Asynchronous servo die casting machine energy saving: First, what is asynchronous servo? A: injection molding machine is to use asynchronous servo direct drive induction vector drive motor, and a device having a feedback function. Features asynchronous servo technology is fast dynamic response, cost-effective, easy to install, failure does not affect the injection molding machine production and maintenance costs low. Second, the frequency energy, synchronous servo energy conservation, energy efficiency and the advantages and disadvantages of asynchronous servo variable pump energy analysis? A :( a) the advantages and disadvantages frequency energy is as follows: It has three main drawbacks: 1, while saving state, injection molding machine productivity will decline. 2, the system is unstable. 3, the saving rate is low. There are two advantages of frequency energy: 1, easy to install. 2, when the frequency Saver fails, does not affect the normal production of injection molding machines. (B) the advantages and disadvantages of synchronous servo is as follows: It has two main advantages: 1, while saving state, injection molding machine productivity increased slightly. 2, the saving rate. Disadvantages synchronous servo has three: one, the price is high. 2, the installation complexity. 3, synchronous servo fails, the injection molding machine is not working, you need downtime maintenance. Disadvantages (c) the advantages and disadvantages of variable displacement pump variable pump: 1, energy-saving rate. 2, a large noise. 3, life is short. 4, post-maintenance costs high. Advantages of variable pump: in the field of energy-saving injection molding machine has a place. The advantages and disadvantages (four) asynchronous servo: asynchronous servo integrates synchronous servo frequency energy and energy-saving technology to their strengths together to overcome their own shortcomings, the injection molding machine industry subversive revolutionary technology. Its main advantages are as follows: 1, it is possible to enhance the productivity of injection molding machines. 2, the saving rate. 3, easy to install 4, asynchronous servo saver fails, does not affect the injection molding machine to produce. 5, post-maintenance and low cost. The disadvantage is that in the promotion phase, fame is not big enough. Third, the saving rate is how to calculate A: saving rate per hour of electricity (not installed Saver) per unit time consumption - energy-saving (installation Saver) electricity consumption per unit of time] ÷ mains electricity per unit of time amount per unit of product × 100% saving rate = mains (not installed Saver) per unit of electricity consumption - energy-saving (installation of energy-saving [unit) per unit electricity] ÷ electricity consumption per unit of product × 100 % saving rate per unit of product using more accurate. Fourth, asynchronous servo-saving energy conservation can be achieved? A: The saving rate depends on the mold process parameters, velocity values ??(0 to 99) and energy relations mold process parameters maximum speed the higher the value the smaller the saving rate. If the mold speed values ??generally between 0 to 30, the saving rate can reach 70%; if the plastic injection mold and melt velocity values ??generally above 90%, and no net cooling time (complete melt glue on the open mode), and shot rubber and melt a long time, the saving rate is only about 25% can be achieved. Fifth, after the energy transformation will affect the production efficiency and product quality production equipment? Answer: not affect the production efficiency of the production equipment, it will not affect product quality. Reason: asynchronous servo power amplifier, it is possible to improve the productivity of the injection molding machine. Asynchronous servo regulating flow more smoothly, does not affect product quality. Six, equipment service life saving device used by the project A: 5 years will not overhaul; fan theory of life is three years; the theoretical life of the filter capacitor is three years, the board capacitance theoretical life is seven years; full maintenance Under the circumstances, the whole life can reach more than 10 years. Seven, installation time is how much? Installation will affect the normal operation of the production? A: The single motor injection molding machine installation time is about 2 hours; when you need to install the injection molding machine downtime. Eight, how to provide ongoing maintenance? A: labor costs, travel expenses and the cost of materials outside the warranty period of 18 months, the warranty period only charge. If you are leasing, extended warranty service terminated. Nine, energy and power sector projects if there is a conflict of interest? Answer: no. Electricity is a scarce resource, very supportive of saving the electricity sector, such as the establishment of China Southern Power Grid energy services company, specialize in EMC (share electricity mode) business. Ten, asynchronous servo saver fails, it will affect the normal production? Answer: no. Because asynchronous servo saver power-saving and non-energy-saving switch, when it fails, the switching to a non-power-saving state, the injection molding machine can continue production. And compared to synchronous servo, which is one of the main advantages of asynchronous servo. XI, asynchronous servo energy-saving technology is working at the time of the injection molding machine, which step of the production cycle to work? As the production cycle without cooling process, it has the power saving space? A: In every action has a space saving, space saving depends on the velocity values ??mold process parameters, the speed value is smaller, the higher the saving rate, the greater the speed value, the lower the saving rate. Focus melt and injection speed values ??and time, because melt and shot rubber is the largest part of consumption. No net cooling time (melt finish on a model), the same space-saving. Twelve, asynchronous servo-saving technology application? A: asynchronous servo-saving technology is mainly used for injection molding machines, die casting machine, shoe machine, aluminum extrusion machines, presses and other hydraulic machines, air compressors and other motor requires precise control of other energy-saving projects. XIII, has done or synchronous servo frequency transformation transformation of injection molding machines, can use asynchronous servo-saving technological transformation? A: The frequency transformation has been done, you can replace the use of asynchronous servo technology to achieve higher energy efficiency energy-saving effect, enhance productivity, improve the stability of the injection molding machine. Synchronous Servo saving effect is good, do not replace the asynchronous servo under normal circumstances.
