Test run and commissioning of clean workshop equipment
Before the test run of the supporting water pump in the clean pharmaceutical cleanroom, check whether the components of the water pump and the auxiliary system are fully installed. The bolt connection parts of the water pump should not be loosened. The impeller should be light, flexible and normal to move the impeller by hand, and there should be no abnormal phenomena such as jamming; The valve opening and closing status of the auxiliary pipeline system should meet the design requirements after inspection and adjustment. Before operation, the inlet valve should be fully opened and the outlet valve should be fully closed. After the pump is started, the outlet valve should be opened again. The clamp-type ammeter measures the starting current of the motor, and then measures the running current of the motor after the water pump is running normally to ensure that the running power or current of the motor does not exceed the rated range; after continuous operation for 2 hours, when the rolling bearing is running, the maximum temperature of the bearing should be less than 75 ℃ , If a sliding bearing is used, the maximum temperature of the bearing should be less than 70 ℃; after the pump is checked to be normal, it can be continuously operated for many 2H. If no problem is found during operation, the test run of the pump is qualified, and the test run report is filled in The content is the same as that of the fan; after the trial operation, the inlet and outlet valves of the pump and the valves of the auxiliary piping system should be closed. In the case of non-continuous operation, in order to prevent corrosion and freeze cracking, the water accumulated in the pump should be drained.
The main reasons that cause the outlet of the pump to display pressure, but the water pipe does not flow is: the resistance of the outlet pipe is too large or the pipe is blocked; the impeller of the pump is blocked; the rotation direction of the motor is reversed; the number of revolutions of the pump is not enough. The main reasons for the abnormal sound of the pump and the failure of the pump to fill the water are: the water absorption height is too high; the temperature of the water pumped by the pump is too high; there is air infiltration at the water absorption place. Reasons for the excessive power consumption of the pump: the packing gland is too tight, and the stuffing box is heated; the pipeline resistance is smaller than the design, and the pump flow is too large; the impeller and the sealing ring are worn. The main reasons for bearing heating are: the water pump bearing has no lubricating oil or too much lubricating oil; the shafts of the water pump and the motor are not concentric. The main reasons for the vibration of the water pump are: the shafts of the water pump and the motor are not concentric; the foot bolts are loose. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and purification workshops.
Before the trial operation of the cooling tower, the inclusions and dirt in the tower should be cleaned to prevent the blockage of the cooling water pipe or condenser; the cooling tower and the cooling water pipeline system should be flushed with water, and the pipeline system should be free of water seepage. Check the automatic water supply valve Whether the action state is flexible and accurate, the water level of the make-up water and overflow water in the cooling tower should be checked; when the cooling tower is in trial operation, the operation state of the fan and the working state of the cooling water circulation system should be checked, and the running situation and related data should be recorded. , If there is no abnormal phenomenon, the continuous operation time should not be less than 2H; measure the motor starting current and running current of the fan, and make the running current within the rated current range; check whether the water spray and water absorption are balanced, and the water supply The operating conditions such as the water level of the water collection tank and the water level of the water collection tank should be in a good state that the cooling water does not run and leak; if the cooling tower is not used for a long time after the trial operation, in order to prevent the equipment from freezing, all the water in the circulation pipeline and water collection tank should be released.
