Application of Zhufeng ACI servo in profile extrusion machine

Product Name:Servo control system for profile extruder

System composition:Servo controller+servo motor+oil pump+current and pressure feedback

• characteristic:

• Energy saving. The extruder adopts a servo system, with dual closed loops for system pressure and flow rate. The hydraulic system supplies oil according to the actual required flow rate and pressure, overcoming the high energy consumption caused by high-pressure overflow in ordinary quantitative pump systems. During the high flow working stage, the motor works at the set speed, and during low flow working stages such as feeding, tightening, squeezing, retreating, and tail cutting, the motor speed is reduced. The actual energy consumption of the oil pump motor is reduced by more than 30%.

• Quick response and high production efficiency. The servo system has a fast response speed, with a pressure rise time and flow rate rise time of up to 30ms, which improves the response speed of the hydraulic system, reduces action conversion time, and accelerates the overall running cycle of the machine; When the hydraulic system of the press is running automatically, when a valve is opened, the system pressure will instantly decrease. The servo system can quickly replenish the oil volume within 30ms and restore the pressure to the set value.

• Stable and precise pressure. The servo system has strong adjustment capability, and the pressure closed-loop control mode makes the system pressure very stable. The pressure fluctuation is less than ± 0.5 bar, which improves the forming quality of the product; The servo system can also operate according to any pressure and flow curve set by the computer, creating conditions for the development of various product forming processes.

• Low oil temperature rise. The profile extruder works from start-up to steady-state, and the oil temperature rises by 8 ℃ -10 ℃. At room temperature of 35 ℃, no cooling water is required, and the amount of cooler used is greatly reduced, which extends the life of the entire machine, especially hydraulic oil and hydraulic vulnerable parts (such as oil seals).

• Low noise. The noise of the hydraulic system is within 65 decibels, which improves the on-site environment for operating the machine.

• Energy Efficiency Analysis of Energy saving Control System for DLT-JY Series Special Profile Extruder

The following is the usage effect of our company after installing the DLT-JY series special profile extrusion machine energy-saving control system in a large light alloy enterprise in Kunshan.

Based on the above data, the annual arrangement of the enterprise is as follows: 11 months of work, equipment load of 85%, electricity cost of 0.8 yuan/kWh, which can save the enterprise an annual electricity cost of 160 * 0.85 * 24 * 26 * 11 * 0.305 * 0.8 ≈ 228000 yuan. From the above data, it can be seen that its direct economic benefits are objective.

The servo system developed by Zhufeng Electric has contributed to energy conservation and consumption reduction in major high energy consuming enterprises, especially in the non-ferrous metal and aluminum profile industries. It has also reduced the frequency of equipment maintenance and improved work efficiency.
