In the mechanical industry standard JB- Technical Conditions for Elevators was released， which was an early technical standard for the elevator industry in China.
8Signal elevator， which is a highly automated elevator with a driver. In addition to having automatic leveling and automatic door opening functions，It also has functions such as car command registration， floor call registration， forward stopping，Small domestic elevator and automatic reversing.
xQinghaiSpecial attention should be paid to the civil deviation of high-rise buildings. The vertical deviation of the shaft on one side of the hall door should be ensured to be within ~+mm. For a long time，peasStage main lifting platformManagement System Research various types of household elevators， villa elevators， household elevator manufacturers， and small household elevators are provided to individuals and enterprises nationwide for door-to-door sales， on-site settlement， and honest operation. Offices are set up in various regions， and long-term cooperation is possible. The vertical deviation of the other three shafts should be ensured to be within ~+mm.
After the elevator arrives and opens the door， first let the personnel inside the car exit the elevator， and then the caller enters the elevator car. After entering the car，Small domestic elevator press the corresponding numerical button on the control panel inside the car according to the floor you need to reach. Similarly， as long as the button light is on， it indicates that your selected layer has been recorded; At this point， there is no need to perform any other operations， just wait for the elevator to arrive at your destination floor and stop.
LChebok sareIn ， the annual production of elevators in Chinas elevator industry exceeded units for the first time. The third wave of development in Chinas elevator industry since the reform and opening up is rising. The first occurrence occurred from to ， and the second occurrence occurred from to . The milestones for the annual production growth of elevators in China are shown in the table below.
WiLow speed elevator， often referring to an elevator with a speed below m/s.
Screw elevator， which processes the plunger of a straight top elevator into a rectangular thread， thereby causing the screw to lift the elevator car up or down.
The vertical elevator has a complete protective device，Small domestic elevator which is maintained normally and will not suddenly fall.
xProblem at the entrance of the brick concrete structure hall: If there is only a small section of lintel above the entrance， which cannot meet the installation requirements of the elevator hall door，peasStage main lifting platformManagement System Research users must make two steel splints above the entrance. The position and size of the clamp plate are determined based on the selected door machine model.
MEven if the steel cable is completely broken and falls at extreme speed， there are still three tracks left; Amulet”
KWelcome calls The driving method is an alternating current elevator， which uses an alternating current motor as the driving force. According to the dragging method， it can be further divided into AC single speed， AC double speed， AC voltage regulation speed regulation， AC variable voltage frequency regulation speed regulation etc.
jATheoretical transportation capacity. It is the main parameter of escalators and moving sidewalks， referring to the theoretical number of people transported per hour.
Electric traction system: The function of electric traction system is to provide power and implement elevator speed. The electric traction system consists of a traction motor，Home elevator, villa home elevator, small home elevator, home elevator brand - home elevator manufacturer a power supply system， a motor speed control device， etc.
Without a driver when passengers enter the elevator car and press the desired floor button on the control panel， the elevator automatically runs to the destination floor. This type of elevator generally has a centralized selection function.
Create brilliancenIn the event of a fire， fire elevators are used to transport firefighters， passengers， and fire equipment in large cold storage or refrigeration workshops， transporting frozen goods. However， they need to meet the sealing requirements of door leaves， guide rails and other moving parts. They are specialized in selling home elevators， villa home elevators， and home elevator manufacturers. Small home elevators have stable， safe， reliable， and can achieve maintenance free performance， and their technical level has reached the domestic level， Meet the advanced level of international similar products and immersion requirements
NTechnical performance that needs to be emphasized& Flash; Reliability， progressiveness and comfort The so-called reliability refers to the ability of the elevator system to maintain the specified function within the specified time. Our requirement for elevator reliability is to minimize malfunctions during operation time and make it easy to eliminate them once they occur. This requires us to have a high level of reliability in our selection. We specialize in selling various types of products such as home elevators， villa home elevators， home elevator manufacturers， and small home elevators， which are well sold both domestically and internationally. Our equipment has a long service life! The product wire product industry is leading， welcome to inquire. The elevator configuration is good， and fortunately， there is a dedicated maintenance team in the local area.The progressiveness of elevator is mainly reflected in the drive and technology. The frequency modulation voltage regulation speed regulation technology (VVVF) is now the main energy-saving and drive technology. The microcomputer system realizes intelligence for elevators， with low failure rate， high reliability， and strong anti-interference ability in use.
DC elevator， an elevator that uses a DC motor as the driving force. The rated speed of this type of elevator is generally above m/s.
uQinghaiIn November ， the book Elevator translated by Xi Xiaosen et al. was published by China Construction Industry Press， and was written by Takeo Kimura et al. in Japan. This is one of the early elevator professional books in China.
lEIn the early days of the elevator， steam engine and internal combustion engine were used as power to directly drive the elevator， which has basically disappeared.
The basic requirements for an elevator can be determined based on the type and main parameters of the elevator.
