5. Requirements 要求
Paragraph 5.2, Addition/Clarification 增加/澄清
Vendor’s offering shall be a size and design which has a successful record of proven field rvice at operating conditions similar to tho specified (prototypes are not acceptable). An installation list shall be submitted upon request.
供货商报价中的规格和设计应具有在规定操作条件下现场成功应用的验证记录（不接受样机）。如果有要求，应提交业绩表。
6. Basic Design 基础设计
6.1 General 概要
Paragraph 6.1.24, Clarification澄清
The compressor shall be capable of continuous operation at all partial load steps. (0% load step is for short term startup only).
压缩机应能在部分加载过程中连续操作（0% 加载仅供短期启动）
Compressor vendor shall provide PLC, and PLC shall include control logic to ensure unloading of both partially and fully unloaded cylinders follows best practices established below:
压缩机供应商应提供PLC，PLC应该包括控制逻辑单元来确保气缸部分或完全卸载时采用如下最佳方案表
情况 | 狂欢节的由来最佳方案 |
部分卸载 | 周期性，短暂的载入气缸头空载来阻止润滑油积聚对机器造成的损害 |
完全卸载 | 仅对多级气缸并联操作状况下，加载卸载定期切换来阻止热量或润滑油积聚对机器的损害 |
| |
Manufacturer to state frequency and duration of required loading to achieve above objectives in proposal.
未达到以上目标，制造商需提出加载频率和持续时间
