Description

单缸柴油机电控油路自动排气装置  Single cylinder diesel electric control oil passage automatic exhaust device
技术领域  Technical field
本发明涉及一种单缸柴油机电控油路自动排气装置， 具体地说是用于单 缸柴油机电控油路中进行排除空气， 属于机械结构部件技术领域。  The invention relates to a single-cylinder diesel electric control oil passage automatic exhausting device, in particular to a single-cylinder diesel electric control oil passage for removing air, belonging to the technical field of mechanical structural components.
背景技术  Background technique
本发明作出以前， 在已有技术中， 一般单缸柴油机电控油路中， 如果有 空气进入， 会造成起动困难， 起动后运行不平稳。 对于全封闭的机组而言， 若再人工排气， 那更是麻烦。  Before the present invention was made, in the prior art, in the general single-cylinder diesel electromechanical oil control circuit, if air enters, it will cause difficulty in starting, and the operation after starting is not stable. For a fully enclosed unit, it is even more troublesome if it is manually vented.
发明内容  Summary of the invention
本发明的目的在于克服上述不足之处， 从而提供一种单缸柴油机起动后 如果有空气进入， 不需人工排气， 运行平稳， 使用方便， 成本低的单缸柴油 机电控油路自动排气装置。  The object of the present invention is to overcome the above-mentioned deficiencies, thereby providing a single-cylinder diesel engine automatic air exhausting device for single-cylinder diesel engine electric control oil passage if there is air entering after starting, no manual exhausting is required, stable operation, convenient use and low cost .
本发明的主要解决方案是这样实现的 - 本发明主要采用三通管接头进油管 1用油管 4与油箱 5连接； 回油管 2 用另一根油管 6与油箱 5顶部连接， 出油管 3与进油管 1、 回油管 2连接为 一体。  The main solution of the present invention is realized in this way - the present invention mainly uses a three-way pipe joint inlet pipe 1 with a fuel pipe 4 connected to the oil tank 5; the oil return pipe 2 is connected to the top of the oil tank 5 by another oil pipe 6, and the oil discharge pipe 3 and the inlet The oil pipe 1 and the oil return pipe 2 are integrally connected.
本发明与已有技术相比具有以下优点：  The present invention has the following advantages over the prior art:
本发明结构简单、 紧凑， 合理； 当单缸柴油机第一次起动后， 再次起动 时， 油路中空气及小部分燃油通过回油管中小孔经过回油管回到油箱顶部排 除了空气， 而无法进入喷油泵内部， 达到自动排气目的； 无需人工排气， 运 行平稳， 成本低， 使用方便。  The invention has the advantages of simple structure, compactness and reasonableness; when the single-cylinder diesel engine is started again, when the vehicle is restarted, the air in the oil passage and a small part of the fuel pass through the small hole in the return oil pipe and return to the top of the fuel tank through the return oil pipe to eliminate the air, and cannot Enter the inside of the fuel injection pump to achieve automatic exhaust; no manual exhaust, stable operation, low cost and easy to use.
