  • Patent number: 9816508
    Abstract: A dry-type cable wire outlet device for a submersible electrical pump includes a wire outlet box positioned in a wellbore, a cable protection pipe, a wire outlet sealing device and a cable. The wire outlet box is connected to the top of a submersible electrical pump. One end of the cable protection pipe is connected to the top of the wire outlet box, and the other end extends out of the well cover of the wellbore. The cable is positioned in the cable protect pipe and connected with the submersible electrical pump through the wire outlet box. The wire outlet sealing device is connected to the well cover, and an end of the cable protection pipe extending outside the well cover is positioned in the wire outlet sealing device. When the device is in use, the opening at the top end of the cable protection pipe is no longer exposed.

  • Patent number: 9255577
    Abstract: Disclosed is a large-scale submersible sewage pump assembly that includes a pump and a pump seat installation structure, wherein the pump seat installation structure has a concrete installation base layer, and a pump seat for installing the pump. The pump seat is fixed to the pump installation layer, and the bottom of the pump is directly connected onto the pump seat. The pump has a motor cooling apparatus, wherein the cooling apparatus has an internal cooling apparatus installed inside the case of the motor, and an external cooling apparatus installed outside the motor. The pump seat installation structure can stably mount and support the large-scale submersible sewage pump, preventing potential safety hazard during running of the pump.

  • Patent number: 9103452
    Abstract: A large-scale hydraulic variable-speed floating box flap valve includes a hinge support, a valve seat, an upper valve leaf and a lower valve leaf, the valve seat and the hinge support are both fixed on a pump station base. The upper valve leaf is hinge-connected to the hinge support through a pin shaft, and the lower valve leaf is hinge-connected to the upper valve leaf. The upper valve leaf and the lower valve leaf may contact and match the valve seat in a sealed manner through a sealing structure. The upper valve leaf is connected to the lower valve leaf through at least one hydraulic mechanism. The hydraulic mechanism has one end hinge-connected to the upper valve leaf, and the other end hinge-connected to the lower valve leaf. The impact force between the valve leaves and the valve seat is damped by the hydraulic mechanism.
