(1)轉子的檢查

(1) Rotor inspection

轉子對地短路的檢查。用電阻表1×KΩ擋檢查轉子1的滑環3與轉子1軸頭之間的電阻應為∞,否則闡明轉子線圈短路,應改換。

Inspection of short circuit between rotor and ground. The resistance between the sliding ring 3 of rotor 1 and the shaft head of rotor 1 should be checked by resistance table 1 *K_. Otherwise, the short circuit of rotor coil should be replaced.

D88尊龙轉子線圈斷路與短路的檢查。用電阻表2的1×Ω擋,檢查轉子1兩個滑環3之間的電阻值,應在2.8-3.0Ω之間。假如電阻值在kΩ范圍,則表示轉子1斷路,400千瓦柴油發電機組,假如電阻值低于上述值時,則表示轉子1短路。

D88尊龙Inspection of breaking and short circuit of rotor coil. The resistance value between two slip rings 3 of rotor 1 should be between 2.8 and 3.0_when checking with 1 *_block of resistance meter 2. If the resistance value is in the range of k_, it means that the rotor 1 is open and the 400 kW diesel generator set is short-circuited if the resistance value is lower than the above value.

D88尊龙轉子滑環磨損的檢查。檢查滑環3外表能否有傷痕,并用卡尺2丈量,若磨損傷痕深度超越0.22mm時,則應改換轉子1或滑環3。

D88尊龙Inspection of rotor slip ring wear. Check the appearance of slip ring 3 and measure it with caliper 2. If the depth of wear scar exceeds 0.22mm, the rotor 1 or slip ring 3 should be replaced.

(2)定子的檢查

(2) Inspection of stator

定子線圈對地短路的檢查。以捷達轎車為例,用電阻表的1×KΩ擋逐一檢查定子線圈的鐵芯1與定子線圈抽頭2、3和4之間的電阻,均應為無量大,若有較小的阻值,表示定子線圈對地短路,應改換定子線圈。

D88尊龙Inspection of short circuit between stator coil and ground. Taking Jetta as an example, the resistance between the core 1 of the stator coil and the taps 2, 3 and 4 of the stator coil should be inspected one by one with the 1 *K_block of the resistance meter. If there is a small resistance value, it means that the stator coil is short-circuit to the ground, the stator coil should be replaced.

定子線圈斷路的檢查,用電阻表的1×Ω擋逐一檢查定子線圈抽頭1和2、1和3、2和3,所顯現的值必需為0。若丈量值為KΩ量級時,則標明斷路,應改換定子。

Stator coil circuit break check, check stator coil taps 1 and 2, 1 and 3, 2 and 3 one by one with 1 * _block of resistance meter, the value must be 0. If the measurement value is in the order of K_, the open circuit is marked and the stator should be changed.

(3)二極管板的檢查

(3) Inspection of Diode Board

D88尊龙以捷達為例,運用多用實驗器5,同時按下電阻和電壓丈量按鈕8和9。

Take Jetta as an example, using multi-purpose tester 5, while pressing resistance and voltage measurement buttons 8 and 9.

檢測正二極管:黑端子6接正極散熱片1(相當于B+)(正極二極管負極),紅端子7逐一接結點2(正極二極管正極)。

D88尊龙Detection positive diode: black terminal 6 is connected with positive radiator 1 (equivalent to B+) (positive diode negative), red terminal 7 is connected with node 2 (positive diode positive).

檢測負二極管:紅端子7接負極散熱片3(負二極管正極),黑端子6逐一接結點2(負二極管負極)。

D88尊龙Detection negative diode: red terminal 7 is connected with negative radiator 3 (negative diode positive), black terminal 6 is connected with negative diode negative 2 (negative diode negative).

D88尊龙檢測勵磁二極管:黑端子6接在勵磁端4(即D+)(勵磁二極管負極),紅端子7逐一接結點2(勵磁二極管正極)。

D88尊龙Detection excitation diode: black terminal 6 is connected to excitation terminal 4 (D+) (excitation diode negative pole), red terminal 7 is connected to node 2 (excitation diode positive pole) one by one.

一切測試均需停止三次,且其值都應為50-80Ω,否則改換二極管板。

All tests should be stopped three times, and the value should be 50-80_, otherwise the diode board will be replaced.

(4)炭刷的檢查

(4) Carbon Brush Inspection

用卡尺1檢查炭刷2的長度。規范值長度為13mm,運用極限為5mm,超越極限,應予改換。

D88尊龙Check the length of carbon brush 2 with caliper 1. The length of the standard value is 13 mm, and the application limit is 5 mm. If it exceeds the limit, it should be replaced.

(5)電壓調理器檢查

(5) Voltage Regulator Inspection

在蓄電池充電正常及發電機傳動皮帶張緊正常的狀況下,當發起機轉速高于怠速且充電指示燈仍不熄滅時,從發電機上拆下調理器。用一根導線將調理器的接柱“F”與接柱“一”銜接起來,再將調理器裝在發電機上。此時調理器處于不正常狀態下,起動發起機并使轉速進步,如充電指示燈熄滅,則表示發電機工作正常,毛病在調理器方面,濰柴發電機;若充電指示燈仍亮,表示毛病在發電機方面,而不在調理器方面。調理器發作毛病時,應整個改換。

When the battery is charged normally and the belt of the generator is tensioned normally, the regulator is removed from the generator when the speed of the starter is higher than the idle speed and the charging indicator is not extinguished. A conductor is used to connect the connecting post "F" and "1" of the conditioner, and then the conditioner is installed on the generator. At this time, the conditioner is in an abnormal state, starting the starter and improving the speed. If the charging indicator lights out, it means that the generator works normally. If the charging indicator is still on, it means that the fault is in the generator, not in the conditioner. When the conditioner breaks down, it should be replaced entirely.

(6)軸承的檢查

(6) Bearing inspection

檢查軸承的損壞狀況,如損壞應改換。

D88尊龙Check the damage condition of the bearing, if it is damaged, it should be replaced.

(7)發電機傳動皮帶的檢查

(7) Inspection of Generator Drive Belt

檢查V型皮帶情況,若發現以下缺陷時必需立刻改換:

Check the V-belt condition and replace it immediately if the following defects are found:

基層裂紋(裂痕、芯部斷裂、槽斷面開裂);

D88尊龙Base cracks (cracks, core cracks, groove section cracks);

D88尊龙位置別離(掩蓋層、拉繩);

Location separation (cover layer, pull rope);

基座開裂;拉繩散線;

Base cracking; cable splitting;

側面磨損(散線、側面資料損壞、側面硬化、側面發滑、上外表裂紋)。

Side wear (scatter line, side data damage, side hardening, side slippage, upper surface crack).

當皮帶放到皮帶輪上時,皮帶的內徑與皮帶輪槽底應有間隙,若無間隙時必需改換皮帶。

When the belt is placed on the pulley, there should be a gap between the inner diameter of the belt and the bottom of the pulley groove. If there is no gap, the belt must be replaced.
