Use of low electromagnetic interference type micro-pump

For the use of DC brush motor micro-pump, micro-vacuum pump, pumping two pumping air, the motor interference problem is bound to exist. As the motor between the brush and commutator high-frequency conduction, disconnect, go back and forth, will produce a lot of clutter in the circuit. The amplitude of these clutters is high, usually several times the rated voltage, and varies in amplitude and frequency. These clutters "contaminate" the entire power supply by entering the circuit by connecting the motor's power cord. If the power supply is still supplying power to the control circuit, it is not uncommon for many electronic components (such as microcontrollers, LCD screens, etc.) to malfunction due to the impact of these clutter up to several tens of volts (40-90 volts, for example). Practice shows that there is a random instrument failure time, and the failure may not be the same each time, so find the reasons are often complicated. Low interference pump is developed to solve this problem, the product design and production also take into account due to the interference caused by the magnetic field space. After many years of experiments and feedbacks, it has been found that the disturbance is mainly caused by the pollution of the power supply by the motor. At present, no phenomenon has been found that the low-interference micro-pump interferes with other components through the effect of the space magnetic field. Such as miniature vacuum pump VAA series, PK series, high vacuum VBH series, VCH series can be made into a low electromagnetic interference type. Low interference micropump generated by the clutter amplitude are below 400 millivolts, the basic can be more than 99% of the clutter removed, over the years did not affect the normal operation of the microcontroller and the liquid crystal display. After the determination of the clutter amplitude of imported products due to different manufacturers generally between 200 millivolts to 3 volts. If you need a miniature vacuum pump and miniature air pump, suction pump dual function, such as FM series, FAA series, PCF series, but also can be customized low electromagnetic interference. Reminded: A large number of practices show that interference problems lead to abnormal time of the instrument is random, sometimes no, not easy to detect, to be extra careful. Therefore, it is recommended in the above applications, it is best to use low electromagnetic interference models (individual series currently can not be customized low-noise).

Automatic Door Kits

Our automatic door kits include 1 motor+gear reducer, 1 belt,7 meter, 1 idle pulley, Microprocessor, 4 sets of carriage blue wheels, 2 sets of floor guides,2pcs remote control, 2 sets belt clamp mounting brackets, 1 power supply harness and cable connectors, 2 locator, Aluminum track whose length is 2.08 meter, 3 meter, or 4 meter.

We are a manufacturer of automatic door openers that are designed to provide people convenience. Automatic Door Systems` drive to provide that level of service is but one of the reasons why automatic doors are becoming more and more popular. Our Automatic Sliding Door systems are modern, space-saving and elegant.

Automatic sliding doors have many basic functions some of which include: automatic mode with full opening width and/or reduced opening width, and exit only for traffic control. The opening of automatic doors can also be adjustable to make the opening width smaller or larger. Important safety functions such as safety sensors prevent the door from shutting if persons or objects are in the detection zone. If the door leaves are inhibited when closing, they are immediately re-opened or if the door leaves are hindered when opening, they are immediately stopped by a safety automatic reversing mechanism.

Our most popular sliding automatic door. Think of this as the go-to door for everyday automation needs. All components fully tested and pre-assembled at factory for fast, trouble-free installation.

Applications: Retail, healthcare, airports, hospitality, clean rooms. Shenzhen Hongfa Automatic Door Co.,Ltd rated door is designed, test and certified to meet your environment needs. automatic slide doors for industrial, commercial, healthcare, and retail use. You will find our automatic sliding doors throughout in a wide variety of locations, including: Hospitals, Airports, Retail centers, Pharmacies, Hotels, Grocery stores, Hardware stores, Sporting goods stores, and more.

Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.

The control device of sliding automatic door contains basic function and extensional function, automatic operation / hold-open/closed/half-open to meet customer needs. Electric sliding door controller has multiple interfaces for complete access control systems for keeping your life and property more safety. Such as: safety beam photocell, electric locks, sensor etc. Its drive devices adopts European technology to integrate motor with gear box, which offers strong driving and reliable operation and increased power output , it can adapt to a large door.

Providing strength, beauty, and technology all in one package, Hongfa's line of automatic sliding doors provides entrance solutions for practically any application. An exclusive feature is Hongfa's sound-dampening track reducing operational noise to a mere whisper and stops vibration resonance that can be transferred to the building structures.
