柴油机消防泵的正确保养，特别是预防性的保养，是容易、经济的保养，因此是延长使用寿命和降低使用成本的关键。日常维护可按以下步骤进行检查燃油箱的燃油量——观察燃油箱的存油量，根据需要添足。
　　检查油底壳中机油平面——观察油面是否达到机油标尺上的刻线标记，不足时应加到规定量，但不能超过标尺刻线的上限。
　　检查喷油泵调速器机油平面——如果未达到规定的刻线标记，应添足机油（有的喷油泵调速器上没有标尺，可省去此步骤）。
　　检查水泵的注油点内是否有充足润滑油脂——把柴油机循环水泵上的注油嘴卸下来，观察里面的润滑油脂是否充足，如不足，应用油枪向里面注入充足润滑油脂。
　　检查水箱中的水是否充足——发现水箱中的水不足应及时补充，加入的水应为清洁的淡水，如自来水或清洁的河水。如果直接用地下水，容易在水箱内形成水垢，影响冷却效果而造成故障，因此，地下水软化后方可使用。在北方（环境温度低于零度），必须根据当地的低温度配置适当凝点的防冻液，配方如下：
　　　　　　　　　　乙二醇　　水　　凝点℃

　　乙二醇防冻液　　　　 60　　40　　 -55

　　　　　　　　　　　　55　　45　　 -40

　　　　　　　　　　　　50　　50　　 -32

　　　　　　　　　　　　40　　60　　 -22

　　检查三漏（水、油、气）情况——检查油管、水管接头处的密封面，发现有渗漏，应该立即解决；如果排气管、气缸盖垫片处增压器有松动或漏气现象，也应及时排除。
　　检查蓄电池内酸液的情况——蓄电池内电解液的液面一般应高出极板顶面10～15mm，发现不正常时应加入比重为1.400g/cm³的稀硫酸或蒸馏水进行调整，使其比重达到1.280±0.005（30℃）。切忌加注河水、井水和浓硫酸。
　　检查柴油机各附件的安装情况——包括各附件安装的稳固程度，地脚螺钉及与工作机械相联接的牢固性。
　　检查喷油泵传动连接盘——检查连接螺钉是否松动，如果松动，应重新校正喷油提前角，并拧紧连接螺钉。

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 ~ 15mm, was found to be abnormal 1.400g/cm ³ accounted for by adding the sulfuric acid or distilled water to adjust to the proportion reached 1.280 ± 0.005 (30 ℃). Must not add water, well water and concentrated sulfuric acid.
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.
