FaucetAs an important part of the bathroom system, it is widely used in every home, and there are more than one.

As a necessity in the house, people's requirements for faucets are constantly increasing.faucetSealing and blocking performance, is becoming the core competitiveness of relevant enterprises.

picture1-1 Faucet diagram (source network)

The faucet is composed of a valve core, a main body, and an internal structure.

The internal structure consists of connecting goosenecks, flushing pipes, sealing rings, lower packing boxes, and connecting center pipes and other accessories.

The hot and cold faucet valve core has two hot and cold holes, and has a sealing ring to ensure sealing performance. The valve core mainly controls the opening and closing status of the two holes.

So how do we perform air tightness testing (waterproof testing) on ​​faucets?

Faucet air tightness detection solution

Testing requirements

1. Test the air tightness of the faucet switch when the faucet is turned off;

2. Test the faucet switch for obstruction (flow rate) while the faucet is open;

3. After the faucet test is completed, drain the remaining water inside the faucet.

Clamp: According to the usage characteristics of the faucet, the clamp is designed with Sai steel material to prevent the product from being scratched during loading and unloading.

Seal: the sealing component of the faucetUse original water pipes。

Equipment: During the testing, the Hirays faucet air tightness testing equipment was used. Its main functions include air tightness testing, flow testing, and air blowing and moisture removal.

According to customer requirements, this timeIP68 waterproof standard, using air tightness testing equipment isHirays HD-28 embedded differential pressure type, embed 4 HD-28 units into floor-standing tooling, and the four detection channels operate independently without interfering with each other.

Testing principle: Differential pressure and direct testing (semi-finished products) are used.

picture2-2 Principle of differential pressure detection of semi-finished products

The differential pressure pressurizes the standard part and the tested part at the same time (the standard part does not leak by default). The differential pressure sensor calculates the pressure difference between the standard part and the tested part. If there is no difference, it means there is no air leakage. If there is a difference, it means there is air leakage.This process is based on the comparison between the reference part and the tested part.

Test process:

Manual clamping→ Start → Stabilize voltage → Test → Exhaust → Water check → Dehumidify → Remove the product.

Detailed description of device functions

1. Valve core air tightness detection: When the single water or double water faucet valve core is closed, the leakage of the valve core is detected through differential pressure air tightness;

2. Valve core water detection: When the single water or double water faucet valve core is opened, the opening of the valve core is detected by pressing in real water;

3. Automatic dehumidification by water supply: After the water supply test, high pressure is automatically input and the residual water is blown out;

4. One-to-four design: One person can operate 4 workstations at the same time, which is efficient and can be started at the same time or separately without affecting each other;

5. Computer host computer: equipped with powerful host computer software, which can display/input/select various parameters (functions) and output reports;

6. Scan code test: realize one-to-one correspondence between product QR code and test results to facilitate traceability;

7. Can be connected to MES: Through secondary development, it can be connected to the factory-side MES system to facilitate data statistics and quality monitoring;

8. Compatibility: By simply switching the fixture, light ring faucets, smart faucets, Turing faucets, and faucet detection can be realized;

9. Quick replacement of consumables: The consumables are designed to simulate the customer's usage environment, have long lifespan and are easy to replace;

10. Reserve various interfaces: moisture drainage interface, flashing function threading interface, etc.

This equipment is mainly used for sealing testing and functional testing of faucets in the bathroom industry; the equipment consists of differential pressure testing instruments,It consists of three parts: PLC system and tooling and fixture system.

About Hai RuisiHD-28 Ingenuity Series

picture3-1 Hirays HD-28 embedded differential pressure type

• Differential pressure testing method, with high accuracy and better stability;

• The software automatically compensates for test differences caused by temperature rise caused by long-term operation of the solenoid valve;

• Provide PC-side Demo program to facilitate secondary development;

• Very competitive prices;

Superiority

1) High resolution:0.1pa, the highest resolution of Hirays air density meter;

2) High stability: Differential pressure principle, comparison of both sides at the same time;

3) Quick to get started: No need to click any buttons, just enter the pre-test settings to adjust the pressure;
