Turn the component’s failure into a measurable test
Yuyao Hang’an Machinery Equipment Co., Ltd. describes development and manufacture of airtightness/flow testing equipment, alongside torque testers, brake testers and other equipment. Its application categories include pumps, solenoid valves, pipes and castings. [1] This is upstream component-production equipment; the reviewed sources do not establish Hangan as a construction-machine or water-pump manufacturer.
The pump category contains a three-station tester and two separate two-station water-pump tester entries. [2] Their presence does not establish suitability for a specific hydraulic pump, pump housing or engineering-machine assembly. Ask the supplier to connect the proposed test to your exact part and failure requirement.
The two-station listing mentions PLC/HMI, sensor and test modules, automatic sealing, result decisions and HMI data storage. [3] These are supplier-described system features. Published text does not identify the actual sensor range, leak method, measurement uncertainty or export format.
Separate a leaking part from a leaking fixture
The supplier says the system automatically seals the workpiece cavity. That makes fixture design part of measurement quality, not merely a loading convenience. Include all sealing surfaces, ports, tolerances, acceptable clamp contact and product variants in the drawing sent for review.
| Boundary | Buyer supplies | Supplier demonstrates |
|---|---|---|
| Measured cavity | Drawing with included/excluded passages and all openings. | Test-circuit drawing identifying each seal, supply and sensing point. |
| Fixture contact | Surface condition, dimensional variation and protected features. | Repeat loading and sealing without unacceptable damage or false failures. |
| Variant change | Different port layouts and part identification. | Required tooling, recipe selection and prevention of the wrong test. |
| Failure investigation | Known good and known defective examples with agreed status. | A method for distinguishing part failure from a fixture or connection fault. |
Request the maintenance and replacement boundary for seals, adapters and connectors. Confirm who supplies variant tooling and how a changed fixture is checked before production resumes.
Buy an accepted decision, not an animated demonstration
- Release the method: agree measured quantity, test medium, safe pressure range, timings and pass/fail criteria with competent engineers.
- Challenge the decision: run agreed passing and failing references at each station, including repeat loading.
- Record the configuration: retain instruments, calibration evidence, software/recipe version and fixture identification.
- Prove the workflow: observe loading, testing, safe release, unloading and failed-part handling together.
- Retrieve the result: demonstrate the agreed part/station/time/result record and its retention/export process.
“High precision” and improved productivity appear in the catalogue without numeric conditions. Do not turn them into a promised accuracy or parts-per-hour figure. Agree repeatability and complete-cycle acceptance for the purchased configuration.
HSE GS4 discusses stored-energy risks, safeguarding and maintenance of pressure-test connections. [5] Use competent, site-specific review of the proposed test circuit and release sequence. The illustration is not evidence of protective performance or conformity; this general guidance does not certify Hangan.
Keep the entity, contact site and project responsibilities explicit
Business-registration data identifies 余姚市航安机械设备有限公司, incorporated on 18 September 2015, with registered address Mazhu Town, Zhubei Village (渚北村), Yuyao. The official contact phone matches the original record; its current address is 98 Dongheng Road, Mazhu, Yuyao. [4] This is a contact reference, not a factory inspection.
The website timeline separately labels registration in 2015 and formal establishment in 2016. Retain that distinction rather than presenting two incorporation dates. Its named historical projects are supplier statements, not independently verified customer endorsements.
Confirm the quotation issuer, equipment build/trial location and who owns mechanical fixtures, control software and commissioning. Ask for acceptance, training, documentation and support responsibilities in the order.
