Is energy saving equipment for injection molding machines effective? How can injection molding machi

There is no doubt about this, it is absolutely valid.

But what we have to consider is, how does the injection molding machine achieve energy saving, and at the same time, will it have any impact on the injection molding machine? How much energy saving can be achieved in general, that is, how much value can be brought to you.

First of all, you should know that the biggest power consumption of injection molding machines is the pump, electric heating, and dryer, and possibly the cooling system. These places probably account for more than 80% of the total electrical capacity. And energy saving is mainly for these parts of the transformation.

Secondly, for the pump, if it is changed from quantitative and variable to servo, it can not only reduce the power consumption by more than 40%, but also improve the product quality, which is recognized by the industry. If the nano energy-saving electric heating ring is used for the gun barrel (heating part), it can also save 30%-70% of the electricity consumption, reduce the temperature of the plant, and improve the working environment of workers. The dryer can also be modified to save more than 20% of electricity consumption.

As for cooling, it may account for a relatively small proportion, but it can also save more than 20% of electricity after the transformation.

Effective is a yes because it's scientifically proven. But how much, and which brand to use, needs to go through a step of research. Try contacting Sinaider.

Injection molding machine is a typical periodic variable load equipment, a complete production cycle includes clamping, injection, melting, cooling, mold opening and other stages, for its hydraulic system, each stage of the pressure, flow matching is different, and the power of the oil pump motor is equipped according to the maximum load in its operation process, however, only the high-pressure clamping and furnace rubber section of the motor load in a production cycle of the injection molding machine is larger, and the motor load in other working stages is generally small, especially the load of the cooling process is almost zero. In the whole working process of the injection molding machine, the electric energy loss of the oil pump motor is serious, and the power utilization rate is only 30% 70%, so the power saving space is relatively large. The high-efficiency and energy-saving servo controller developed for the injection molding machine takes the flow and pressure signals of the injection molding machine as its own control signal to achieve soft start and stepless speed regulation, so as to achieve the output power of the motor and its load, which is completely consistent with the whole process of the injection molding machine, and achieves high efficiency and energy saving without affecting the production efficiency, and the power saving rate can reach more than 50% and 80%.

The servo motor installation process only takes dozens of minutes, and the servo motor installation does not need to change the original circuit of the injection molding machine, the operation is simple, and there is no impact on the original production process; After the installation and commissioning of the servo power-saving power saving is completed and the injection molding machine is running normally, you can start the power-saving effect test, first switch the inverter to the non-power-saving operation state, record the start and end time of the test and the reading of the watt-hour meter at the beginning and end of the test, calculate the hourly power consumption of the oil pump motor in the non-power-saving state, and then switch to the power-saving operation state, record the electricity consumption of the injection molding machine under the same conditions in the same way, calculate the hourly power consumption of the oil pump motor in the power-saving state, and then according to the formula: power-saving rate = [ (Electricity consumption in non-power-saving state Electricity consumption in power-saving state) Electricity consumption in non-power-saving state] 100% to find the power-saving rate. Therefore, after installing the inverter, you can immediately test the power-saving rate, determine the power-saving effect, and really know how much electricity is saved per hour and how much production cost is reduced.

The most straightforward and fast method.

Add a layer of thermal insulation to the barrel.

can play a significant role.

With the installation of power-saving equipment, the energy-saving rate is generally between 15% and 65%.

Electromagnetic heaters are energy efficient.

Energy-saving investment effect and return analysis: Take a plastic machine with an electric heating power of 10kw as an example, start it for 24 hours a day, and calculate it according to the actual working time of 10 hours a day (the working on-off time ratio of the general plastic electromechanical and electrical heating part is: the original electric heating ring (plate):).

Daily electricity consumption (10kw*10h=100kwh), monthly electricity consumption (100kwh*30=3000kwh); Transformed electromagnetic heater (calculated according to the minimum energy saving rate of 30%): daily electricity consumption (10kw*70%*10h=70kwh), monthly electricity consumption (70kwh*30=2100kwh); If the electricity cost is RMB, the monthly electricity saving fee is (3000KWH-2100KWH)*RMB KWH=720RMB; The cost of transformation is: 600 yuan kw * 10 kw = 6000 yuan; Cost Period:

6000 720 = months; It can be seen that for the injection molding machine of the electric tiger, the energy-saving effect of the electromagnetic heater is quite significant.

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.

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.
