How to proceed with the commissioning of pump? (1-1)
| First, pre-commissioning work 1, check-based hand side should be consistent with the requirements; check anchor bolts, fasteners should be in place; the two-axis precision alignment in line with the requirements. 2, the steering motor, the pump should be the same rotational direction, the electrical insulation should be in accordance with the provisions of. 3, electrical meters and pump pressure gauge, vacuum gauge, etc. should be sensitive, accurate, and the valve should be flexible and reliable. 4, cooling, insulation, washing, filtration, lubrication, fluid sealing and process piping systems should be connected properly, no leakage; pipeline should be washed clean to ensure smooth flow. 5, transmission fluid temperature is higher than 120 ℃ of the centrifugal pump, in order to ensure reliable lubrication of bearings, the bearings should be cooling parts. 6, mechanical seals should be cooling, washing, crystallization of the materials easy to transport, pump should be sealed before the start once again part of the clean crystals, so as not to affect the effect of sealing or sealing surface damage; mechanical seal assembly should be in accordance with the requirements. 7, the use of the pump seal packing, packing should be too tight or too loose; coolant sealing ring to be cooling at the mouth of coolant should be smooth. 8, the lubricating parts, should be added to meet the required lubricant. 9, the entrance must be equipped with pump filter, the filter should be not less than the effective area of cross-sectional area of the entrance of the pump 2 times. 10, torn off and the coupling, first test drive single machine to the motor drive of the trial for more than 2h. | |
