摘要: A closed-loop system (10) includes a pump (8) driving a fluid through a series of conduits (44). A control system (52) is included that minimizes pressure fluctuations in a bootstrap reservoir (20) to maintain a desired minimum pressure at the pump inlet (32). Moreover, the control system (52) reduces a maximum system pressure by reducing the magnitude of pressure fluctuations encountered by the bootstrap reservoir (20).

摘要: A water pump with a built-in battery includes a pump body. A battery compartment and a mounting cavity arranged in a horizontal direction and adjacent to each other are provided in the pump body. A water inlet and a water outlet are further formed in the pump body. A control panel is provided at an upper part of the mounting cavity. A battery pack is detachably connected into the battery compartment, and an upper part of the battery compartment is detachably connected to a battery compartment cover. A handle is provided on the battery compartment cover. A motor is provided in the mounting cavity. The control panel is electrically connected to the battery pack and the motor. When the water pump is in use, a junction between the battery compartment and the battery compartment cover is located an upper part of the pump body, and the battery pack does not exert a force on the battery compartment cover, thereby preventing a liquid from penetrating into the battery compartment, and improving the sealing performance inside the pump body.

摘要: An automatic pump protection system is comprised of a plurality of sensors for measuring process parameters indicative of a loss of pump suction or of pump motor failure. Analysis of the parameters is performed by a microprocessor in order to determine whether conditions leading to a loss of pump suction or pump motor failure are present. The microprocessor then automatically initiates pump protective action in response to the foregoing analysis by tripping the pump or by providing an alternate suction source.
