1、ANSI/ASAE S418.1 OCT2010 (R2014) Dimensions for Cylindrical Hydraulic Couplers for Lawn and Garden Tractors American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering applicable t
2、o agricultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead equipment, s
3、tructures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only.
4、Their use by anyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordinances, laws and regulations. Prospec
5、tive users are responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the revision approval date. Newly developed
6、 Standards, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the requirements
7、for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a
8、 simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require th
9、at action be taken periodically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

13、ers, Hydraulic, Lawn, Tractors 1 Purpose 1.1 The purpose of this Standard is to establish interface dimensions of cylindrical hydraulic couplers frequently used by the equipment industry to connect hydraulic remote cylinders and other hydraulic devices to lawn and garden tractors. 1.2 The purpose of
14、 this Standard is also to permit interchangeable use of remote cylinders and other hydraulic devices on different makes of tractors when designed for this use. 2 Scope 2.1 This Standard covers only cylindrical couplers where interchange between makes is recommended. 2.2 This Standard does not preclu
15、de other types of hydraulic couplers used for similar purposes. 3 Coupler Dimensions 3.1 The male half of the coupler is considered part of the cylinder or hydraulic device and shall conform to dimensions given in Table 1. 3.2 The female half of the coupler is considered part of the tractor hydrauli
16、c system and shall accept the male half which conforms to dimensions given in Table 1. 3.3 When a quick release, breakaway, or other special feature is required, it shall be provided as part of the female coupler without interfering with interchangeability of the standard male coupler. 3.4 The trave
17、l of the valve in the male coupler will be limited as shown in Figure 1, and the force required to open the valve when no pressure is in the coupler shall not exceed 44 N (10 lb).

25、 Agricultural and Biological Engineers 4 5 Performance Requirements 5.1 The maximum pressure drop through the male half of the coupler shall not exceed 172.4 kPa (25 psi) at rated flow with mineral oil at a viscosity of 55 Saybolt Universal Seconds minimum. When measuring restriction, the sealing va
26、lve shall be depressed flush with the end of the valve body. 5.2 When the two halves of the coupler are locked together in the operating position, they shall remain locked together, without failure, when subjected to a proof pressure of 200% of the rated pressure. 5.3 The male half of the uncoupled
27、coupler shall withstand a minimum burst pressure of 400% of the rated pressure. 6 Compatibility with Fluids 6.1 For the purposes of this Standard, it should be assumed that SAE 20 mineral oil will be used. 6.2 Couplers and cylinders, or other hydraulic devices, should be made with seals and other materials which are compatible with SAE 20 mineral oils and additives normally used in tractor hydraulic systems.
