Precautions for use of vertical circulation mixer

LHJ vertical circulation mixer is a new generation of mixing equipment designed and developed for some square or circular tanks with large area and deep pool depth Based on the summary of existing sewage mixing equipment, the structure and performance of the product are innovated, especially on the basis of the propulsion mixer, the horizontal structure is creatively changed into the vertical circulation mechanism so that it can be used in the whole machine Structure, technical performance, mixing efficiency, service area, applicability and other aspects are more significant, with the advantages of long service life, low noise, convenient installation and maintenance, low investment, low operating cost and so on Today, I'd like to introduce the precautions when using the vertical circulation mixer for you: 1 Check whether the products are damaged in the process of transportation, storage and preservation; whether the fasteners are loose or fall off; 2 Check whether there is oil in the oil chamber of the submersible motor and whether the oil quality is good 3 The power supply of the machine is: voltage 380 ± 5%, frequency 50 ± 1% Hz Before each start-up, check whether the power supply device is safe and reliable, whether the voltage and frequency meet the requirements, and whether the grounding device has obvious signs 4 The power lead-in wire shall be equipped with four core YZW rubber sheathed flexible cable It is equipped with 15m YCW heavy rubber sheathed cable If the buyer has special requirements, the cable length can be supplied according to the contract It is not allowed to immerse the cable connector or head in water or get wet by rain 5 This equipment should not be used in inflammable and explosive occasions, nor in highly corrosive medium and flammable liquid 6 Check the insulation of motor and control cabinet before use The insulation resistance value of the motor and control cabinet to the ground shall be greater than 50 megohm, otherwise, it shall be treated as moisture driving; when the insulation resistance value is less than 2 megohm, it must be disassembled for maintenance, at this time, the power cable shall be checked first, then the cable wiring cavity and the motor winding shall be checked Before use, check whether the grounding of the motor is firm and reliable 7 The outgoing cable of the submersible motor must be strictly sealed Before launching each time, check whether the cable is cracked or broken, and whether the cable entrance seal is intact If there is any possible leakage or water leakage, handle it in time It is strictly prohibited to use the cable as a sling to prevent accidents 8 The rotation direction of the equipment in normal operation is counter clockwise from the water inlet direction If there is reverse rotation, just adjust the wiring position of any two cables in the three cables 9 The equipment is equipped with a special control cabinet, which can alarm and display the stator overtemperature, oil leakage, overload, phase loss, short circuit and other faults of the submersible motor, and implement shutdown protection according to the fault conditions If the above faults are displayed on the control cabinet during operation, timely maintenance shall be carried out When purchasing this equipment, please select the control cabinet of our company to effectively protect the equipment 10 The impeller of this equipment has limited particle size through sundries, so plastic bags, metal wires, firewood sticks and other sundries should be avoided to enter into the pool as far as possible to prevent the impeller from winding and failure 11 Always observe whether the equipment operates stably, whether there is mechanical friction sound and other sound, and whether the current value changes If any problem is found, it shall be solved in time.
