적용 범위
This standard applies specifically to water tank fire fighting vehicles and is referenced for water supply fire fighting vehicles. It covers the terminology, technical requirements, testing methods, and inspection rules for these specialized vehicles. Manufacturers of fire trucks entering the Chinese market must comply with these specifications. It does not apply to other types of fire fighting vehicles such as foam or dry chemical trucks, which are covered under separate parts of the GB 7956 series.
기술 요구 사항
The standard mandates comprehensive requirements for the entire vehicle configuration, including fuel tank capacity, engine speed controllers, and manual emergency measures for automatic control mechanisms. It requires specific operational panels with clear markings, pressure displays, and water pipeline schematics. For the chassis modification, the standard specifies that the tank body must be elastically connected to the chassis without direct contact. The fire hydraulic system requirements are extensive, covering the fire pump, piping, water tank, and fire monitor. Piping must use corrosion-resistant materials and be color-coded according to GB/T 3181. The standard sets strict criteria for the water tank construction, including volume tolerances, anti-splash plates, manhole covers, and pressure resistance. It also details the performance of the fire monitor, requiring specific depression angles and locking mechanisms. Additionally, it outlines requirements for maximum vacuum degree, priming time at maximum suction depth, and continuous operation tests to ensure engine and pump reliability under prolonged use. Vehicle instrumentation, equipment placement, and accompanying documentation must meet mandatory criteria.
시험 방법
Testing procedures include verifying the fuel tank capacity by running the vehicle at rated flow and pressure for 2 hours after a 100km drive. Hydrostatic pressure tests are conducted on inlet and outlet pipelines to check for leaks and structural integrity. The standard mandates a maximum vacuum degree and sealing test to ensure the priming system's efficiency. A maximum suction depth test evaluates the pump's performance and priming time at a 7m suction depth. Furthermore, a 6-hour continuous operation test is required to monitor engine temperature, vibration, and leaks, followed by an overload operation test to verify performance under 1.1 times the rated pressure. Equipment and documentation are verified through visual inspection and inventory checks against the standard's requirements.
