How to manage cold room？
When you have considered starting a cold storage, have you ever thought about how to manage it after it is built? In fact, it is very simple. After the cold storage is built, how should it be managed correctly so that it can work normally and safely. 1. After the cold storage is built, preparatio...Read more -
How to reduce the cost of cold storage construction?
We are all very familiar with cold storage, which is very common in life. For example, fruits, vegetables, seafood, medicines, etc. all need to ensure freshness. Therefore, the utilization rate of cold storage is getting higher and higher. In order to increase customer satisfaction and higher ben...Read more -
Why suction pressure of the cold storage is high?
Reasons for excessive suction pressure of compressor cold storage equipment 1. The exhaust valve or safety cover is not sealed, there is leakage, causing the suction pressure to rise. 2. Improper adjustment of the system expansion valve (throttling) or the temperature sensor is not close, the suc...Read more -
HOW TO INSTALL COLD ROOM ?
Material preparation before installation The cold storage equipment materials should be equipped according to the cold storage engineering design and construction material list. The cold storage panels, doors, refrigeration units, refrigeration evaporators, microcomputer temperature control box...Read more -
Why does the cold storage compressor crankshaft break?
Crankshaft fracture Most of the fractures occur at the transition between the journal and the crank arm. The reasons are as follows: the transition radius is too small; the radius is not processed during heat treatment, resulting in stress concentration at the junction; the radius is processed ir...Read more -
Reasons for low suction pressure of cold storage compressor
Reasons for low suction pressure of compressor cold storage equipment 1. The liquid supply pipe, expansion valve or filter of the refrigeration system is blocked by dirt, or the opening is too small, the float valve fails, the system ammonia liquid circulation is small, the intermediate cooler li...Read more -
Why does the cold storage compressor consume a lot of oil?
The reasons for high oil consumption of refrigeration compressors are as follows: 1. Wear of piston rings, oil rings and cylinder liners. Check the gap between piston rings and oil ring locks, and replace them if the gap is too large. 2. The oil ring is installed upside down or the locks are inst...Read more -
What is the problem of frequent tripping in cold storage?
What is the reason for frequent tripping in cold storage? 1. Overload. When overloaded, you can reduce the power load or stagger the power usage time of high-power equipment. 2. Leakage. Leakage is not easy to check. If there is no special equipment, you can only try one by one to see which equip...Read more -
What’s problem with the cold storage not cooling?
Analysis of the reasons why the cold storage is not cooling: 1. The system has insufficient cooling capacity. There are two main reasons for insufficient cooling capacity and insufficient refrigerant circulation. The first is insufficient refrigerant filling. At this time, only a sufficient amoun...Read more -
What’s solutions to the problem of cold storage compressor not starting?
If the cold storage compressor does not start, it is mostly due to a fault in the motor and electrical control. During maintenance, it is necessary to check not only various electrical control components, but also the power supply and connecting lines. ①Power supply line failure fault analysis: I...Read more -
What are the adjustment methods for cold storage expansion valve?
The cold storage is composed of storage insulation and refrigeration equipment. The operation of the refrigeration equipment will inevitably produce some noise. If the noise is too loud, it means there may be a problem with the system, and the source of the noise needs to be identified and resolv...Read more -
