4大连龙泵RFD20(包括RFD83、RFD204等)调速器4.1配套用途RFD20两极全程调速器与A(AD)型泵配套。主要用在4、6缸100-113系列柴油机上,能满足拖拉机、汽车、工程机械和特种工程车辆等多种用途的需要。RFD20调速器结构、工作和上述介绍的RFD(K)调速器基本相同。现仅介绍拆装部分的不同点和调试部分。4.2拆卸装配装配应注意以下几点。(1)凸轮轴轴向间隙为0.04~0.08 mm。(2)齿杆在任何工况下都应滑动自如,有条件用弹簧秤检查齿杆动态滑动阻力,4、6缸油泵转速为1 000
4 Dalian Long pump RFD20 (including RFD83, RFD204, etc.) governor 4.1 matching purposes RFD20 bipolar speed governor and A (AD) pump supporting. Mainly used in 4,6 cylinder 100-113 series diesel engine to meet the needs of tractors, automobiles, construction machinery and special engineering vehicles and other purposes. The structure of the RFD20 governor is basically the same as the RFD (K) governor described above. Now only introduce the disassembly part of the differences and debugging part. 4.2 disassembly assembly should pay attention to the following points. (1) Camshaft axial clearance of 0.04 ~ 0.08 mm. (2) Shank in any condition should be free to slide, the conditions for the use of spring-loaded rack check the dynamic sliding resistance, 4,6-cylinder pump speed of 1 000
