HP = Horse Power #2 Horsepower required to Drive a Hydraulic Pump P HP = q p / 1714 where HP = horsepower (HP) q = required pump capacity (gpm) p = required pressure (psi)
PURPOSE: To provide the horsepower control device of a hydraulic pump capable of effectively utilizing the horsepower of a prime mover nearly in the whole region regardless of a mechanical regulator provided on it.TOMIKAWA OSAMU富川 修HIRATA TOICHI平田 東一GOTO YASUHARU後藤 安晴...
Horsepower required by a hydraulic pump can be calculated as PHP = q p / 1714 (1) where PHP = horsepower (HP) q = flow (gpm) p = required pressure (psi) 1 gpm (US) =6.30888x10-5m3 /s = 0.227 m3 /h = 0.06309 dm3 (litre)/s = 2.228x10-3 ft3 /s = 0.1337 ft3 /...
摘要: PURPOSE: To provide a horsepower control device for variable displacement oil hydraulic pump wherein a several number of hydraulic actuators of differently setting a relief valve can be economically driven by enabling a cut off function to change in two steps as necessary....
Although the field electrician will normally never run this type of test, the formula is useful for determining the motor horsepower required to drive a known load. Also, the illustration is very useful in helping one visualize the changing of electrical energy into mechanical energy. Using the ...
If this operator is not used, the amount of pressure oil ejected from the first pump (1) and the second pump (2) is different,Will machine the most efficient hydraulic pump horsepower control system.The water pump's tilt plate (13, 14) adjusts the angle of the fourth version of the ...
PURPOSE:To make it possible to carry out a high-speed turn of a working vehicle having travelling hydraulic motors as its drive power source, by providing such a horsepower control device that high pressure may be cut-off from the side of nondriven hydraulic motor to a control means on the...
