Abstract
The utility model relates to a double-layered isolating sleeve for a magnetic pump, which is composed of an inner layer and an outer layer. An annular cavity is formed between the outer layer and the inner layer, and the cavity is communicated with a detection hole on a flange of the isolating sleeve. The utility model has the advantage of simple structure. When the utility model is used, pressure gas or liquid is filled in the cavity between the outer layer and the inner layer, and thus, the user can detect whether the isolating sleeve is worn out by using a pressure meter or other pressure measuring devices arranged on the detection hole, so as to take measures early and avoid leakage accidents occurring.
Description
The utility model relates to the double-deck separation sleeve of a kind of magnetic drive pump
Magnetic drive pump is a kind of glandless motor pump, because of it has the incomparable sealability of axial seal class pump, so be widely used in industrial and mining enterprise such as oil, chemical industry, medicine, light industry, key equipment inflammable, explosive, hypertoxic as carrying, precious liquid; But, because the restriction of the transmission principle of magnetic drive pump own, be positioned at the separation sleeve that seals between inside and outside magnetic cylinder and need be designed to the thin-walled parts that wall thickness is 0.5-1.5mm, therefore, when pump operation, in some cases, magnetic cylinder deflection in heavy wear causes as bearing, medium contains solid grains such as catalyzer, sand, all might separation sleeve is worn out, cause more serious accident
The purpose of this utility model is to design a kind ofly by outer and be provided with the magnetic drive pump bilayer separation sleeve that the internal layer that detects the hole is formed for overcoming above-mentioned deficiency, and whether worn out, with timely processing, prevent leakage accident if can detect separation sleeve
The utility model content, the double-deck separation sleeve of magnetic drive pump be by internal layer and outer the composition, formation one toroidal cavity between skin and the internal layer, and this cavity is communicated with detection hole on the separation sleeve flange.
The skin of the double-deck separation sleeve of magnetic drive pump and the gap cavity size of internal layer are 0.2-1mm
The utility model advantage, the inside and outside layer of the double-deck separation sleeve of this magnetic drive pump constitutes the column toroidal cavity, this cavity is communicated with the detection hole, after charging into liquid or gas with certain pressure, whether internal layer or the skin that can measure separation sleeve with pressure gauge (or Other Instruments) are worn through, to remind the staff to handle early, it is simple in structure to avoid taking place leakage accident the utility model, is easy to make.
Description of drawings:
Fig. 1 is the utility model plan view;
Fig. 2 is the sectional view of Fig. 1;
Below in conjunction with the preferred embodiment of description of drawings the utility model, the double-deck separation sleeve of magnetic drive pump is made up of internal layer 1 and outer 4, internal layer and the outer cylinder that all is designed to have flange plate in the present embodiment, outer field flange plate is loaded in the hole on the internal layer flange plate, form a toroidal cavity between the two, weld at junction plane 3 places the assembling back.Need after the welding require weld seam pore-free and slit through pressure test, promptly guarantee water-tight air tightly, the external cylindrical surface of internal layer is concentric with the hole requirement on its flange plate, and outer field inner cylindrical surface should be concentric with the cylindrical of its flange plate; The flange plate of internal layer is provided with and detects hole 2, setting pressure table on this hole, detecting the hole communicates with the external cylindrical surface of internal layer and the spatia 5 between the outer field inner cylindrical surface, present embodiment is designed to 0.3mm with this spatia, in the use this spatia is charged into the pressurized gas or the liquid medium of 5 kilograms of pressure, can find that by the manometric variation in pressure that detects on the hole whether the internal layer of separation sleeve or skin are worn through so that the operator handles early, avoid taking place leakage accident
