Abstract
The utility model relates to a kind of Insulation Shell of Magnet Pump, is specifically related to a kind of Double-layered isolation casing of fluoroplastics lining magnetic drive pump.The utility model comprises outer separation sleeve, is arranged on the internal layer separation sleeve in outer separation sleeve, the base plate of described internal layer separation sleeve is provided with cavity, is provided with inserts in described cavity; The utility model by arranging inserts on the base plate of internal layer separation sleeve, adds the intensity of internal layer separation sleeve base plate, ensure that internal layer separation sleeve base plate strength under negative pressure condition, prevents the damage of internal layer separation sleeve.
Description
Technical field
The utility model relates to a kind of Insulation Shell of Magnet Pump, is specifically related to a kind of Double-layered isolation casing of fluoroplastics lining magnetic drive pump.
Background technique
Fluoroplastics lining magnetic drive pump, in order to improve the intensity of separation sleeve, increases its corrosion resistance simultaneously, is usually designed to double-deck, internal layer separation sleeve is anticorrosive coat, be made up of the good perfluoroethylene-propylene of corrosion resistance, outer separation sleeve is reinforced layer, is made up of the plastics of the high strength such as carbon fiber or PEEK; In order to reduce magnetic gap, improve Magnetic drive efficiency, internal layer separation sleeve wall thickness is generally 2-3mm, and outer separation sleeve wall thickness is generally 4-5mm, and normal situation can meet applying working condition, but when negative pressure, the base plate of internal layer separation sleeve can cave inward, and contacts with inner magnet rotor of magnetic drive pump, damages internal layer separation sleeve, thus separation sleeve was lost efficacy, and leak.
Model utility content
The purpose of this utility model has technology Problems existing to provide a kind of Insulation Shell of Magnet Pump for receiving.
A kind of Double-layered isolation casing for magnetic pump, comprises outer separation sleeve, is arranged on the internal layer separation sleeve in outer separation sleeve, the base plate of described internal layer separation sleeve is provided with cavity, is provided with inserts in described cavity;
Described inserts is provided with through hole;
Described inserts is hard disk;
Described outer separation sleeve base plate is provided with stiffening rib;
Described outer separation sleeve base plate is bolted in inserts.
The utility model has following beneficial effect:
1. the utility model by arranging inserts on the base plate of internal layer separation sleeve, adds the intensity of internal layer separation sleeve base plate, ensure that internal layer separation sleeve base plate strength under negative pressure condition, prevent the damage of internal layer separation sleeve;
2. inserts of the present utility model is provided with through hole, under negative pressure condition, the base plate of internal layer separation sleeve caves inward, and the floor portion of internal layer separation sleeve is absorbed in through hole, ensure that the circumference of internal layer separation sleeve and inserts is fixed;
3. outer separation sleeve base plate of the present utility model is provided with stiffening rib, further enhances the intensity of outer separation sleeve base plate;
4. outer separation sleeve base plate of the present utility model is bolted and inserts, improves the join strength of outer separation sleeve and internal layer separation sleeve;
5. the utility model structure is simple, easy to manufacture, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
a kind of Double-layered isolation casing for magnetic pump as shown in Figure 1, comprise outer separation sleeve 1, be arranged on the internal layer separation sleeve 2 in outer separation sleeve 1, the base plate of described internal layer separation sleeve 2 is provided with cavity 3, be provided with inserts 4 in described cavity 3, described inserts 4 is provided with through hole 5, described inserts 4 is hard disk, described outer separation sleeve 1 base plate is provided with stiffening rib 6, and described outer separation sleeve 1 base plate is connected to inserts 4 by bolt 7.
When magnetic drive pump produces negative pressure, the base plate of internal layer separation sleeve 2 is subject to inside power, and inserts 4 pairs of internal layer separation sleeves 2 support, and ensure that internal layer separation sleeve 2 can not cave inward, prevent the damage of internal layer separation sleeve 2; Simultaneously under negative pressure condition, the floor portion of internal layer separation sleeve 2 is absorbed in the through hole 5 of inserts 4, ensure that internal layer separation sleeve 2 is fixed with the circumference of inserts 4; Outer separation sleeve 1 base plate is connected to inserts 4 by bolt 7, improves the join strength of outer separation sleeve 1 and internal layer separation sleeve 2; Outer separation sleeve 1 base plate is provided with stiffening rib 6, further enhances the intensity of outer separation sleeve 1 base plate.
