螺旋式,离心式压缩机的工作原理以及优缺点比较

时间:2018-01-22 08:55:08  来源:原创  作者:永世机械

相信大家对于压缩机的种类以及不同压缩的工作原理和优缺点不是很明白,今天着重给大家讲解一下有关于螺旋式和离心式压缩机的相关知识。

I believe you are not very clear about the type of compressor and the working principles and advantages and disadvantages of different compression. Today, I want to explain to you about the knowledge of screw and centrifugal compressor.


注满螺旋式压缩机通常使用压缩烃和生产气体,流压范围从1-25 bar g(5)。它们具有许多优点,包括改进压缩效率,低流出温度,高可靠性和由于简单的机械构造所致的较少维护。螺旋式气体压缩机必须具备几种功能。它们润滑

The filled spiral compressor usually uses compressed hydrocarbon and production gas, and the flow pressure range is from 1-25 bar g (5). They have many advantages, including improved compression efficiency, low outflow temperature, high reliability, and less maintenance due to simple mechanical structures. The spiral gas compressor must have several functions. They are lubricated

决于为轴承提供足够的润滑油的能力。典型的上部粘度限制是30-100cSt。通常ISO68-220润滑油满足螺旋式压缩机的粘度要求。准确的粘度级别依赖于操作条件和气流成分。

The ability to provide enough lubricating oil to the bearing. The typical upper viscosity limit is 30-100cSt. Usually ISO68-220 lubricants meet the viscosity requirements of the spiral compressor. The exact viscosity grade depends on the operating conditions and the air flow composition.

由于系统的闭环设计,合成产品特别适用于螺旋式压缩机(图表1)。润滑油与压缩气体进入分离器。分离的油经过一个冷却器再回流入压缩机。在这个过程中润滑油的降解可导致如轴承故障,密封不够或腐蚀等压缩机问题。在许

Because of the closed loop design of the system, the synthetic product is especially suitable for the spiral compressor (Figure 1). The lubricating oil and the compressed gas enter the separator. The separated oil is reflued into the compressor through an oil cooler. The degradation of lubricating oil in this process can lead to compressor problems such as failure of bearing, insufficient sealing or corrosion. In Xu

多应用中,合成压缩机润滑油的使用能造成有效的烃压缩和生产气体

In multiple applications, the use of synthetic compressor lubricants can cause effective hydrocarbon compression and production of gas.

离心式压缩机工作原理为,当叶轮高速旋转时,气体随着旋转,在离心力作用下,气体被甩到后面的扩压器中去,而在叶轮处形成真空地带,这时外界的新鲜气体进入叶轮。叶轮不断旋转,气体不断地吸入并甩出,

The working principle of the centrifugal compressor is that when the impeller rotates at high speed, the gas moves to the diffuser behind the centrifugal force, and a vacuum zone is formed at the impeller, when the fresh air flows into the impeller. The impeller rotates continuously, and the gas is constantly inhaled and flung out.

从而保持了气体的连续流动。

Thus the continuous flow of the gas is maintained.
与往复式压缩机比较,离心式压缩机具有下述优点:1、结构紧凑,尺寸小,重量轻;2、排气连续、均匀,不需要级间中间罐等装置;3、振动小,易损件少,不需要庞大而笨重的基础;4、除轴承外,机件内部不需润滑,

Compared with the reciprocating compressor, centrifugal compressor has the following advantages: 1, compact structure, small size, light weight; 2, the exhaust is continuous and uniform and without intermediate tank device level; 3, small vibration, less wearing parts, does not need large and heavy; 4, in addition to bearing parts. Without internal lubrication,

省油,且不污染被压缩的气体;5、转速高;6、维修量小,调节方便。

Oil saving, and does not pollute the compressed gas; 5, high speed; 6, small maintenance, easy to adjust.
