NSK轴承SKF轴承，价格非常昂贵。实践等温淬火后NSK轴承，火灾发生后的平均寿命比淬火和可靠性显着改善。该工艺被广泛应用于铁路轴承，轧机轴承，NSK轴承使用的特殊条件。这个过程相比，寿命延长，工艺简单，低利率的措施。近年来，中国已经开发出一个新的特殊钢GCr18Mo钢贝氏体淬火，以促进贝氏体淬火NSK轴承上的应用程序的很大一部分。鉴于过程中的诸多优势，我们建议使用条件苛刻（大的冲击负荷，润滑不良等），或需要NSK进口轴承的高可靠性，促进大型夹杂物和碳化物多用更多样化的环境NSK轴承，NSK轴承的要求也越来越苛刻。

Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the buried depth of 1-35kv cable is not less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature is not lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. 6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be cleaned. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and accidents such as burning sheath. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic re for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent erosion of water and other corrosive materials, so as to prevent breakdown due to the aging of the insulation layer caused by water trees. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be done by the installation personnel or full-time technical personnel familiar with the performance of wire and cable. If there are still unclear matters, please consult the relevant technical department or the technical department of our factory.

　　主要用於管道敷设。在缆芯中和屏蔽层的内外表面用石油膏填充和浇注处理，以防止水分侵入。在一30~C一60~C的环境条件下，电缆的机械和电气性能保持不变。结构：导线：退火裸铜线，铜线直径为0．32，0．40，0．50，0．60，0．70，0．80，0．90(mm)。

厨房五金按设置可分为普通和特殊两大类，前者包括合页、铰链、滑轨等，后者包括浴室五金和厨房挂件等。其中铰链、滑轨、合页和锁具在生活中使用频率更高，因而显得更为重要。part1保养1.为防止冻坏，家中水管、水表、水龙头用水设施，可以使用棉麻织物、旧棉衣、棉絮等保温材料加厚包紧。夜晚应关闭厨房、厕所对外以及所有背阴房间的窗户，保证室内的温度在℃以上。对于室内温度低于℃的房间，要关闭室内水表阀门，打开水龙头，放尽水管中剩水。在严寒天气(-5℃以下)，在晚间用水后稍稍拧开水龙头，将水龙头保持很小的滴流状态，保证水管内自来水流动，防止夜间被冻住。对于已冻结的水管，宜先拧开水龙头，用热毛巾包裹水龙头，然后浇温水，用温水沿水龙头慢慢向水管浇洒，使水管解冻。若浇至水表处仍不见有水流出，则说明水表也冻住了，此时在水表上包上热毛巾用温水(不高于3℃)浇洒，使水表解冻，切忌用火烘烤。part2清洁只要用清水漂洗水龙头即可，再用软棉布抹干水龙头。
