In order to avoid the pipe, valve weight and pipe thermal stress generated by the force and torque than the maximum allowable pump import and export of load, the pump suction and discharge pipe to be set pipe rack. Pump nozzle allowable maximum load should be provided by the pump manufacturer. Vertical or vertical pump outlet, in order to reduce the force on the pump nozzle, the nozzle above the pipeline to be provided with pipe racks, the plane position to be as close to the nozzle, pipe can be used to support pipe longitudinal beam, so often the pump Arranged under the pipe gallery. In order to improve pump suction performance, pump suction pipe should be as short as possible, as far as possible less bend (elbow is best to use a large radius of curvature) to reduce pipeline resistance loss. In order to prevent the pump from producing cavitation, the suction pipe of the pump should avoid accumulating the saccular part of the gas as much as possible. When it is unavoidable, the exhaust valve of DN15 or DN20 should be arranged in the bag-shaped part. When the pump suction pipe for the vertical direction, the suction pipe if the configuration of the different diameter pipe, you should configure the eccentric reducer, so as to avoid the formation of air bags. Liquids with a density of less than 650 kg / m³, such as liquefied petroleum gas, liquid ammonia, etc., should be supplied to the suction pipe of the pump in a gradient of 1/10 to 1/100 to return the gas produced by the gasification to the suction tank to avoid Pump cavitation. Single suction pump at the entrance, it is best to configure a period of about 3 times the diameter of the straight pipe imports. For double suction pumps, in order to avoid double-suction horizontal centrifugal pump cavitation, double suction pipe should be arranged symmetrically to ensure that both sides of the flow distribution. The vertical pipe is connected directly through the elbow, but the axis of the pump must be perpendicular to the plane where the elbow is located. At this point, the import piping requirements as short as possible elbow then reducer, and then import the flange. Under other conditions, the pump inlet should be not less than 3 times the diameter of the straight pipe. Discharge valve between drain valve and check valve at pump outlet. Diameter greater than DN50, but also in the check valve bonnet hole to open the net valve installed. The same size pump import and export valves try to use the same elevation. Import and export of non-metallic pump valve on the weight of the pipeline must not be pressure on the pump body, should be set to rack to prevent crushing pump body and the valve when the valve before and after twisting the valve. Steam reciprocating pump exhaust pipe should be less turning in the condensate may accumulate condensing part of the drainage pipe is set to set aside a large amount of discharge muffler should be installed. Inlet pipe should be set in front of the condensate drain valve to prevent water hammer cylinder. Steam reciprocating pump in operation generally have greater vibration, and the pump connected to the pipeline should be well fixed. When the pump outlet center line and the center line of the pipe pillars distance greater than 0.6m, the export pipeline swing check valve should be placed in a horizontal position, this time does not allow the valve cover installed on the net valve. When the pipe rack in the pump and motor above, in order not to affect lifting equipment hoisting, the pipeline should have sufficient height. Pipeline transporting corrosive liquids should not be arranged above the prime mover. Pipeline bottom of the pipeline to the floor of the bottom of the net distance should not be less than 4m ,, to meet the maintenance requirements. When the pipe rack above the pump body, the bottom of the pipe from the ground clearance height should not be less than 2.2m.
