搅拌车液压系统的两种类型介绍

来源:http://www.zkzdsljbc.com/ 时间:2021-05-25

搅拌车的液压系统通常分两大类:开式系统与闭式系统,当前市场的品牌以开式系统为主,大方量搅拌车以闭式系统为主,结构紧凑,可靠性高,下边对两种结构进行详解,教你如何识别:
The hydraulic system of the mixer is usually divided into two categories: open system and closed system. The current market brand is mainly open system, and the large quantity mixer is mainly closed system, with compact structure and high reliability. The following two structures are explained in detail to teach you how to identify them

两个定量齿轮泵4、5。在低速状态,液压泵4向液压马达13供油;高速状态,油泵4、5同时向液压马达13供油。液压泵4、5的排油量是不同的,主要根据高速与低速供油状态的转速而定。换向阀8控制搅拌筒正反转,溢流阀7起过载保护作用。溢流阀9、12与单向阀10、11起着防冲击的补油保护作
自动上料混凝土搅拌车
Two fixed displacement gear pumps 4, 5. At low speed, the hydraulic pump 4 supplies oil to the hydraulic motor 13; At high speed, oil pumps 4 and 5 supply oil to hydraulic motor 13 at the same time. The oil displacement of hydraulic pumps 4 and 5 is different, mainly depending on the speed of high-speed and low-speed oil supply state. The reversing valve 8 controls the forward and reverse rotation of the mixing drum, and the overflow valve 7 plays the role of overload protection. Relief valves 9 and 12 and check valves 10 and 11 play the role of anti impact oil supplement protection.
伺服液压缸2控制柱塞变量泵斜盘的方向与倾角,用来调节柱塞泵3的方向与排量。高压溢流阀12能防止系统过载,起保护作用。两个高压溢流阀的开启压力值可根据液压马达两侧油路的负载分别调定,以适应不同工况的要求。
Servo cylinder 2 controls the direction and inclination of the swash plate of the piston variable displacement pump, which is used to adjust the direction and displacement of the piston pump 3. The high pressure relief valve 12 can prevent the system from overload and play a protective role. The opening pressure of the two high pressure relief valves can be adjusted according to the load of the oil circuit on both sides of the hydraulic motor to meet the requirements of different working conditions.
特点
characteristic
通过发动机的油门来调节转速,能耗大、不经济。需要大油箱,结构庞大;液压油中易混入空气,振动与噪声大,可靠性差、寿命短。
Adjusting the speed through the throttle of the engine consumes a lot of energy and is not economical. Large fuel tank and huge structure are needed; The hydraulic oil is easy to mix with air, and has high vibration and noise, poor reliability and short service life.
通过柱塞变量泵斜盘调整转速、转向,结构紧凑,油箱容积小,散热要求高,工作稳定,可靠性高、寿命长。
By adjusting the speed and steering through the swashplate of the piston variable displacement pump, the structure is compact, the volume of the oil tank is small, the heat dissipation requirement is high, the work is stable, the reliability is high, and the service life is long.
