Two- and three-component automatic gas distribution system WH-ZD09-1003

The WH-ZD09-1003 fully automatic gas distribution device is a high-level fully automatic gas distribution device developed according to relevant national gas appliance standards for gas appliance manufacturers and gas companies. This device uses three (or two) single-component raw gas—hydrogen, propane (methane, liquefied petroleum gas), and nitrogen—and can prepare various artificial and natural gas test gases that meet national standards. This equipment uses a low-pressure gas distribution method, using continuous and single-batch gas distribution to prepare three-component test gases, meeting the requirements for actual combustion and testing experiments on gas appliances that use artificial coal gas and natural gas. This equipment has high gas distribution, operates quickly, maintains good consistency, and is very convenient to manage and operate. It can store multiple sets of data and is unaffected by power supply switches, making it convenient and fast to use as needed. This equi

1. Product Introduction

3. Basic Requirements Before Installation

1. Work site

◆ The gas supply room needs to be 8-12m², with a door width of no less than 1000mm and room height of no less than 2300mm. The site should be equipped with a powerful explosion-proof ventilation fan, which must be synchronized with the equipment

Done.

◆ The site should be equipped with no fewer than four fire extinguishing devices, with specific models meeting fire safety requirements; Lighting fixtures should be explosion-proof.

◆ The source gas cylinder chamber needs to be 3-4m², with a floor height of no less than 3600mm, and one side should be open.

2. Supporting facilities (to be handled by the user)

◆ Water supply – Each site should have a dedicated water source (mainly for filling air tanks), with G1/2 ball valves reserved at the water source terminal (no water nozzle); Requires an inner diameter of 10-12mm

One plastic tube (no less than 5m).

◆ Water Supply - Each site should be equipped with a dedicated compressed air source (mainly to replace nitrogen when preparing two components), and a two-piece (pressure regulation plus filtration) should be installed at the outlet

However, the interface is pre-installed with Φ8 PU plastic hose.

◆ Power Supply - Each site should be equipped with a power socket (three-outlet and effectively grounded), supplied by AC220V single-phase power with a rated current of no less than 2.5A.

3. Drainage - Each site should have a pre-installed drainage outlet, with a pipe diameter of no less than Φ50mm and a height above ground not exceeding 100mm

4. Source gas cylinder group (responsible for the party in charge)

◆ Hydrogen – Each unit should be equipped with at least one bottle of hydrogen (purity must meet GB/T13611-92 standard) and a dedicated pressure reducing valve matching it.

◆ Nitrogen – Each unit should be equipped with at least one bottle of nitrogen (its purity must meet GB/T13611-92 standard) and a dedicated pressure reducing valve matching it.

◆ Propane - Each unit should be equipped with no fewer than one bottle (50Kg or 15Kg) of propane (purity must meet GB/T13611-92 standard). If purchasing is difficult, it may be optional

Paired with commercial imported liquefied gas sources with better gas quality.

◆ Each bottle set should be equipped with three high-pressure (pressure resistance not less than 1Mpa) corrosion-resistant rubber hoses with an inner diameter of 8-10mm, each 2.5m long (if the source gas cylinder is far from the distribution chamber,

then lengthen the length appropriately according to actual circumstances).

Frequently Asked Questions

What industries is your company's testing equipment mainly suitable for?

We specialize in non-standard testing equipment for gas appliances and household appliances, especially in the gas appliance industry, with nearly thirty years of technical accumulation in the gas appliance industry, including gas water heaters, wall-hung boilers, and gas stoves. At the same time, the equipment is widely used in kitchen appliances such as range hoods, electric ovens, and sterilizers, as well as in environmental reliability testing fields like salt spray tests and high and low temperature tests. In addition, industrial automation inspection solutions can be customized according to customer requirements.

Do you make standard equipment or non-standard customization?

Focusing mainly on non-standard customs. Each production line and every product category has unique testing requirements. We provide a full range of customized services from solution design, mechanical manufacturing, electrical control, to software integration based on your inspection targets (such as valve bodies, complete machines), inspection items (performance, aging, lifespan), production line cycles, and environmental conditions. There are already numerous successful non-standard cases in the gas appliance and home appliance industries for reference.

How is the precision and stability of the equipment? How to verify it?

Before leaving the factory, we conduct complete machine testing and precision calibration according to national or industry specifications, and can provide actual measurement data reports. Common verification methods include: repeated testing with standard samples, comparison with customers' existing qualified equipment, or testing by third-party metrology agencies. For key parameters such as gas flow, pressure, and temperature, we also provide calibration recommendations and cycle reminders. For projects requiring extremely high precision, free sample testing can be arranged.

How long does it take to customize a device? Will it affect my production?

The project duration depends on the complexity of the equipment, generally 4~8 weeks, and includes requirements confirmation, solution design, manufacturing, factory pre-commissioning, and on-site installation. We complete pre-assembly and functional testing of the entire machine in the factory, and only a short time of wiring and fine-tuning can be done on site for trial operation. We will communicate with you in advance about the production shutdown window and develop a detailed installation schedule to minimize the impact on production.

Is the equipment complex to operate? What training do you offer?

The equipment uses a touchscreen human-machine interface, with simple operation logic; ordinary workers can use it daily after half a day of training. We offer tiered training: operator training (power on/off, data retrieval, fixture change), technician training (parameter adjustment, simple fault handling), and engineer training (system configuration, deep maintenance). It also provides a library of operation videos and illustrated manuals for easy access at any time.
