External type metering tank: total 4 m3 Sulfuric Acid Storage Plastic Tank (3 inches) long rod pump installed in the grouting pump, connected to the wellhead overflow prevention pipe (oil pipe) through the grouting pipe.
There are two inlets on the mud tank, which are respectively connected to the buffer pool of the vibrating screen (near the groove on the vibrating screen of the channel in the welding direction of the liquid replenishment port, and install the control door, the menstruation is 100 mm), the inlet pipe joint of the desander (except the The liquid replenishment port on the liquid inlet pipe of the sander is welded to the measuring tank, and the control door is installed), the mud outlet (the liquid outlet is welded to the circulating Sulfuric Acid Storage Plastic Tank, and the control valve is installed, and the menstruation is 100 mm), and the measuring gauge. When drilling needs to be filled with mud, the grouting pump metering tank mud will pass through the pipeline in the wellbore, and then the pump volume data can be read by measuring the scale scale. When drilling, the wellbore is used as the return mud, and the mud outlet is installed in the shaker buffer pool, and the wellbore mud is injected into the metering tank, and then the data of the returned mud volume can be read by measuring the scale of the scale. When the mud is injected into the wellbore, if there is no mud in the metering tank, the mud tank is circulated from the desander sand pump to replenish the mud in the metering tank.
When the wellhead returns to the drilling mud tank, such as the Sulfuric Acid Storage Plastic Tank, the discharge valve is fully opened, and the excess mud tank is opened. 2-cycle original metering tank: Conical tank, required for each team based on matching can calculate the total amount. Polypropylene PP metering tanks have been installed in dosing pumps, grouting pumps and external types.
