A pump head fixing device for a vertical long axis semi submersible Suspended sump pump

The pump head fixing device of a vertical long axis semi submersible sump pump includes a pump body, an inlet pipe, a connecting plate, a fixing plate, a base, screws, bolts, a base, and a liquid tank. The inlet pipe is fixed to the lower part of the pump body, the connecting plate is fixed to the lower end face of the inlet pipe, and a fixing plate is welded to the lower end face of the connecting plate. The fixing plate is conical in shape and gradually decreases in diameter from top to bottom. The base is installed on the bottom face of the liquid tank through surface bolts, and the base is fixed in a ring shape on the upper end face of the base. The top inner ring of the base is provided with a sloping surface that matches the fixing plate, and the fixing plate is embedded into the inner ring. At the top of the base, four screws are fixedly attached to the upper end surface of the base, which are respectively set at the four quadrant points of the upper end surface of the base. The connecting plate is perforated, The bolt passes upward through the connecting plate and is fitted with a bolt at the top of each bolt. This technical method has the advantages of stable operation and long service life.

[Technical Introduction]

The working part of the vertical semi submersible Suspended sump pump is submerged inside the liquid, which has the advantages of small footprint, reliable use, easy maintenance, and strong corrosion resistance. It is widely used in industrial sectors such as chemical, chemical, papermaking, and petroleum industries. In certain specific situations, such as deep underwater conditions, a vertical long axis semi submersible sump pump is required. During installation, the pump head is generally suspended on the pump base plate through the pump base plate. Due to the deep underwater depth, the pump head is in a long cantilever state for a long time. When the pump is started, the centrifugal force caused by the impeller rotation also causes significant oscillation of the pump head. Long term operation can cause damage to the pump body and low service life.

Technical implementation ideas

The pump body is installed inside the liquid tank, the inlet pipe is fixed to the lower part of the pump body, the connecting plate is fixed to the lower end face of the inlet pipe, and a fixing plate is welded to the lower end face of the connecting plate. The fixing plate is in the shape of a circular truncated cone, and the diameter gradually decreases from top to bottom. The base is installed on the bottom face of the liquid tank through surface bolts, and the base is fixed in a ring shape on the upper end face of the base. The top inner ring is equipped with a sloping surface that matches the fixed plate. The fixed plate is embedded in the top of the base, and four screws are fixed to the upper end surface of the base, which are respectively set at the four quadrant points of the upper end surface of the base, The connecting plate has holes, and the bolts pass upward through the connecting plate, with one bolt inserted at the top of each bolt. The center of the connecting plate and the fixed plate are respectively provided with inner holes, and the two inner holes are concentric and of the same diameter. There are through holes on the periphery of the base for fluid to enter.
