In the installation of horizontal pipe pump, it should be used in the right way, otherwise it will affect the normal operation of horizontal pipe pump, in addition, the maintenance of horizontal pipe pump is also very important, if there is a failure, in time Maintenance treatment. Inventory of horizontal pipe pump installation and maintenance points (A) of the installation of horizontal pipe pump 1, find the centerline alignment is to find the horizontal pipe horizontal and vertical centerline. Set the vertical and horizontal center lines on the top surface of the foundation first, and then hang the horizontal and vertical flanges on the inlet and outlet flanges (double suction centrifugal pump) and the center of the shaft respectively. Adjust the position of the horizontal pipe pump so that the vertical line coincides with the vertical and horizontal center lines on the basis of the vertical line. Centrifugal pump installation method. 2, find the level of horizontal alignment is to find the vertical horizontal and horizontal horizontal pipeline pump. Generally use the spirit level or hanging line method, single-stage centrifugal pump measured in the pump shaft and the outlet flange. Double suction centrifugal pump in the import and export of horizontal pipe pump flange surface measurement, with the method of adjusting the horn, so that the bubble level of the instrument, or flange to the vertical distance equal to or coincident with the vertical line. Horizontal double suction centrifugal pump can also be selected in the level of the pump casing can be connected into a cross-shaped four points, the standard ruler at these four points, with the level gauge read the readings of each point, if Readings are equal, then the horizontal and vertical horizontal pipe pump horizontal alignment at the same time. Centrifugal pump installation method. 3, elevation is to find horizontal pipe pump is the horizontal elevation of the horizontal axis of the pump. The purpose of the elevation adjustment is to check whether the elevation of the horizontal pipeline pump is in accordance with the designed elevation, and the level gauge and the water level gauge are used for the measurement. The measurement will be a standard ruler at a known level of elevation Hs, the other level ruler in the horizontal pipe shaft. (B) horizontal pipeline pump maintenance 1, all the parts to be installed scrub clean. 2, Install the mechanical seal on the motor shaft, add a little amount of clean turbine oil or 20 # oil on the surface of the mechanical seal with static and static ring. 3, mounted impeller, impeller nut fastening. (C) horizontal pipeline pump fault maintenance 1, the horizontal pipeline pump fault maintenance operation: the import of pipelines must be filled with liquid, prohibited horizontal pipe pump hot water in the cavitation state long-term operation. Regularly check the motor current 値, must not exceed the motor 颔 rated current. Hot water horizontal pipeline pump after long-term operation, due to mechanical wear and tear, so that the unit noise and vibration increases, the parking should be checked, if necessary, replace the vulnerable parts and bearings, unit overhaul period is generally one year. 2, mechanical seal fault maintenance: mechanical seal lubrication should be clean without solid particles. Mechanical seals are strictly prohibited in the case of dry grinding work. Before you start, you should circumnavigate the triumphal hot water horizontal pipe pump (motor) several times to avoid sudden damage of the graphite ring fracture. Seal leakage tolerance of 3 drops / min. Otherwise, check. (Editor: Huang Nengwen QQ :)
