Three, ISG vertical pipeline pump operating conditions a suction pressure ≤1.0MPa, or maximum working pressure pump system ≤1.6MPa, namely suction pressure + pump head ≤1.6MPa, hydrostatic test pump pressure ≤2.5MPa where stainless steel Well pumps, please specify when ordering system work pressure. 1.6MPa working pressure pump system should be greater than in the order presented separately, in order to manufacture the pump flow section and a coupling portion using steel materials. 2, ambient temperature <40 ℃, relative humidity <40%. 3, the transmission medium is not more than the volume content of solid particles per unit volume of 0.1, a particle size <0.2mm. NOTE: If with small particles, please when ordering by medium to factory using wearable mechanical seal. Four, ISG vertical pipeline pump Model significance For example: IRG50-160 (I) A ISG- Vertical single-stage pipeline pump IRG- vertical single-stage pump hot water pipes GRG- vertical single-stage pump hot water pipes stand IHG- single-grade stainless steel chemical pump YG- single stage single suction pipeline pumps 50- pump inlet and outlet nominal diameter (mm) 160- nominal outside diameter of the impeller (mm) I- traffic classification A- first cut impeller pump hot water pipes IR-type characteristics: 1, IR pump performance and size according to ISO2858 international standard design, mainly by the pump, pump cover, impeller, shaft, seal rings, bushings and suspension bearings and other components missing. 2, IR pump pump and pump cover part of the back office split from the impeller of the pump IHG50-250A pipeline corrosion, known as post-form door structure. Advantages of heat pumps are easy maintenance, repair does not move when the pump, suction pipe, exhaust pipes and motors, simply remove the extended intermediate connector couplings, you can exit the rotor parts repair. 3, IR pump housing (ie, pump and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings as the pump rotor. Suspension bearing components supporting the rotor of the pump, the rolling bearing by radial and axial forces of the pump. 4, IR pump in order to balance the axial force of the pump, before most of the pump impeller, has a rear seal ring, and the rear cover plate is provided in the impeller balance holes, due to some force not IHG50-250B shaft pipe pump, not the back of the impeller seal ring and balance holes provided. 5. IR axial pump seal ring is packing gland, packing rings and packing, etc., in order to prevent leakage into the air or a lot. If the pump impeller balance IR is fitted with soft packing cavity with suction impeller connected, such as a liquid in a vacuum impeller entrance pipeline pump, it is very easy along the surface of the intake sleeve, so the packing chamber equipped packing ring hole through the pump cover, the pump chamber pressure water lead to the packing ring seal. If there is no pump impeller balance holes, due to the back of the impeller fluid pressure greater than atmospheric pressure, and thus there is no leakage problems, it is time to install the packing rings. 6, IR pump shaft to avoid wear and tear, the axis through the packing chamber fitted sleeve to protect the site. O-ring between the quasi sleeve and the shaft to prevent along with the surface of the intake or leaking. 7, IR pump drive is through lengthened flexible coupling with the motor connected, the direction of rotation of the pump from the drive end, clockwise rotation.
