What is the effect of the energy saving transformation of the servo of the injection molding machine

Look at what equipment, if it is the injection molding machine servo transformation energy saving rate and the frequency of production of products is related, if it is a large plastic product, the injection molding machine working frequency is low, the servo effect is about 30%. If it is a small product, the frequency is relatively high, and the energy saving rate is not obvious.

It is best not to do the transformed servo, and the failure rate is relatively high.

It is recommended to use an over-efficiency inverter, which can work at full load without affecting the output on the basis of retaining the advantages of the inverter, saving 30% of energy

How is the effect of the servo energy-saving transformation of the injection molding machine, I don't know how many tons yours are, and I will give you a 1250-ton energy-saving data after the transformation:

Servo: 1250 tons.

Calculation of energy saving and electricity saving rate of power part:

The high energy consumption time of the injection molding machine is about.

Actual production cycle.

The low power consumption time is about 130s

Process power saving rate = (130

The energy saving rate is 75%.

Analysis of energy-saving benefits of servo injection molding machine.

Haitian HTF1250*2 injection molding machine: the quantitative oil pump is a double-blade pump (two pumps), and the motor is a 55KW asynchronous motor (two sets).

Servo transformation: gear pump (three pumps) + servo motor (three) + servo controller (three) ** power consumption per hour = 55kwh

Hourly power saving = **Hourly power consumption * energy saving rate = 55 * 75% = average energy saving rate per kWh = yuan khw

The number of effective days of equipment operation per year = 330 days per year (deducting equipment maintenance and power outage time) and annual cost savings = 330 * 24 * yuan year.

After the servo transformation, it can save about 10,000 yuan a year.

The above is provided by Keyi Thermal Technology.

There are only two ways to save energy and transform the servo of the injection molding machine, the synchronous servo and the asynchronous servo, the synchronous servo energy saving rate is higher, but at the same time, the cost return time is relatively long. Asynchronous servo is slightly lower, not much lower, ** is relatively low, before the original transformation of the best to find some domestic energy-saving enterprises to test your company's machine, energy-saving effect can be specific large-scale implementation of the project.

Our company is specialized in energy-saving transformation of injection molding machines, injection molding machines of more than 400t, the power-saving rate is more than 30%, I am talking about servo transformation.

The energy-saving space of the servo transformation of the injection molding machine mainly depends on the proportion of the idle and multi-rotation time of the motor in the production process of the injection molding machine in the entire production process. (Empty ** means that the motor does not do work, and the production process can be completed; Many**

In the process, the rated speed of the motor is assumed to be 1600rpm, and at this time, only 600rpm is actually needed to complete the process, so the extra 900rpm can save electric energy. ）

When the machine stops running, or when the power consumption is very low, the energy-saving space will not be created out of thin air. The energy-saving rate of the servo energy-saving transformation of the injection molding machine is generally not less than 30%, and the maximum may reach 75%, of course, it all depends on the specific situation of the injection molding machine.

Mainly look at the motor, reactive power running time to determine the cost savings. Generally speaking, products with a longer production cycle save more costs. The main part of the savings is the time it takes for the product to cool down.
