HEATER SYSTEM OF ELECTRIC CONSTRUCTION MACHINE
A heater system of an electric construction machine according to various embodiments of the present invention is a heater system of an electric construction machine which includes: a hydraulic pump driven by an electric motor; and a main control valve for supplying at least one actuator with working oil ejected from the hydraulic pump. The heater system comprises: a heater core which is located downstream of the actuator and through which the working oil passes; and a switching valve for selectively supplying the heater core with the working oil. Heated air can be supplied to a cabin through the heater core by using the heat of the working oil.
La présente invention porte, selon divers modes de réalisation, sur un système de chauffage d'une machine de construction électrique qui est un système de chauffage d'une machine de construction électrique qui comprend : une pompe hydraulique entraînée par un moteur électrique ; et une vanne de commande principale pour alimenter au moins un actionneur en huile de travail éjectée de la pompe hydraulique. Le système de chauffage comprend : un noyau de dispositif de chauffage qui est situé en aval de l'actionneur et à travers lequel passe l'huile de travail ; et une vanne de commutation pour alimenter de manière sélective le noyau de dispositif de chauffage en huile de travail. De l'air chauffé peut être fourni à une cabine à travers le noyau de dispositif de chauffage en utilisant la chaleur de l'huile de travail.
본 발명의 다양한 실시예에 따른 전기 건설기계의 히터 시스템은, 전기 모터에 의해 구동되는 유압펌프 및 상기 유압펌프로부터 토출되는 작동유를 적어도 하나 이상의 액추에이터로 공급하는 메인컨트롤밸브를 포함하는 전기 건설기계의 히터 시스템에 있어서, 상기 액추에이터의 하류에 배치되어 상기 작동유가 통과하도록 구비되는 히터 코어; 및 상기 작동유를 상기 히터 코어에 선택적으로 공급하는 절환 밸브를 포함하고, 상기 히터 코어를 통해 상기 작동유의 열을 이용하여 캐빈으로 가열 공기를 공급할 수 있다.
