目前,油锯供油系都采用了泵膜式化油器,并且已采用化油器通过单向阀直接与曲轴箱相通的结构型式。这使油锯的工作性能及燃油的消耗都有所改善。但是,某些油锯的化油器在结构上或某些零件所用的材料上都存在一些问题。这些问题直接影响化油器的工作性能、油锯的锯切效率、耗油量及机械寿命。下面仅就我们通过油锯使用试验,对一些主要部件——化油器、单向进气阀的分析意见提供参考。一、化油器1、温度对化油器的影响。油锯发动机
At present, the fuel supply system of the chain saw has adopted a membrane pump carburetor, and carburetor has adopted the one-way valve directly connected with the crankcase structure. This improves the workability and fuel consumption of the chain saw. However, some chainsaw carburetors have some problems with the structure or with the materials used for certain parts. These issues have a direct impact on the performance of the carburetor, sawing efficiency, fuel consumption and mechanical life. The following only through our use of chain saw test, some of the major components - carburetor, one-way intake valve analysis advice. First, the carburetor 1, the temperature of the carburetor.
