  Preliminary assessment by phone or WeChat (same-day reply): Tell us the equipment name, the fault symptoms, when and how often it occurs, and what has already been tried. If convenient, send photos of the fault location and the nameplate parameters by WeChat, and we will make a remote preliminary assessment on that basis - first a directional opinion and a recommendation on whether an immediate site visit is needed. This step is free.

  Scheduling and arrival: Nanchong city, its Shunqing, Gaoping and Jialing districts, and the six counties of Langzhong, Nanbu, Yingshan, Yilong, Peng'an and Xichong are dispatched same-day by our resident Yilong team, with arrival typically in 1-2 hours; Chengdu, Chongqing and other prefecture-level cities in Sichuan are reached the next day; for Yunnan and Guizhou areas we confirm the schedule by phone first, usually arriving within 48 hours. Sudden stoppages and deadline-critical emergencies trigger our emergency mechanism with priority dispatch.

  Site survey and data collection: We settle in and measure the data - current, temperature, vibration, insulation, clearances, alignment, missing nothing that should be measured; at the same time we check the ledger, review downtime records and question the operating crew. Facts first, judgements second - no snap calls from experience alone.

  Issuing a written plan and quote: It states clearly the fault symptoms, test data, root-cause analysis, treatment measures, schedule, cost and acceptance criteria. Where a repair, retrofit or replace choice is involved, an economic comparison of the three options with payback periods is attached. Work starts only after your confirmation, with no mid-job price increases. For emergencies we can repair first to restore production and complete the paperwork afterwards, per the plan.

  Execution with records at key steps: The downtime window is aligned with the production plan, and spare parts and tools are staged on site in advance. Overhaul work follows power-off, tagging, lockout and energy-release confirmation; removed and installed parts are sorted and marked; clearance, torque, alignment and insulation data are recorded item by item and signed by both parties - no record, no next step.
• 6
  Double trial runs and acceptance: The no-load run checks for abnormal noise, temperature rise and vibration; the loaded run checks output curves and cycle times; accuracy is re-measured against factory standards and process requirements, verified with a standard test piece where necessary. Data speaks - no verbal assurances.
• 7
  Filing, handover and training: Drawings, inspection sheets, baseline data and lubrication cards are filed and handed over; operating and maintenance personnel are briefed on what was treated this time, what to watch in daily operation, and which signs mean a repair request is due. Delivery counts only when the operators pass their assessment.
• 8
  Three months of follow-up: Fault-repair services are followed up and verified for three months to confirm no recurrence; if the same root cause recurs within the tracking period, it is handled under the original plan at no extra charge. Operating data feeds back into the maintenance strategy, and the plan is revised with the equipment's condition.
