发动机水泵的使用方法以及维护措施

译文：
在使用与维护发动机水泵时必须注意以下几点： 正确安装安装时，齿轮传动式水泵的齿轮应和传动齿轮紧密结合，皮带传动式水泵应保证水泵轴和皮带轮的同轴度在规定的范围内，防止发动机因增加转速或负荷而导致水泵产生晃动，加剧磨损。 正确调整皮带的松紧度风扇皮带不可调得过紧，否则会加大水泵轴承的负荷。如果是两根以上的皮带传动，要保证几根皮带的新旧、长短、松紧度相一致，防止因各根皮带拉力不均匀，使水泵受力不均衡而过早损坏。 及时加注润滑油要根据说明书中的规定，及时对水泵轴承加注润滑油，加注润滑油的数量不可太多或太少，以防轴承过早损坏。 不可堵塞溢水孔有的水泵轴处有溢水孔，通过溢水孔可观察水泵是否漏水。如果溢水孔受堵，水泵泄漏的水会进人轴承内而影响润滑，引起轴承过早损坏。 拆装时不得猛打硬敲检修水泵时，拆卸皮带轮和水泵内轴承等主要部件应用专用工具。安装时若猛打硬敲，易造成水泵轴承弯曲变形、水泵轴轴端螺纹滑扣或损伤。另因叶轮和泵轴配合较紧，除非必要，一般不拆卸。 及时清除水泵内的水垢水泵内水垢积聚过多，会使水泵泵水能力减弱，同时水垢还会腐蚀水泵内各部件，易使水泵过早损坏。

In the use and maintenance of the engine water pump must note the following points: Installed correctly installed, the gear drive pump gear and transmission gear should be closely integrated, belt drive water pump water pump shaft and the pulley should ensure the concentricity within the prescribed limits, to prevent the engine speed orHorizontal single-stage single suction centrifugal. load by increasing the pump produces a result of shaking aggravated the wear and tear. The correct adjustment of belt tightness adjustable fan belt is not too tight, otherwise it will increase the water pump bearing load. If two or more of the belt drive, to ensure that new and old Jigen belt length, tightness consistent belt tension to prevent uneven due to the roots, so that a balanced and premature failure of pumps Shouli Bu. The timely filling of the oil according to the instructions provide for the timely filling of the pumpSplit case single-stage double suction centrifugal bearing lubricating oil, lubricating oil filling quantity can not be too much or too little to prevent premature bearing damage. Some pumps can not plug the overflow hole axis Department has overflow hole, through the overflow hole is leaking water pumps can be observed. If the overflow hole by blocking the water pump leak into the bearing will be affected by lubrication, causing premature bearing damage. He shall not play the hard-knock disassembly repair water pumps, the demolition of pulley and water Single-stage single suction in-line centrifugal pumps pump bearings and other major components within the application-specific tools. If the blow to a hard knock during installation is easy to cause deformation pump bearings, water pump shaft threaded shaft sliding buckle or injury. Another result of the impeller and shaft with a tight, unless absolutely necessary, generally not demolished. Clear water pump within the time scale within the scale accumulation of too much water pumps, water pumps will pump water weakened ability to pump at the same time scale but also within the corrosion of parts, easy to make premature pump damage.
