压缩机是中国国有工业企业发展的一支重要队伍,作为通用产品,广泛应用于化工、石油、矿山、机械、冶金、气体管道输送等各行业,与其他行业的发展紧密相关.今天中国分类信息网的小编就来说说压缩机专用光电液位开关。

Compressor is an important team in the development of China's state-owned industrial enterprises. As a general product, compressor is widely used in chemical industry, petroleum, mining, machinery, metallurgy, gas pipeline transportation and other industries. It is closely related to the development of other industries. Guan.

光电液位开关是利用光在两种不同介质界面发生反射折射原理产品内部包含一个近红外发光二极管和一个光敏接收器。发光二极管所发出的光被导入传感器顶部的透镜。当液体浸没光电液位开关的透镜时,则光折射到液体中,从而使接收器收不到或只能接收到少量光线。光电液位开关通过感应这一工况变化,接收器可以驱动内部的电气开关,从而启动外部报警或控制电路。如果没有液体,则发光二极管发出的光直接从透镜反射回接收器。

The photoelectric liquid level switch consists of a near infrared light emitting diode and a photosensitive receiver, which is based on the principle that light reflects and refracts at the interface of two different dielectrics. The light emitted by the light emitting diode is directed to the lens at the top of the sensor. When the liquid is immersed in the lens of the photoelectric liquid level switch, the light is refracted into the liquid, so that the receiver can not receive or can only receive a small amount of light. The photoelectric liquid level switch can drive the internal electrical switch by inducing the change of the working condition, thus starting the external alarm or control circuit. If there is no liquid, the light emitted by the light emitting diode is directly reflected back from the lens to the receiver.

光电液位开关在压缩机中的作用如下:液位开关部件作为离心压缩机油箱润滑油液位监控核心部件,其涉及的液位开关接头、筒体和液位计整体装配密封性能决定了其能否正常使用。其中润滑油的油压差,油温与油位高度,是保证机组在正常工作条件下,运动零件润滑和冷却的三个要素。

The function of photoelectric liquid level switch in compressor is as follows: as the core component of centrifugal compressor oil tank lubricating oil level monitoring, the liquid level switch connector, cylinder and level gauge assembly and sealing performance determine whether they can be used normally. The oil pressure difference of lubricating oil, oil temperature and oil level are the three key factors to ensure lubrication and cooling of moving parts under normal working conditions.

高位油箱是一种保护性设施,机组正常运行时,高位油箱的润滑油有底部进入,经过过滤器过滤后,从高位油箱返回润滑油箱。当油泵发生故障时,高位油箱的润滑油将沿着油路靠重力作用流入润滑处,以维持机组运行过程中的润滑需要。高位油箱要有一定的储油量,一般应该维持不小于5min的供油时间。在润滑油泵出口到润滑油初之前的总管线上,需要设置止回阀,如果油泵故障而不能供油时,则止回阀立即关死,使得高位油箱的润滑油必须经轴承等润滑处进入回油箱管线,再返回润滑油箱,防止高位油箱的润滑油短路,从而避免机组运转过程中轴瓦烧坏。

High-level tank is a protective facility. When the unit is in normal operation, the lubricating oil of high-level tank enters at the bottom. After filtering by filters, it returns to the lubricating tank from high-level tank. When the oil pump fails, the lubricating oil of the high oil tank will flow into the lubrication area along the oil road by gravity to maintain the lubrication requirement during the operation of the unit. The high-level tank should have a certain amount of oil reserves, which should be maintained for not less than 5 minutes. In the main pipeline before the outlet of the lubricating oil pump to the beginning of the lubricating oil, check valves need to be installed. If the oil pump fails and cannot supply oil, the check valves will be shut down immediately, so that the lubricating oil of the high-level oil tank must enter the return oil tank pipeline through the lubrication of bearings and other places, and then return to the lubricating oil tank to prevent the short circuit of the lubricating oil of the high-level oil tank. Avoid bearing bush burnout during unit operation.

油位高度,是润滑油在贮存容器中的高度。各机组的贮油容器均设置有油位显示装置。一般规定贮油容器内的油位高度应位于视镜中央水平线上下5毫米。规定油位高度的目的是为了保证油泵工作时,油循环所必须的供应量维持连续不断循环的工作效果。油位过低易造成油泵失油,甚至酿成机组运行故障或损坏事故。因此,必须在油位过低时,及时向润滑系统内补充相同牌号的润滑油,直到油箱内的油位高度达到视镜的规定的高度为止。

Oil level height is the height of lubricating oil in storage containers. The oil storage containers of each unit are equipped with oil level display devices. It is generally stipulated that the oil level in the oil storage container should be 5 mm above and below the central horizontal line of the mirror. The purpose of regulating oil level height is to ensure that the supply quantity necessary for oil circulation can maintain the effect of continuous and continuous circulation when the oil pump works. Excessive low oil level can easily cause oil loss of oil pumps, even lead to unit operation failure or damage accidents. Therefore, when the oil level is too low, the same brand of lubricant must be added to the lubrication system in time until the oil level in the tank reaches the required height of the mirror.

另一方面压缩机的工作介质很多都具有腐蚀性,其腐蚀性介质致使阀片的材料疲劳极限很快的降低。同时气流以较高的速度工作并冲刷阀片很容易使阀片的表面组织破坏,产生腐蚀出现麻点和凹坑。压缩机工作中压缩的介质有一定的湿度,油水分离过程中分离不净的润滑油与压缩气体经过冷却器析出的水分和在气体当中,气体流过气阀的时候,会残留一些物质黏贴在阀座密封口、阀片和与升程限制器等工作零件表面,随之形成液膜。液膜所产生的黏着力阻碍着阀片的正常运动,导致阀片滞后开启、关闭、加大气流的顶推力。当液膜油水含量越多,黏着力就越大,严重的影响压缩机气阀阀片的寿命,气体净化效果不好时,很容易造成气阀阀片的损坏。

On the other hand, many working media of compressor are corrosive, which causes the material fatigue limit of valve plate to decrease quickly. At the same time, the airflow working at a higher speed and scouring the valve sheet can easily destroy the surface structure of the valve sheet, resulting in corrosion pits and pits. Compressed medium in compressor work has a certain humidity. In the process of oil-water separation, the water separated from lubricating oil and compressed gas through the cooler and in the gas, when the gas flow through the air valve, some substances will remain and stick to the seats, valves and working parts such as lift limiters. It forms a liquid film. The viscous force produced by the liquid film hinders the normal movement of the valve sheet, leading to delayed opening and closing of the valve sheet and increasing the top thrust of the air flow. When the oil and water content of liquid film is more, the adhesion force is greater, which seriously affects the life of compressor valve discs. When the effect of gas purification is not good, it is easy to cause the damage of valve discs.

因此压缩机组中需要测量的液位有主油箱润滑油液位、注油器油箱液位、中间分液罐凝液液位及填料漏气收集罐液位。在压缩机液位测量中一般采用玻璃液位计、浮力式液位计、差压式液位计、液位变送器、液位开关等都可以作为测量腰围的高度。

Therefore, the liquid level needed to be measured in the compressor unit includes the main oil tank lubricating oil level, the oil tank level of the injector, the condensate level of the intermediate liquid separator and the liquid level of the filler leak collecting tank. In the measurement of compressor level, glass level gauge, buoyancy level gauge, differential pressure level gauge, level transmitter and level switch can be used as waist circumference height measurement.
