Start from simple maintenance items 先从基础维护项检查
When vacuum performance drops, check oil condition, inlet filter, exhaust filter and visible leakage before replacing the whole pump. 当真空性能下降时，应先检查真空泵油、进气过滤、排气过滤和明显漏气，再判断是否整泵替换。
Regular maintenance can reduce downtime for distributors, service companies and factory maintenance teams. 定期维护可以帮助经销商、维修服务商和工厂维修团队降低停机时间。
Common spare parts 常见备件
Common parts include vacuum pump oil, oil mist separator, inlet filter, seals, vanes and repair kits. 常见备件包括真空泵油、油雾分离器、进气过滤器、密封件、叶片和维修包。
For quotation, send pump model, part photos, quantity and whether the parts are for routine stock or urgent repair. 询价时请发送泵型号、备件照片、数量，以及是日常备货还是紧急维修。
Support for repeat service 支持复购和维修服务
For dealers and service companies, stable parts supply is often as important as the pump itself. 对于经销商和维修服务商，稳定备件供应通常和整泵一样重要。
A trial order can start from one pump or selected spare parts before larger repeat purchasing. 合作可以从一台试单或部分备件开始，再逐步复购。
