Abstract

The invention makes it possible to increase the reliability and service life of the pump by increasing the stability of the installation and supplying water with a reduced content of suspended matter to the pump. On the pontoon 1 catamaran type a submersible pump 2 is installed with an intake of 3 liquids. 4,5 pontoons are fastened to pontoon 1 in the form of a rectangular frame. Two transverse vertical partitions 6,7 are located with the formation of three compartments below the liquid level. Pump 2 with intake 3 is installed in compartment 8, which is made closed at the bottom. To prevent large inclusions from entering, the water velocity must be less than the critical velocity. Fencing installations are located in the extreme compartments. 1 hp f-ly, 2 ill.

This invention relates to floating pump installations with submersible pumps.

The purpose of the invention is to increase the reliability and service life of the pump by increasing the stability of the installation and supplying the pump with water with a reduced content of suspended matter.

Fig. 1 schematically shows a floating pumping installation, a longitudinal section; figure 2 is the same, top view.

The floating installation contains a pontoon 1 of a catamaran type and a submersible pump 2 installed on it with an intake of 3 liquids, the installation is equipped with two additional pontoons 4 and 5 fastened with a catamaran pontoon 1 in the form of a rectangular rim and two transverse vertical partitions 6 and 7 located with the formation of three compartments below the liquid level, while the pump 2 with the intake 3 is installed in the middle compartment 8 and the latter is closed at the bottom. The installation is equipped with fish-protecting installations. Hey 10, located in the extreme compartments 11 and 12.

The pump installation works as follows.

Raising from the bottom upwards through the extreme open compartments 11 and 12 and the fish farm, the radar installations 9 and 10, the water, standing up by gravity, flows through partitions 6 and 7, whose height is lower than the water level in the reservoir, into the middle

the closed compartment 8 and the pump 2 with the intake 3 are supplied to the discharge line.

To prevent large inclusions, debris, and sediment from entering the pump, the water velocity must be less than the critical velocity. To do this, the dimensions of the extreme compartments are chosen according to the capacity of the pump.
