国产4125.4115系别的发动机及其用于的拖拉机、发电机组、绞盘机、等动力机械,由于它们的用途不同,所以,它们的额定功率不同,额定转速也不同。但是,它们几乎都装有A_4 CB 8.5×10型四柱塞带全制式离心调速器的高压油泵。鉴于目前各单位使用上述系别的不同功率,不同转速的各种动力机械越来越多,但是库存的备用高压油泵调速器,也不可能样样具备,往往出现有那种无这种,接应不上,据此情况,就需对A_4 CB 8.5×10型四柱塞带全制式离心调速器进行改用,满足生产的需要。这种高压油泵,以配东方红-54型拖拉机为例,在制造厂出厂后,它的额定转速是1,300转/分(凸轮轴转速650转/分),若要把
Domestic 4125.4115 Department of other engines and tractors, generating units, winches, and other power machinery, because of their different uses, therefore, their rated power is different, the rated speed is also different. However, almost all of them are equipped with A_4 CB 8.5 × 10 type four-piston high-pressure pump with a full-size centrifugal governor. In view of the current use of the above units of different power, different speed of a variety of power machinery more and more, but the inventory of spare high-pressure pump governor, it is impossible to have everything, often there is no such kind of, Do not respond, according to this situation, you need to A_4 CB 8.5 × 10 -type four-plunger with full centrifugal converter governor to meet the production needs. This type of high-pressure oil pump, with the Dongfanghong-54 tractor as an example, has a nominal speed of 1,300 rpm (camshaft speed of 650 rpm) after it leaves the factory.
