Technical Decoding | S.L Mechanical Servo System: Equipping Block Manufacturing with an "Energy-Saving Brain"

传统砌块制造长期面临能耗偏高、产品一致性欠佳等痛点。传统砖机普遍采用“PLC+变频器+异步电机”的开环控制模式——下达指令后缺乏实时反馈与修正，能量消耗较大；液压系统则存在明显的溢流损失，无论设备实际需要多少压力和流量，电机均保持全速运转。

Traditional block manufacturing has long faced challenges such as high energy consumption and poor product consistency. Conventional brick machines typically employ an open-loop control mode of "PLC + frequency converter + asynchronous motor"—lacking real-time feedback and correction after command issuance, resulting in significant energy consumption. Meanwhile, the hydraulic system suffers from notable overflow losses, where the motor operates at full speed regardless of the actual pressure and flow requirements of the equipment.

三联机械将伺服系统引入制砖机，构建起一套“闭环控制”体系。伺服系统由控制器、驱动器和伺服电机组成：控制器发出指令后，编码器实时反馈电机实际输出数据，系统根据反馈自动修正，精确控制速度和位置。简而言之：传统系统是“只管下达指令”；伺服系统则是“实时监督、动态修正”。

S.L Machinery introduced the servo system into brick-making machines, establishing a "closed-loop control" system. The servo system consists of a controller, drive unit, and servo motor: after the controller issues commands, the encoder provides real-time feedback on the motor's actual output data, enabling the system to automatically adjust based on this feedback for precise speed and position control. In short: traditional systems "only issue commands," while servo systems "monitor in real-time and dynamically correct.".

实测数据显示，三联机械电液伺服液压系统相较于普通液压系统，节能率超过30%，噪声降低10-20分贝，发热量大幅减少。在伺服振动系统中，每台伺服电机均为独立控制单元，克服了传统机械同步造成的能量相互抵消问题，每一度电都得到更充分的利用。

Test data shows that compared with conventional hydraulic systems, S.L Machinery's electro-hydraulic servo hydraulic system achieves an energy saving rate of over 30%, reduces noise by 10–20 decibels, and significantly reduces heat generation. In the servo vibration system, each servo motor acts as an independent control unit, overcoming the problem of energy cancellation caused by traditional mechanical synchronization, so that every kilowatt-hour of electricity is utilized more efficiently.

节能之外，伺服系统还带来多重综合效益。SLST系列生产线通过减少停机时间、降低废品率，实现综合成本的有效控制。伺服振动全闭环控制使激振力更加稳定，产品合格率得到提升；低噪音运行改善了车间工作环境。生产线还能够稳定利用建筑固废、钢渣、炉渣、煤矸石、洗砂泥及渣土等多种废弃物，有效降低原材料成本 。

In addition to energy conservation, servo systems also bring multiple comprehensive benefits. The SLST series production line achieves effective cost control by reducing downtime and lowering scrap rates. The servo vibration full closed-loop control makes the excitation force more stable, and the product qualification rate is improved; Low noise operation has improved the working environment in the workshop. The production line can also stably utilize various types of waste, such as construction solid waste, steel slag, slag, coal gangue, sand washing mud, and muck soil, effectively reducing raw material costs.

从“开环”到“闭环”，从粗放供能到按需供能——三联机械伺服制砖系统正推动砌块制造向更高效、更精准的方向演进。

From "open-loop" to "closed-loop", from wasteful energy supply to on-demand energy supply — S.L Machinery's servo brick-making system is driving block manufacturing toward greater efficiency and precision.
