Water treatment analysis of air-cooled chiller

1、 Prepare the sewage of air-cooled chiller before entering the pool 1 Start the equipment specified in the instruction in time according to the dispatching instruction 2 Open the gate opener If the power is used to close and open the gate, the handle must be separated from the rotating shaft If the manpower is used, turn off the power and insert the handle into the swing 3 When the gate hoist is opened and closed, it shall be used by guard It can leave the side of the hoist after it is shut down It is not allowed to leave immediately after it is put into operation 4 Open the rotary grid in strict accordance with the use requirements of the rotary grid, keep the machine for ten minutes, check whether the mechanical equipment is abnormal before leaving the machine, and never leave after putting into operation 5 When the water level in the pool reaches the elevation specified in the process, the water pump can be started, and it can be obtained according to the water level of the pool and the on duty dispatching 2 Start and operation of air-cooled chiller 1 Open the inlet and outlet gate of switching well and close other gates according to the dispatching instruction ① Before starting the water pump, the connecting pipe on the stuffing box shall be filled with clean water to lubricate the rubber bearing After the water is discharged from the pump, it can be turned down If there is water dripping out, it is advisable to check the oil level at the bearing position of the pump to ensure that all water and oil circuits are smooth ② before starting the water pump, check whether the connection parts are loose, rotate the coupling by hand to see whether it is flexible and whether there is noise in the pump ③ when the water pump is started, no one is allowed to stand beside the machine After starting, the machine shall be kept for at least five minutes to check the condition of the equipment If there is any abnormal vibration, sound or water outlet, the machine shall be shut down immediately for inspection It is not allowed to leave the pump immediately after putting into operation 2 During the operation of water pump, attention shall be paid to the following items: ① check whether the operation of each instrument is normal and stable, and pay special attention to whether the ammeter exceeds the rated current of motor, if the current is too large or too small, shut down immediately for inspection ② check whether the flow of the water pump is normal, check the water flow of the outlet pipe, estimate the operation time of the water pump according to the water level change of the pool, and timely dispatch ③ check whether the pressure plate of water pump packing is hot and whether the water dripping is normal Each shift shall not be less than eight times ④ pay attention to the noise and vibration of the unit ⑤ Check the temperature rise of bearing motor, stop the machine immediately in case of any abnormality, and inform the on duty dispatcher ⑥ check whether the grid and water inlet are blocked and whether the water level is too low ⑦ the water pump motor is generally allowed to be started six times continuously in cold state, and the interval between two times is at least 15 minutes 3 Stop the machine ① if it meets the process requirements or receives the dispatching instruction, stop the machine immediately and close its gate After stopping the machine, clean the used equipment and clean the surroundings of the equipment ② after shutdown in freezing season, the water in the pump shall be removed to avoid damage to parts ③ The standby pump shall rotate the pump shaft 180 ° by hand every week, pay attention to the oil level mark at the bearing, and refuel in time IV use of maintenance pump, submersible pump and ventilator of air-cooled chiller ① the maintenance pump shall be started according to the regulations of the production department, and shall be clean and intact when not in use ② the submersible pump shall pay attention to the water level of the pool, and shall be started immediately, without leaving the machine, and shall be stopped when the pool is clean ③ the ventilator shall be opened and closed according to the operating experience of the operator V handling of accidents of air-cooled chiller equipment ① in case of any abnormality of the equipment, stop the machine immediately, report to the dispatcher and record in the duty record book When the machine is shut down due to electrical reasons, it shall be reported to the dispatcher immediately for handling, and the electrical equipment shall not be repaired by itself, and shall be recorded in the duty record book ③ in case of motor abnormality, stop the operation immediately, report to the dispatcher, ask for instructions and record in the duty record book ④ if there is any foreign matter blocking the gate and grating, it shall be removed in time If there is an accident signal on the rotating grating, it shall be shut down immediately The report is from Hunan Kaili refrigeration equipment Co., Ltd
