To shorten the downtime for equipment repairs, a certain number of accessories are often stored in the spare parts warehouse, called spare parts.
Spare parts are an important material condition for equipment maintenance. The timely supply of spare parts can not only improve the company's equipment intact rate but also shorten the downtime for equipment repairs. Therefore, each enterprise must do a good job in the supply of spare parts. In addition to the planned and scheduled production of spare parts following the equipment warranty plan, it must also produce and reserve a certain variety and quantity of spare parts. There are many classifications of paper machine spare parts. To facilitate management and supply, they are generally classified according to the following methods.
The following is a list of contents:
·According to the category of parts
·According to the source of parts
·According to the characteristics of parts
·According to the precision of spare parts and the degree of manufacturing complexity
·The difference between equipment spare parts and other materials
Mechanical parts: refers to the special mechanical components that constitute a certain type of equipment, which can generally be manufactured by the enterprise;
Supporting parts: Refers to standardized paper machine spare parts produced by professional manufacturers that are commonly used in various equipment.
Self-prepared parts: refers to the paper machine spare parts designed, surveyed, and manufactured by the enterprise itself, which belong to the category of mechanical parts.
Outsourcing spare parts: refers to the paper machine spare parts that the enterprise purchases on an external order and the general supporting parts are all outsourcing spare parts.
Regular spare parts: Refers to paper machine spare parts that are frequently used, have large losses due to equipment shutdown, and have a low unit price, and need to maintain a certain amount of reserve.
Extraordinary spare parts: Refers to paper machine spare parts with low frequency of use, low downtime loss, and high unit price. According to the preparation method, they can be divided into two types: planned purchase and anytime purchase.
Key parts： Refer to paper machine spare parts with high precision, high manufacturing difficulty, and a key role in the equipment.
General parts: refer to spare parts paper machines for mechanical other than key parts.
To facilitate management and reduce spare parts reserve funds, the following materials are usually not included in the scope of paper machine spare parts. In actual work, attention should be paid to the difference between paper machine spare parts and these materials.
1. The difference between spare parts and low-value consumables
Standard fasteners, connecting rods, handballs, oil cups, oil marks, paper pads, felts, insulating tapes, fuses, low-voltage rubber tubes, etc. that are often used in the equipment maintenance process are not part of the paper machine spare parts. It is stored in an auxiliary material warehouse or tool room as low-value consumables and is used for amortization according to actual needs.
2. The difference between spare parts and materials
To shorten the parts processing cycle, a certain amount of castings, forgings, copper rods, aluminum rods, quenched and tempered steels, etc. must be stocked. These are all materials. They are managed in the blank warehouse, material warehouse, or spare parts stock, and generally do not occupy paper machine spare parts.
3. The difference between spare parts and tools and equipment accessories
Parts on the equipment that are replaced with product specifications and process changes, such as chucks, chucks, indexing heads, grinding wheels, blades, knife bars, rotary tables, flat-nose pliers are not paper machine spare parts and should be used as tools and Equipment accessory management.
Distinguish the paper machine spare parts from other tools will help you better understand the knowledge of the paper machine. Please read it carefully.
