What are the ways to save energy and electricity in injection molding machines?

Injection molding machine energy-saving and power-saving are: frequency conversion energy-saving transformation, servo energy-saving transformation, heating transformation, the beginning of frequency conversion energy-saving transformation is very popular, but it turns out that energy saving can not achieve the ideal effect, the most important thing is that the equipment is unstable after the transformation, it has been eliminated, and now servo energy-saving transformation has become a trend. The technology is very mature, not only can achieve energy saving effect, but also the modified machine is very stable.

Energy-saving transformation of professional injection molding machines.

Guangzhou Yunyan Electric, specializing in the servo energy-saving transformation of injection molding machines, providing energy-saving transformation solutions for injection molding machines, t: 020-38796180 The purpose of servo energy-saving transformation of injection molding machines: save energy, reduce costs, improve quality, and improve working conditions!

As one of the general equipment in the manufacturing industry, the air compressor can effectively help enterprises save production costs by doing a good job in energy saving. So, how to make the air compressor energy-saving? Zhongke Yujie will take you to take a look!

1. Liquid teaser leakage.

It is estimated that a small hole of 1mm, under a pressure of 7bar, has a leakage of about 1mm, check all the transmission pipe network and gas points, especially joints, valves, etc., and deal with the leakage points in time.

Second, pressure drop management.

Detect the pressure by setting up a pressure gauge through the pipeline section, check the pressure drop of each section of your section in detail, check the maintenance of the problematic pipe network section in time, the general air compressor outlet to the gas point, the pressure drop can not exceed 1bar, and the strict raw baby is not more than 10%, that is, the pressure drop of the cold and dry filter section is general. The factory tries to arrange the annular pipe network to balance the air pressure at each point.

3. Adjust the pressure matching of gas equipment.

Evaluate the pressure demand of the gas consuming equipment, and reduce the exhaust pressure of the air compressor as much as possible in the case of production. For every 1 bar reduction in the exhaust pressure of the air compressor, the energy saving is about 7%-10%.

Fourth, adjust the unreasonable use of gas.

According to data analysis, the electric energy utilization rate of the air compressor is only about 10%, and about 90% is converted into heat energy and lost. At the same time, the use of compressed air for routine cleaning should be resolutely eliminated.

Fifth, the use of centralized control mode.

If the number of air compressors is small, a frequency conversion air compressor can be used to regulate the pressure, and if the number is large, centralized linkage control can be used to avoid the rise of stepped exhaust pressure caused by the parameter setting of multiple air compressors.

6. Do a good job in equipment maintenance and cleaning.

Increase the heat dissipation effect of the air compressor, the exchange effect of water cooling, air cooling and other heat exchangers to keep the oil clean.

7. Waste heat of air compressor**.

**Hot water is generated from the heat of the air compressor oil system for use in other processes or auxiliary living facilities.

8. Renovation or replacement of drying system.

The waste heat of the air compressor is used for drying and dehydrating the compressed air with the waste heat of the new drying equipment, and the energy saving rate is more than 80%.

9. Energy-saving transformation of the system.

Zhongke Yujie intelligent air compressor power saver greatly reduces the starting current of the compressor through voltage regulation and soft start, so as to avoid the impact and damage caused by excessive starting current to the equipment when the compressor starts; According to the user's demand for compressed air, the motor power is accurately matched to avoid waste; At the same time, the pressure stability can also be obtained by using the gas equipment production process, which is very conducive to the control of product quality of the enterprise.

Servo motor.

Servo motor, also known as actuator motor, is used as an actuator in an automatic control system to convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.

First, the direct benefits of the servo transformation of the injection molding machine:

1. Energy saving: reduce unit energy consumption and raw material consumption, save energy and materials, save energy compared with the fixed pump, and save more than 10-30% more energy than the vector frequency conversion system (self-called servo system);

2. Improve the accuracy of the injection molding machine: the product weight and size repeatability are high, the fluctuation range is small, the product qualification rate is improved, and the raw materials are saved;

3. Improve production efficiency: high speed and high response speed increase the efficiency of the injection molding machine by up to 25%;

4. Super explosive power: 0-1500rpm acceleration time only takes 15ms, suitable for high-speed machine with screw fire rate of 0-400mm s.

There are dedicated energy-saving products for both the heating section and the motor.

The energy saving of the injection molding machine can be divided into two parts: one is the power part and the other is the heating part.

Power part of energy saving: most of the use of inverter, the way to save energy is to save the residual energy of the motor, for example, the actual power of the motor is 50hz, and you actually only need 30hz in production is enough to produce, those excess energy consumption is wasted, the inverter is to change the power output of the motor to achieve the effect of energy saving.

Energy saving in heating part: Most of the energy saving in heating part is energy saving by electromagnetic heaters, and the energy saving rate is about 30%-70% of that of the old resistance coil.

1.Compared with resistance heating, the electromagnetic heater has an additional layer of insulation, and the utilization rate of heat energy increases. 2.

Compared with resistance heating, the electromagnetic heater directly acts on the barrel heating, which reduces the heat transfer heat energy loss. 3.Compared to resistance heating, electromagnetic heaters heat up more than a quarter faster, reducing heating time.

4.Compared with resistance heating, the heating speed of electromagnetic heaters is faster, the production efficiency is improved, and the motor is saturated, so that it reduces the power loss caused by high power and low demand. The above four points are the reasons why Feiru electromagnetic heater can save energy by up to 30%-70% on the injection molding machine.

First, the energy saving of the injection molding machine can reduce unnecessary waste for you Second, the energy saving of the injection molding machine is more environmentally friendly

Third, the energy saving of injection molding machines can make workers healthier

Fourth, the products produced by the injection molding machine are not worse than those produced by ordinary injection molding machines, but the colors are more vivid!

Now it is a green country, and they are all advocating environmental protection, green Then we should also advocate and carry forward energy-saving things

The biggest benefit of energy saving in injection molding machines is energy saving and environmental protection.

A lot, the country's energy is saved, environmental pollution is reduced (coal power is used in some places in the north), the cost of the owners themselves is reduced, and so on.

Reduce energy consumption and reduce costs.

The use of three-crystal inverters in injection molding machines can achieve energy saving.

At the same time, the use of three-crystal inverter can make the injection molding machine oil pump motor achieve soft start, improve the power factor COS of the motor, and dynamically adjust the output power of the injection molding machine motor to achieve the purpose of energy saving.

For the enterprise itself: reduce costs and increase profits.

Nowadays, many manufacturers are saving energy by applying frequency converters to injection molding machines.

The following is the ** of the triple crystal inverter.

Stupid. Reduce costs. Boost your profits...

The injection molding machine is one of the main molding equipment for plastic products, and its work is to inject the plasticized molten state (i.e., viscous fluid) plastic into the closed mold cavity with the help of the thrust of the screw (or plunger), and obtain the process of the product after curing and shaping.

Generally, the consumption of injection molding machine is mainly because in the process of process, when it is necessary to change the load flow and pressure, the valve is used to adjust, and the input power does not change much, and a large amount of energy is lost on the valve in the form of pressure difference, resulting in overflow.

The energy-saving principle of the injection molding machine is: according to the current working state of the injection molding machine, such as mold locking, injection, melting, mold opening, thimble and other stages, as well as the setting requirements of pressure and speed, the speed of the oil pump is automatically adjusted, and the oil supply of the oil pump is adjusted, so that the actual oil supply of the oil pump and the actual load flow of the injection molding machine can be consistent in any working stage, so that the energy consumption of the motor in the entire changing load range reaches the required minimum, completely eliminates the overflow phenomenon, and ensures the smooth and accurate operation of the motor.

Buy one that is controlled by a servo motor to save power. However, the motor will be scrapped after five years, and it will be much more expensive.

There is a Guangzhou energy source that specializes in doing these, you can go to Jitri Plastic Machinery Network for reference.

It is mainly the transformation of asynchronous motor frequency conversion and electromagnetic heating to replace resistance wire heating.
