Commissioning of cooling towers for clean workshops
Before entering into operation, the cooling tower of the clean workshop should check all operating parts, the distribution system should be clean, the shunt pipe and the water head should be properly installed, and all flow control valves should be opened to avoid excessive water pressure; The pool should be clean and free of any debris; the inlet filter should be clean and should be installed in a proper position higher than the sump; all screws should have a proper turning cabinet, especially the brackets of the fan unit and mechanical equipment, check the shaft coupling Check whether the center line of the device is consistent, and re-align the center line to make it within the tolerance range required by the manufacturer; the control or float valve used as the supplementary water of the sump and its related systems must operate freely; for lubrication, confirm whether the deceleration has been in accordance with the specification and The instruction manual fills the correct grade of clean oil to the appropriate liquid level, and its breathing and exhaust port confirms that there is no obstruction; the fan should rotate freely, and check clockwise to see if there is sufficient clearance at the tip of the fan blade; the electrical connection must be very appropriate , to determine that it will be safe under operating conditions.
The motor and the driven device should not have electrodes, noise, vibration and heat during operation. The motor and the driven device should run for at least half an hour for detailed inspection. Do not separate the motor from the transmission device during the test run, and check the fan used. Check the operation of the vibration cut-off switch and release it manually to check whether the fan is cut off; check whether the supply of supplementary water is reliable and effective; confirm that the discharge system can discharge an appropriate amount water. When activating, the valves of all water collection pipes should be fully opened as much as possible, the cold water collection tank must be filled, and the sprinkler head must be cleaned. Clean the filter. Before starting the pump, the outlet valve of the pump must be closed to avoid extreme water flushing in the water tower pipeline; use the pump to establish a full flow state to confirm that the pump does not exceed the design specifications of the water tower and over-deliver; Before the flow is stabilized within 1H, the control valve must be operated in the water inlet pipe of each room to make the water distribution evenly; the exhaust fan of the cooling tower can be started in any order, and the low-speed operation will be switched to high-speed operation after a few minutes of low-speed operation. Use low speed operation. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean workshops.
Water must be added to the cooling tower to replace the water loss caused by evaporation, discharge, splash and overflow. Usually, the loss of water entrained by the exhaust fan is not much, so it can be ignored; when the water is in the cooling tower When evaporating during operation, many dissolved solids remain in non-evaporating form. If these concentration ratios become large enough, scale and deposits will form in the heat exchanger tube bundles and other piping systems. The flow is reduced at higher back pressures, and cooling tower emissions are necessary to reduce solids concentrations.
