A double-switched relay cannot close inadvertently with the application of the same current. At least two separate faults would be required to allow this relay to close inadvertently. Double switching , double cutting , or double breaking is the practice of using a multipole switch to close or open both the positive and negative sides of a DC ...
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
Double Switch may refer to: Double switch (baseball), a type of player substitution; Double-switch (basketball), a defensive move to counter a pick and roll by the offense; Double Switch, a 1993 release by Digital Pictures for Sega CD and other platforms; Double switching, using a multipole switch to open or close both sides of an electrical ...
A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. The PCPD pump uses drilling fluid (commonly referred to as drilling mud, or just mud) to create eccentric motion in the power section of the motor which is transferred as ...
Suction line (#3) is an intake line for the mud pump to draw drilling fluid from the mud tanks. Swivel (#18) is the top end of the kelly that allows the rotation of the drill string without twisting the block. Traveling block (#11) is the moving end of the block and tackle. Together, they give a significant mechanical advantage for lifting.
The MK5000C is a 5,000 hp (3.7 MW) North American diesel-electric locomotive developed by MK Rail.At the time of its introduction in 1994, the MK5000C was the most powerful single prime mover diesel-electric locomotive ever made, a title it would hold for only for one year until GE Transportation released its competing 6,000 hp (4.5 MW) AC6000CW model in 1995.
Mud Gas Separator capable of handling 1000-1500gpm Process Flow Diagram For Mud Gas Separator. Mud Gas Separator is commonly called a gas-buster or poor boy degasser. It captures and separates the large volumes of free gas within the drilling fluid. If there is a "kick" situation, this vessel separates the mud and the gas by allowing it to flow ...
Surface mud systems. In the oil drilling industry, effective solids control can be attributed to the overall performance of all the components of the mud systems.Conditioning the drilling fluid with the goal of dramatically lowering maintenance cost, avoiding excessive chemical treatment and maintaining mud systems volume will decrease the chance of equipment failure, unnecessary high mud ...
