The invention discloses a system of using carbon dioxide of shielded welding to quickly lower the temperature of a pile machine oil box, which relates to a system of utilizing carbon dioxide to reduce temperature. The system of the invention contains a carbon dioxide steel bottle, a welding machine and a pile machine oil box, and is characterized in that heat-exchanger tubes are installed in the oil inside the shell body of the pile machine oil box, a connecting hose is installed between the air inlet of the heat-exchanger tube and the steel bottom air outlet of the carbon dioxide steel bottom, and a connecting hose is installed between the air outlet of the heat-exchanger tube and a welding handle. The heat-exchanger tube is a straight tube, a bent tube or a twisted tube. The system has reasonable design, simple structure, easy implementation, which can successfully resolve two technical problems without any cost and any pollution problems and is a win-win technical proposal.
Description
technical field [0001] The invention relates to a cooling system using carbon dioxide, in particular to a system for rapidly cooling the oil tank of a pile driver by using liquid carbon dioxide contained in a protective electric welding cylinder. Background technique [0002] When the pile driver of the prior art works, the temperature of its hydraulic oil tank is very high, which often causes the oil cylinder to fail to work normally, and generally adopts a shutdown to cool down naturally or an electric fan to cool down. A large amount of carbon dioxide protective electric welding is used for welding the pressed pile section in the pile machine work site. The carbon dioxide for the protective electric welding is supplied by the liquid carbon dioxide in the steel cylinder. In order to ensure that the temperature of the carbon dioxide used is not too low, the steel cylinder and the electric welding machine The decompression pipeline is often used to decompress and absorb heat...
