Product Details

Introduction

This gas water heater detection equipment adopts a computer centralized distributed measurement and control system. The overall system mainly consists of an industrial control computer, a data acquisition board, and various types of sensors. The data acquisition board collects sensor signals, processes them, and returns them to the industrial control computer. The upper computer software of the industrial control computer is installed to process and calculate the data and implement it.

This gas water heater detection equipment is divided into two parts in terms of hardware: one is the equipment rack and pipeline, and the other is the electrical control system.

Adopting a combination of manual and automatic control, ball valves are installed on the main inlet pipe and main inlet pipeline, which are normally in a normally open state. In case of abnormal situations, manual intervention can be carried out to cut off water and gas to ensure safety. Other normally tested pipelines are equipped with solenoid valves, which can be controlled by the electrical control system to control the on/off of water and gas.

The hardware acquisition and control of the current model gas water heater detection system meet the energy efficiency level testing and some routine tests, including GB6932, EN26, EN13203-2&Regulation 812, 814 (European standard ERP), 10CFR Pt.430 Subpt. B APP. E (American standard DOE), AS5263.1.2 (Australian standard).

The current model supports pre adjusted water flow functions in both hardware and software, including ERP and DOE testing, making the testing process more accurate.
