  • Patent number: 10704546
    Abstract: A service module for troubleshooting a pumping unit, particularly that used in the oil/gas industry, is operatively coupled between a motor of the pumping unit and a high pressure shutoff sensor which acts to kill the motor of the pumping unit in the event a pressure of the pipeline exceeds a prescribed threshold. The service module is operable in a first normal operating mode in which the shutoff sensor acts as it normally would to shut off the motor when the prescribed threshold is exceeded, and in a second troubleshooting mode where the normal operation of the shutoff sensor is bypassed for a predetermined period of time. After the predetermined period of time of the second troubleshooting mode has elapsed, the service module automatically returns to the normal operating mode. The shutoff sensor thus remains operatively coupled to the motor during troubleshooting of the motor.

  • Patent number: 10704545
    Abstract: An electric inflator for connecting and inflating an inflatable device includes a shell, a drive motor configured on the axis of the shell, at least one air bag is configured in the shell and around the drive motor, an air outlet of the air bag connected to an inflatable device, and a pressing mechanism connected to an output portion of the drive motor. The air bag is pressed by the pressing mechanism driven by the drive motor for supplying air to the inflatable device. An inner space of the shell can be fully utilized thereby the size of the electric inflator is smaller than before. At the same time, an inner cavity of the air bag can be bigger than before to improve inflating efficiency, which increases portability and practicability of the electric inflator and the inflatable device equipped with the electric inflator.

  • Patent number: 10670006
    Abstract: A peristaltic pump comprises a drive assembly, a hose pump, and a hose bracket. The drive assembly is rotatably disposed within a frame to move a roller along a pumping path with respect to the frame. The pump hose has rigid hose ends connected by a bendable hose section with limited flexibility tending to bias the pump hose towards a substantially unbent shape. The hose bracket has a rigid body with a first central opening sized to receive the rigid hose ends at first and second retention locations, such that the natural bias of the pump hose towards a substantially unbent shape retains the hose ends within the first and second retention locations, positioning the bendable hose section along the pumping path of the roller.

  • Patent number: 10598162
    Abstract: A pump in desalination systems has four cylinders, each having a double acting piston. Each cylinder and piston defines a feed chamber and a recovery chamber. The pistons connect to a common drive. The connection to the common drive is such that the pistons reciprocate in a sequence equally spaced in time. Reciprocating valving for each piston is driven by the common drive to be 90 degrees out of phase with the respective piston. The valving connects the recovery chamber alternately to an inlet manifold for an intake stroke of the piston relative to the recovery chamber, and to an outlet manifold for a discharge stroke of the piston relative to the recovery chamber. A brief period of closure coincides with top dead centre and bottom dead centre of the piston, during which the recovery chamber is blocked off from both the inlet and outlet manifolds. The reciprocating valving is midway between its top dead centre and bottom dead centre during the period of closure.
