螺桿泵的發(fā)展概述
Overview of the development of screw pump
泵是一種能量轉(zhuǎn)換的機器，它把原動機的機械能或某種流體的能量傳遞給輸送的液體，使其能量增加。就泵的歷史而言，它是一種非常古老的機械。在古代它只是一種改變液體位能的提水工具，人們習(xí)慣于把泵稱之為水泵，并把它歸入水力機械。隨著科學(xué)技術(shù)的發(fā)展，泵的種類也在不斷增多，各種類型的泵在國民經(jīng)濟的各個領(lǐng)域得到了廣泛的應(yīng)用，輸送的介質(zhì)也早已超出了水的范疇。螺桿泵就是這樣一類新興的泵。螺桿泵按其作用原理屬于容積式泵的類型，若它按對液體能量傳遞的方式，則屬于轉(zhuǎn)子泵，故可稱之為容積式轉(zhuǎn)子泵。如今，螺桿泵雖然仍有用來提水的，但更多的是用于工業(yè)領(lǐng)域，人們通常把它歸為工業(yè)泵的范疇。螺桿泵自20世紀(jì)30年代初問世以來，還只有80來年的歷史，由于具有其他類型泵不能取代的特點，得到了迅猛的發(fā)展，成為一種新興的工業(yè)用泵。若泛指螺桿泵這一類泵的使用范圍，則可以說它能夠輸送超出其他任何類型泵所能輸送的介質(zhì)的范圍！因此，螺桿泵越來越受到人們的重視，得到越來越廣泛的應(yīng)用，有著極為廣闊的發(fā)展前景。
The pump is a machine of energy conversion, it transfers motive of the mechanical energy or a fluid energy totransport liquid, to increase energy. Pump in history, it is a very old. In ancient times, it is only a change of liquid
potential energy water tool, people used to pump called the water pump, and put it into the hydraulic machinery.With the development of science and technology, pump types are also increasing, various types of pumps are
used in many fields of national economy, the transmission medium has already exceeded the watercategory. Screw pump is a new class of pump. Types of screw pump according to the principle of volume typepump, if it is
according to the transfer of liquid energy, belong to the rotor pump, so it can be called a volume typerotor pump. Now, although there are still used to pump water, but more is used in industrial field, people usually put it into
the category of industrial pump. Since the advent of screw pump since the early nineteen thirties, was only80 years of history, has the characteristics of other types of pumps can not be substituted, got rapid development,
become a new industrial pump. If the scope of use refers to the screw pump this kind of pump, we could say it cantransport beyond any other type of pump can transport the media! Therefore, the screw pump more and more
attention by people, has been used more and more widely, has a very broad prospects for development.
創(chuàng)新是科學(xué)技術(shù)發(fā)展的靈魂，對于螺桿泵來說也是如此。正是由于不斷的創(chuàng)新，螺桿泵在近54年來得到了飛速的發(fā)展，新品種不斷涌現(xiàn)，使用范圍也不斷擴大，成了各國國民經(jīng)濟領(lǐng)域*的一種機械設(shè)備。讀者應(yīng)在理解掌握螺桿泵的原理和構(gòu)成要素的基礎(chǔ)上，深入了解國內(nèi)外現(xiàn)有各種類型螺桿泵的特點和不足，著力于開展對現(xiàn)有的產(chǎn)品的改進(jìn)提高和研究創(chuàng)新，使螺桿泵這一專業(yè)得到更快的發(fā)展和提高。
is the soul of the development of science and technology, but also for the screw pump. It is because ofconstant innovation, screw pump has been rapid development in the past 54 years, new varieties are emerging,
the use scope is expanding, has become a kind of indispensable mechanical equipment of national economy. The reader should be based on the understanding of principle of screw pump and the elements, a deep
understanding of the characteristics of existing various types of screw pump at home and abroad, to carry out improvement andinnovation to the existing product, the screw pump the professional faster development
