This part identical with ISO 6626. 1989 "Piston Ring hold spiral spring oil ring" (in English). This section is equivalent translation ISO 6626. 1989 (in English). For ease of use, this section made the following editorial changes. --- "This International Standard" by "this section"; --- Remove the foreword and introduction of international standards. This part of ISO 6626. 1989 and other international standards adopted, where the country has been adopted as a standard by our standards instead of the corresponding International standards; our country has not been adopted as a standard, still direct use of international standards. This part is GB/T 1149.7-1994 "Piston Ring hold spiral spring oil ring," the amendment of this section and GB/T 1149.7-1994 The main difference is. --- GB/T 1149.7-1994 is equivalent to ISO 6626. 1989, and the Department is divided into identical with ISO 6626. 1989. Since the implementation of this section instead of GB/T 1149.7-1994 "Piston Ring hold spiral spring oil ring." This part is proposed by China Machinery Industry Federation. This part of the internal combustion engine by the National Standardization Technical Committee (SAC/TC177) centralized. This section was drafted by. Shanghai Internal Combustion Engine Research Institute, Yizheng Piston Ring Co., Ltd., Anqing Dili Bo Bo Geci Piston Ring Co., Ltd., Fu East Machinery Co., Ltd. was built. The main drafters of this section. Su Qing Hua, Chen Aiguo, Wang Xing, Jibin Jie, Zhong Junjie. This part of the standard replaces the previous editions are. --- GB 1149-1982, GB/T 1149.7-1994.

1 Scope

This section GB/T 1149 specifies the piston ring model DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG and SSF-L Coil springs support the basic dimensional characteristics of the oil ring. Spiral spring support ring cast iron oil ring body recommended levels prescribed for the ISO 6621-3 material 10, there are special requirements can choose level Do 20 to 50 for the material. Oil ring support surface and the corresponding spring groove design, according to the manufacturer's recommendation, use an ordinary type or chrome type. Spiral stays reed cut oil ring to the elastic force can be varied over a wide range, the detailed description and recommended value, see Chapter 6. Spiral spring stays high oil ring ring conventional range of 3mm ~ 8mm, 0.5mm or 1.0mm spacing by increments. Table 15 to Table 20 Regulation Given the currently used British Central High 4.75mm (3/16 ") spiral spring support oil ring size. This section applies to a diameter less than or equal to 200mm cylinder reciprocating internal combustion engine oil ring spiral spring stays. Getting off work in similar conditions The screw compressor for stays spring ring can also refer to the use of oil.
