空气压缩机是一种用以压缩气体的设备。空气压缩机与水泵构造类似。大多数空气压缩机是往复活塞式,旋转叶片或旋转螺杆。离心式压缩机是非常大的应用程序。下面大家一起来看看空压机的组成结构吧。

Air compressor is a kind of equipment to compress gas. The structure of air compressor is similar to that of water pump. Most air compressors are reciprocating plug type, rotating blades or rotating screws. Centrifugal compressors are very large applications. Let's take a look at the composition of the air compressor.

一、油循环系统:在启动前,首先启动油泵控制系统,油泵控制系统启动后保证空压机各润滑部件润滑良好,同时油泵控制系统可通过内置的温控阀来调节内部油压和油温,以满足系统需要。

1、 Oil circulation system: before starting, the oil pump control system should be started first. After the oil pump control system is started, all lubricating parts of the air compressor can be well lubricated. At the same time, the oil pump control system can adjust the internal oil pressure and oil temperature through the built-in temperature control valve to meet the needs of the system.

二、气路循环系统:压缩机工作时,空气经过自洁式空气过滤器被吸入,通过PLC自动清洗过滤器,空气在经过进口导叶自动调节后进入压缩,经压缩后的气体温度较高,然后进入中间冷却器进行冷却(水走管内,气走管外,中冷器的水流量要求为110m/h)之后。进入二级压缩系统,为避免系统中的气体倒入压缩腔内(避免带压起动)在压缩机的排气管道安装有一只悬挂全启式止回阀,压缩机排出的气体推开止回阀进入排气消声器,然后进入冷器,二级后冷器,再进入排气主管道。

2、 Air circulation system: when the compressor is working, air is sucked through self-cleaning air filter and cleaned automatically by PLC. The air enters into compression after automatic adjustment of inlet guide vane. The compressed gas temperature is higher, and then it enters the intercooler for cooling (water goes in the pipe, gas goes outside the pipe, and the water flow of intercooler is required to be 110m / h). When entering the secondary compression system, in order to avoid the gas in the system from pouring into the compression cavity (to avoid starting with pressure), a suspended full open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve open to enter the exhaust muffler, then enters the cooler, the secondary aftercooler and then enters the main exhaust pipe.

三、水路循环系统:冷却水通过管道进入空压机中间冷却器对压缩排出的气体进行冷却降温,再进入后冷器对排气进行冷却,另一路冷却水进水管道经过主电机上部的两组换热器冷却电机绕组,还有一路对油冷却器进行冷却。

3、 Water circulation system: the cooling water enters the intermediate cooler of the air compressor through the pipeline to cool the compressed exhaust gas, and then enters the aftercooler to cool the exhaust gas. The other cooling water inlet pipe cools the motor winding through the two groups of heat exchangers on the upper part of the main motor, and one way cools the oil cooler.

四、配电系统:空压机为2000kW高压电机(10kV)采用全压启动,控制柜为户内交流、金属铠装抽出式开关设备,开关设备由固定的柜体和可抽出部件即手车两大部分组成,实现控制、保护、监测的目的,具有“五防”功能。

4、 Power distribution system: the air compressor is 2000kW high-voltage motor (10kV), which adopts full voltage starting. The control cabinet is indoor AC and metal armored draw out switch equipment. The switch equipment is composed of fixed cabinet and extractable parts, namely handcart, to realize the purpose of control, protection and monitoring, and has the function of "five prevention".

五、屏保护系统:信号装置分为事故信号和预告信号两种。事故信号的主要任务是在断路器事故跳闸时,能及时地发出音响信号,并使相应的断路器灯光位置信号闪光。预告信号的主要任务是在运行设备发生异常现象时,瞬时或延时发出音响信号,并使光字牌显示出异常现象的内容。

5、 Screen protection system: signal device is divided into accident signal and warning signal. The main task of the accident signal is to send out sound signal in time and flash the corresponding light position signal of the circuit breaker when the circuit breaker trips. The main task of the warning signal is to send out the sound signal instantaneously or delay in case of the abnormal phenomenon of the running equipment, and make the light plate display the content of the abnormal phenomenon.

六、直流电源系统:全自动免维护铅酸蓄电池直流电源成套设备,由充电装置屏,直流馈电屏和蓄电池组成,具有自动稳流,自动稳压,自动调压等功能,为信号屏和高压控制系统提供电源。

6、 DC power supply system: a complete set of automatic maintenance free lead-acid battery DC power supply equipment, which is composed of charging device panel, DC feed panel and battery, has the functions of automatic current stabilization, automatic voltage stabilization and automatic voltage regulation, providing power for signal panel and high-voltage control system.

七、DTC控制系统:DTC控制屏是空压机的“大脑”,各类现场传感器的数值,汇总至DTC控制屏,在DTC控制屏上显示各类运行参数,并监视空压机各部分的运行状态,当某些参数超出允许范围时,DTC会发出相应的报警或自动使空压机停机。

7、 DTC control system: the DTC control panel is the "brain" of the air compressor. The values of various field sensors are summarized to the DTC control panel. Various operating parameters are displayed on the DTC control panel, and the operation status of each part of the air compressor is monitored. When some parameters exceed the allowable range, DTC will send out corresponding alarm or automatically shut down the air compressor.
