Using just a few parts per million of the drag reducer helps to reduce the turbulence inside the pipe. Because the oil pushes up against the inside wall of the pipe, the pipe pushes the oil back down causing a swirling of turbulence to occur which creates a drag force. When the polymer is added, it interacts with the oil and the wall to help ...
Inside of a 231 New Process Gear transfer case. Part-time/Manual, shift on the fly Part-time/Manual, shift on the fly A transfer case is an intermediate gearbox that transfers power from the transmission of a motor vehicle to the driven axles of four-wheel-drive , all-wheel-drive , and other multi-axled on- and off-road machines.
In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...
A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap ( faucet ) where the gland is usually packed with string which has been soaked in tallow or similar grease.
The M25 tank transporter (G160) was a combination 6x6 M26 armored heavy tank transporter/tank recovery tractor and companion 40-ton M15 trailer introduced into US Army service in Europe in 1944–45. Manufactured by Pacific Car & Foundry Co. , it was a substantial upgrade over the Diamond T M19 transporter/trailer duo introduced in 1940.
The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to stall or cause cavitation when drawn into the pump. Eccentric reducers exhibit a unique design with one side having a larger diameter and the other side being smaller and offset from the centerline.
The prototype of M20 MRAP was unveiled by Serbian Defence Ministry in June 2020. It was developed jointly by Military Technical Institute, FAP and Zastava TERVO.M20 is based on FAP 2228 6x6 chassis and uses "CUMMINS ISLe 8.9" engine (power 340 HP), an "ALLISON 3000S" gearbox and a "ZF STEYR 1600/396" drive distributor.
