Injection molding machine

Injection molding machine is also known as injection molding machine or injection machine. It is the thermoplastic or thermosetting plastic using plastic molding mold to make plastic products of various shapes of the main molding equipment. The traditional injection molding machine is mainly hydraulic, with three-phase induction motor to control the system pressure through the overflow way to achieve the molding process. Yunsheng oil-electric servo system realizes the oil supply on demand through the double closed-loop of system pressure and flow, overcomes the high energy consumption caused by the high pressure overflow of the ordinary quantitative pump system, and effectively reduces the energy consumption during the operation of the injection molding machine.

Hollow blow molding machine

Hollow blow molding machine is a kind of plastic melting in the screw and quantitative extrusion into the mold cavity, and then through the injection of compressed air to melt the molten plastic cooling into the mold cavity shape plastic products. Blow molding machine is mainly divided into clamping system, feeding system and blowing system. The power of the clamping system is provided by the hydraulic system. In the traditional blowing bottle hydraulic system, the induction motor + quantitative pump system is used to provide the power source. The system has the effect of high pressure overflow during the operation of the blowing molding machine, so the use of the electro-hydraulic servo system can reduce the energy consumption. The feeding system is driven by the motor to rotate the screw to realize the feeding. The traditional three-phase asynchronous motor has low efficiency and low power factor, and the DC motor has high maintenance cost in the later period. The use of synchronous non-inductive motor can improve the motor efficiency and improve the stability of the feeding system.

Plastic extruder

Extruder belongs to one of the types of plastic machinery, also known as screw extruder. It is a mechanical equipment that relies on the pressure and shear force generated by the rotation of the screw to make the material can be plasticized fully and mixed evenly, and formed by the mouth die. At present, the power saving of extruder is mainly achieved by changing the motor power output with asynchronous frequency converter. In order to seek technological breakthrough and product innovation, some extruder industry customers have used permanent magnet synchronous motor + synchronous frequency converter to replace the power part of asynchronous motor + asynchronous frequency converter. After the test, permanent magnet motor can replace the traditional three-phase asynchronous motor, and the power saving rate can be more than 10%.

Oil pressing machine

Hydraulic press is mainly used in sheet metal stamping and stretching forming, non-metallic fields such as composite material forming, automotive interior parts of hot pressing forming. The process pressing process usually has no pressure down, pressure booster, return, ejection, top cylinder return, buffer cylinder return action, the working pressure and flow required by each stage is different. At present, the vast majority of the hydraulic system uses quantitative pumps, and the motor controls the output of the pump at the rated speed. In the production process, some only need very little flow (such as pressure holding) action will cause energy waste. Through the double closed-loop control of pressure and flow, Yunsheng oil-electric servo system fundamentally solves the above problems, and truly achieves the control of "how much to give". At the same time, accurate pressure and flow control can also improve the stability of the equipment and the consistency of the product.

CNC shearing and bending machine

The main working characteristic of the hydraulic system of shearing and bending equipment is that the vertical downward pressure is formed by two parallel working hydraulic cylinders to drive the mold on the bending beam to shear or bend the plate. The CNC hydraulic control system mainly controls the synchronous operation of the bending process and the positioning of the dead point of the hydraulic cylinder when the machine is working at full load. Yunsheng oil-electric servo system is to use permanent magnet synchronous motor and quantitative pump through the drive to change the speed to achieve the purpose of on-demand oil supply, reduce the vibration of opening and closing die, stabilize the production process, improve product quality and quantity, reduce mechanical failures, prolong the service life of the machine. At the same time, Yunsheng oil-electric servo system eliminates the high pressure overflow energy loss of the original system and greatly reduces the capacity loss in the process of machine operation.

Die casting machinery

Die casting machine is a kind of equipment that pours molten alloy liquid into the pressure chamber, fills the mold cavity at high speed under the action of high pressure, and makes the alloy liquid solidify under this pressure to form the casting. In the production process of die casting machine, the working speed and pressure of each process are different. The speed and pressure control is realized by the overflow valve to return the excess hydraulic oil to the tank, and the energy loss in this process can reach 25-80%. The energy loss of die casting machine is greatly reduced by the double closed loop of pressure and flow. At the same time, Yunsheng permanent magnet servo motor combined with die casting machine application conditions using oil cooling mode to reduce the motor temperature rise effectively reduce the motor failure rate.

Textile machinery

With the improvement of electromechanical integration, AC frequency conversion synchronous speed regulating system is widely used in the transmission control of textile machinery. Spinning is the last step in the spinning process. In the spinning process, yarn breaking is the key to affect product quality, yield and energy consumption. In the spinning process, the tension of small yarns is large, the tension of medium yarns is small and stable, and the tension of large yarns increases. The change of tension rules determines the distribution law of small yarns with the most broken ends, medium yarns with the least broken ends, and large yarns with increased broken ends. Yunsheng permanent magnet synchronous motor and its control system in the spinning process according to the small, medium and large yarn different periods, set different speeds, stable spinning tension to improve the speed of the spinning machine, to improve the purpose of production efficiency.

Hvac equipment

Fan pump HVAC equipment is widely used in all walks of life in national economy, it is a large energy consumption. The load of traditional HVAC equipment is mostly selected according to the demand for full load work, and most of the time in the actual application is not working at full load. Therefore, as long as the average speed of the equipment is reduced, the load power will decrease significantly, so as to achieve energy saving effect. The traditional three-phase asynchronous motor uses the direct starting mode, the motor speed is fixed, and the wind baffle and valve are used to adjust the air volume or flow, which causes great energy waste. Yunsheng permanent magnet synchronous motor machine drive, through the intelligent constant pressure control, change the speed of equipment, effectively reduce the energy consumption of equipment running. At the same time, the frequency conversion starting can reduce the impact on the power grid when the equipment starts, reduce the failure rate of the equipment, eliminate vibration and water hammer phenomenon, and extend the service life of the equipment.

Ball mill machine

The commonly used driving mode of ball mill is: the asynchronous motor drives the cylinder to rotate through the deceleration mechanism. Under the action of centrifugal force and friction force, the grinding body and the material rotate together with the cylinder. When it reaches a certain height, the material is thrown off and crushed by the impact and grinding effect of the grinding body. In order to solve the disadvantages of large machines and equipment, the low-speed and high-torque direct drive permanent magnet motor does not need the deceleration device, and the direct connection with the equipment effectively saves the space, improves the efficiency, reduces the equipment cost and maintenance cost, and its importance is becoming increasingly prominent. The combination of permanent magnet motor and inverter can provide a wide range of motor speed control, the system gets rid of the "fixed speed, fixed mode" situation. Large torque permanent magnet direct drive motor itself has played the role of power source and gearbox at the same time, making the system gearless, greatly reducing the operation and maintenance costs.
