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. No water suction pump causes: 1, suction height is too big. Drain often occurs in mobile devices. When this occurs, it should be allowed to smoke on the height of the pump down to move the position of the pump nameplate. 2, reverse the direction of rotation of the motor. Often it occurs in the pump or moving the newly installed; Drain device, in which case the pressure gauge indicating, but no water discharge. Approach is the three joint motor power lines any exchange a pair of motor rotation direction can be corrected. 3, the bottom valve blockage. Blockage in two ways: First, the bottom valve of the filter is bark, rotten rope, plastic bags and other debris bag to die, the water can not pass; the second is Sump clean-up is not timely, the bottom valve is well in silt, broken The precipitate was buried stone dead. The solution is to clean wells or water-absorbent, warehouse. Meanwhile, in order to prevent the foot valve stuck, grate network should be set out in the barn ditch water between water storage is also provided with a suction grate net wells to prevent water absorption miscellaneous logistics people well. Network Solutions should be kept clean, water storage should be cleared up. 4, suction pipe leak. Suction fittings or install vacuum table tight timber at the leak, resulting in the air suction pipe endless row, causing intense pressure gauge and vacuum gauge swing. Approach is to find out where the leak is processed, such as replacement of water pipe fitting rubber gasket, the lax twine threaded rewound, after wiping a good lead oil tightened. Double suction pump leak reducing effect change: double suction pump impeller outer edge of the suction port of the joints and the pump casing wall there is a rotation of the transfer gap, but the gap is the high and low pressure zones on both sides, the gap is too large, the pump housing The high pressure water will leak through the gap to a low pressure area at the impeller inlet, thereby reducing the pump flow and efficiency. But small, will occur when the inner wall of the pump casing and impeller rotational friction, causing mechanical wear. General use in the construction of two pump leak reducing ways: reducing the transfer gap; 2 increase in the resistance of the leakage path. However, due to manufacturing, installation and axial errors and other issues, at the gap between the gap, it is easy to wear and tear way between the impeller and the pump casing. In order to reduce back flow and prolong the service life of the pump casing and impeller usually insert a metal ring on the mouth of the slit on both sides of the pump housing or impeller, the contact surface of the orifice ring can be made more teeth, to increase the flow reflux resistance, reduce back flow and improve leak reducing effect. This port is used to bearing wear ring wearing parts, so you can always replace the orifice ring without causing the pump housing or impeller scrapped, but can also achieve extended life of the pump casing and impeller purpose, it is also known as Cheng grinding ring.
