貴州電梯">電梯的分類方式

Classification of elevators

貴州電梯

電梯是指動力驅動,利用沿剛性導軌運行的箱體或者沿固定線路運行的梯級(踏步),進行升降或者平行運送人、貨物的機電設備,包括載人(貨)電梯、自動扶梯、自動人行道等。那麽電梯的分類方式有哪些?貴州電梯廠家為您詳細介紹一下。

Elevator refers to the power drive, the use of rigid box running box or along the fixed line running step (step), to lift or parallel transport of human and cargo mechanical and electrical equipment, including manned (cargo) elevator, escalator, automatic sidewalk and so on. So what are the classifications of elevators? Guizhou elevator manufacturers give you a detailed introduction.


電梯作為一種通用垂直運輸機械,被廣泛用於不同的場合,其控製、拖動、驅動方式也多種多樣,因此電梯的分類方法也有下列幾種。

As a general vertical transport machinery, elevators are widely used in different occasions. Their control, drag and drive modes are varied. Therefore, there are several classifications of elevators.


一、普通分類

One, general classification

1. 乘客電梯。

1. passenger elevator.

2. 載貨電梯。

2. cargo elevator.

3.客貨兩用電梯。

3. passenger and freight dual use elevator.

3. 病床電梯。

3. sickbed elevator.

5.雜物電梯。

5. clutter elevator.


這是一種常用的分類方法,但由於電梯有一定的通用性,所以按用途分類在使用中用得較多。但實際標準不很明確。其他特種用途的電梯還有汽車電梯,船舶電梯等。

This is a common classification method, but because the elevator has a certain generality, so the use of classification is more used in the use. But the actual standard is not very clear. Other special use elevators also have car elevators, ship elevators and so on.


二、按速度分類

Two. Classification by speed

電梯的額定運行速度正在逐步提高,因此按速度分類的國家標準正待頒布。目前的習慣劃分為:

The rated operating speed of the elevator is gradually increasing, so the national standard which is classified according to speed is being issued. The current habits are divided into:

1.低速電梯

1. low speed elevator

這種電梯額定速度≤0.75m/s。

This elevator rated speed of more than 0.75m / s.

2.中速電梯

2. medium speed elevator

這種電梯額定速度≥1m/s~2.5m/s。

This elevator rated speed is greater than or equal to 1m / S ~ 2.5m / s.

3.高速電梯

3. high speed elevator

這種電梯額定速度>2.5m/s~4m/s。

The rated speed of this kind of elevator is > 2.5m / S ~ 4m / S.

4.超高速電梯

4. super high speed elevator

這種電梯額定速度>4m/s。

The rated speed of this kind of elevator is > 4m / S.


三、按拖動電動機類型分類

Three. Classification according to the type of dragging motor

1.交流電梯

1. AC elevator

采用交流電動機拖動的電梯。其中又可分為單、雙速拖動,采用改變電動機極對數的方法調速。調壓拖動,通過改變電動機電源電壓的方法調速。調頻調壓拖動,采取同時改變電動機電源電壓和頻率的方法調速。

An elevator with AC motor dragging. It can also be divided into single and double speed dragging, using the method of changing the pole logarithm of the motor to adjust speed. Adjust the voltage and drag by changing the power supply voltage of the motor. FM voltage regulation and drag, and change the power supply voltage and frequency of the motor at the same time.

2.直流電梯

2. direct current elevator

這是一種采用直流電動機拖動的電梯。由於其調速方便,加減速特性好,曾被廣泛采用隨著電子技術的發展,直流拖動正被節省能源的交流調速拖動代替。

This is a kind of elevator which is dragged by a DC motor. Because of its convenient speed regulation and good acceleration and deceleration characteristics, it has been widely used. With the development of electronic technology, DC drive is being replaced by AC speed regulation drive with energy saving.


四、按驅動方式分類

Four. Classification by drive

1.鋼絲繩驅動式電梯

1. wire rope driven elevator

它可分成兩種不同的型式,一種是被廣泛采用的摩擦曳引式。另一種是卷筒強製式。前一種安全性和可靠性都較好,後一種的缺點較多,已很少采用。

It can be divided into two different types, one is widely used in friction traction. The other is the drum force. The former is safe and reliable, and the latter has many shortcomings and has been rarely used.

2.液壓驅動式電梯

2 hydraulic drive type elevator

這種驅動式電梯曆史較長,它可分為柱塞直頂式和柱塞側置式。優點是機房設置部位較為靈活,運行平穩,采用直頂式時不用轎廂安全鉗及底坑地麵的強度可大大減小,頂層高度限製較寬。但其工作高度受柱塞長度限製,運行高度較低。在采用液壓油作為工作介質時,還須充分考慮防火安全的要求。

This type of driving elevator has a long history, and it can be divided into plunger straight top and plunger side placement. The advantage is that the locations of the engine room is flexible and stable. When using the straight top type, the strength of the car safety clamp and the bottom pit can be greatly reduced, and the height of the top floor is limited. But the work height is limited by the length of the plunger, and the running height is low. When the hydraulic oil is used as the working medium, the requirements of fire safety must be taken into full consideration.

3.齒輪齒條驅動式電梯

3. gear and rack driven elevator

它通過兩對齒輪齒條的齧合來運行;運行振動、噪聲較大。這種型式一般不需設置機房,由轎廂自備動力機構,控製簡單,適用於流動性較大的建築工地。目前已劃入建築升降機類。

It runs through the meshing of two pairs of gear and rack; it operates in vibration and noise. In general, it does not need to set up the machine room. It is equipped with a car's own power mechanism. It is easy to control and is suitable for the construction site with large fluidity. At present, it has been classified as building elevator.

4.鏈條鏈輪驅動式電梯

4. chain sprocket driven elevator

這是一種強製驅動型式,因鏈條自重較大,所以提升高度不能過高,運行速度也因鏈條鏈輪傳動性能局限而較低。但它在用於企業升降物料的作業中,有著傳動可靠,維護方便,堅固耐用的優點。

This is a type of forced driving. Because the weight of the chain is large, the lifting height can not be too high, and the running speed is also limited due to the limited performance of the chain sprocket transmission. But it has the advantages of reliable transmission, convenient maintenance and durable and durable in the operation of the lifting material for enterprises.

其他驅動方式還有氣壓式,直線電機直接驅動,螺旋驅動等。

Other driving modes are air pressure, direct drive of linear motor, spiral drive and so on.


五、按控製方式分類

Five. Classification by control

目前貴州電梯技術的發展使電梯控製日趨完善,操作趨於簡單,功能趨於多樣,控製方式正向廣泛應用微電子新技術的方向發展。目前常見的控製方式有:微機集選控製(按鈕操縱);門微機並聯、梯群控製(按鈕操縱);繼電器信號控製和手柄控製(手柄或按鈕操縱)。

At present, the development of Guizhou elevator technology makes elevator control more and more perfect. Operation tends to be simple and function tends to be diverse. Control mode is developing widely in the direction of new technology of microelectronics. At present, the common control methods are microcomputer centralized control (button operation), gate microcomputer parallel connection, ladder group control (button operation), relay signal control and handle control (handle or button operation).
