What spare parts are needed for the automatic needle bearing press-in machine for brushless motor motors and how to set up the guarantee stock?
Brushless motor motor automatic needle bearing press-in machine spare parts and how to set up the protection of stock is as follows:
I. Spare parts
1、Mechanical
Bearings: Needle roller bearings themselves and other common bearings that may be used in transmission and other parts, such as deep groove ball bearings, etc., may be damaged due to wear and fatigue and other reasons during long-term operation.
Seals: the equipment's hydraulic system, lubrication system and some parts that need to be sealed, such as cylinders, tubing connections, etc., seals may be aging, deformation leading to leakage.
Belt and Chain: Belt and chain used for power transmission will be stretched, worn, broken teeth and so on due to long time use.
Screws and Nuts: Screws and nuts in the linear motion mechanism of the equipment may suffer from wear and loss of precision.
Pressure head: The pressure head that acts directly on the needle roller bearings is a wearable part, which will be worn and deformed due to frequent pressure action.
2、Electrical
Motor: Brushless motor may have short-circuit winding, broken circuit, bearing damage and other faults, need to have the same type of motor.
Sensors: Pressure sensors, displacement sensors, etc. may be degraded in precision, unstable signals or even damaged due to long-term use and environmental factors.
Relays and contactors: The contacts of relays and contactors in the control circuits are subject to wear and abrasion due to frequent switching.
Circuit boards: The control circuit boards and drive circuit boards of the equipment may fail due to the aging of electronic components, short circuits and other reasons.
3, hydraulic pneumatic category (if any)
Hydraulic pump: the power source of the hydraulic system, there may be pump shaft wear, seal damage, fatigue of internal parts and other issues.
Solenoid valve: used to control the hydraulic or pneumatic circuit of the on-off, direction, etc., the spool may be stuck, leakage and other failures.
Cylinder: pneumatic actuating element, there may be piston rod wear, seal leakage, cylinder wall wear and other problems.
4、Other categories
Lubricant: Used for lubrication of various moving parts of the equipment, which needs to be replenished and replaced regularly.
Cleaning agent: used to clean the surface of the equipment, internal parts and so on.
Fasteners: screws, nuts, bolts, etc., may be loose and lost during the operation of the equipment.
Second, to protect the inventory setup method
1, analyze historical data
Failure records: Review the past maintenance records of the equipment, statistics on the replacement frequency and time interval of each spare part, to determine which parts are high-frequency replacement and which are low-frequency.
Use of time distribution: analyze the use of spare parts time distribution, to determine whether there is a seasonal or cyclical change in demand.
2、Consider procurement factors
Procurement cycle: Understand the procurement cycle of each spare parts, for the procurement cycle of long parts, such as some imported sensors, motors, etc., should be increased appropriately to protect the inventory.
Supplier stability: assess the stability and reliability of the supplier, if the supplier is prone to supply delays, out of stock, etc., need to increase the level of guaranteed inventory.
3, weigh the cost and risk
Inventory costs: Calculate the cost of holding inventory, including the cost of capital employed, warehousing costs, insurance costs, etc., for high-value spare parts, such as circuit boards, hydraulic pumps, etc., to ensure that the supply of the premise, as far as possible, to control the number of guaranteed inventory.
Out-of-stock costs: Estimate the possible losses caused by out-of-stock, such as production losses caused by equipment downtime, the additional cost of emergency purchases, etc. For critical spare parts, such as brushless motors, pressure head, if out-of-stock will seriously affect the production, you should set a higher guaranteed inventory.
4、Regular assessment and adjustment
Changes in demand: With the increase in the service life of the equipment, the adjustment of production tasks, etc., the demand for spare parts may change, and the guaranteed inventory should be adjusted regularly according to the actual situation.
Changes in the market: Pay attention to the supply situation and price fluctuations in the spare parts market, etc. If the market supply of a certain spare part is tight or the price rises, the guaranteed stock can be increased appropriately.
