进口高温双螺杆泵Product description:

The twin-screw pump is connected to the explosion-proof motor through the coupling and powered by the explosion-proof motor; The outer surface of the shell of the twin-screw pump is provided with a thermal insulation shell with a cavity, and the thermal insulation shell is provided with a steam inlet and a steam outlet which are connected with the cavity. The high-temperature twin-screw strong self-priming liquid sulfur pump, based on its own good self-priming performance, ensures the temperature of the medium "liquid sulfur" by using the function of injecting steam into the cavity structure of the insulation shell, so as to ensure the normal operation of the twin-screw pump.

进口高温双螺杆泵characteristic:

It is a solid at room temperature. When the temperature of sulfur reaches the melting point, the sulfur will melt into liquid sulfur with flowing properties. The viscosity of molten sulfur changes with the temperature. Generally, the viscosity of molten sulfur decreases with the increase of temperature during initial melting. When the temperature exceeds 159 ℃, the viscosity increases sharply with the increase of temperature. When the temperature continues to increase to 190 ℃, the viscosity of sulfur reaches the maximum. When the temperature exceeds 190 ℃, the viscosity returns to its original characteristics. At 130160 ℃, the viscosity is the minimum, which is conducive to the transportation of liquid sulfur. Once the pump is stopped, the sulfur in the pipeline and pump will condense in the pump and pipeline due to the temperature drop, which will make it difficult to start the pump again and damage the mechanical seal. Because of its special physical characteristics, the transportation of liquid sulfur has always been a difficult problem. At present, the commonly used delivery pump is the long shaft submerged pump. When the pump is started, the impeller has been immersed in the medium, so it is easy to start. It will not be difficult to operate because the medium temperature is not within the optimal temperature range, and it is widely used without considering the problem of self-priming height. However, it is inconvenient to maintain the long shaft submerged pump, and the sliding bearing is easy to be corroded and worn. In addition, once the sliding bearing is dry ground, there is a great potential safety hazard. The pump shaft has a large vibration swing and is vulnerable to medium corrosion, with a high failure rate.

进口高温双螺杆泵Principle:

Before starting the high-temperature twin-screw strong self-priming liquid sulfur pump, apply high-temperature steam to the insulation shell 8 of the high-temperature twin-screw strong self-priming liquid sulfur pump or adjust the temperature of the electric tracing coil 9=through the electric control box to preheat the pump chamber, so as to prevent the medium "liquid sulfur" from suddenly entering the lower temperature pump chamber to solidify, affecting the normal operation of the pump. At the same time, start the temperature sensor 10 through the electric control box. If the temperature does not meet the requirements of the insulation chamber, send an alarm signal, After preheating for 20-30 minutes, the temperature reaches the required temperature, the alarm signal stops sending, the explosion-proof motor starts, drives the high-temperature twin-screw strong self-priming liquid sulfur pump to rotate, and the medium "liquid sulfur" is sucked into the pump chamber of the high-temperature twin-screw strong self-priming liquid sulfur pump through the inlet pipeline. The pump chamber temperature is now heated by steam, and has reached the temperature condition for the normal transmission of the medium "liquid sulfur", The medium "liquid sulfur" enters the outlet pipeline through the outlet of the screw pump, and then is transported to the designated place.
