Installation should pay attention: 1, horizontal centrifugal pump installed pipeline should not be added to the weight of the pump, should have its own support, so as to prevent deformation of operational performance and life. 2, pump and motor are integral structure, when installed without alignment, so very easy to install. 3. When you install anchor bolts must be tightened, so as not to affect performance at the start of the vibration of the pump. 4, installation of pumps should be carefully checked before the pump runner whether the impact of a hard object pump operation (such as stone, iron tablets, etc.), so as not to damage the pump impeller and the pump is running. 5, in order to facilitate the maintenance and use of safety in the import and export pipeline pumps, the installation of a valve near the outlet of the pump and a pressure gauge installed to ensure operation within the rated head and flow, ensure the normal operation of the pump, increase The service life of the pump. 6, horizontal centrifugal pumps for suction occasion 80D-12 * 7 pump, should be fitted with a foot valve and inlet pipeline should not have too many corners, and shall not have leaks 80D-12 * 8 pump, drain gas phenomenon. 7, such as the discharge line check valve should be installed outside the gate. 8. After installing toggle shaft, impeller due friction sound or stuck phenomenon, or should check the pump apart cause. 9, installation of horizontal centrifugal pumps into rigid coupling and flexible coupling installation. D46-50X10D46-50X11D46-50X12D85-45X2D85-45X3D85-45X4D85-45X5D85-45X6D85-45X7D85-45X8 shaft sealing device due to the rotation shaft of the pump housing is fixed, at the contact of the shaft and the pump housing must have a certain gap. To avoid a high pressure liquid pump leakage along the gap, or to prevent outside air from entering the pump from the opposite direction, you must set the seal device. Seal means of centrifugal pumps have stuffing and machinery (end) seal. Stuffing is the shaft of the pump casing annulus through the seals made, in which the load soft filler (such as oiled or coated graphite asbestos rope, etc.). Mechanical seal is mounted on the shaft of a ring and the other fixed to the casing of the stationary ring of the composition. Two end faces of the ring by the spring force and close contact with each other for relative rotation, played a seal. Mechanical seals suitable for higher sealing applications, such as transportation acid, alkali, flammable, explosive and toxic liquids. When the centrifugal pump starts, the impeller shaft drive for high-speed rotational movement together, forcing the pre-filling liquid between the blades rotate, the role of the centrifugal force of inertia, the liquid from the outer periphery of the impeller hub for radial movement. Liquid flow through the impeller during movement gained power, static pressure can increase the flow rate increases. When the liquid exits into the centrifugal impeller housing, since housing and decelerate gradually expanding flow channel pump, part of the kinetic energy into static pressure energy, last tangentially flows into the discharge line. So volute casing is to bring together not only by the fluid discharged from the impeller parts, and it is capable of a transfer device. When the liquid thrown from the center toward the outer periphery of the impeller while 80D-12 * 9 centrifugal impeller formed in the center area of ??low pressure in the tank liquid level and under the center of the impeller of the total potential energy difference, resulting liquid is sucked into the center of the impeller. Rely on the continued operation of the impeller, the liquid will be continuously suction and discharge. The mechanical energy of the liquid obtained in the final performance of a centrifugal pump to improve the static pressure energy. Impeller role is the original motivation of the mechanical energy directly to the liquid, to increase the static pressure of the liquid and kinetic energy (mainly to increase static pressure).
