The displacement of the mud pump in the process of operation is calculated by discharging several liters per minute. The diameter of the drilling hole and the required return velocity of the flushing liquid from the bottom of the hole are related in the process of using the equipment. The larger the hole size of the mud pump, the larger the displacement required.
The size of the mud pump pressure mainly depends on the depth of the borehole, flushing fluid in the use of the process will pass through the channel resistance and the nature of the transmission of flushing fluid, in general, the deeper the drilling pipe resistance will be greater, the pressure will be higher in use.
The mud pump can work effectively with the change of the diameter and depth of the drill hole, the displacement of the pump can be adjusted at any time. The equipment will be equipped with a gearbox and a hydraulic motor to adjust the speed in the pump mechanism. In this way, the purpose of changing the displacement can be achieved.
In order to accurately grasp the pressure of the pump and the change of displacement during the operation of the mud pump, the mud pump should be equipped with its flow meter and pressure gauge, and the drilling personnel can understand the operation of the pump at any time during the use.
The mud pump transport liquid flow is relatively stable and there is no over-current, agitation, pulsation and shear slurry phenomenon. The pressure discharged during the use of the equipment is directly independent of the rotational speed, and the low flow rate can also maintain a high discharge pressure.
Mud pump speed and flow is proportional, in the use of the process can be effectively through its variable speed mechanism or speed motor, so that it can be in a certain extent to achieve the regulation of its flow, and the self-suction capacity of the equipment is strong, no need to install the bottom valve can be directly pumped liquid.
