例文一CONNECTING CYLINDERS TO FRAME RUN-OUT1. ConnectionIf the compressor reaches the job site with the cylinders still to be connected, they will be in-stalled after the final anchoring of crankcase and crosshead extensions. The complete procedures for connecting the cylinders to the frame and an-choring them to the foundation are given in items and 1・2・=WARNING=For the correct arrangement of the cylin-ders on the frame, refer to the GENERAL ARRANGEMENT drawing of the compressor included in the part DATA SHEETS and SCHEMATICS of this Manual. In case that more cylinders are due to the same stage, refer to the WORKSHOP ASSEMBLING CARD found in the QUALITY DATA BOOK of this compressor・If the cylinders reach the job site already con-nected, no special procedure need to be carried out for vertical cylinders. For horizontal cylinders, start from step a of item 1.2 and after having completed step b, loosen the nuts of the stud bolts fastening the cylinder to the frame. Then go on to steps c and following・When the cylinders are to be connected to frame on the jobsite, after the procedure has been completed, the piston must be connected to the crosshead. Consult the CROSSHEAD paragraph in the FRAME AND CRANKGEAR Section and the PISTONS-PISTON RODS paragraph in the CYLINDER ASSEMBLIES Section. LleVertical cylindersa ・ Thoroughly inspect the mating faces between frame and cylinder, removing any traces of dirt or machining residue (rust, burrs, etc.).b - Grease the surfaces specified in item a. Pre-pare and apply to one of them a gasket, ob-tained from a sheet of thin paper.c - Sling the cylinder. This procedure must be car-ried out very accurately in order to obtain cor-rect positioning of the cylinder in respect to the frame・d - If the cylinder is complete with the piston as-sembly, bring the crosshead to the inner dead centre.e - After having correctly positioned the cylinder in respect to the reference points (punching, dow-els, etc.), insert the base of the cylinder into the spigot on the crosshead extension (or dis-tance piece) being careful to carry out, with the lifting means, small steps to allow the stud bolts and the dowel pins (if any) to smoothly enter their respective holes.-Place the cylinder gently on its seat and pro-ceed to crossover tightening of the bolts. Tighten to the torque value specified in the CYLINDER ASSEMBLING DATA Table. (See PART LISTS part of this Manual)."•Horizontal cylindersIf a completely assembled cylinder is to be in-stalled, it is advisable to carry out the procedure after having disassembled the partition cover. This will avoid no impacts between piston rod and par-tition cover, which are possible in case the lifting and positioning of the cylinder be performed wi-thout the necessary experience or using improper equipment.-Proceed as described in item 1.1. steps a，b： c, d，e.-Approach the cylinder until the mating faces between frame and cylinder are distant from each other by a few tenths of a milunetre.-Screw but not tighten the nuts on the stud bolts joining the cylinder to the frame・a - Place a screw jack under the cylinder, as close as possible to the point in which the support will be connected, keeping in mind that the jack must not interfere in subsequent procedures for the assembly and anchoring of the support.b - Put the jack under stress, being careful not t汽缸组装手册组装汽缸部分在空气压缩机运抵施工场地时若未组装到压缩机上，则应在锚定曲 轴箱和十字结联轴节部分之前予以安装。
