Problems solved by technology

[0008] Since the heating system heats the fuel oil and the warm air at the same time, the flow through the fuel tank and the warm air system is not adjusted, so that the temperature of the warm air rises quickly, while the temperature of the fuel does not rise significantly, making the entire heating process It takes a long time, and the heat distribution of the heating system is uneven, resulting in low heating efficiency

Abstract

The invention discloses a heating system for a crane, which comprises a heater, wherein the heater is provided with a water inlet and a water outlet which is respectively connected with an engine oil tank and a heating air system, and an oil temperature control electromagnetic valve and a water temperature control electromagnetic valve are respectively arranged on a water path for heating the oil tank and the heating air system; an oil temperature sensor is arranged in the oil tank, a water temperature sensor is arranged in the water tank in the heating air system, and an electric control unit and an oil absorbing pump are arranged on a fuel oil pipe; and the electric control unit is used for comparing actual oil temperature and actual water temperature with a critical value respectively and adjusting the openness of the oil temperature control electromagnetic valve and the openness of the water temperature control electromagnetic valve according to comparison results. The heating system provided by the invention realizes synchronous heating of fuel oil and the heating air system and automatic temperature adjustment, is more balanced to heat and improves the heating efficiency.

Description

technical field [0001] The invention relates to the technical field of engineering control, in particular to a heating system for a crane. Furthermore, the invention also relates to a crane comprising the above-mentioned heating system. Background technique [0002] When the crane is working in an alpine environment, in order to start the crane quickly and the oil will not be blocked due to low temperature when the crane is working, it is necessary to preheat the fuel to ensure that the fuel supply is sufficient; at the same time, in order to ensure that during operation There is a certain suitable temperature in the cab for high-cold operation, and the heating system needs to be heated. [0003] At present, heaters are commonly used on cranes to heat the fuel tank and the warm air system to increase the temperature of the fuel and the preheating performance of the warm air. The specific structure of the heater is as follows: figure 2 As shown, the heater 1 is provided wit...
