號(hào)顯示盒內(nèi)(紅色)。 應(yīng)急電動(dòng)液壓泵的工作電路受接觸器 的 觸頭控制,而接觸器的工作線圈電路則受應(yīng)急液壓泵電門和液控開關(guān)的觸頭 “ O” 與“ CB”控制。當(dāng)助力液壓系統(tǒng)的壓力升高到 195 公斤/厘米 時(shí),液控開關(guān)的觸頭轉(zhuǎn)換,接觸器釋放,應(yīng)急電動(dòng)液壓泵停止工作。 當(dāng)將副翼助力器電門由“斷開 ”位置向前扳到‘接通”位置時(shí),助力和主液壓系統(tǒng)副翼助力器電磁閥和均為 3 號(hào)線通電,電磁閥接通,將兩個(gè)系統(tǒng)的供壓管路與助力器的進(jìn)油管路連接,這時(shí)副翼可用液壓操縱,而 副翼助力器由哪個(gè)系統(tǒng)供壓,則由助力器內(nèi)的轉(zhuǎn)換活 門控制。 ( 2)接通 “力臂手操縱、斷開助力液 壓系統(tǒng)和液壓信號(hào) ”電門、“ 液壓表、第二組油箱和 副 油箱信號(hào)”電門。 ( 6)檢查完畢后 , 關(guān)閉電門 , 并拔下地面 電源插頭和 斷開地面液壓泵。
