QJ气体继电器采购为什么要确认口径和接点？

• 适合采购QJGas Relay、瓦斯继电器和油浸式变压器保护附件的客户。
• 询价前建议确认QJ型号、口径、安装方向、信号接点和旧件照片。
• 气体继电器属于保护附件，不建议只凭外观或管路大小采购。

QJ气体继电器采购常用于油浸式变压器维护、备件更换和项目配套。它与油管接口、安装方向和信号接点有关，询价前需要确认口径和接点要求。英诺通达可供应的相关型号包括 QJ9-25、QJ3-80/50、QJ2-80/50、QJ1-80/50等相关气体继电器产品。

QJ气体继电器不同型号和口径不能简单互换。采购时请提供完整型号、口径标识和安装方向，旧件替换还要看接口和管路位置。

如果旧件铭牌清楚，请拍铭牌、整体、法兰接口、接线盒和油管连接位置。若铭牌不清楚，请提供管路尺寸和设备图纸作为辅助资料。

QJ气体继电器口径接点项目配套和备件区别

Project specifications focus more on drawings, order quantities, technical documentation, and delivery schedules, while spare part replacements focus more on old models, wiring, installation dimensions, and on-site compatibility. When requesting a quote, clearly state the intended use so that suppliers can more quickly identify the key points in the documentation.

If you need both spare parts and project products, we recommend listing the quantities, delivery dates, and documentation requirements separately. We will confirm these based on their specific uses and will not apply a single model or set of specifications to all procurement requests.

Confirmation of Information and Pricing

To ensure that the quote more closely matches your actual procurement needs, we recommend that you clearly specify the product name, full model number, quantity, intended location of use, whether the product is a replacement for an existing item, whether English documentation is required, and your expected delivery date when making initial contact. If the product is to be used as part of a project, you may also provide drawings, technical specifications, and packaging and shipping requirements.

Innotongda will provide documentation and quotations based on the models, configurations, and technical requirements confirmed by both parties. This will reduce the need for repeated verification and minimize the risk of purchasing incompatible products.

Procurement Contacts and Responses to Inquiries

If the buyer already has photos of the used parts, they can simply send the images and quantities; if this is for a new project, they can first send the drawings, technical specifications, or a product list. We will first confirm the product details and then respond with the relevant materials, pricing, and any additional information required.
