液压泵比例 114-0616 电磁阀 挖掘机工程机械配件 电磁阀1140616

🔧 基本信息 (Basic Info)

• 零件号 (Part Number)：114-0616 (also 1140616, CA1140616)
• 中文名称：液压泵比例电磁阀 / 泵控电磁阀 / 流量控制电磁阀
• 英文名称：Hydraulic Pump Proportional Solenoid Valve / Pump Control Solenoid Valve / Flow Control Solenoid Valve
• 适配机型 (Compatible Models)：卡特 CAT330C, 336C, 312B L, 315B L, 317B LN 等系列挖掘机 (Caterpillar C-series excavators)
• 安装位置 (Mounting Location)：主液压泵调节器上 (On the main hydraulic pump regulator)
• Precisely adjusts hydraulic pump output flow to match engine power, preventing engine stall under heavy load.
• Receives PWM current signals from the ECU to control pilot pressure, regulating pump swashplate angle for stepless flow variation.
• Improves operation smoothness and work efficiency, avoiding jerky or weak combined movements.
• Weak hydraulic functions, engine stalling, speed drop, travel deviation, uncoordinated combined movements.
• Spool jamming, coil burnout, poor connector contact, internal leakage
