Fire fighting truck water pump chamber automatic heating system

Abstract

The invention relates to a fire fighting truck water pump chamber automatic heating system. The fire fighting truck water pump chamber automatic heating system comprises a fan heater (1), an electromagnetic pump (2), a temperature sensor (3), a fire fighting truck oil tank (4) and a fan heater switch plate (5), wherein the fan heater, the electromagnetic pump and the temperature sensor are mountedin a fire fighting truck water pump chamber; an oil outlet of the electromagnetic pump communicates with the fan heater; an oil inlet of the electromagnetic pump communicates with the fire fighting truck oil tank; the electromagnetic pump is connected with a fan heater controller (6); the temperature sensor is connected with the fan heater controller; the fan heater switch plate is mounted in a fire fighting truck cab; a fan heater switch (51), a power light (52) and a thermoregulation potentiometer (53) are arranged on the fan heater switch plate; and the positive power output end and the negative power output end of the fan heater switch plate are connected with the fan heater controller. The fire fighting truck oil tank is used for supplying oil to the fan heater, thus, oil supply of the fan heater is ensured, the phenomenon of burn-in of the fan heater caused by oil shortage is avoided, and long-term reliable operation of the fan heater is facilitated.

Description

technical field [0001] The invention relates to a fire truck, in particular to an automatic heating system for a water pump chamber of a fire truck. Background technique [0002] The northern region is relatively cold in winter, and the water pump room on the fire truck needs to be heated in winter to ensure the normal operation of the fire pump. The fuel tank capacity of the heater in the heating system of the water pump room of the existing fire truck is relatively small, which cannot guarantee the long-term reliable operation of the heater. If the fire pump on the fire truck is frozen before and during use during the winter fire fighting process, it will not be able to operate normally, which will directly affect the smooth completion of the fire fighting task of the fire truck, and will bring unnecessary trouble to fire fighting and rescue. Losses will also affect the credibility of the fire department. Contents of the invention [0003] The purpose of the present in...

AI Technical Summary

Problems solved by technology

The fuel tank capacity of the heater in the heating system of the water pump room of the existing fire truck is relatively small, which cannot guarantee the long-term reliable operation of the heater, and it is prone to the phenomenon of the heater lacking oil and burning. After the heater stops working, the temperature in the water pump room will drop rapidly.

If the fire pump on the fire truck is frozen before and during use during the winter fire fighting process, it will not be able to operate normally, which will directly affect the smooth completion of the fire fighting task of the fire truck, and will bring unnecessary trouble to fire fighting and rescue. Losses will also affect the credibility of the fire department
