The application of rotary vane vacuum pump in degasser: There are two main reasons for the application of rotary vane vacuum pump in degasser. One is to suck the air-invading mud from mud tank to the top of degasser, so that it can form a thin layer flow on baffle, cone or funnel.The other is to discharge the gas released by the degasser “tank“ and the incoming air.Rotating vane vacuum pumps can also generate pressure and emit gas through slender exhaust pipes.
It is very important to ensure that the floating ball always works properly to prevent the mud level in the tank from rising and entering the rotary vane vacuum pump through the pipeline.A dehydrator was installed on the vacuum pipe.It is usually used to collect swallow vapors in hot mud and condense them into liquids at the bottom.When deaerator is closed, water can be discharged.The upper part of the dehydrator is equipped with a floating ball with a safety valve. If the water vapor condensation or the liquid level of the vacuum tank is too high to allow the mud to enter the dewaterer, the float ball will close the passage to the vacuum pump. When the safety valve on the upper part of the dehydrator leaks and the mud enters the vacuum pump, the cylinder block, piston ring and bearing will be grinded.If this happens, the rotary vane vacuum pump must be removed and thoroughly cleaned.If the relief valve is stuck and open, a large amount of mud will pass through the relief valve, damaging the valve, piston and pull rod.When the mud thruster enters the crankcase, the oil level will rise.This is also a sign of valve failure.
1. Pump the slurry into vacuum “tank“ by rotating the vane vacuum pump and pump the gas out of vacuum “tank“.Vacuum pumps play two different roles here.
2. Rotary vane vacuum pump in the working process, always in isothermal state, suitable for flammable and explosive gas suction, reliable safety performance.
3.Three. The mud is injected into four walls at high speed through the window of the rotor.The bubbles in the mud are completely broken and have a good degassing effect.
4.four. The main motor is biased and the center of gravity of the whole machine is reduced.
5.five. The belt drive avoids the complexity of the deceleration mechanism.
6. The application of steam-water separator will not result in the simultaneous discharge of water and gas, so that the exhaust pipe is always unblocked.In addition, it can circulate water to a vacuum pump to save water.
7.seven. The straw is inserted into the mud “tank“ and can be used as a high-power agitator without air immersion.
