Application and Fault Analysis of Pipeline Pumps

Features: 1, the pump is a vertical structure, import and export of the same caliber, and located in the same center line, can be installed in the pipeline like a valve, the shape is compact Beautiful, small footprint, low construction investment, such as with the protective cover can be placed outdoors. 2, the impeller is mounted directly on the motor shaft, the axial size is short, compact structure, the pump and motor bearing configuration is reasonable, can effectively balance the radial and axial load pump operation, thus ensuring the smooth operation of the pump, Small vibration, low noise. 3, shaft seal mechanical seal or mechanical seal combination, the use of imported titanium alloy seal, medium-temperature mechanical seal and the use of hard alloy material, wear-resistant seal, can effectively extend the service life of mechanical seals. 4, easy installation and maintenance, without moving the pipe system, as long as you remove the pump seat nut can extract all the rotor components. 5, according to the requirements of the use of flow and lift needs of the pump string, parallel operation. 6, according to the requirements of the pipeline layout using vertical and horizontal pump installation. Pipeline pump main purposes: 1, ISG Vertical Pipeline centrifugal pump for the transport of water and physical and chemical properties similar to other liquids used for water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden sprinkler, fire by Pressure, long-distance transport, HVAC refrigeration cycle, bathroom and other heating and cooling water circulation booster and equipment supporting the use of temperature T2, IRG vertical hot water centrifugal pump is widely used: energy, metallurgy, chemical, textile, paper, High temperature hot water boilers and other pressurized circulating pump and the city heating system circulating pump, IRG-type temperature T3, IHG vertical pipeline chemical pump for the delivery of non-solid particles, corrosive, viscous fluid similar to water, For petroleum, chemical, metallurgical, power, paper, food and pharmaceutical and synthetic fiber and other departments, the use of temperature is 20 ℃ ~ +120 ℃. 4, YG vertical pipe pump for the transportation of petrol, kerosene, diesel and other petroleum products, the medium temperature is -20 ℃ ~ +120 ℃. Pipeline pump causes and troubleshooting: Symptoms may cause troubleshooting methods Pipeline pump not water Import and export of the valve is not open, out of the pipeline blockage, impeller blockage check, remove the blockage Motor running in the wrong direction, the motor phase speed is slow to adjust Motor direction, strong motor wiring pipe pump suction pipe leak tight tighten the sealing surface, excluding the air pump is not filled with liquid, the pump cavity with air to open the pump cover or open the exhaust valve, drain the air inlet and outlet insufficient water supply, suction Too high, the bottom valve leaks shut down inspection, adjustment (grid connection and suction with the use of easy to use this phenomenon). Pipeline resistance is too large, improper pump selection to reduce the pipe bends, re-select the pump pipe pump flow first Press 1. To check the first press 1. To exclude the pipeline, pump impeller impeller blockage, scale deposition, valve opening insufficient Remove obstructions and readjust the valve opening Pipeline pump voltage is low Regulated pipeline pump Impeller wear Replacement impeller Pipeline pump current is too large Pipeline pump exceeds the rated flow Use to regulate the flow rate Small outlet valve Suction is too high to reduce Suction pipe Pump pump bearings Wear replacement bearing pipe pump noise vibration pipe support unstable pipe pipeline pump liquid mixed with gas to enhance suction pressure exhaust pipe pump cavitation reduce the degree of vacuum bearing damage replacement bearing pipe pump motor overload heating operation adjustment press 5 pump motor heating Pipeline pump flow is too large, over-load operation Shut down the outlet valve Pipeline pump rub Check motor bearing damage Replace the bearing Pipeline pump voltage Insufficient pressure Pipeline pump leakage Pipeline pump mechanical seal wear replacement Pipeline pump Pump sand or crack weld repair or replacement Pipe pump seal surface uneven trim pipe pump mounting bolts loose fastening (Editor: Xiaoxia QQ:) Recommended reading: 2017 exhibition information
