How to correctly use the drilling fluid vacuumde degasser

ZCQ series Vacuum Degasser is a special-purpose device and a new type one for the treatment of gas in the drilling fluids. It can get rid of various gas of invasive drilling quickly. Vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time vacuum degasser can be used as a heavy-power agitator and supported applicable to all types of mud circulation purification system.

Working theory

The degassers are used to clean the gas in the drilling fluid, to ensure the drilling fluid property relatively stable, to guarantee the steady operation of swirlers. 

The vacuum degassers can be grouped into two kinds: ordinary pressure type and vacuum type. The ordinary pressure degasser is to use the centrifugal to take out gas to invade the mud, with the help of centrifugal force to make the mud spraying in the jet tanks and striking on the wall to make gas releasing. The vacuum degasser is to use the suction of the centrifugal, forming negative pressure in the vacuum tanks, under the action of drilling fluid at atmospheric pressure, through the suction pipe into the hollow shaft, then by umbrella piece of around the hollow shaft assembly, they jet to the skin of tank.

Installation and use

It is must be installed before drilling 

The installation should be steady, connection, tension and reasonable. 

The filter screen should be installed in the air inlet place of exhaust pipe, preventing particles enter into vacuum degasser.

Checking before start

The rotation of motor, vacuum pump and the main motor should be unanimous with mark direction.

The end of discharge pipe and inlet pipe should be immersed in mud pool at the same time.

Turn the coupling number ring to ensure it is didn’t locked or damage phenomenon. 

After use

After use we must discharge the water in the pump or gas water separator.

It is must be tested run every week.

Before enter into gas layer, it is must be normally operated.
