Here are some of the usual cold storage maintenance programs
1. Dismantling compressors. A lot of jokes at the same time say that compressors must be as careful as surgery, and the pistons and screws inside the freezer must be very clear. Axle seals, grinding valves and bearings shall be fine and stable。
2. The technology for the welding of the copper pipes in the freezer is the true skill of its installers. Weld gun in hand, sparkling. Welding is good and can easily lead to leaks in the use of later freezers. Welds are like smooth “fish scales”, which are not only beautiful but also very useful, and only professional welding can withstand high pressure and vacuum tests. It's the only way to make the freezer efficient and durable。
3. Regulations for the operation of pipelines. Every detail of this set of processes relates to the lifetime and effects of the system, so as not to be indisposed。
Fault analysis and screening of the freezer, which requires not only experience, but also brains, is conducted in a situation of failure without the mere exercise of a false handle。
1. See if the compressor is shaking, the evaporation cream is flat, and the pipeline is not “pornified” (this is evidence of a cooling leak)。
2. Whether the hearing equipment has any abnormal impact, friction, or any “sniffing” of the relay。
3. In-depth communication with cold-storage users to understand when the cold-storage was broken and what signs existed before it went bad could save time for trouble diagnosis and improve maintenance deadlines。
Accurate cold-storage operating data, such as pressure, temperature, current, voltage, load, etc., are measured by professional instrumentation, which compares the detected high and low voltage, current, temperature with normal values, and the data speak for themselves. It's easy to spot a malfunction。
