The first direct measurement with micrometer piston skirt and the outside diameter Do micrometer stop screw to the locking plate position, and then dial indicator card installed and well well inserted under the initial installation of the amount of cards, directly into the cylinder corresponding cylinder kit, adjust the volume of the cylinder rod out in table inserted length, so that small hands dial indicator cell has about 1 volume of pre-press and lock locking rod inserted mother, at the same time, large dial indicator dial to adjust zero, the last cylinder to adjust the volume of good form under test card inserted rods and do at Anvil micrometer and measured the rod between the big hands dial indicator at this time than the "zero" high value is the piston and cylinder liner with the space.

3先直接用千分尺测量活塞裙部的外径并将干分尺止动螺钉扳转到锁紧位置，再将卡装好百分表和初步安装好插杆的量缸表直接卡入对应气缸套内，调整量缸表插杆的伸出长度，使百分表的小表针有1格左右的预压量并锁紧插杆锁母，同时将百分表的大表盘调整到零，最后将调整好的量缸表的测杆和插杆卡在干分尺的砧座和测杆之间，此时百分表大表针比&零&高的数值即为活塞和气缸套的配合间隙。

The first direct measurement with micrometer diameter piston skirt, and then dial indicator card installed and the initial installation of the amount of good cylinder rod inserted card table micrometer mounted on the anvil between the seat and the measuring bar, adjust the volume of cylinder table Interpolation of the extended length of rod, when the dial indicator has small hands around 1.5-2 cell volume preloading lock locking rod inserted mother, and a large dial indicator to zero adjust the final stretch to the volume of cylinder table into the Cylinder Sleeve, large dial indicator hands than "zero" low value (considering the small hands reading) is the piston and cylinder liner with the space.

In diesel engine cylinder, the piston part of the cycle in the compressed gases, and in another part of the work cycle of the combustion gas mixture within the cylinder so the piston top surface expansion high pressure (about 116 ~ 120Kgf/cm2)°under high temperature (about 569°C) gas role, and the pressure through the piston pin, connecting rod to the crankshaft.

在柴油机气缸内，活塞在一部分工作循环压缩气体，而在另一部分工作循环气缸内混合气体燃烧膨胀使活塞顶面承受高温（约569°C）高压（约116～120Kgf/cm2）气体的作用，并把压力通过活塞销、连杆传给曲轴。

The function of air filter is to filter the dust and impurity from the air entering into engine, to ensure the cleanliness of the air inside of cylinder; to decrease the worn between cylinder and piston, piston bodies, and valve components.

空气滤清器的作用是把进入发动机的环境空气中的灰尘和杂质滤掉，从而保证气缸内的空气清洁，减少气缸与活塞之间，活塞组本身，以及气门组零件的磨损。

Even slight traces of grit or dust left on the cylinder walls may cause rapid ring and wall wear and early engine failure.

残留在气缸壁上的砂砾或尘埃所造成的划痕，均能引起活塞环和气缸壁的迅速磨损以及发动机的早期损坏。

Even slight trace s of grit or dust left on the cylinder walls may cause rapid ring and wall wear and early engine failure.

残留在气缸壁上的砂砾或尘埃所造成的划痕，均能引起活塞环和气缸壁的迅速磨损以及发动机的早期损坏。

In the reciprocating pump, the suction valve and exhaust valve is a very important component and is vulnerable parts of their work a direct impact on the limit pressure reciprocating pump, extraction rate, power consumption, as well as the reliability of operation.

气缸摘要：在往复泵中旋转气缸，吸气阀和排气阀是非常重要的部件且是易损部件，它们工作的好坏直接影响往复泵的极限压力、抽气速率、功率消耗以及运行的可靠性。

The first to use PRO / E software components establishment of the body (body, cylinder head, cylinder pad, cylinder liner, the main bearing caps, Flywheel carcasses, gear Connection Board Room, Shell pump, oil pan, about mounting frame, rear axle oil blocks, etc.) 3D solid model; Then use Hypermesh software division finite element mesh to ensure a good grid quality, and better coordination of the grid between quantity and accuracy of contradictions; Finally using ANSYS software components of a body finite element analysis.

首先利用PRO/E软件建立机体组件（机体、气缸盖、气缸垫、气缸套、主轴承盖、飞轮壳、齿轮室连接板、水泵壳体、油底壳、左右悬置支架、后轴油封盖等）的三维实体模型；然后利用Hypermesh软件划分有限元网格，保证了良好的网格质量，较好地协调了网格数量和计算精度之间的矛盾；最后利用ANSYS软件对机体组件进行了有限元分析。

Check the worn situations of piston ring, cylinder bore, connection rod small end bushing and connection rod bore; replace them as necessary except for cylinder bore can be bored or add repair using cylinder liner

4.4.3检查活塞环、气缸孔、连杆小头衬套及连杆轴孔的磨损情况，必要时除气缸孔可镗孔或加修理用缸套外，其余则可更换

A, Pneumatic: air cleaner, air pipe, the direction valve, cylinder, vacuum equipment, pneumatic instrumentation, pneumatic connectors, cylinder seals.

a、气动：空气洁净、空气管道、方向阀、气缸、真空设备、气动仪表、气动接头、气缸密封件。
