The abstract
喷雾泵站是采煤工作面的重要设备,在减小煤尘与瓦斯的危险和改善工作面的环境上起着重要的作用.
water pump station is an important equipment in the coal face.It plays an important role in redusing the danger of dust and gas concentrations.
喷雾泵站主要应用于采煤机的喷雾除尘,是采煤工作面喷雾系统的主要组成部分.
water pump station is mainly used in the mist spray and aspirating of coal cutter.
It is a main part of the aspirating system of the coal face.
喷雾泵主要由由电动机,减速器,曲轴,连杆,十字头,柱塞,泵体组成.设计的任务主要是对喷雾泵进行设计并进行必要的校核.
water pump is composed of motor,speed reducer ,crankshaft,connecting bar,crosshead,piston,pump body mostly.The main task of design is designing water pump and make the necessary intensity checking.
本文首先介绍了喷雾泵的结构和特点,然后根据压力与流量的要求选择电动机和曲轴的转速,进而对减速器,曲柄连杆机构,泵体进行设计并且对各个部件进行强度校核.
This paper first introduced the structure and characteristics of the water pump,and then choose the motor and the speed of the crankshaft on the basis of filling the pressure and flux requirement and the choice of motor revolutions of the crankshaft,then design the speed reducer ,connecting rod,pump body and then check intensity of every part.
设计的内容主要有方案的选定,减速器的设计,泵的结构形式的选择,泵体的设计,曲柄连杆机构的设计,十字头的设计.
The main content of the is selecting programme,the design of the speed reducer,the selection of structure of the pump selection,the design of the pump body,and the design of the connecting rod,the design of the crosshead.
该喷雾泵结构紧凑,占地面积小,符合采煤工作面的要求.
The structure of the water pump is compact ,and the water pump covers small area.It accord with the need of the coalface.

专业词汇应该没错，关键是语法上有没有错误？

我的意见哈~
喷雾泵站是采煤工作面的重要设备,在减小煤尘与瓦斯的危险和改善工作面的环境上起着重要的作用.
water pump station is an important equipment in the coal face.It plays an important role in redusing the danger of dust and gas concentrations.
*漏译了"改善工作面的环境"
water pump station is an important equipment in the coal face.It plays an important role not only in redusing the danger of dust and gas concentrations but also in improving the environment of the working surface.

喷雾泵站主要应用于采煤机的喷雾除尘,是采煤工作面喷雾系统的主要组成部分.
water pump station is mainly used in the mist spray and aspirating of coal cutter.
It is a main part of the aspirating system of the coal face.
*技术,设备的应用有更准确的词apply.还有就是前后用词应避免重复
water pump station is mainly applied in the mist spray and aspirating of coal cutter.It constitutes the vital part of the whole aspirating system of the coal face.

喷雾泵主要由由电动机,减速器,曲轴,连杆,十字头,柱塞,泵体组成.设计的任务主要是对喷雾泵进行设计并进行必要的校核.
water pump is composed of motor, speed reducer ,crankshaft, connecting bar, crosshead, piston, pump body mostly. The main task of design is designing water pump and make the necessary intensity checking.
*一系列词作同等成分,后面应用and.再说compose后面也不能少.前后design在汉语中都是语病,你认为正确可以不改.进行时的用法也似不妥.make the necessary intensity checking的主语不当,句子逻辑关系不明.
water pump is composed of motor, speed reducer ,crankshaft, connecting bar, crosshead, piston, and pump body. Its main task is devised to carry on the design to water pump and make the necessary intensity checking of it.

本文首先介绍了喷雾泵的结构和特点,然后根据压力与流量的要求选择电动机和曲轴的转速,进而对减速器,曲柄连杆机构,泵体进行设计并且对各个部件进行强度校核.
This paper first introduced the structure and characteristics of the water pump, and then choose the motor and the speed of the crankshaft on the basis of filling the pressure and flux requirement and the choice of motor revolutions of the crankshaft,then design the speed reducer , connecting rod, pump body and then check intensity of every part.
*此段酷似机译产品.很难令人明白.还是逻辑方面出错.choose的主语呢?总不能是This paper.原文的问题.很难去改,还有the choice of motor revolutions of the crankshaft在原文找不到对应处.另外on the basis of ...不如用according to. 另外the motor and the speed of the crankshaft应该是the speed of the motor and the crankshaft.另外then design the speed reducer , connecting rod, pump body and then check intensity of every part.缺少递进关系.
最后把时态调为一致.下面改一下,只求顺嘴些.
In the first place,this paper introduced the structure and characteristics of water pump. Afterward, it chose the speed of the motor and the crankshaft according to the pressure and flux requirement. then designed the speed reducer, connecting rod and pump body,furthermore checked intensity of every part.
设计的内容主要有方案的选定,减速器的设计,泵的结构形式的选择,泵体的设计,曲柄连杆机构的设计,十字头的设计.
The main content of the is selecting programme, the design of the speed reducer, the selection of structure of the pump selection, the design of the pump body,and the design of the connecting rod, the design of the crosshead.
*哎~无话可说了
The main content included the choice of programme, the design of the speed reducer,the pump body, the connecting rod,and the crossheadthe, as well as the selection of the structural style of the pump.
该喷雾泵结构紧凑,占地面积小,符合采煤工作面的要求.
The structure is compact ,and the water pump covers small area.It accord with the need of the coalface.
*哎~最后一句了
because of the compact structure and the small covering area of this water pump,it can fulfil the need of the coalface.
