Hebei Wo large industrial pump main flow single-stage double-suction centrifugal pumps, Francis pumps, wearable slurry pump, power plant desulfurization pumps, mining multistage centrifugal pump, filter feed pumps, pipes direct the pump , stainless steel chemical centrifugal pump, pump mechanical seal, diesel pump units and other products, and contract non-standard pumps and accessories design, production and processing, water treatment engineering design. Reputation first, quality assurance, prompt delivery. Welcome friends to negotiate business. Double suction centrifugal pump impeller inlet outer edge of the pump (suction chamber) there is a gap between the inner edge. If this gap is too large, flowing from the high pressure impeller imported water will drain back to the impeller through the gap, so reducing the amount of water pumps, reducing the efficiency of the pump; but the gap is too small, although able to reduce the amount of leakage, but will caused by mechanical friction. Double suction pump Accordingly, in order to minimize the amount of leakage, double suction pump while the worn easy to repair or replace, usually in the pump cover and impeller are inlaid a metal ring. Because the ring can reduce the amount of leakage, and can withstand the wear and tear, and the pump inlet is located, so called seal ring, also known as Save the drain ring, bearing ring grinding ring or mouth. Double-suction pump is running a long time, there will be the phenomenon of heat, then in order to let everyone can solve the fault, Here I will introduce double-suction pump in cooling mode four types: 1, the rotor of the film This cooling method is cooling pump at the entrance of a pipeline connecting the double-suction with uniform cooling oil dripping away rotor heat. 2, the so-called wet-air cooling double-suction pump, that is, after the inter-stage or two-stage pump compressed air inhaled, absorbed through the comprehensive and muffler combination of phase transfer. 3, water cooling double suction and compression due to transport gas to generate heat pump, the heat must be transmitted from the rotor housing and distribution. 4, the internal cooling of the rotor in order to double suction pump at higher pressure, practice more efficient cooling method, is about a rotor with a circulating oil cooling, respectively, at both ends of the shaft hole, oil-diameter shaft head hit into, the rotor wall and discharged from the other end. For double-suction pump Fourth seed Cooling I believe we understand after, I believe in the future use will bring more help to us, and it will bring greater benefits for us. Technology double suction pump: pump supported at both ends short pitch, the pump runs, vibration noise, can be properly increases the speed to run the pump inlet and outlet adapted to a wider range in the same line, so that pipeline layout is simple and convenient and beautiful. . Same rotor can reverse operation, reducing the risk of water hammer causing damage to the pump. Unique design high temperature, the pump uses an intermediate support, thick body, seal cooling, bearing thin oil lubrication, the pump can run applications up to 200 ℃ occasions, especially for heating network requirements. Pump some changes in the conditions of use of vertical or horizontal installation, seal can be mechanical seal or packing. Pump exterior applications industrial design, clear lines, in line with the modern aesthetic.
