Centrifugal pump alignment method, pump alignment method The purpose of horizontal centrifugal pump alignment is to make the center line of the water inlet and outlet of the horizontal centrifugal pump and the pump axis line completely consistent with the corresponding center line planned during the concrete foundation pouring of the horizontal centrifugal pump, so as to be consistent with the motor or diesel engine. Take the horizontal double suction centrifugal pump as an example to align the centrifugal pump: take the vertical and horizontal center lines as the standard, draw a mutually vertical intersection center line in the air above the horizontal centrifugal pump equipment, hang two vertical lines on the two lines, and move the horizontal centrifugal pump so that the center line of its inlet and outlet coincides with the vertical line hanging on the axis. See the following diagram for the alignment method of centrifugal pump During the alignment of the horizontal centrifugal pump, if it is found that the position of the anchor bolt hole is incorrect, or the size of the anchor bolt hole of the horizontal centrifugal pump and the drawing in the attached instruction manual are not aligned, the bolt hole is not aligned with the bolt, or there is no room for movement after alignment, then appropriate measures must be taken, such as increasing the anchor bolt hole of the pump, knocking the bolt, etc., to make the alignment deviation of the horizontal centrifugal pump not exceed the specified value. The alignment method of single-stage single suction centrifugal pump is the same as the above method. It is OK to align the axis line. It should be noted that the outlet center of the single-stage centrifugal pump should meet the design outlet pipeline installation position stainless steel electric ball valve is plugged into feed hole when matters needing attention

1、 Overview of shaft seal free centrifugal pump Shaft seal free centrifugal pump is also known as packing free centrifugal pump. It is usually a vertical canned motor or a horizontal canned motor, which is driven by a wet winding motor without a shielding pad. In this case, the pump and motor share a pressure pump housing, and there is a heat shield between the pump parts and the motor parts. The heat shield can be active or passive. The allowable medium temperature is as high as 420 ℃ 2、 Characteristics of shaft seal free centrifugal pump The bearing is lubricated by discharging medium. In practice, there is no limit to the system pressure, because the total leakage rate is slightly higher than the mark, so it can be used for dangerous media or valuable media. 3、 Special form of shaft seal free centrifugal pump The special form of shaft seal free centrifugal pump is designed according to the application purpose. ·Special impellers for liquid and gas mixtures or suspended solids ·Sealing system specially used for nuclear reactor technology or sealing system with protective gas gasket ·Heating device specially used for quick condensing fluid, such as hot water circulating pump ·Protective cover with abrasion protection vacuum unit of cooling cycle process Liquid ring vacuum pump Liquid ring vacuum pump manufacturer
