Electric hoist bridge crane is a small light lifting equipment. Gourd with small size, light weight, simple operation, easy-to-use features such as for industrial and mining enterprises, storage terminals and other places.By electric hoist motor, drive mechanism and the composition of drum or sprocket can be used alone can also be assembled together with the car flying in the use of a crane beam, LH electric double-beam bridge crane hoist with the traditional double-beam bridge crane is the difference between electric hoist drum to replace the small car, motor. Reducers, brakes and other lifting devices. This article mainly deals with electric hoist bridge crane to do the main body of analysis and calculation, including the electric hoist lifting body, and the operation of car bodies.

Three crossflow (No.1-No.3) dryers were tested. Dyer No.1 contains two crossflow columns, each column consists of two drying sections, one turn-flow device and a cooling section, and with a grain column thickness in the upper drying section of 0.277m and 0.304m in the lower section. The dimensions of dryer No.1 are 6.517m×3.400m×13.482m. No.2 dryer is similar to No.1, but is smaller and has a lower capacity. No.3 is a cylindrical crossflow dryer with two drying sections, one turn-flow device and a cooling section.

The mixed-flow dryer (No.4) is composed of eight modular sections. Each module has dimensions of 1.8m×1.0m×0.8m. The tow bottom modules serve as cooling stage. Dryer No.5 consists of two mixed-flow drying towers in series, similar in design as dryer No.4.

Dryers No.6-No.10 are concurrent-/counter-flow dryers, consisting of two or more towers. The number in front of “-CCF” indicates the number of towers. Each tower has two counter-/concurrent-flow drying sections. The last tower, or part of the last tower, is used for cooling. The depth of the counter-/concurrent-flow beds is 0.6m, the cross-sectional area of each tower is 2.2m×2.2m. It should be noted that overseas CCF dryers do not have counter-flow drying stages, only a counter-flow cooling stage.

The steam dryer is a unique dryer widely used in grain depots in China. It consists of 3-6 indoor drying and cooling towers, and a boiler. Each tower contains in its upper section a series of steam pipes, and in its lower section a number of inlet/outlet air ducts. The grain is heated by conduction as it flow over the steam-heated pipes, and is subsequently treated with ambient or slightly-heated recycled drying-air. The steam pressure in the pipes is 2×105Pa--4×105Pa (130-140℃), the diameter of the pipes is 42-48mm, and the distance between pipes is 110-120mm. The grain retention time is long (4-6 hours for 10-point moisture removal) due to the relatively low grain temperature.

Sun drying is still the main method of grain drying in China. Almost every village or depot has a special area for the sun drying of grains. The grain is spread out in 5-10cm thin layer and is stirred occasionally. In Northeast China where the ambient temperature is very low when maize is harvested, sun drying is a very slow process.

三横(一号至三号)烘干设备进行了测试. 戴先生no.1包含两个横栏,每栏分为两部分干燥, 一转流器及冷却段, 与粮食柱厚度在上部干燥部分0.277m和0.304m在下游. 尺寸干燥器一号是6.517m×3.400m×13.482m. 二号烘干机相似一号,但规模较小,具有容量较低. 第三是横向圆筒烘干机烘干两部分,一部分是转流装置和冷却段. 混流式干燥机(四号)是由八个单元章节. 每个单元尺寸1.8×1.0×0.8米. 拖车底部模块作为冷却阶段. 干燥器no.5分为两个混流干燥塔系列,类似的设计作为烘干四号. 干衣no.6-no.10都是concurrent-/counter-flow烘干机,由两个或两个以上的弹孔. 数年前的"框架",表明了很多水塔. 每个塔有两个counter-/concurrent-flow晒路段. 最后塔,或部分上塔,是用于冷却. 有深度的counter-/concurrent-flow病床0.6m,横截面的每个塔有2.2m×2.2m. 应当指出,海外ccf干衣没有反流干燥阶段,只有一个反流冷却阶段. 蒸气烘干是一个独特的烘干机广泛用于粮库中. 它由3-6室内干燥,冷却水塔,一台锅炉. 每个塔载在其上部一系列的蒸汽管道, 而在其下游的一系列进/出水口风筒. 谷物的热传导,因为它流了蒸汽加热管, 并随后处理空气或微循环加热干燥的空气. 蒸汽压力管道2×105pa--4×105pa(130-140℃),直径较小的管材是42-48mm, 之间的距离和管道是110-120mm. 粮食停留时间很长(4-6小时,10点去湿)由于相对较低的粮食温度. 晾晒仍然是主要的方法谷物干燥中. 几乎每一个村或仓库具有特殊的地区,以供晾晒谷物. 粮食是分布在5-10cm薄层,偶尔搅拌. 在东北那里的气温很低,当玉米收割, 太阳晒是一个非常缓慢的过程

机械中什么叫做工艺 什么叫工序 什么是冲压 冷热冲压有何区别 轧钢是什么 用什么工具

工序
一个或一组工人在同一工作地对同一个或同时对几个工件所连续完成的那一部分工艺过程被称为工序。
例如，
一个工人在一台车床上完成车外圆、端面、空刀槽、螺纹、切断；
一组工人刮研一台机床的导轨；
一组工人对一批零件去毛刺。

生产和检验原材料、零部件、整机的具体阶段。
在生产过程中，直接改变原材料（或毛坯）形状、尺寸和性能，使之变为成品的过程，称为工艺过程。它是生产过程的主要部分。例如毛坯的铸造、锻造和焊接；改变材料性能的热处理；零件的机械加工等，都属于工艺过程。工艺过程又是由一个或若干个顺序排列的工序组成的。

工序是工艺过程的基本组成单位。所谓工序是指在一个工作地点，对一个或一组工件所连续完成的那部分工艺过程。构成一个工序的主要特点是不改变加工对象、设备和操作者，而且工序的内容是连续完成的。
冲压工艺性是指冲压件对工艺品的适应性，即所设计的冲压件在尺寸大小、尺寸精度与基准、结构形状等是否符合冲压加工的工艺要求。

冲压--是在室温下，利用安装在压力机上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。
冲压模具--在冷冲压加工中，将材料（金属或非金属）加工成零件（或半成品）的一种特殊工艺装备，称为冷冲压模具（俗称冷冲模）。
