Frequency Conversion Technology of Cargo Elevator

Cargo elevator is a large power consumption, each cargo elevator – Escalator Company at least equivalent to 10 air conditioners, but also produce electromagnetic waves, noise interference. Therefore, the government and manufacturers will jointly implement the application of energy-saving technologies. Such as “maglev” -like operation Permanent magnet synchronous motor drive technology works similar to the maglev train, through the magnetic field cutting to produce traction, drive the elevator car up and down.

In the past, the traditional cargo elevator running through the gear transmission, inevitably have energy loss, but also the need to use lubricants, worm gear reducer will make room noise, and now, permanent magnet synchronous motor drive system efficiency will be increased by more than 30%, and reduced power consumption. Take an ordinary elevator with a load of 1050 kg as an example. If the daily operation is 16 hours and the working condition is averagely 40% load, each permanent magnet synchronous cargo elevator can save 9000 kWh per year compared with the traditional products. It is understood that Shanghai Mitsubishi Elevator currently has more than 30% of the products using this technology.

Electric motor and its load to save energy there are two main ways: First, improve the motor or load operating efficiency, such as fan, pump speed is to improve the efficiency of the load operation as the goal of energy-saving measures, another example cargo elevator drive inverter speed to replace the traditional AC induction motor speed regulator is to improve the efficiency of the motor as the goal of energy-saving measures. The second is the motor has been converted to the load on the mechanical energy inverse conversion into electrical energy regeneration and utilization, so that the motor and the load in the unit time consumption of the grid power down, so as to achieve the purpose of saving. Active energy feedback device is the second type of energy-saving devices typical.

As we all know, motor drag load rotary motion that is equipped with mechanical kinetic energy, if the motor pulled up, the next movement of the load (such as elevators, cranes, reservoir gates, etc.) and have a bit of energy. When the motor drives the load to decelerate, the mechanical kinetic energy will be released. When the potential energy load decreases (the bit energy can be reduced), the mechanical position energy will also be released. If the two mechanical energy can be effectively converted into Regeneration and utilization of electricity and energy can achieve the purpose of saving electricity.

  1. The American Sewing Guild: Artists in Fabric

    They come from all walks of life, from all over the area, including Apollo Beach, Ruskin, Riverview, Sun City Center and Brandon. They unite to pursue one common obsession: Functional Fabrics.
    Their projects range from making adult garments, fashion pieces, purses, doll clothes, pillowcases, baby clothes, woolly dolls and infant blankets to art quilts honoring veteran soldiers.
    Who are they? They are the talented women of The American Sewing Guild, a national non-profit organization dedicated to supporting sewing enthusiasts all over the U.S.
    With more than 125 chapters and nearly 1,000 neighborhood groups that sponsor sewing activities in local communities, ASG has something to offer anyone with a yen for needle and thread.
    Standing, from left: Dorothy Sparks, Martha Collins. Seated: Cindy Falck and Delores Lines.
    “It’s a lifelong interest that we love to share,” said Martha Collins of MiraBay, president of the ASG local chapter, East Bay/Brandon, which, with a current membership of 130, is a spinoff from the growing Tampa Bay chapter.
    “Our members love the camaraderie and friendship they get through ASG,” she said. “There’s just nothing else like it.”
    “We’re like a bunch of little girls all grown up,” said Cindy Falck of Apollo Beach, who loves sewing doll and baby clothes. “I just recently had the joy of making an Easter dress for my new grandbaby, and nothing could have made me happier.”
    Dorothy Sparks, a winter resident of Kings Point in Sun City Center, agreed. “Many of us started out in 4-H, and now we’re like grown-up 4-H-ers,” she said. She loves the sense of community that being a member of ASG gives her. “I started sewing as a need,” she said, “because I was short and could never find clothes to fit me. Now it’s no longer a need, it’s my passion.”
    ASG chapters come in all sizes — larger chapters often sponsor quarterly chapterwide special events that may feature local or national speakers, member fashion shows or specialty workshops.
    Smaller chapters may form because they share a specific interest, like quilting or doll clothes.
