The solvent recovery device is often directly connected to the production line. When the device stops, the tail gas has no place to go, and the production can only stop. The continuity of operation during maintenance, failure or component replacement is one of the most concerned issues of the user. The spare parts and spare parts supply service is organized around this problem: replacement for maintenance, response to faults, and inventory of common parts.
When the maintenance cycle of the device is long, or the maintenance window conflicts with the production plan, the role of the standby machine is most obvious. The standby machine is connected to the system, the original device is out of maintenance, and the production is not affected. For continuous production and rigid users with exhaust emission requirements, the key component-level standby machine and the whole machine-level standby machine can be combined and configured: the whole machine standby machine should be overhauled, and the component standby machine should be common faults.
The spare machine is not valid if it is bought and put away. Regular turning and trial operation are the prerequisites for the spare machine to be available. The state of seals and bearings will change quietly when the machine is left standing for a long time, and problems will occur when it is put into operation.
Accessories are managed in three categories according to consumption characteristics: vulnerable parts are equipped with a batch when the device is delivered, and seals, filter elements and rubber parts that are easy to age belong to this category; Regular replacement parts are stocked on a periodic basis and replenished in advance according to usage records. Key components are stocked according to the ordering cycle. Components with long purchasing cycle such as compressors and board replacement cores are better prepared in advance than temporarily.
The spare parts reserve is based on the use record of the device, not an empirical estimate. Each replacement records the location, time and reason. After one year of accumulation, the spare parts list and inventory can converge to a reasonable level.
| Service Item | Content | Applicable scenarios |
|---|---|---|
| Complete machine | Whole line replacement during overhaul | Continuous production, discharge requirements rigid device |
| spare parts | Critical Component Level Replacement | Key Guarantee of Common Fault Parts |
| Vulnerable parts reserve | deliver a batch at random | High-frequency replacement parts such as seals and filter elements |
| Periodic parts stocking | Replenishment by use record | Parts with stable replacement cycle |
| Long cycle parts | Advance order stock | Compressor and core with long procurement cycle |
| Response Rating | According to the degree of impact | Response conventions for writing service agreements |
The spare parts and accessories solve the problem of "something can be changed", while the response mechanism solves the problem of "how fast to change". Services are classified according to the impact of failures: priority response is given to failures that affect production continuity, and the site is arranged while remote judgment is first; general failures are handled as planned. The response level and contact information are stated in the service agreement to avoid re-negotiation when a failure occurs.
Interface and process conditions match is the premise, processing capacity can be slightly margin. Completely consistent and the most worry-free, when the conditions are limited, according to the "access, can reach the standard" two bottom line selection.
Self-prepared needs to accumulate their own replacement records and channels; The list prepared with the service comes from the usage data of the same model of device, and the inventory and composition are more based, and the replenishment is also followed up by the service provider.
Regular turning, seal replacement, quarterly test run and record parameters. The value of the standby machine is that it is available at any time, and the standby machine that is left undisturbed is the most risky when it is activated.
