It is subject to change without notice and shall not be referred to as a European Standard.D ra f tf or vo t eEN 60335-2-79:2004/FprAC:2008 – 2 –ForewordIn the light of the necessity to adapt EN 60335-2-79 with regard to the requirements of the Machinery Directive 2006/42/EC, the present draft was prepared by CENELEC TC61/WG6/J in co-operation with the MD Consultant, taking also into account the results of CENELEC TC61/WG6 work on EN 60335-1. The approach to amend EN 60335-2-79:2004 aiming toward listing the standard under the MD was discussed and approved during the Kista meeting of CENELEC TC61 in June 2008 (see CLC/TC 61/SEC/1649), when it was decided to submit a draft for an amendment to the Unique Acceptance Procedure.In this document, the text of the draft amendment FprAC is written in blue. The National Committees are invited to vote on this blue text only.If voted positively, the present document as a whole will be approved as a new edition of EN 60335-2-79 with the common modifications identified by a vertical line in the left margin.The following dates are proposed:–latest date by which the existence of the amendment has to be announced at national level(doa)dor + 3 months –latest date by which the amendment has to be implemented at national level by publication of an identical national standard or by endorsement(dop)2009-12-29 (same as dow)–latest date by which the national standards conflicting with the EN have to be withdrawn(dow)2009-12-29 ** A dow of 2009-12-29 is proposed so as this European Standard applies at the same time as the time of application of the new Machinery Directive.

▲天津市通洁高压泵制造有限公司乃中华人民共和国国家标准GB/T26135-2010《高压清洗机》制定单位。

▲箱体为精密树脂砂铸造，散热性能好、强度高；箱体所用涂料为环氧树脂垂纹漆，外形美观。

▲曲轴采用高强度合金钢锻打制造,增强了在交变载荷工作条件下抗冲击的能力,保证高压泵运行平稳，克服了因受力不均而引起的磨损．表面光洁度高，连续运转性能优越，摩擦系数大大降低。

所用重载轴承全部为国产名牌，内置减速轴带有一套人字型斜齿轮，传动的润滑系统采用飞溅滑润方式，润滑性能可靠
▲动力端曲轴与连杆采用轴瓦结构，摩擦系数小、润滑性好、传动平稳。

动力端升温低，更适于长时间作业。

▲锌基合金材料作连杆小头衬套，使连杆小头的承载能力在不放大结构尺寸的情况下，大幅度提高了泵的工作能力。

▲40Cr镀Ni泵头，能抵抗交变应力，因此可防止破裂
▲阀组采用了组合式轴向对称布置，液力体积小，密封面减小，可靠性增加，有效地克服因疲劳破坏而引起的缸体破裂，提高了泵体的使用寿命
▲可以多种压力、流量相互变换，大大提高了设备的应用广泛性，降低了设备的投入成本。

▲进排液阀组采用板形阀，整体式泵体，使液力端的结构进一步简化，体积缩小，密封面增大，可靠性增加
▲所用填料密封全部为德国原装进口。

▲柱塞采用了合金钢镀Ｎi60处理，大大提高了柱塞的耐磨性，延长了泵的使用寿命。

▲填料函，进排液阀采用Cr钢制造，在保证强度的基础上有效的提高了其抗腐蚀性能。

▲整机移动式底盘转向系统采用大型滚珠轴承式结构，转向移动更加省力。
