I don't get the last sentence.
but upon my knowledge, you'd better dumb down your sentence a little bit. it's way too long. and length does not necessarily mean complexity. Take my word. you will get better.

3楼高手啊，
你帮我多翻译几句吧
这几个是剩下的几个句子谢谢啊
------------------------
经过各种洗煤、环保、铝厂、冶炼等场合试用，其性能已达到国内领先水平，其压滤效果、滤干时间、污水污物的防堵性、无泄漏及整机的稳定性均得到用户好评，为各类用户提高效益起到了积极的促进作用。
泵采用双主叶轮正反安装，运行期间配合压滤机内的阻力变化来实现大流量、低压力喂料与小流量、高压力过滤的目的。其特殊的水力性能恰好吻合压滤机由空腔到填满再到滤干的渐进过程。喂料初期不用阀门控制因流量过大引起的电机过载，同时低压力不会对滤板边框产生冲击，减轻了滤板边框上的滤布破损，也不会冲击滤板造成震动，压滤后期的小流量、大压力不易产生憋泵。尤其是泵在后期压榨高压力工作时，独特的叶轮安装方式及副叶轮的作用，保证了轴封基本无泄漏。
根据介质需要，可选择填料密封、单端面机械密封和双端面机械密封（泵自带水箱）。

I don't wanna get overwhelmed. trynna write them out on your own and post them here later. I am ready to correct them for you for sure.

Thanks a lot,but it will surely takes time, i am afraid you maybe not online at that time

well, I have something on my plate right now so I have to take off.
But I'll be around here tomorrow. and if I see your translation, I'll try my best to correct them as soon as I can by tomorrow morning if it is not due by then. but if you cannot wait you can also turn to other guys instead. it's up to you :)

I will translate all of them by myself,and will wait for your correction.
Have a good ~ Waiting for you~

还说第一句吧，1楼中的 最后一句英语对说最后一句汉语的翻译：而设计开发的压滤机专用入料泵产品。It was specialized designed and developed for pressure filter

It is such a type of feeding pump product designed and developed for pressure filters specifically.

by the way, I'm not sure if "feeding pump product" is a correct translation for 入料泵产品. you may double check with others for credibility purpose.

你的英语有点太口语化了吧
资料明显是书面性质强一点的
你翻译的也对
只是感觉跟聊天似的呵呵

is it? not good at this though.
but I think there is no harm to make it casual, because readers may understand it more easily, right?
I think it's likely a introduction of a certain product or something. and the readers may not have the ability and knowledge to understand it if it contains too many professional words and phrases. do you think so?
but if it's a acadamic paper. brush off my words lol.

这样是否好点？
SYA type Pressure Filter Feeding Pump is a specialized pump feeding product for pressure filter. Adopting advanced fluid theory and combining with the feeding condition in different occasions, it was specialized designed and developed for pressure filter.

某些场合是对的呵呵
