柴油機消防泵的正確保養，特別是預防性的保養，是容易、經濟的保養，因此是延長使用壽命和降低使用成本的關鍵。日常維護可按以下步驟進行檢查燃油箱的燃油量——觀察燃油箱的存油量，根據需要添足。
檢查油底殼中機油平面——觀察油面是否達到機油標尺上的刻線標記，不足時應加到規定量，但不能超過標尺刻線的上限。
檢查噴油泵調速器機油平面——如果未達到規定的刻線標記，應添足機油（有的噴油泵調速器上沒有標尺，可省去此步驟）。
檢查水泵的注油點內是否有充足潤滑油脂——把柴油機循環水泵上的注油嘴卸下來，觀察里面的潤滑油脂是否充足，如不足，應用油槍向里面注入充足潤滑油脂。
檢查水箱中的水是否充足——發現水箱中的水不足應及時補充，加入的水應為清潔的淡水，如自來水或清潔的河水。如果直接用地下水，容易在水箱內形成水垢，影響冷卻效果而造成故障，因此，地下水軟化后方可使用。在北方（環境溫度低于零度），必須根據當地的低溫度配置適當凝點的防凍液，配方如下：
乙二醇 水 凝點℃
乙二醇防凍液 60 40 -55
55 45 -40
50 50 -32
40 60 -22
檢查三漏（水、油、氣）情況——檢查油管、水管接頭處的密封面，發現有滲漏，應該立即解決；如果排氣管、氣缸蓋墊片處增壓器有松動或漏氣現象，也應及時排除。
檢查蓄電池內酸液的情況——蓄電池內電解液的液面一般應高出極板頂面10～
檢查柴油機各附件的安裝情況——包括各附件安裝的穩固程度，地腳螺釘及與工作機械相聯接的牢固性。
檢查噴油泵傳動連接盤——檢查連接螺釘是否松動，如果松動，應重新校正噴油提前角，并擰緊連接螺釘。
The correct fire pump diesel engine maintenance, preventive maintenance in particular, is the easiest, most economical maintenance, and therefore extend the service life and reduce the cost of the key. Routine maintenance can be carried out the following steps to check the fuel quantity of fuel tank - to observe the survival of the oil fuel tank, according to the need for adequate Tim.
Check the oil sump in the plane - to observe whether the oil gauge oil line engraved on the tag, lack of provisions to be added to the volume, but can not exceed the upper limit of scale engraved lines.
Check the oil injection pump governor plane - if it has not reached the provisions of the engraved line marking, should be full-tim oil (some injection pump governor does not scale, this step can be omitted).
Check the oil pump if there were sufficient points Lubricants - circulating water pump on the diesel injection glib unloaded to observe the inside of the adequacy of Lubricants, such as the lack of application of the oil inside the gun to inject sufficient grease lubricants.
Check the radiator, the adequacy of the water - found that less than a tank of water should be added that the added water should be clean fresh water, such as tap water or clean water. If the direct use of groundwater, easily scale to form in water tanks, cooling effect caused by the impact of failure, therefore, before the use of underground water to soften. In the north (the ambient temperature is lower than zero), the minimum must be based on local configuration appropriate solidifying point temperature of the antifreeze, formula is as follows:
Glycol hydrogel point ℃
60 40 -55 glycol antifreeze
55 45 -40
50 50 -32
40 60 -22
Third, leakage inspection (water, oil, gas) situation - Check oil, water pipes joint of the sealing surface and found that leakage should be immediately resolved; if the exhaust pipe, cylinder head gasket turbocharger Department have loose or missing gas phenomena, but also should be ruled out.
Check the battery acid in the case - the liquid electrolyte batteries in general should be above the top plate 10 ~
Inspection of the annex to the installation of diesel engine situation - including the installation of the annex to the stability of screws in the foot and connected with the mechanical work of the firm.
Check the fuel pump connected disk drive - Check whether the loosening of screw connections, if loose, should be re-correction fuel injection advance angle, and tighten the screw connection.
