Precautions before installation of the pipeline in order to make the pump not due to the installation of pipes and increase excessive force, suction pipe, pressure pipe and valve class to their own support. When the takeover flange is screwed to the pump flanges, it is necessary to confirm that the flange surface is indeed tightly fastened and cannot be excessively tightened by bolts. In addition, considering the expansion of the pipeline, the subsidence of the foundation and the removal of the pump and valve, the Zui is good at using flexible joints near the pump. However, special attention should be paid to, after the pipeline is installed, the flexible joint itself must be rigid joint, so that it does not have elongation under the pressure of the phenomenon. When the pipeline should be buried in the ground, we should consider that the foundation should be adapted to uneven subsidence, freezing and so on. (1) In order to prevent air leakage, the suction pipe should be used as far as possible to use the orchid joint. (2) The layout of the suction pipe road, to try to make from the water suction to the pump has an upward slope (about 1/50) so that the tube does not accumulate air, but when the pipe submerged under the water, from the water absorption to the pump orientation of the slope. (3) The suction tank shall be provided with decontamination equipment (barrier grille).

S Series Open Pump is a large number of general-purpose machinery and equipment, it is widely used in petroleum, chemical, power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, in the national economy occupies an important position. For this reason, the cavitation problem of the open pump in the S series refers to the pressure of the open pump at the entrance of the P1 equal to or less than the saturated vapor pressure PV of the liquid at the same temperature, the liquid vaporization, the bubble under high pressure, rapid condensation or rupture to produce a very high pressure, highly frequent impact, the pump body strong vibration and noise, And significant reduction in efficiency. Then, in the S series, the pump must reduce the cavitation allowance of the pump itself in order to prevent cavitation. There are several specific methods. Reduce the suction height or increase the height of the inversion, reduce the loss, for this reason, we can try to increase the pipe diameter, minimize the length of the pipeline, elbow and accessories, etc., the cavitation will increase during the operation of the medium open pump, so it is necessary to prevent the water from running under large flow for a long time.
