Hangan two-station water-pump tester

The official designation is “两工位水泵测试机”, meaning two-station water-pump tester. Entry12 shows two blue pump-shaped workpieces and central controls. [1] It is an equipment illustration, not proof of a running machine or a delivered configuration. No alphanumeric model code is published; “12” is a website reference, not a product model.

A separate entry13 uses the same name and description with a different illustrated fixture/control arrangement. [2] The site does not explain whether these are options, revisions or different projects. Refer to the actual entry and obtain a current drawing; do not merge their visible features into one specification.

A water-pump testing title does not establish an approved hydraulic-pump test bench or a head/flow/efficiency curve capability. Ask which measured quantities and operating conditions the offered system actually supports. The catalogue’s pneumatic-component brand references are not a controlled bill of materials.

Determine test pressure and timings through the responsible engineering process; this page supplies no operating recipe. HSE GS4 treats pressure testing as stored-energy work and addresses safe systems, segregation and maintained test connectors. [3] Its guidance is general and does not validate the protection shown in this illustration.

Ask how the fixture is checked for leaks and wear, how sealed surfaces tolerate part variation and whether changeover needs new tooling. A failed cycle should trigger a defined investigation, not an automatic assumption that the component is defective.

• Can each position load, test and report independently, or does one shared sequence control both?
• Is the part and result assigned to the correct station throughout the cycle?
• Can a fixture fault or interrupted test at one position affect the other result?
• How are failed and untested parts identified and separated from accepted parts?
• What loading, release and unloading time belongs in the demonstrated complete cycle?

The reviewed text does not resolve these questions. Request a sequence chart and run representative parts in both positions. Include the agreed challenge where one position receives a failing reference and the other a passing one. Observe whether decisions and records remain correct.

Do not double a claimed single-station rate to estimate output. Shared utilities, handling and sequential operations may determine capacity; the actual ordered sequence must be demonstrated at the agreed load.

The official description says test results and data are stored through the HMI for quality analysis and later traceability. [1] It does not publish capacity, retention, export protocol, database connection or MES compatibility.

Check recovery after an interrupted cycle and loss of power with the supplier’s safe procedure. Identify whether an incomplete record is distinct from a pass. No cloud dashboard, automatic ERP/MES link or export capability is claimed here.

1. Approve the current entry12-related configuration drawing and part/fixture family.
2. Specify included channels, instruments, test circuit, limits, controls and protective arrangements.
3. Agree representative samples and repeat-loading checks at both positions.
4. Demonstrate the complete workflow and retrieve station-specific records.
5. Deliver drawings, operating/maintenance documents, calibration evidence and agreed training.

Quote initial and variant tooling, replacement sealing parts, commissioning, software access, acceptance and support separately enough to compare offers. The source does not establish warranty duration, spare lead time or destination conformity; confirm the applicable requirements with the actual supplier and project team.
