Brushless motor motor automatic rotor skimmer need what spare parts and how to set up the security stock?
Brushless motor motor automatic rotor reclaimer spare parts mainly involves mechanical, electrical and other aspects, the following are common spare parts and how to set up the protection of inventory:
I. Common spare parts
1、Mechanical
Belt: collector drive commonly used parts, long time use will appear wear and tear, aging, breakage, etc., different specifications of the belt needs to be always on hand.
Chain: used for power transmission, there may be chain elongation, chain link wear and other problems, need to prepare different types of chain and matching chain link.
Bearings: All kinds of bearings are the key to support the rotating parts, such as motor bearings, conveyor roller bearings, etc., which are easy to be damaged due to wear and tear, poor lubrication, etc., so it is necessary to prepare the spare parts according to the type of bearings used in the equipment.
Rotor fixture: in direct contact with the rotor, used to fix and convey the rotor, will be worn out due to frequent use, to prepare a certain number of different specifications or models of rotor fixture.
Receiving tray: the parts carrying the material receiving, may be due to collision, deformation, etc. affect the effect of receiving, need to prepare a spare receiving tray.
2、Electrical
Brushless motor: the core power component of the equipment, there may be winding failure, motor overheating, encoder damage and other problems, need to prepare at least 1-2 sets of the same type of brushless motor as spare parts.
Frequency converter: used to control the speed and operation of the brushless motor, there may be fault alarms, output abnormalities, etc. Prepare spare parts according to the type of frequency converter used in the equipment.
Contactors and relays: commonly used components in the electrical control circuit, prone to contact erosion, sticking and other problems, need to prepare different specifications and types of contactors and relays.
Sensors: such as photoelectric sensors, proximity sensors, etc., used to detect the location of materials, equipment operation status, etc., may be due to dust cover, component aging and other failures, according to the type and number of sensors need to be prepared to prepare a certain amount of spare parts.
Wire and cable: equipment operation, wire and cable may be due to wear and tear, aging, etc., resulting in short-circuit, circuit breakage and other issues, need to prepare different specifications and length of wire and cable.
Second, to protect the inventory setup method
1、Based on historical data
Analyze the frequency of use: Review the replacement records of spare parts over the past period of time (e.g., 1-2 years), count the number of times each spare part is used and the time interval, and determine its average frequency of use.
Calculate guaranteed stock: Determine the quantity of guaranteed stock based on the frequency of use and the procurement cycle. For example, if a certain belt is used 2 times a month on average and the procurement cycle is 1 month, the guaranteed stock can be set to 3-4 items to cope with unexpected situations.
2、Based on the degree of equipment critical
Determine the key components: assess the criticality of each component of the reclaimer, and list the components that are vital to the operation of the equipment, such as brushless motors and frequency converters, as key spare parts.
Set a higher inventory: For key spare parts, the guaranteed inventory should be set relatively high, generally ensuring that it can meet the dosage of 3-5 days of continuous operation of the equipment, in order to avoid a long shutdown of the equipment due to the failure of key components.
3、Based on the supplier's situation
Evaluate the stability of supply: Evaluate the suppliers of spare parts to understand their production capacity, delivery time, reputation and so on. If the supplier's supply is unstable or the delivery period is long, it is necessary to increase the guaranteed inventory.
Establishment of strategic inventory: For spare parts with higher supply risk, consider establishing strategic inventory, i.e., appropriately increase the quantity of inventory to cope with possible supply interruptions.
4、Comprehensively consider the cost
Calculate the inventory cost: analyze the inventory cost of spare parts, including procurement cost, storage cost, capital consumption cost, etc.. For the higher cost spare parts, try to reduce the guaranteed inventory under the premise of ensuring the normal operation of the equipment.
Balance cost and risk: By comprehensively evaluating the loss of equipment downtime and inventory costs, find a balance point and determine a reasonable level of guaranteed inventory to minimize the total cost.
