Pressure
The pressure size of the pump depends on the depth of the drilling hole, the resistance of flushing fluid (drilling fluid) through the channel, as well as the nature of the conveying drilling fluid. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed.
With the changes of drilling hole diameter and depth, it requires that the displacement of the pump can be adjusted accordingly. In the Mud Pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately grasp the changes in pressure and displacement, a flowmeter and pressure gauge are installed in the Mud Pump.

Famous quotes containing the word pressure:
“By school age, many boys experience pressure to reveal inner feelings as humiliating. They think their mothers are saying to them, “You must be hiding something shameful.” And shucking clams is a snap compared to prying secrets out of a boy who’s decided to “clam up.””
—Ron Taffel (20th century)
“I am convinced that our American society will become more and more vulgarized and that it will be fragmentized into contending economic, racial and religious pressure groups lacking in unity and common will, unless we can arrest the disintegration of the family and of community solidarity.”
—Agnes E. Meyer (1887–1970)
“The universal social pressure upon women to be all alike, and do all the same things, and to be content with identical restrictions, has resulted not only in terrible suffering in the lives of exceptional women, but also in the loss of unmeasured feminine values in special gifts. The Drama of the Woman of Genius has too often been a tragedy of misshapen and perverted power.”
—Anna Garlin Spencer (1851–1931)
