What is the principle of automatic coupling device of submersible sewage pump

How it works and its advantages

The automatic coupling device of the sewage pump is a device used together with the sewage pump. It is mainly composed of a submersible sewage pump, an automatic coupling device and a water outlet pipe assembly. The automatic coupling device is installed between the submersible electric pump and the sewage outlet pipe, and the automatic coupling device is installed in the sewage pump. The advantage of the device is that it is convenient for the pump to be picked and placed and repaired in the event of a failure. The auto-coupling device is suitable for long-term fixed use occasions. The system uses a special base, which is fixed at the bottom of the sewage pit, and is connected with the outlet pipe. A supporting block is installed on the top of the pool, and the two are connected by a guide rod. The water pump is connected with a specific bracket, slides down to the base along the guide rod, is automatically coupled and sealed with it, and automatically falls off when it is lifted.

  The principle of the automatic coupling device of the submersible sewage pump: there is a pair of wedge clips above the additional coupling flange of the automatic coupling device and the inlet flange of the outlet pipe seat, and there is a pair of wedge clips below the additional coupling flange and the inlet flange of the outlet tube seat , A wedge under the inlet flange of the outlet pipe seat is fixed under the inlet flange of the outlet pipe seat with elastic steel plate. When the submersible pump descends from the top of the puddle, the wedge clip above the additional flange flange and the wedge clip above the inlet flange of the outlet pipe seat are clipped together first. The flange faces will stick together, and a pair of wedge clamps under the additional coupling flange and the inlet flange of the outlet pipe seat will also be automatically clamped together under the action of the elastic steel plate. It can solve the problem of a large amount of water leakage between the two coupled flanges while facilitating the automatic assembly and disassembly of the submersible electric pump, thereby saving energy.

 In addition, the use of the automatic coupling device can save a lot of processes and shorten the maintenance time when the Macerator pump fails. For example, it is not necessary to disassemble the pipeline, and the pump can be lifted up from the water along the slideway through the zipper for maintenance, and the maintenance is over. Then, put it underwater along the slideway. After the pump is in place, the water outlet of the pump will be well connected with the inlet of the water outlet under the action of the self-coupling device and automatically locked.
