The flow pressure testing system control box developed and produced by Tianjin Runda Zhongke Instrument Co., Ltd. is an intelligent detection device designed specifically for fire water supply and hydrant systems. The control box of this system complies with the Technical Specification for Fire Water Supply and Hydrant Systems, and has the characteristics of high precision, high stability, and easy operation, providing reliable technical support for the performance testing of fire pumps.

According to the Technical Specification for Fire Water Supply and Hydrant Systems (GB50974-2014), the following are relevant provisions extracted from the specification:

① 5.1.11.2. The measurement accuracy of the fire pump flow detection device is 0.4 level, and 75% of the maximum range should be greater than 175% of the maximum design flow value of the fire pump;

② 5.1.11.3. The measurement accuracy of the fire pump pressure detection device is level 0.5, and 75% of the maximum range should be greater than 165% of the maximum design pressure value of the fire pump;

5.1.11 A set of fire pumps should be equipped with flow and pressure testing devices in the fire pump room, and should comply with the following regulations:

1. When the flow rate of a single fire water supply pump is not greater than 20L/s and the pressure is not greater than 0.50MPa, the pump unit should reserve interfaces for flow meters and pressure gauges, and other pump units should be equipped with flow and pressure testing devices;

2. The measurement accuracy of the fire water pump flow detection device should be level 0.4, and 75% of the maximum range should not be lower than 175% of the rated flow of the maximum fire water supply pump;

3. The measurement accuracy of the pressure detection device for the fire water pump should be level 0.5, and 75% of the maximum range should not be lower than 165% of the rated pressure of the maximum fire water supply pump;

4. Each fire pump outlet pipe should be equipped with a DN65 water test pipe and a DN65 fire hydrant should be installed.

The Technical Specification for Fire Water Supply and Hydrant Systems is an important basis for the design, construction, acceptance, operation and maintenance of fire water supply and hydrant systems in China. This specification sets clear requirements for the equipment, components, and performance of the fire water supply system, providing a unified standard for the performance testing of fire pumps. The control box of Runda Zhongke flow pressure testing system is developed and produced according to this specification, ensuring the compliance and reliability of the product.
