Injector 1, functions, requirements and type of function: the high pressure fuel pump injector diesel engineering machinery supplied with engine manufacturers, to a certain pressure, was mist sprayed into the combustion chamber. Requirements: ① ② spray evenly with a certain injection pressure and a range of construction machinery engine, and suitable injection cone angle ③ off the oil quickly, no drip phenomenon injector of the type currently used in jet injector is closed oil, with a hole injectors and injector pintle two kinds. Small parts may be used with or without a pump spray booth curtain spray booth, the former has advanced performance, the latter economical, convenient and practical. Due to heavy construction machinery and parts machine, heat capacity, and therefore construction machinery engine company, its anti-rust coating drying, the general uniform baking hot air convection drying method. Heat can be adapted to local conditions, the choice of steam, electricity, light diesel oil, natural gas and liquefied petroleum gas. Construction equipment provided by the Weifang Huadong Engine Co., Ltd. Weifang engine manufacturers _ _ East China Construction Machinery engine. Weifang Huadong Engine Co., Ltd.
