Automatic Handy Dryer is an electric machine found in public bathrooms. Hand dryer works automatically using an infrared sensor. Hand washing is an important part of hygiene, so an effective method of drying the hands is necessary. Automatic Hand dryer is made of white plastic, wall mounted in public washroom.
1. Spiral pump chute (pump housing) installation of chute and pump blade gap size, a great impact on the efficiency of the pump. Therefore, the installation accuracy is very high. Grooves can be constructed of prefabricated concrete blocks. The practice is: the chute prefabricated into 1m long block, placed in advance on the basis of the chute, and then install the screw pump, block by block and adjust the gap between the pump, the last grouting fixed block. Prefabricated blocks slightly larger groove spiral groove diameter. After the screw pump is installed in place, slowly turn the screw and scrape the excess mortar out of the groove. After the screw blade is removed, the powder is flattened and cured. After the mortar is solidified, the pump casing naturally forms. In the special requirements, but also the production of steel chute. It is best to make the gap between the blades and the pump casing, maintaining about lmm. 2. Motor Installation As the screw speed is low, can not be directly driven by the motor, you must take measures to slow down. In the design of transmission parts, should consider a single layout or more side by side layout of the space problem. Single layout. The entire pump on an axis, the flange so that the motor directly on the gearbox body. It is characterized by compact structure, small footprint, but this connection, reduction gear larger. The motor is connected to the gearbox via a V-belt. This arrangement of the length of the motor room will be increased, such as several pumps arranged side by side, then a large area. The motor is mounted above the gear box, the middle with a V-belt connection, the layout is compact, suitable for the pump machine number of occasions. One of the common features of the above three arrangements is that the gearbox and the motor should be tilted so that all the gears in the gearbox can not be immersed in the oil. The motor bearing is also easy to wear and the installation concentricity is high. To this end, can also be taken to change the housing and gearbox entry and exit axis angle approach, the gear box and the motor are kept horizontal position. Under normal circumstances, the motor and gear box are used V-belt drive, because this way, in addition to make the gear smaller, but also flexible layout, but also help to start and enhance the solid object.
