Abstract
En una medicion durante la perforacion o un sistema similar, una válvula de escape del cilindro de accionamiento de presion balanceada es conducida mediante un piston de sentido alterno. El reinicio del piston de sentido crea un balance de presion a través de la válvula de escape, de manera que la presion dentro del cilindro de accionamiento se aplica a ambos lados de la válvula de escape. Una vez que el piston de sentido es conducido más allá de la palanca que permite que la presion del cilindro de accionamiento tiene una presion de compensacion igual a la presion de la válvula principal aguas abajo, el cilindro de accionamiento fuerza a la válvula de escape para que se abra, disminuyendo a presion del cilindro de accionamiento. La reduccion de la presion permite que el piston de sentido se ponga a cero, reiniciando el proceso. El inicio y reinicio cíclico y del piston de sentido resulta en oscilaciones de presion dentro del conducto. La frecuencia de oscilacion es controlada ya sea por la velocidad en que al fluido se le permite entrar en el cilindro de accionamiento o mediante un muelle utilizado para interrumpir el funcionamiento del piston de sentido.In a measurement during drilling or a similar system, an exhaust valve of the balanced pressure actuating cylinder is driven by an alternating direction piston. Resetting the sense piston creates a pressure balance through the exhaust valve, so that the pressure inside the actuating cylinder is applied to both sides of the exhaust valve. Once the sense piston is driven beyond the lever that allows the pressure of the drive cylinder to have a compensation pressure equal to the pressure of the main valve downstream, the drive cylinder forces the exhaust valve to that opens, decreasing under pressure from the drive cylinder. Pressure reduction allows the direction piston to zero, restarting the process. Cyclic start and restart of the sense piston results in pressure fluctuations within the duct. The frequency of oscillation is controlled either by the speed at which the fluid is allowed to enter the drive cylinder or by a spring used to interrupt the operation of the direction piston.
