What are the inspection contents of feeder points

1.

Generally speaking, spot inspection is to record and save the observation quantity of the equipment (the operation condition of the equipment observed by eyes, such as oil leakage and mess, combined with the 5S of on-site management), meter reading quantity (the value displayed by some important existing measuring instruments on site), and measurement quantity (the value temporarily measured on site, such as vibration temperature) as the basic data of equipment operation

spot inspection needs to use spot inspection instrument, and there are many disadvantages in the way of paper recording in the past

2. I think the content of daily inspection should be to check the safety of equipment

3. 1. Under normal circumstances, the advance or retreat of inspection time shall not exceed half an hour. There shall be no supplementary record or advance record
2. A standing tool with inspection contents is required ring inspection
3. See, hear, smell and touch. Prevention and prevention
4. Strengthen the inspection of key contents of inspection equipment
5. Shift records of equipment workshop

4. Each month's base station inspection can timely understand the operation of the equipment, and timely deal with the equipment with potential safety hazards. The specific inspection scope includes: base station main equipment, base station AC / DC power distribution equipment, base station battery, base station air conditioning, base station power environment monitoring equipment, base station transmission equipment, base station antenna feeder system, base station air conditioning, base station power environment monitoring equipment Base station room security facilities. The inspection items include: working voltage, working current, whether there is alarm, operation condition, equipment connection condition, environmental sanitation, and various security risks of the base station. It includes:

1) the main equipment of the base station, checking whether the indicator light of each mole is normal, using OMT software to find out and deal with the alarm in time, whether the connection between each mole, the feeder transmission line ground wire on the top of the cabinet is connected firmly, measuring whether the system voltage of the cabinet is within the normal range, replacing the st net, and cleaning the equipment

2) base station AC / DC power distribution equipment, the base station AC / DC power distribution system provides power for the whole base station, if the AC / DC system fails, the whole base station will be out of service. During routine inspection, it mainly measures three-phase AC voltage introced by power, three-phase phase line current of switching power supply, neutral line current, DC output voltage, DC output current, etc; Whether the wire and fuse are overheated, whether the power supply is turned off or not, whether the power supply is turned off or not, whether the voltage of primary power off and secondary power off, and whether the parameters of the storage battery are correct, etc; Whether the connection of zero line and ground wire is correct, the ground wire is reliable, the ground resistance is less than 5 ohm, the air switch and cable of AC distribution box are well connected, and there is no potential safety hazard.

According to the maintenance experience, 25% of the total number of services returned e to air conditioning failure in the base station, so attention should be paid to the maintenance of air conditioning in the base station. During routine inspection, the working voltage, working current, leakage of refrigerant, cleaning of st net, inspection of condenser, regular cleaning of condenser, unobstructed drainage pipe, no leakage and normal self starting are mainly measured

5) power environment monitoring equipment of base station. The monitoring equipment is responsible for collecting current, voltage, temperature, smoke sensing, water immersion and other information of base station equipment, and timely feedback to the monitoring, so as to achieve early detection and early treatment. During the daily inspection, it is important to check whether the sensors are normal, whether the alarms can be generated artificially, whether the alarms can be uploaded normally, and check the data with the computer room

6) base station transmission equipment, transmission equipment is also one of the key inspection items, daily patrol inspection equipment whether there is alarm, if there is alarm to each computer room to confirm, and timely processing. Clean up the equipment st net, optical cable, transmission line, optical fiber, grounding wire, etc

7) the antenna feeder system of the base station detects whether the antenna feeder is not loose, whether the grounding is good, whether the tag falls off, whether the diversity reception and VSWR are within the normal range, and timely processes the antenna feeder system beyond the range

8) there are no weeds, combustibles, cracks in the floor / wall, doors and windows, keys, anti-theft facilities, ground leakage, collapse, floor drain or air conditioning drainage, tight hole sealing, lighting and fire fighting equipment in the base station room. The ground network facilities are damaged, the cable wiring is disordered, the connector is loose, the power line is overloaded and heated, and the signs and labels are incomplete or fall off

the above measurement data should be carefully recorded and edited into a database, which can be analyzed regularly to detect faults in time, so as to take precautions.

1、 Cleaning: the surface of main engine and subordinate equipment is free of st, mud and oil, and background color appears

Inspection of tightness: 1. Whether the bolts of mill, pinion, recer and motor are loose; 2. Whether the fastening bolts of mill barrel, end cover, feeder and big gear are loose; 3. Check whether the coupling bolts are loose

(3) lubrication: 1. The oil supply time of the refueling pump is normal, whether the oil supply quantity is normal, and whether there is a phenomenon that a certain pipe does not supply oil. 2. The big and small gears are smooth with proper amount of oil (grease), the oil film between the teeth is uniform, and the meshing surface is free of dryness, metal foam and peeling. The oil level of the internal gear of the recer is normal, and the oil quantity should not be too little or too much. If the oil quantity is too little, it will not have a smooth effect, simply speed up the wear speed of the gears and bearings, and even cause problems in a short time; If the oil quantity is too much, the heat dissipation environment in the body will deteriorate, the body temperature will be too high, and it is easy to form the phenomenon of "oil injection" in the heat dissipation breathing hole and oil leakage in the body seal, which will not only affect the cleaning of the equipment, but also form unnecessary waste. The normal oil level should be two-thirds above the middle of the upper and lower marking lines of the oil dipstick. The oil quality and color shall be normal, the appearance shall be transparent, and there shall be no black viscous phenomenon such as carbon deposition. There shall be no iron filings, sand and other debris in the oil

Other aspects of inspection: 1. Whether the feeder has worn through and leaked slurry. 2. Whether the motor and wires have peculiar smell; 3. Whether the sound of the main engine and its subordinate equipment is normal, whether there is gear bump (dry noise), bearing noise, low "buzz" of the motor e to low voltage or single-phase operation; 4. Whether the temperature of motor, wire and bearing is normal, and whether there is mist spray at the heat dissipation breathing hole of recer

7. There are many kinds of ball mills, such as lattice ball mill and overflow ball mill, dry ball mill and wet ball mill. When choosing ball mill, customers should first consider which kind of ball mill is suitable for them. Take a look at what kind of material you want to grind and choose a ball mill suitable for your own type. Compared with overflow ball mill, lattice ball mill has a lower output, but its structure is relatively simple, so its operation is relatively simple. In addition, how much output do you want to achieve? Each model of ball mill has a fixed output. If the output is large, you need to buy a large model. If the output is small, you need to buy a small model. The choice of ball mill also need to see several manufacturers, choose the company with stronger strength, and strive to buy the ball mill with high cost performance. Because many companies in order to save money, in the proction of ball mill in the process of saving money, resulting in the use of cheaper materials, which directly affects the service life of the ball mill.
