液压起重机起升机构液压系统是起升机构工作的动力和控制的手段,它的选择是否合理,对起重机的性能有着很大的影响,并且直接影响起重机工作的安全可靠性和效率。目前国内外液压起重机起升机构液压系统的形式繁多。从系统的油路循环形式分:有开式系统和闭式系统;从液压泵和液压马达的形式分:有定量式系统和变量式系统;从液压泵和液压马达不同数量的匹配分:有单泵马达,双泵单马达,单泵双马达,双泵双马达。各种系统的形式不同,其性能也不
The hydraulic system of hydraulic crane lifting mechanism is the power and control method of the lifting mechanism. The choice of whether it is reasonable has great influence on the performance of the crane and directly affects the safety, reliability and efficiency of the crane. At present, there are many kinds of hydraulic systems of hydraulic crane lifting mechanism at home and abroad. From the system’s oil circuit circulation form: There are open systems and closed systems; from the hydraulic pump and hydraulic motor in the form of: there are quantitative systems and variable systems; from the hydraulic pump and the hydraulic motor different number of matching points: There are Single pump motor, double pump single motor, single pump dual motor, double pump dual motor. Different systems have different forms and their performance is not
