Housing Dry Air Tightness Tester Description — Automated Faucet Leak

The housing dry air tightness tester is an automated leak detection machine for faucet, spout, valve and pipe-fitting manufacturers. It performs dry-air pressure leak tests on machined cast housings per relevant standards. Compressed air fills the product cavity, followed by pressure holding and leakage detection — fully automated by a PLC and touch HMI that outputs a clear pass/fail result. Pneumatic fixtures with rubber gaskets seal every opening, while sensors compare real-time pressure against the threshold and alarm on excess leakage. Two independent stations raise throughput for faucet factories and OEM suppliers.

Machine Features

  1. Dry-Air Leak Test (0.05–0.6 MPa) — Pressurized dry-air method detects leaks without water, ideal for machined cast housings.
  2. Dual-Station Independent Operation — Two stations run independently to double throughput on faucet bodies and fittings.
  3. PLC + HMI Automatic Control — Xinje PLC and touch HMI automate inflation, stabilization, detection and pass/fail output.
  4. Pneumatic Clamping & Sealing — Rubber-gasket fixtures clamp and seal water inlets, outlets and cartridge positions.
  5. Auto Counting & Alarm — Records tested quantity; red light + buzzer flag leakage above the set threshold.

Application Fields

Faucet & Tap Manufacturers

Dry-air leak verification of cast faucet bodies before electroplating and assembly processes.

Valve & Spout Producers

Seal and passage leak testing on spouts, valves, and mixed-water outlet components.

Pipe Fitting & Plumbing Factories

Incoming quality control and in-line leak screening for pipe fittings and connectors.

OEM & Contract Suppliers

Documented pass/fail leak testing and quality traceability for private-label faucet lines.

R&D & Quality Laboratories

Pressure-decay method validation, process parameter tuning, and design quality verification.

Q: What does the housing dry air tightness tester do?
A: It performs dry-air pressure leak tests on faucet, spout, valve and pipe-fitting cast housings, automatically outputting a clear pass/fail result.

Q: What pressure range can it test?
A: Test air pressure ranges from 0.01 MPa to 0.8 MPa, with leak-detection sensitivity down to 0.0002 MPa accuracy; the supply air pressure required is ≥0.6 MPa.

Q: How many stations does it have?
A: It has two independent stations with identical function — each can test a product on its own, effectively doubling throughput.

Q: Is the operation automatic?
A: Yes. A Xinje PLC and touch-screen HMI control inflation, pressure stabilization, detection and result output automatically, including auto counting of tested pieces.
