1. Prepare two glass measuring cylinders for use. If the measuring cylinder cannot be found for a while, two identical vials can be used instead.

2、拆下供油量過大（或過小）一缸與噴油器連接的高壓油管接頭。

2. Remove the high-pressure oil pipe joint between cylinder 1 with excessive fuel supply (or too small) and fuel injector.

3、再拆下供油量正常一缸與噴油器連接的高壓管接頭。

3. Then remove the high-pressure pipe joint between cylinder 1 with normal fuel supply and fuel injector.

4、將兩個油管端頭分別插入兩個量筒（或小瓶）內。

4. Insert the two tubing ends into two measuring cylinders (or vials) respectively.

5、用起動機帶發動機轉動使噴油泵泵油。

5. Use the starter to turn the engine to make the fuel injection pump pump oil.

6、當量筒（或小瓶）內有柴油時，將量筒放在水平臺上比較油量的多少，便可了解供油量是否過大或過小。如果用小瓶代替，可對其進行稱量比較。可改變柴油發電機組噴油泵油量調節拉桿（即齒桿）上拔叉（或齒圈）的相對位置進行調整。對P_型泵可通過轉動法蘭套筒進行調整。

6. When there is diesel oil in the equivalent cylinder (or small bottle), put the measuring cylinder on the horizontal platform to compare the amount of oil, then we can know whether the fuel supply is too large or too small. If a small bottle is used instead, it can be weighed and compared. The relative position of the fork (or gear ring) on the adjusting rod (gear rod) of the fuel injection pump of diesel generator set can be adjusted. To P_ The pump can be adjusted by turning the flange sleeve.

在防雨型柴油發電機組操作過程中，根據經驗，應注意以下幾點：

During the operation of rain proof diesel generator set, the following points should be paid attention to according to experience:

1、松開拔叉（或齒圈、或法蘭套筒）的固定螺釘，稍微移動便可改變供油量，切不可移動過大，否則難調整準確（如有需要，可先標記出初始位置，便于對照）。

1. Loosen the fixed screw of fork (or gear ring, or flange sleeve) and slightly move it to change the oil supply quantity. Do not move it too much, otherwise it is difficult to adjust accurately (if necessary, mark the initial position for comparison).

2、每次調整后，須確認固定螺釘的擰緊度。

2. After each adjustment, the tightening degree of the fixing screw must be confirmed.

3、在進行防雨型柴油發電機組供油量的調整時，應使得油量不得高于標準供油量。這是因為調整是在低速下進行的，考慮到漏油等諸多因素的影響，此時允許有較大的不均勻度（30%），但高速時受節流作用等因素的影響，其允許不均勻度較小（3%）。如果在低速時的油量高于標準供油量，那么高速油量可能會有較大變化，甚至超過額定供油量。

3. When adjusting the oil supply of rain proof diesel generator set, the oil quantity should not be higher than the standard oil supply. This is because the adjustment is carried out at low speed. Considering the influence of many factors such as oil leakage, a large nonuniformity (30%) is allowed at this time, but at high speed, due to the influence of throttling and other factors, the allowable unevenness is small (3%). If the fuel quantity at low speed is higher than the standard fuel supply, the high-speed fuel supply may have a large change, or even exceed the rated fuel supply.

4、如果在同一防雨型柴油發電機組上大供油量與小供油量相差較大，不要急于調整，可先將兩分泵的出油閥對調安裝，進行檢查比較，這樣做有時也可以改變供油量。若對調后沒有改變供油量，則需對兩分泵逐一進行調整。

4. If there is a big difference between the large oil supply and the small oil supply on the same rain proof diesel generator set, do not rush to adjust it. First, the oil outlet valves of the two pumps can be adjusted and installed for inspection and comparison. Sometimes, the fuel supply quantity can be changed by doing so. If there is no change in oil supply after the adjustment, the two pumps should be adjusted one by one.
