Stock of spare parts

Our company’s approach is to have the suppliers set up large spare parts supermarkets, and we settle the costs based on the actual amount used. Spare parts companies operate with zero inventory, thus incurring no costs.

Low-value and fragile items can be kept as social inventory, while others depend on one’s own financial resources

It’s a good idea for the supplier to set up large spare parts supermarkets and charge based on actual usage, but this approach only works when there is a significant amount of consumption. . .

Standard general-purpose spare parts go without saying, but specialized spare parts such as compressor bearing shells, seals, rotors, etc. need to be considered based on various factors. The bearing shells or pads for key equipment should be kept in stock in quantities corresponding to the number of units; seals can be stocked at one set per several units, and if possible, it is also necessary to have a rotor available as well.

Regarding the stockpiling of spare parts, it is necessary to strictly adhere to the bathtub curve principle of the equipment lifecycle. Spare parts that are prone to failure must be kept in stock, while emergency spare parts should be stocked based on financial considerations. Some standard parts should be stocked in appropriate quantities or obtained as needed; one key principle is to avoid tying up too much capital!

When determining the inventory level in the spare parts warehouse, several factors need to be taken into account: 1. The lead time for obtaining spare parts; for example, the time it takes for seal components of different brands and models to arrive after an order is placed varies； 2. It is necessary to refer to the replacement cycle specified in the OEM manual, or configure it in accordance with the approved principles for preventive maintenance ； 3. Based on the standby status of the equipment and its importance, appropriately stock necessary emergency spare parts ； 4. In some areas, manufacturers of well-known brands may have dedicated service centers and spare parts warehouses; in such cases, it is sufficient to sign a supply agreement in advance and collect the required items when needed. In general, it is very necessary to establish a computer-based monitoring system. Personal suggestion, for reference only.

There are frequent failures that affect production; it is recommended to keep spare parts on hand. If production is not affected and the procurement lead time is short, have the supplier stock them or make the purchases. Ordinary bearings and gaskets are common spare parts.

It can serve as a reference; implementing effective component life prediction for the condition monitoring of pump spare parts can help reduce inventory. Of course, it is also necessary to have spare parts on hand in case of emergencies.

The accuracy of condition monitoring and life prediction is highly error-prone with current technology; essential spare parts must be kept on hand.
