电动推杆/工业电动推杆的发展概况

来源网址:

第一种:目前市场上统称为种重型D系列电动推杆,这种电动推杆是我国最早的电动推杆,它一般由电机,减速齿轮,丝杠螺母以及外接行程限位开关等组成,这种电动推杆开始在国内一般用在冶金行业最多,这种电动推杆的速度一般就是2种标准,改变速度一般靠加减速机或者变频,这种电动推杆的优点是:结实耐用,缺点是:形象有点差,速度单一,丝杠单一,精度低。95年以前发展基本处于停滞阶段。

第二种:目前市场上应用最多的轻型DL系列电动推杆,2000年左右随着国内经济的发展,随着国外先进产品的引进,高强度铝合金(不锈钢)系列电动推杆,这种电动推杆外形美观,速度的可选性也比较多,限位开关主要采用磁感应限位开关,客户在使用起来也比较方便,精度也大大提高,丝杠的的选择也可以根据客户的使用选择梯形齿丝杠与滚珠丝杠,这种电动推杆很快就得到了很多客户的青睐,当然仿制品也随之而来,产品的质量也由于厂家的不同而不同。

The electric push rod / industrial electric putter is currently used as a indispensable linear transmission machinery and equipment after nearly30years of development, gradually formed a system, at present market of electric putter roughly divided into the following 4:

The first: currently on the market are collectively referred to as the heavy D series electric putter, the electric push rod is China's first electric putter, it generally consists of a motor, a reduction gear, screw nut and the external limit switch and other components, the electric push rod began in China generally used in metallurgical industry is the most, the electric push rod speed is2 standard, change the speed reducer or general plus frequency, the electric push rod has the advantages of: strong and durable, the shortcoming is: image has a single speed, screw, single, low precision. 95 years development basically at a standstill phase.

Second : the market for most applications in the light of DL series electric putter, around 2000with the development of the domestic economy, with the introduction of foreign advanced products, high strength aluminum alloys(stainless steel)series electric putter, the electric push rod appearance, speed of the optional is more also, limit switch mainly uses the magnetic inductive limit switch, customers in the use is more convenient, accuracy is improved greatly, screw selection can also according to the customer's choice of trapezoidal toothed screw and ball screw, the electric push rod soon received a lot of customers, of course, imitation also followed, the quality of the product is also due to the different manufacturers.

Third: the electric push rod is also called servo electric cylinder, which is characterized by high speed, high precision, high frequency, on many occasions with the DL ball series electric putter with servo motor to replace.

Fourth: FD series of small electric push rod, the electric push rod adopts the direct current motor, small volume, thrust, mainly used in the not very frequent local, FD series electric putter is the biggest advantage of built-in limit switch, customers are very convenient to use, does not need to be additionally connected control circuit.
