1、空隙增大

1. Enlargement of voids
A、 主机的阴阳转子间的间隔增大。带来的直接结果是紧缩机在紧缩的过程中走漏(即回渗漏)增大,排出机器的紧缩空气体积变小。体现在功率方面就是紧缩机的紧缩功率下降。
A. The interval between the Yin and Yang rotors of the main engine increases. The direct result is that the leakage (i.e. back leakage) of the compressor increases and the volume of compressed air discharged from the compressor decreases. Reflected in the power aspect is the reduction of the compact power of the compressor.
B、阴阳转子与后端盖和轴承处的空隙增大,首要会影响到紧缩机的密封性和紧缩功率,一起对阴阳转子的运用寿数会发生很大的影响,因为许多机械毛病开始成因都是轴承与主轴之间的空隙形成的。
B. The increase of the gap between the Yin-Yang rotor and the back cover and the bearing will primarily affect the tightness and power of the compressor. Together, it will have a great impact on the service life of the Yin-Yang rotor, because many mechanical defects are caused by the gap between the bearing and the spindle.
2、磨损增大
2. Increased wear
众所周知,只要是机械在作业都存在磨损,正常情况下因为有光滑液光滑,磨损会减轻许多,但长时刻高速作业,磨损是在慢慢增大的。以高端轴承为例:在近乎不可能的条件下(如长时刻空转、光滑液满足干净、冷却系统满足好、及运用环境温度、湿度等等),也只能确保数年。就紧缩机主机而言,除轴承外还存在其它部件的磨损。如细微磨损不采纳正确的预防措施,很简单导致磨损增大、形成其它首要部件的损坏和磨损。
As we all know, as long as there is wear in the operation of machinery, under normal circumstances, because of smooth liquid, wear will reduce a lot, but long time high-speed operation, wear is slowly increasing. Take high-end bearings for example: under almost impossible conditions (such as long time idling, smooth liquid to meet clean, cooling system to meet good, and the use of environmental temperature, humidity, etc.), it can only ensure a few years. As far as the compressor main engine is concerned, there are wear and tear of other parts besides bearings. If the correct preventive measures are not adopted for minor wear, it will simply lead to increased wear and other primary components of the damage and wear.
3、部件变形
3. Component Deformation
空气紧缩机主机是紧缩机的中心紧缩部件,其内部部件长时刻处于高温、高压的环境中,再加上高速的作业,时刻一长必定存在部件变形的现象。一起,形成变形的原因还有运用环境因素,而空气紧缩机一般运用的环境的空气中都会有尘土和杂质,这些细小的固体物质在进入机器后,铢积寸累若结成较大的固体块,就有可能形成阴阳转子变形,空隙增大,严峻的会导致主机卡死。

The main engine of air compressor is the central part of the compressor. Its internal parts are in high temperature and pressure for a long time, coupled with high-speed operation, there must be part deformation for a long time. Together, the cause of deformation is also the use of environmental factors, and air compressor generally used in the environment will have dust and impurities, these small solid substances into the machine, baht cumulative accumulation into larger solid blocks, it is possible to form Yin and Yang rotor deformation, increase the gap, severe will lead to the main engine jam.
4、部件损坏
4. Component damage
在空气紧缩机主机部分的易损部件首要有:各种垫片、密封圈、轴油封等,尤其是轴油封,长时刻处于高温、高压、和高速作业的环境中,其运用寿数比大大缩短。其损坏的直接结果是形成紧缩机漏油,如未能及时发现,则会形成阴阳转子和轴承因缺少光滑而烧毁。
In the main part of the air compressor, the most vulnerable parts are: gaskets, sealing rings, shaft oil seals, etc., especially the shaft oil seals, which are in high temperature, high pressure and high speed working environment for a long time, and their service life ratio is greatly shortened. The direct result of the damage is oil leakage of the compressor. If it is not found in time, the Yin-Yang rotors and bearings will be burned because of lack of smooth.
5、本钱添加
5. Cost Added
这儿本钱指保养本钱和电力本钱。因为空气紧缩机主机在长时刻作业未大修,部件磨损增大,一些磨损的杂质留在主机腔内,会形成光滑液寿数缩短,一起,因为杂质的原因,油气分离器芯和油过滤期的运用时刻大大缩短,形成保养本钱添加。在电力本钱方面,因为磨擦增大和紧缩功率下降,必定会形成电力本钱增大。另、因为紧缩机主机的原因形成的气量下降、紧缩空气品质下降也会形成出产本钱的间接增大。
Here the cost refers to maintenance cost and power cost. Because the main engine of air compressor has not been overhauled for a long time, the wear of parts increases, and some abrasive impurities remain in the main engine chamber, which will shorten the life of smooth liquid. Together, because of impurities, the operation time of oil and gas separator core and oil filtration period is greatly shortened, resulting in the addition of maintenance cost. In terms of power cost, because of the increase of friction and the decrease of power contraction, it is bound to form an increase in power cost. In addition, the reduction of air volume and the decrease of compressed air quality caused by the main engine of the compressor will also result in the indirect increase of production cost.
所以,空气紧缩机主机在长时刻作业后未大修可能引起的结果,不只会形成紧缩机本体的严峻损坏,还存在严峻的安全隐患。一起,会给出产带来严峻的直接和间接经济损失。因此,空气紧缩机主机在运转一定时刻后进行预防性大修是必要的,而且是有必要的。
Therefore, the air compressor mainframe may not be overhauled after a long period of operation, which will not only cause serious damage to the compressor itself, but also cause serious security risks. Together, it will bring severe direct and indirect economic losses to production. Therefore, it is necessary and necessary to carry out preventive overhaul of the main engine of the air compressor after a certain time of operation.
6、www.878365.com大修判别与具体内容
6. Discrimination and Specific Content of Air Compressor Overhaul
螺杆www.878365.com的一般寿数为30年左右,但在实践出产中因长时刻保养和修理不到位,许多仅运用了10年乃至更短时刻的螺杆机不光运转状况很差、耗电量巨大、毛病不断、运转费用相当高,不少用户乃至将其归类于“待作废机组”。目前www.878365.com职业进行主机大修断定的方法首要有以下两个:
The general life of screw air compressor is about 30 years. However, in practice, many screw air compressors which have only been used for 10 years or even shorter are not only in poor operation, huge power consumption, constant faults and high operating costs, and many users even classify them as "waste units". At present, there are two main methods to determine the main engine overhaul in the air compressor profession:
依据机组运转时刻断定:www.878365.com组运转时刻累计达到20000小时或者投入运转4年后须安排主机进行大修。
According to the operation time of the unit, it is concluded that the total operation time of the air compressor unit reaches 20000 hours or the main engine must be arranged for overhaul after four years of operation.
依据机组实践运转检测剖析断定:经过对机组运转参数如噪音、运转电流、运转温度、排气量、主机振动等进行相应的数据检测剖析,断定是否需求进行主机大修作业。
According to the analysis of unit operation test, it is concluded that the operation parameters of unit such as noise, running current, operating temperature, exhaust volume and vibration of main engine are detected and analyzed to determine whether the overhaul operation of main engine is needed.
