Farm Axial series axial flow pump manufacturer QSZ

Farm axial pump manufacturer QSZ series pump, operating various types of axial flow pump, Francis pumps, submersible pumps, stainless steel pumps, fountain pumps, agricultural pumps, and mobile winding irrigation machinery and equipment, welcome to plant inspection, visit guidance. Introduction and features axial flow near the blade axial flow impeller rotating wheel to force the liquid produced by the liquid in the axial direction of the delivery of the pump, vertical, horizontal, inclined and Tubular several species. China since 1961 has developed a total of 664 sets of large axial flow pump. Its specific speed n are 500,700,850,1000,1250,1400,1600 like; runner diameter of 1.6m, 2.0m, 2.8m, 3.0m, 3.1m, 4.0m and 4.5m. In Jiangsu, Hubei, Hunan, Anhui, Guangdong, Tianjin, Shandong, Shanxi, Shaanxi, Xinjiang and other 16 provinces, municipalities and autonomous regions to build a total of 114 large axial flow pump station with a total installed capacity of 630,000 kW. Axial flow impeller equipped with 2 to 7 blades, rotating in the pipe-shaped pump housing. On the upper part of the pump impeller housing with fixed vanes to eliminate rotational motion of the liquid, making it a axial movement and rotational kinetic energy is converted to pressure energy movement. Axial flow pump is usually a single-stage, two-stage minority made. Large flow range, from 180 to 3.6 million m3 / h; head is generally 20 meters. Generally vertical axial flow impeller is submerged in the water below, there are horizontal or inclined axial pump. Small axial flow impeller mounting location above the water when you need to start with a vacuum pump exhaust water. Axial pump blade fixed and adjustable sub-two structures. Large Axial use conditions (mainly traffic) running often need to make a large change, adjust the blade angle of the pump can be installed in different conditions to keep running at high efficiency area. Leaves small pump installation angle is generally fixed. Axial flow pump is a dynamically than one of the highest number of revolutions, the specific speed of 500 to 1600. Pump flow - head, flow - shaft power curve is steeper in low flow areas, it should be avoided in this unstable run small flow area. Axial pump at zero flow shaft power maximum, so the pump must be open before the start of the discharge line valve to reduce the starting power. Axial flow pump is mainly used for low head, high flow applications, such as irrigation, drainage, drainage docks, locks along the canal water level regulation, or as a large power plant circulating pumps. The water jet propulsion axial pump with a higher lift (made when necessary two-stage) for the ship in shallow water. Note the use of matters 1, test runs, you should check the site links, ensure that all joints without loosening. 2, electrical, instrumentation work; the oil, gas, water pipes each system may not have leakage; pressure, hydraulic pressure is normal. 3, always check whether there are floating near the inlet to prevent clogging intake. 4, the temperature axial flow pump should not exceed 75 degrees of rolling bearings. 5, pay attention to the sound and vibration of the pump, abnormal immediately stop inspection. 6, the temperature of the gearbox oil should be normal.
