Hermetically sealed centrifugal pumps for the petroleum, heavy chemical and natural gas industries 3 Terms and Definitions GB / T 7021, GB / T 25140 defined terms and definitions apply to this document. 4 type and basic parameters 4.1 type 4.1.1 magnetic pump for a single, single suction horizontal. 4.1.2 Magnetic pump inlet for the axial suction, the outlet is up to the discharge, the pump and motor to magnetic coupling (that is, the combination of internal and external magnet) power transmission. 4.1.3 The magnetic pump is divided into CQ series magnetic pump and CQB series magnetic pump. According to the overcurrent component materials and applicable temperature, CQB series magnetic pump is divided into CQB series of room temperature metal magnetic pump (referred to as metal magnetic pump) and CQB series of room temperature fluorine plastic magnetic pump (referred to as fluorine plastic magnetic pump) and CQB series of high temperature metal magnetic force Pump (referred to as high temperature magnetic pump), the typical structure shown in Figure 1, Figure 2, Figure 3, Figure 4 shows.
Example 1: CQB50-32-160, said the import diameter of 50 mm, the outlet diameter of 32 mm, the nominal diameter of the impeller is 160 mm, pump, impeller and other overcurrent components for the metal material for temperature CQB series of magnetic centrifugal pumps (metal magnetic pump). Example 2: CQB50-32-160G, said the import diameter of 50 mm, the outlet diameter of 32 mm, the nominal diameter of the impeller is 160 mm, pump, impeller and other overcurrent components for the metal material for the temperature of the CQB series of magnetic centrifugal pumps (high temperature magnetic pump). Example 3: CQB50-40-125F, said the import diameter of 50 mm, the outlet diameter of 40 mm, the nominal diameter of the impeller 125 mm, pump body, impeller and other over-current components for the fluorine plastic, suitable for temperature CQB series of magnetic centrifugal pump Fluorine plastic magnetic pump). 4.3 Basic parameters 4.3.1 The basic parameters of the magnetic pump should be consistent with Table 1, Table 2, Table 3 provides the values listed.
