vertical rubber injection machine power saving how do we do?
There is a lot of content related to "power rationing" on the Internet. Industry insiders said that there are many reasons behind the power shortage, such as insufficient supply and increased demand. For example, under the comprehensive influence of the rapid development of service industry, high-tech and machinery manufacturing industry, winter cold wave, high temperature in summer, rapid popularization of electric energy substitution, and the transformation and upgrading of urban and rural power grids to release electricity demand, the vertical rubber injection machine used in China's plastic industry adopts proportional valve control technology and on-off valve control technology. The hydraulic power part of vertical rubber injection machine adopts the hydraulic system of ordinary three-phase asynchronous motor quantitative pump. The molding process of the product is generally divided into several stages, such as locking, injection, melting, holding pressure, cooling, opening and discharging. How to use vertical rubber injection machine to save electricity?
1. vertical rubber injection machine proportional valve control oil circuit features:
After the oil pump motor runs, it runs at full speed and high load, and then the proportional valve sets the pressure and flow required for each level. However, in a production cycle of an injection molding machine, only the motor load in the high-pressure mold clamping and melting stage is larger, while the motor load in other stages is generally smaller. In other stages, the oil pump motor provides a constant flow at a constant speed, and the excess hydraulic oil flows back through the overflow valve. Generate unnecessary waste.
2. switch valve control oil circuit features:
The power of the oil pump motor is equipped according to the large load during its operation. After the oil pump motor is running, the pressure and flow are not set. During the work of each stage of mold locking, glue injection, glue melting, pressure maintaining, cooling and mold opening, the corresponding direction switch valve in the oil circuit is opened, and the overflow valve works at full flow. When cooling and discharging, the directional on-off valve is closed, and the overflow valve is opened, all returning, causing waste.
Vertical rubber injection machine energy saving analysis;
In the process of cooling and discharging, the load of hydraulic drive equipment represented by vertical rubber injection machine is almost zero, and the cooling and discharging time accounts for 30-60% of the whole cycle. According to the previous work experience, in the injection molding machine. The energy loss caused by cooling and discharge overflow is as high as 30%-65%. The power consumption of the oil pump motor of the injection molding machine accounts for 60%-75% of the total power consumption of the equipment, which has the potential to save energy. Energy-saving low-carbon life itself should become a habit of people's lives. No matter what the next power supply situation is, we should implement the awareness of energy saving and emission reduction into our daily life. From a macro perspective, green low-carbon is the only way for sustainable development. Striving for the peak of carbon dioxide emissions in 2030 is not only China's commitment to the world, but also the endogenous need of China's economic transformation.
