_ Puhou pipeline pump pipeline pump Vertical Pump Figure _isg80125

Pipeline pump is single stage single suction centrifugal pump one, is a vertical structure, its import and export in the same straight line, and the import and export of the same caliber, rather like the section of pipe, the pipe can be installed at any location in the so named for the pipeline pump, also known as booster. Structural characteristics of single-stage single-suction centrifugal pump, it's the same and in the same line, and the axis perpendicular to the centerline, the vertical pumps. The basic structure of the pipeline pump is composed of six parts are the impeller, pipeline pump, shaft, bearings, seal rings, stuffing box. The basic structure of the pipeline pump is composed of six parts are the impeller, pipeline pump, shaft, bearings, seal rings, stuffing box. In accordance with the installation it can be divided into vertical and horizontal pipeline pump pipeline pump. Universal letter ISG and ISW 1, centrifugal impeller is the core part, it speed up force, the impeller blades and played a major role in the assembly before the impeller by static test. Requirements on inner and outer surfaces of the impeller smooth to reduce flow friction losses. 2, pipeline pump, also known as the pump casing, which is the main water pump. Fixed play a supporting role, and connected to the installation of the bearing bracket. 3, the role of the pipe shaft is connected by means of coupling and motor, the motor torque transmitted to the impeller, so it is the transmission of the main components of mechanical energy. 4, the support shaft bearing is set in the shaft member, there are two kinds of rolling bearings and plain bearings. Pump bearing temperature during operation up to 85 degrees generally run at about 60 degrees, if necessary to find the cause of high and timely manner! 5, sealing ring, also known as Save the drain ring. Too gap caused by the impeller inlet and pump water into the pump housing between the high pressure region through the gap of the low pressure area, the impact of pumping capacity, reducing efficiency! Gap is too small will cause the impeller and pump casing friction wear. In order to increase the resistance to reduce leakage reflux, delayed impeller and pump housing that life, with sealing ring in the pump casing and impeller foreign aid junction edge. 6, stuffing consists of packing, lantern ring, packing tube, packing gland, seal tube. Role stuffing mainly to closed the gap between the casing and the shaft, to prevent the water within the pump does not flow out to not let the outside air into the pump. Always keep the vacuum pump inside! When the shaft and packing friction heat to rely on the seal to seal the circle take control of water to cool the filler! Maintain the normal operation of the pump. So the pump running roving inspection process checks for stuffing particularly pay attention! Running 600 hours or so should be replaced on the filler. Features: 1, the pump for the vertical structure, import and export of the same caliber, and in the same center line, as the valve installed in the pipeline, compact appearance, small footprint, low construction inputs, such as with protection cover can be placed outdoors. 2, the impeller mounted directly on the motor shaft extension, the short axial dimension, compact structure, pump and motor bearing configuration is reasonable, can effectively balance the radial and axial loads generated by operation of the pump, thus ensuring the smooth operation of the pump, low vibration and noise. 3, seal with mechanical seal or a combination of mechanical, using imported titanium alloy seal ring, medium and high temperature mechanical seal with carbide materials, wear-resistant seal, can effectively increase the mechanical seal life. 4 Easy installation and maintenance, without the need to open pipeline system, as long as remove the pump nut seat body out all the rotor components. 5, flow and head of the need to use requires Ga series and parallel operation mode. 6, can use the vertical and horizontal pumps installed according to requirements of piping layout.
