Abstract
The utility model discloses a magnetic drive type gear pump which comprises a magnetic drive box, a pump shell, a transmission shaft, a driving gear and a driven gear, wherein the transmission shaft is arranged in the pump shell, the driving gear and the driven gear are meshed with each other, and the driving gear is installed on the transmission shaft. A magnetic drive wheel is arranged at one end, penetrating through the pump shell and stretches into the magnetic drive box, of the transmission shaft. A magnetic ring is arranged in the magnetic drive wheel. The magnetic drive type gear pump is characterized in that a thermal insulation shell is arranged on the pump shell, a thermal insulation cavity is formed by the pump shell and the thermal insulation shell, and the thermal insulation shell is filled with heating media. An impeller is arranged on the end portion of one end, stretching into the magnetic drive box, of the transmission shaft. Due to the fact that the structure is adopted, the problems that materials which are conveyed by a magnetic drive gear pump are affected by external temperature so that the viscosity is increased or coking and hardening occur are prevented. In addition, the problems that the materials which are conveyed by the magnetic drive gear pump enter the magnetic drive box and fall into the magnetic drive wheel so as to be hardened and cause clamping of the pump are avoided.
Description
Technical field
The utility model relates to a kind of gear pump, specifically a kind of magneto drive type gear pump.
Background technique
Existing gear pump driven by magnetic force is because its reliable conveying capacity generally is used for carrying the material of easy coking sclerosis under the normal temperature such as the larger resin of some ratios of viscosities, pitch.But the material of these easy coking sclerosis that gear pump driven by magnetic force is carried, be easy to be subject to the impact of external temperature, if external temperature is on the low side, the viscosity of the fed sheet of a media in the gear pump driven by magnetic force will increase so, even slight situation of hardening can appear, in case this situation occurs, so that gear pump driven by magnetic force conveying capacity to material in the situation of normal operation descends, even affect the normal operation of gear pump driven by magnetic force, had a strong impact on the normal operation of gear pump driven by magnetic force.When gear pump driven by magnetic force is carried the liquid that some contain magnetic substance, magnetic substance can flow in the magneto drive case with the transmission shaft that the magneto drive wheel links to each other along with driving gear, these magnetic substances can be attached on the magneto drive wheel, time has been grown, vibrations can appear in the magneto drive wheel in rotation, even stuck, thereby cause gear pump driven by magnetic force not turn round normally.
The model utility content
Technical problem to be solved in the utility model provides the magneto drive type gear pump of a kind of long service life, stable work in work.
To achieve these goals, the technical solution adopted in the utility model is:
Magneto drive type gear pump, include transmission shaft and intermeshing driving gear and driven gear in magneto drive case, pump case and the pump case, driving gear is installed on the transmission shaft, and an end of transmission shaft passes described pump case and is deep in the magneto drive case, and this end is provided with the magneto drive wheel; Be provided with magnet ring in the magneto drive case, it is characterized in that: be provided with heat-preservating shell on the described pump case, described pump case and described heat-preservating shell form incubation cavity, are full of thermal medium in this incubation cavity; The end that described transmission shaft is deep into the end in the described magneto drive case is provided with impeller.
Also be provided with seal ring between described transmission shaft and the pump case.
Described thermal medium is water vapour or conduction oil.
The end of described magnet ring also is provided with radiating fin.
The beneficial effects of the utility model: owing to established heat-preservating shell in the outside of pump case, and in incubation cavity, be filled with thermal medium, realized the heat tracing to the medium of carrying in the pump case, prevented that material that gear pump driven by magnetic force carries from increasing or occurring the problem of coking sclerosis because of the impact viscosity that is subjected to external temperature; Owing to set up impeller, after entering in the magneto drive case, drops on the material of having avoided the magnetic drive gear pump to carry the problem that produces holddown after the magnetic drive wheel upward hardens; Owing between pump case and transmission shaft, be provided with seal ring, prevent that the material of carrying from entering into the magneto drive case along the pump case inner pinion gear with the transmission shaft that the magneto drive wheel links to each other, thereby prevented that gear pump driven by magnetic force from entering into the problem that causes the magneto drive wheel not rotate after the coking sclerosis in the magneto drive case; Owing to be provided with radiating fin at magnet ring, realized that gear pump driven by magnetic force can dispel the heat better, has reduced the radial dimension of gear pump driven by magnetic force.
