An electric heating preheating device

Abstract

The invention discloses an electrical heating preheating device. The electrical heating preheating device comprises a box and a water tank; the electrical heating preheating device is characterized in that the water tank is arranged in the box and is of a down-in up-out structure, a water inlet is formed in the bottom of the water tank, a water outlet is formed in the top of the water tank, and a circulation pump is arranged on the water inlet; and an electrical heating body is arranged on the water tank, and a heating control assembly is arranged in the box, is connected with the electrical heating body and controls the electrical heating body to heat water in the water tank. The electrical heating preheating device is simple in structure, the occupied size is small, the machining and assembling difficulty is low, emission is avoided, the environment is effectively protected, energy conservation and environmental protection are achieved, the energy conversion efficiency is high, the cost for preheating a locomotive is reduced, the preheating efficiency is improved, and the using safety is high.

Description

technical field [0001] The invention relates to the technical field of preheating devices, in particular to an electric heating preheating device. Background technique [0002] The operation and maintenance of the locomotive stipulates that when the cooling water temperature is lower than 20°C, the diesel engine is not allowed to start. The temperature of engine oil and cooling water is too low, which not only causes serious wear and tear of moving parts, but also makes fuel atomization and combustion poor, making it difficult to start the diesel engine. For this reason, a preheating system is installed on the diesel locomotive to ensure that the diesel engine can start at the specified oil and water temperature, or maintain a certain oil and water temperature when the shutdown time is long, so as to prevent the cooling water of the locomotive from freezing and being damaged in winter parts. [0003] The traditional preheating device is an oil-fired boiler. The preheating ...
