What are the spare parts required for a brushless motor-automatic skimmer and how to set up a guaranteed stock?
Brushless motor motor automatic skimmer spare parts and how to set up the protection of inventory is as follows:
I. Common spare parts
1、Electrical
Brushless motor: Brushless motor is the core power components of the skimmer, long time use may appear motor winding short circuit, bearing damage and other faults, resulting in motor can not run normally, so need to have at least 1-2 different specifications of the common brushless motor.
Driver: the driver is used to control the operation of the brushless motor, which may be damaged due to overheating, overcurrent, etc. Generally, 1-2 commonly used drivers should be prepared as spare parts.
Sensors: including photoelectric sensors, Hall sensors and so on, they are used to detect the position of materials, motor speed and other information, easy to be polluted by dust, oil or degradation of performance due to long-term use, each kind of sensor should be prepared 2-3.
Relay and contactor: these components are used to control the circuit on and off, frequent action may lead to contact erosion, need to prepare different specifications of the relay and contactor each 3-5.
Fuses and circuit breakers: they play a protective role in case of overload, short circuit and other faults in the circuit, and may fuse or misoperate due to overload, so prepare 5-10 fuses and circuit breakers of different rated currents.
2、Machinery
Conveyor belt: Conveyor belt is the key part of the material conveyor, it will be worn and torn in long term use, according to the specification of the collector, prepare 1-2 conveyor belts with different length and width.
Receiving rollers: Receiving rollers may be worn, deformed, etc., affecting the effect of receiving materials, prepare 2-3 receiving rollers with different diameters and lengths.
Chain and sprocket: Chain and sprocket will be worn and elongated in the process of transmission, so it is necessary to prepare 2-3 sets of chain and sprocket with different pitch and number of teeth.
Bearings and shafts: bearings and shafts are important parts to support the transmission parts, which are easy to be damaged due to wear and fatigue, etc. According to the requirements of the equipment, 5-10 bearings and shafts of different specifications should be prepared.
Belts and pulleys: belts may slip and break during transmission, and pulleys may wear out and loosen, so prepare 3-5 belts and pulleys of different types.
3、Other
Seals: including seals, gaskets, etc., used to prevent the leakage of lubricants, materials, etc., to prepare a number of different specifications of the seals.
Connecting bolts and nuts: various specifications of connecting bolts and nuts, used to fix mechanical parts and electrical components, prepare different specifications of the bolts and nuts 50-100.
Grease and lubricating oil: used for lubrication and maintenance of mechanical parts, according to the needs of the equipment, prepare the appropriate amount of grease and lubricating oil.
First, to protect the inventory setup method
Historical data analysis: review the past period of time the operating records of the collector, statistics on the frequency of replacement of spare parts and the use of the number, analyze the pattern of failures and trends, as a basis for determining the initial value of the protection of the inventory.
Evaluation of equipment operating conditions: Evaluate the current operating conditions of the reclaimer, taking into account the age of the equipment, the working environment, the operating load and other factors. If the equipment is aging seriously or the working environment is harsh and the operating load is large, the guaranteed stock of spare parts should be increased appropriately.
Supplier Delivery Cycle: Understand the delivery cycle of each spare parts supplier, and increase the guaranteed stock for spare parts with a long delivery cycle to prevent equipment downtime due to lack of stock.
Production plan and demand: Combined with the enterprise's production plan and demand for the use of the skimmer, predict the possible equipment operating time and workload in the coming period of time, accordingly adjust the guaranteed inventory. If there is a large-scale production tasks or production season, should be appropriate to increase the level of guaranteed inventory.
Cost factors: Comprehensively consider the procurement cost, storage cost and out-of-stock cost of spare parts. For spare parts with high procurement cost and large storage cost, try to reduce the guaranteed inventory under the premise of ensuring normal operation of equipment; for key spare parts with high stock-out cost, ensure sufficient guaranteed inventory.
Regular inventory and adjustment: Establish a regular inventory system to regularly check the quantity of spare parts in stock, and adjust the level of guaranteed stock in a timely manner according to the actual use and changes in the above factors to ensure the reasonableness and effectiveness of the guaranteed stock.
