Multi-stage pump, GDL vertical multistage booster pump head, GDL vertical multistage booster pump applications

Multi-stage pump, GDL vertical multistage booster pump head, GDL vertical multistage booster pump applications Introduction: GDL pressurized multistage centrifugal pump Aobang reference to the design and manufacture of advanced foreign products. Impellers, vanes and diversion shell made of stainless steel sheet metal stamping, drawing, welding molding, using carbide mechanical seal and guide bearing. Small size, light weight, high efficiency, energy saving, low noise and smooth operation, long life, vertical installation, small footprint, light weight and notable features beautiful appearance, is the ideal replacement products. Features: 1, GDL pressurized multistage centrifugal pump for the vertical structure, with a small footprint features, pump pump foot center coincides with the center of gravity, thus smooth running, small vibration, long life. 2, GDL multistage centrifugal supercharger same caliber and the center line at the same level, without changing the pipeline structure, can be directly installed in any part of their pipes, the installation is very easy. 3, the motor plus rain cover can be placed directly outdoor use, and without the construction of pumping stations, significant savings in capital investment. 4, GDL head multistage centrifugal supercharger can be meet different requirements by changing the pump stages (impellers number), so for a wide range. 5, seal with carbide mechanical seal, reliable seal, no leakage, no mechanical losses. 6, energy efficient, beautiful appearance. 7, injection molded castings more than 50 caliber. Usage: GDL multistage centrifugal supercharger is especially suitable for boiler feed water, it can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, irrigation, fire booster, water washing, food, brewing, pharmaceutical, chemical, aquaculture, environmental protection, chemical processes and tools supporting other industries, as the driving force of the water supply and drainage equipment. Conditions of Use: 1, used to transport water or physical and chemical properties similar to liquid water; 2, transmission fluid should be no solid particles, no fiber, no strong corrosive, non-explosive; 3, the maximum liquid temperature does not exceed 120 ℃ ; 4, the maximum working pressure does not exceed 2.5MPa; 5, the power supply for 3-phase 380V, 50HZ. Voltage fluctuations within ± 5%; 6, the ambient temperature should be below 40 ℃, relative humidity less than 95%. Installation instructions: 1, the installation of the pipeline should not bear weight on the GDL vertical centrifugal pumps, or fragile ring GDL vertical centrifugal pumps; 2, multi-stage centrifugal pump motor is the overall structure of Joseph, by the manufacturers factory correction, so the installation without having to adjust, so very easy to install; 3, before installing the pump should be carefully examined GDL Multistage Pump runner whether the impact of a hard object pump operation, (such as rocks, iron ore, etc.) in order to avoid the pump running Loss also flow components; 4, installation into must tighten the bolt, and each time interval of one fact respond pumped through the line checking to prevent it from loosening, so as to avoid excessive vibration occurs when pump start to affect performance; 5, in order to facilitate maintenance and safe to use, import and export pipeline pump installation of a valve and a pump installed in the vicinity of the import and export of a pressure gauge, for high-lift, in order to prevent water hammer, but also in front of the outlet of a check valve installed to meet sudden power outages and other accidents lost power to ensure the pump is running at optimal conditions, increase pump life; 6, multistage centrifugal pump has a suction lift for the occasion, should be equipped with a foot valve and inlet pipeline should not There are too many corners, but may not have leaks, air leaks, so as not to affect the performance of the pump suction; 7, in order not to impurities entering the pump and block the flow path affect performance, the filter should be installed in front of the pump inlet; 8, installation front line rotation of the pump rotor parts, there should be no friction sound or stuck phenomenon, otherwise the pump should be open inspection reasons. GDL multistage centrifugal supercharger start and stop: before starting to prepare a hand pull turn coupling, the impeller should be no card wear phenomenon, flexible rotation; 2, open the inlet valve, opening the exhaust valve so that the liquid fills the pump chamber and closing the exhaust nozzle; 3, such as the transmission of hot liquid, should be preheated before starting a heating rate of 50 ℃ / h, preheat the pump is delivered continuously circulating liquid to achieve, so that each part of heated evenly; 4, it should move hand drive pump a few times so that the lubricating water into the mechanical seal face; 5, to move the motor rotation is correct indeed. Starting with the run, and fully open the inlet valve, close the discharge piping door; 2, power on, when the multi-stage pump up to speed, and gradually open the valve on the discharge pipe, and adjusted to the required conditions; 3, note observe the meter reading, check the seal leaks, the normal time to drain the mechanical seal leakage 3 / min, check the motor, the bearing temperature ≤70 ℃, if unusual circumstances, should be promptly treated. Parking 1, gradually close the discharge line valves; 2, close the inlet valve; 3, such as ambient temperature than 0 ℃. Liquid inside pump should be exhausted in order to avoid the cracking water pump; 4, such as long-term disabled, the pump should be removed for cleaning, packaging, storage. GDL multistage centrifugal supercharger Maintenance: Maintenance Operation and maintenance 1, the inlet pipe must be highly sealed and not leaking gas leakage; 2, the long-running ban multistage centrifugal pump cavitation in the state; 3, prohibited multistage centrifugal pump running high flow conditions, the motor over current long-term operation; 4, regularly check the current value of the multi-stage centrifugal motor running, try to run the pump within the design range of operating conditions; 5, multi-stage centrifugal pumps In operation should be supervised to avoid accidents; 6, multistage centrifugal pump bearings every 500 hours to deal with refueling; 7, multistage centrifugal pump for long-term operation, due to mechanical wear and tear, the unit increased noise and vibration, should stop and check, if necessary, replacement of wearing parts and can enter the bearing, unit overhaul period is generally one year. Maintenance of the mechanical seal 1 mechanical seal lubricating fluid should be clean and free of solid particles; 2, non-mechanical seal in case of dry grinding; 3, before starting the pump should Barring (motor) a few times, so as to avoid sudden start caused by mechanical seal Fracture damage.
