Jiangsu Nanyuan HydraulicA factory result should be carried into site acceptance only with its conditions and configuration attached. Transport, installation and connections to site equipment can introduce questions that a factory demonstration did not address. Identify what remains applicable, what changed and what qualified reviewers require before deciding which evidence must be repeated.
Nanyuan’s Y81 series catalog entry requests a current drawing and data sheet for a configuration-specific discussion. It does not define a universal factory or site acceptance standard. The map below is a buyer coordination tool; the agreed project documents and responsible technical parties determine the actual acceptance scope.
Preserve what the factory evidence actually covered
For each factory observation, record the machine reference, configuration revision, material lot, supporting equipment and method reference. Link the result to its original record rather than copying only a favorable number into a summary. Distinguish an observed result from an estimate or a statement that a function is available.
The acceptance protocol brief describes how to agree material, measurements and deviations before a trial. This article addresses a different decision: how that evidence relates to the later installed arrangement. A well-recorded factory trial can still leave site-specific questions open.
List changes between the two locations
Compare the accepted factory configuration with the installed project documentation. Identify changed interfaces, connected equipment, material handling arrangements and other relevant conditions for review. Do not assume a change is harmless or automatically requires a complete repeat; record it and ask the responsible engineer to decide its effect on the evidence.
Use the installation planning brief for the site information package. Actual electrical, foundation, lifting and safety requirements must come from the selected machine documentation and qualified site specialists. This evidence map is not an installation or operating instruction.
Assign one of three evidence statuses
Use “applicability to be reviewed,” “accepted for the stated scope” or “additional evidence required,” with an accountable reviewer and reason. Avoid a simple carried-over checkmark that hides the basis of acceptance. If the original result cannot be connected to the delivered configuration, keep that identification gap visible.
Where additional evidence is requested, specify the question it should answer. A repeat may concern a site-dependent interface rather than every function demonstrated at the factory. The qualified parties should define the safe procedure, required conditions and acceptance criteria. Purchasing should not improvise a machine trial to settle an undocumented question.
Use an evidence-transfer map
- Requirement or buyer decision: ____.
- Factory evidence reference and exact scope: ____.
- Factory machine/configuration and material references: ____.
- Installed configuration or interface reference: ____.
- Relevant difference or missing information: ____.
- Applicability decision and responsible reviewer: ____.
- Additional evidence requested, if any: ____.
- Site evidence reference, unresolved deviation and closure status: ____.
Keep the original result even when further evidence is required. The purpose is not to erase useful factory work, but to stop it being used outside its documented scope. If a question is closed by a document review rather than a repeat trial, record that basis clearly instead of implying that a site test occurred.
Separate arrival, readiness and acceptance
Physical receipt confirms that equipment arrived; it does not by itself confirm installation readiness, operational suitability or contractual acceptance. Use distinct milestones in the project record. A packing-list check and a technical acceptance decision can both be necessary without being the same event.
For any unresolved difference, record the owner of the next response and the evidence needed to close it. Use the agreed purchase and project terms for commercial decisions. This guide does not create new rejection rights, payment conditions, warranties or acceptance deadlines.
Request an evidence plan with the configuration
Send the candidate machine reference, intended material, target output, proposed site interfaces and the buyer’s acceptance questions through Nanyuan’s inquiry page. Ask which evidence can be produced at the factory and which questions depend on the completed site arrangement. Request a configuration-specific response rather than a general statement that testing is included.
Keep the resulting map with the accepted drawing and evidence register. When the configuration or interface changes, revisit only the affected conclusions with the responsible reviewers. This produces a traceable transition from factory observations to site decisions without promising that one demonstration proves every later operating condition.
