A pump body annular heater for solving the problem of suspended semi submersible vertical turbine pump being unable to pump water due to icing

A pump body annular heater solves the problem that the suspended semi-submersible vertical turbine pump cannot complete the pumping work due to freezing. The pump body annular heater is installed in the pump shaft area of the vertical suspended semi-submersible vertical turbine pump to solve the problem of the vertical suspended semi-submersible vertical turbine pump being unable to pump water due to easy freezing in winter. question. A pump body annular heater includes a heater shell; it is characterized in that locking pins and locks are provided on the surface of the heater shell, and an adjustment ring is provided on the inner layer of the heater shell. The beneficial effect of this technical method is: this product adopts a semicircular structure for cold winter environments. 

The electric heater commonly used in industry is designed into a semicircular split structure surrounding the pump shaft area, and is made of corrosion-resistant stainless steel. To make the heater shell, the internal heating tube is also made of stainless steel, ensuring that it can still work smoothly even when the temperature is very low in winter, ensuring the insulation work of the suspended semi-submersible vertical turbine pump, and solving the problem of suspension The problem of the semi-submersible vertical turbine pump being unable to complete the pumping work due to freezing Technical requirements: 1. A pump body annular heater, including a heater shell; characterized in that the heater shell surface is respectively provided with locks Nails and locks, the inner layer of the heater shell is provided with an adjustment ring, the adjustment ring is provided with an adjustment knob, the adjustment knob passes through the heater shell and protrudes from the heater shell, and the inner layer of the adjustment ring is provided with There is a heating layer, a heating tube is provided on the heating layer, and an electrical contact is provided on the top of the heating tube.
