Repair technology Caterpillar CAT diesel engine lubrication system

卡特彼勒CAT柴油发动机润滑系统有一个三齿轮的油泵，由前端齿轮链驱动，油从油槽经过吸入漏斗(１６)和弯管(１５)被油泵吸入，吸入漏斗有一螺旋以清洗滑油。

Caterpillar CAT diesel engine lubricating system with oil pump with a three gear, driven by the front gear chain, oil from the oil tank by suction hopper (16) and (15) by the oil pump suction pipe, suction hopper with a spiral cleaning oil.

油泵将油压出，通过冷却器(11)和机油过滤器到达机体的油沟(1)和(2)。润滑油在送往过滤前被隔片和管式冷却器冷却降低温度。

Pumping oil out, through the cooler (11) and the oil filter to the oil groove body (1) and (2). Lubricating oil in to a filter before being spacer and pipe cooler cooling temperature decrease.

如果滑油冷却器堵塞式滑油粘度变大(冷天起动)，使压力差(冷却器进口到出口)增加到180±20千巴(26±3磅／吋²)旁通伐(12)动作使滑油直接流到过滤器。

If the oil cooler blocking oil viscosity increases (cold start), so that the pressure difference (cooler inlet to outlet) increased to 180 ± 20000 bar (26 ± 3 pounds / Cun) bypass cutting (12) moves to make the oil flow directly into the filter.

筒形过滤器装在卡特彼勒柴油机前的过滤壳里(17)，一个单级旁通伐装在过滤器壳体里。

The cylindrical filter mounted on the filter shell Caterpillar diesel engine in front of the (17), a single stage bypass of installed in the filter housing.

从过滤器来的清净油通过弯管(9)进入机体。一部分滑油进入左凸轮轴油沟(2)，其余的进入主油沟(1)。

From pure oil filter to the elbow (9) into the body. A part of oil into the left cam shaft oil groove (2), the rest into the main oil groove (1).

卡特彼勒CAT柴油发动机凸轮轴油沟通过钻孔与每个凸轮轴轴承相接，滑油进入每个滑油轮轮颈，通过气缸头和摇臂箱到达摇臂轴。钻孔使气门升杆机构油孔连通到摇臂轴油孔，气门升杆每运动到行程顶点就得到润滑。

Caterpillar CAT diesel engine camshaft oil groove through the hole and is connected with each camshaft bearings, lubricating oil into each slide tanker round neck, reach the rocker shaft through the cylinder head and the rocker box. Drilling the valve lift rod mechanism of oil hole is communicated to the rocker shaft oil hole, the valve lift rod every movement to limit vertex get lubrication.

主油沟(1)通过钻孔与主轴承相接，曲轴中钻孔与主轴承油孔相接将油供到连杆轴承，从主油沟尾部来的滑油进入右边凸轮轴沟(5)的尾部。

The main oil groove (1) is connected with the main bearing crankshaft through drilling, drilling and main bearing oil hole is connected to the connecting rod bearings will supply of oil, lubricating oil from the main oil groove tail into the right cam shaft groove (5) tail.

程序伐(7和8)使滑油从主油沟(1)进入活塞冷却喷油沟(3和4)，程序伐在140千巴(20磅/吋²)打开，直到主油沟有压力后，程序伐才让滑油进入活塞冷却油沟，这样就减少了卡特彼勒柴油机起动时建立起压力所必要的时间，同时也有助于空转时保持压力。

Cheng Xufa (7 and 8) so that the oil from the main oil groove (1) into the piston cooling oil groove (3 and 4), the program of up to 140000 bar (20 lbs / inch ²) opened, there is pressure until the main oil channel, program of that oil into the piston cooling oil groove, thus reducing the Caterpillar diesel. Establish the necessary pressure time, also conduce to at the same time idling maintain pressure.

在每个活塞底下有一个活塞冷却喷射器，每一冷却喷射器有两条通道。一条在活塞底部的通道上，这条通道将油通到活塞环带后的一条支管，一狭缝位于活塞销孔边部，销孔又与环带后的支管相接。另外一条通道在活塞中心方向上，这样有助于冷却活塞和润滑活塞销。

In each piston under a piston cooling jets, each cooling injector with two channels. A piston in the bottom of the channel, the channel will be a branch oil to the piston ring after, a slit in the piston pin hole edge, pin hole and ring after the branch. Another passage in the center of the piston direction, so that helps the piston cooling and lubricating the piston pin.

滑油管线(6)将油送到增压器，增压器排放油线(21和22)与卡特彼勒柴油机每边上的飞轮壳体相接。

Oil pipeline (6) the oil to the turbocharger, turbo emission line (21 and 22) and Caterpillar diesel engine flywheel shell on each side.

滑油通过前和后壳体和缸体表面的钻孔通道送往前和后齿轮组，这些钻孔通道与凸轮轴油沟(2和5)相接。

Lubricating oil through the front and rear shell and cylinder surface drilling channel sent forward and rear gear group, the drilling channel and the cam shaft oil groove (2 and 5).
