Centrifugal fire pump

Abstract

The invention relates to the technical field of fire pumps, in particular to a centrifugal fire pump. The centrifugal fire pump comprises a sealing bin, a bottom frame and a bottom plate, the bottom frame is connected with the bottom plate, two mother gears and two son gears are connected between the bottom frame and the bottom plate, mounting lugs are connected to the mother gears and the son gears through connecting strips, and the sealing bin is mounted below the bottom frame. The sealing bin communicates with an input pipe connector and an inlet pipe connector, an efficient water wheel is mounted in the sealing bin, a fuel tank and an internal combustion engine are mounted on the bottom frame, and the fuel tank communicates with the internal combustion engine. An oil filling pipe communicates with the fuel tank, a fire extinguisher is mounted on the bottom frame, the bottom frame is connected with a mounting plate through an auxiliary frame, a standby water cylinder, an auxiliary electronic system and a fire insulation device are mounted on the mounting plate, an electromagnetic valve is mounted at the bottom end of the standby water cylinder in a communicating mode, and the electromagnetic valve communicates with the sealing bin through a bent pipe. The centrifugal fire pump can better adapt to various mounting environments, the practicability is good, self-protection can be achieved, the damage probability is reduced, and water can be automatically supplemented into the sealing bin.

Description

technical field [0001] The invention relates to the technical field of fire-fighting water pumps, in particular to a centrifugal fire-fighting water pump. Background technique [0002] As we all know, the centrifugal fire pump is a special pump installed on fire trucks, fixed fire extinguishing systems or other fire fighting facilities to transport liquid fire extinguishing agents such as water or foam solutions. It has the characteristics of full sealing, no leakage and corrosion resistance. It is an important core soul unit in the fire protection system. It is widely used in modern urban fire protection construction and plays an important role in the safety of people's lives and property. [0003] Existing centrifugal fire pumps generally include a pump body, the pump body includes a mounting base and a motor, the mounting base is fixedly connected with mounting ears, the mounting ears are provided with strip holes, the pump body is equipped with a sealing chamber, and the...

Problems solved by technology

[0004] However, during the installation and fixing process of the above-mentioned central centrifugal fire pump, it is necessary to preset the installation structure that matches the mounting lugs on the mounting base, which is limited by the installation position and has poor practicability, and when the fire spreads to the centrifugal fire pump Once the location where the centrifugal fire pump is installed catches fire, it is very easy to cause damage to the centrifugal fire pump, and the self-protection effect of the centrifugal fire pump is poor. When it is not started for a long time, the water in the sealed chamber will be lost, which will affect the re-starting of the centrifugal fire pump
