The computerized gas heating furnace performance testing equipment is a high-precision comprehensive performance testing system developed by Zhongshan Wanhe Testing Equipment Development Co., Ltd. based on current national standards for gas heating water boilers (wall-hung boilers). This equipment is based on a computer + PLC collaborative control architecture, using imported high-precision sensors for data acquisition and processing, achieving fully automated operation of the testing process. It is a key testing device for gas heating furnace R&D testing, online production inspection, and quality inspection agency conformity assessment

1. Equipment Purpose

The equipment is developed based on "GB6932-2015 Household Gas Rapid Water Heaters," "GB25034-2010 Gas Heating Water Boilers," "CJ/T395-2012 Condensing Gas Heating and Bath Dual-Use Boilers," "CJ/T336-2010 Condensing Household Gas Rapid Water Heaters," and the energy efficiency standard "GB20665-2015 Energy Efficiency Limits and Grades for Household Gas Rapid Water Heaters and Gas Heating Furnaces." It is mainly used for comprehensive performance testing such as heat load and energy efficiency grade of gas heating water boilers. It is suitable for R&D testing and inspection tests by water heater and heating furnace manufacturers, with quality inspection units conducting product qualification evaluations.

2. Core architecture of computerized systems

Unlike traditional instrument-type testing equipment, the computer-type gas heating furnace performance testing equipment uses a computer+PLC programmable controller collaborative control method to achieve automated and intelligent operation of the testing process:

Computer as the control and data processing hub: Testing functions are designed according to national and European standards, and microcomputer technology is used to transmit test parameters and control signals between the computer and the testing system. The computer system acts as the control record, and through a user-friendly and flexible human-machine interface, automated test control can be achieved.
PLC real-time control: The programmable controller is responsible for real-time on/off control of solenoid valves and corner seat valves in water and gas circuits, executing automated testing processes. The testing system uses computers combined with PLC programmable controllers, combined with imported sensors for data collection, ensuring high testing accuracy, stable performance, and long service life.
User-friendly human-machine interface: Operators can intuitively monitor various test parameters via computer screens, supporting parameter settings, real-time data display, data collection and storage, automatic storage of original records, convenient query and management, and automatic generation of test reports.
Real-time monitoring and alarm protection: The testing system has real-time recording and monitoring functions for test parameter data. After the heating furnace operates stably, if any abnormal parameters occur during testing, the system immediately triggers an alarm and automatically stops the furnace's operation. The computer display interface displays the corresponding parameters in red, making it easy to identify fault causes and ensuring accuracy and safety.

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.
