3、平整、坚实的地面上，用绷绳拉紧。6.2为了减少排气摩擦阻力，建议排气管汇采用最小内径不小于200mm。6.3安装管汇时要注意固定，防止管线移动，管汇连接参照示意图。七、操作7.1应严格按照压力容器安全操作规程进行使用和管理。7.2液气分离器在使用中，经常性观察压力表的压力变化；当分离罐内压力超过1.55MPa时，安全阀自动打开，排气泄压。7.3分离器使用完毕后，应关闭进液管与节流管汇相连接的阀门，并打开排污阀门，清除分离罐内残留的钻井液。八、维护保养及使用注意事项8.1使用时如发现泥浆排出管汇液体受阻，可将管汇侧面的螺塞清砂口打开清砂；8.2分离器总成属受压容器，必须在规定的工作压力和工作环境
4、使用，严禁超压使用。安全阀应定期校验，每年至少一次。8.3液气分离器挡板应每口井检查一次，损坏时应及时更换。8.4严禁对分离器总成施焊。8.5当并联使用时，排液管和排气管要单设，切忌共用。九、安装简图Contents1. General Description62. Principle63. Features64. Structure65. Specifications76.

5、1. General Description YQF-8000/1.5 liquid-gas separator is a special kind of equipment for primary degasification from gas-bearing drilling fluid in the process of drilling. 2. PrincipleThe gas-bearing drilling fluid from throttling manifold flows into decompression tank through incoming-stream man
6、ifold of separator, then enters the separating tank through output pipe; The gas-bearing drilling fluid dashes on a series of baffles, it makes the bubbles in drilling fluid break up. And when the drilling fluid flows through the surface of baffles, it becomes turbulence to enable the gas separate f
7、rom it. The bubbles are kept on the surface of baffles and inflate and break up.3. FeaturesYQF-8000/1.5 liquid-gas separator has following advantages: adjustable support height, easy installation and maintenance, little spare parts, reliable performance, high quality and cheap.4. StructureYQF-8000/1
8、.5 liquid-gas separator mainly consists of base, stand type adjustable supporting, separator assembly, accessory pipe manifold, 1/2（025Mpa） pressure meter and A42Y-40 safety valve.Skeleton layout for Liquid-gas Separator 1.inlet pipe 2.separating tank 3.outrigger assembly 4.fixed tube 5. decompressi

To keep it stable, tighten it by ropes whose ends are inserted into ground.6.2 In order to reduce the friction
11、al resistance the min. internal diameter of exhaust manifold should be no less than 200mm.6.3 Fixation is necessary while install pipe manifold. Connection of pipes should strictly accord with the installation drawings. 7. Operation 7.1 Operate and manage the separator according to Safely operating
12、instruction of pressure container.7.2 Observe the pressure indication of the pressure meter when the separator works. When the pressure in the separating tank is higher than 1.55Mpa, the safety valve will open automatically to discharge air and decompress.7.3 Every time after the separator is used,
13、close the valve between incoming-stream pipe and throttling manifold, and open the drain valve to let the rest mud out.8.Maintenance and Cautions8.1 Open the screw plug for sand discharge in the manifold side to remove sand when the mud discharge manifold is blocked.8.2 The separator assembly is pre
14、ssure container, so it must be used in designed working pressure and surroundings. Overpressure work is forbidden. The safety valve should be checked at least once a year.8.3 The baffle should be checked after a well has been completed. Replace it if there is something wrong.8.4 Welding on the separator assembly is forbidden.8.5 The exhaust pipe and liquid discharge pipe should be arranged separately when the separator is paralleled.
