1、对于恢复泥浆的比重、稳定泥浆的粘度性能，降低钻井成本，有很重要的作用，同时，在泥浆不含气体的情况下，还可用作大功率的搅拌器使用。2、主要技术参数处理能力m3/min真空度mmHg真空泵功率kW主电机功率转速r/min44005303158763、工作原理该除气器属于真空式除气器，即利用真空泵的抽吸作用，在真空罐内造成负压区，泥浆在大气压的作用下通过吸入管进入转子的空心轴，再由空心轴四周的窗口，呈喷射状甩向罐壁，由于碰撞及泡沫分离器的作用，浸入泥浆中的气泡破碎，气体逸出，通过真空泵的抽吸被排往安全地带。泥浆则由于自重进入排空腔，经转子排出罐外。值得说明的是，由于真空泵与主电机同时启动，与主电机相

2、连的转子亦呈高速旋转状，所以，泥浆只能从吸入管进入罐内，不会从排出管被吸入。4、结构特点4.1利用真空泵的抽吸使泥浆进入真空罐内，并利用其使气体被抽出真空罐外，真空泵在此起了两种不同的作用。24.2水环式真空泵在工作过程中，始终处于等温状态下，适用于易燃易爆的气体抽吸，安全性能可靠。4.3泥浆通过转子的窗口高速射向四壁，泥浆中的气泡破碎彻底，相应地来讲，除气效果比较好。4.4主电机偏置，整机重心降低。4.5 采用皮带传动，避免了减速机构的复杂化。4.6汽水分离器的应用，使水环真空泵的工作介质处于循环使用状态，可以降低使用成本。4.7吸入管伸入泥浆泵内，在泥浆无气浸的情况下，可作为大功率搅拌器使

3、用。5、安装与使用5.1安装时，对场地要求不甚严格，只要无明显倾斜即可；5.2启动前，应将排液管及吸入管的末端同时浸入泥浆中，否则，将无法工作；排出管必须插入泥浆槽液下以下；5.3启动前，应检查汽水分离器的水位高度，以与真空泵的中心高度平齐为好。5.4启动后，查看电机的旋转方向，应与罐体及泵上箭头所指方面一致。5.5真空泵上的16胶管与水源相接。5.6用户自备排液软管及排气软管。根据泥浆比重调整负压压力，调整范围在0.016Mpa0.03Mpa之间。6、维护保养6.1除气器真空罐的顶盖应每周清洗一次，以免杂物堵塞气体通道。可用清水冲洗，对象为顶盖上的气体收集室和泡沫分离器。冲洗时断开真空管线，

4、卸下丝堵及表座，将高压水管插入每次35分钟。6.2使用完毕后，应冲洗真空罐内的转子及吸入管。切断电源，卸下视堵板（及椭圆法兰堵板），检查零部件有无损坏，并清除罐内异物，用高压水管冲洗罐壁及转子。6.3每次完钻后均应进行上述清洗工作，保证再次正常使用。6.4工作环境温度高于30时，要随时检看真空表，及时更换汽水分离器中的水，保持水温不超过35。6.5冬天使用后，要及时放掉汽水分离器及泵内的积水，防止冻裂。7、故障排除序号故障故障原因排除方法电机转速下降皮带松动调整电机张紧螺钉真空度下降真空罐密封不严紧固真空罐螺丝真空度过高，排气管出泥浆调节阀关闭调节调节阀螺钉8、易损件名称规格及型号数量三角皮带

6、pecial equipment used in gas cutting fluid in drilling engineering. It can match various mud cleaner systems. It is very important in restoring mud gravity, stabilizing mud viscosity and reducing the drilling costs. Furthermore, It can also be used as agitator with great power stirrer if there is no

7、 gas on the mud.2.Specifications:2.1 Treatment capacity: 4m/mm2.2 Degree of vacuum: 400530mmHg2.3 Power of vacuum pump:3KW2.4 Power of main motor:15KW2.5 Rotary speed: 876 r/min3. Working Principle:The vacumm pump is used to pump the was sucked into the air in the tank out to make vacumm area in the

8、 tank, thus mud in the area will enter the rotor hollow shaft through the sucking pipe, and then be thrown out of the windows around the hollow shaft. Because of the bump and the bubbles separator, the bubbles in the mud will be separated and blow out. The vacuum pump will pump them to safe area, th

9、e mud will enter the discharge room and be discharge room and be discharged through the rotor. 7Notice: Because the vacuum pump and main motor start at the same time, the rotor is in high speed as well. So the mud will be drawn through the sucking pipe only.4.Features:4.1 The vacuum has two differen

10、t function. One is pumping mud into vacuum pump, the other is pumping gas out of vacuum pump.4.2 Safety: the vacuum pump is in constant temperature when it works. So it can suck flammable and explosive gas.4.3 Good effect: the mud is thrown through the rotor windows, thus the bubbles will bump compl

11、etely.4.4 Low center of gravity: the main motor is offset.4.5 The belt drive simplifies the speed reducer.4.6 Low costs: the steam-water separator makes the working medium in recycle state.4.7 If there is no gas in the mud, it can also be used as an agitator with great power.5. Installation and oper

12、ation:5.1 The installation base should not be installed with obvious incline.5.2 Before starting, put the end of the fluid discharge and suction pipe into the mud. Otherwise, it will not operate normally.85.3 Before starting, examine the water lever in the steam-water separator, it should be at the
