DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
Positive displacement motors were introduced in the 1960s. The first positive displacement motor (PDM) was the DynaDrill, a high-speed, low-torque motor. After we have. .
The PDM is made up of several sections: 1. The bypass valve or dump sub. 2. The motor section. 3. The universal joint or connecting rod section. 4. The bearing section with drive sub. .
Torque is directly proportional to the motor differential pressure. This makes the tool very simple to operate. RPM is directly proportional to flow. .
Before going in deep for the main drilling mud motor components, we have gathered some drilling mud motor diagrams to help you. .
PDMs come in various configurations. As we mentioned, the stator will have one more lobe than the rotor. 1. The first types of PDMs, and the. [pdf]
