Necessary Safety Regulations of Vacuum Degasser for Drilling Safety

Posted by:    Time:2014-04-16     click:

DC series vacuum degasser for drilling safety is a kind of used to handle invasion of new special equipment. This vacuum degasser for drilling safety can quickly remove intrusion into the drilling fluid in various gases. This machine has a very important role to restore the proportion of mud, stable mud property. At the same time vacuum degasser for drilling safety can be used as a powerful blender, which is applicable to all kinds of mud circulation purification system matching. The equipment as part of the negative pressure type deaerator, scientific and reasonable design structure, can realize effective separation of gas and liquid, filter out the impurities, and ensure the exhaust pipe is always open.

Working principle of vacuum degasser for drilling safety: deaerator belongs to vacuum degasser, namely using the vacuum pump suction effect to cause negative pressure zone in vacuum tank  mud under the action of atmospheric pressure. Through the suction tube into the hollow shaft of the rotor, the collision and the role of foam separator will invade the bubbles in the mud. Gas evolution is safe through vacuum pump suction. The mud is due to the weight of empty cavity, then the rotor discharge outside the tank. In addition, because of the vacuum pump simultaneously with the main motor startup and motor connected by high-speed rotating rotor, so, mud can only from the suction pipe into the tank, which will not be inhaled from the suction pipe.

Main features of vacuum degasser for drilling safety:

1. The application of the water separator, the working medium of water ring vacuum pump is in a state of recycling, which can reduce the cost.

2. The main motor offset and the center of gravity is lower.

3. The use of vacuum pump suction effect is mud into the vacuum tank, and uses it to make gas pumped vacuum tank, so there are two kinds of vacuum pump.

4. The suction pipe into the mud tank, in the mud without gas cut, can be used as a powerful blender.

5. Mud through the window into the walls at a high speed rotor and mud in the bubbles completely, degassing effect is better.

Installation requirements of vacuum degasser for drilling safety:

1. Not very strict with ground, as long as the firm can be stable and reliable.

2. When installation, lift, the suction pipe flange has a connection with vacuum tank at the bottom of the flange.

3. Before start, drainage pipe shall be the end of the suction pipe into the mud at the same time, otherwise you will not be able to work.

4. Before start the water hose connected with the water on the centrifugal pump , stop for 3 to 5 min after the water in the vacuum pump filling, then the vacuum degasser for drilling safety starts again. At the same time, open the plug on the water separator. To steam separator in water injection, water spilled from the overflow mouth when to stop, and screw on the plug.

5. At the start, vacuum degasser for drilling safety should learn about the direction of rotation of the motor, vacuum pump and the main motor are marked on the belt cover rotate arrows mark should be in the same direction.

6. On the vacuum control valve adjusting bolt, the vacuum degasser for drilling safety has adjusted in place in the factory test. Please don't budge. It is really necessary to adjust, such as vacuum through low, which will bolt inverse clock direction.
