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 -
How to solve the problem of loud noise cold storage compressor?
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 -
Why is the exhaust temperature of the cold storage compressor too high?
The main reasons for overheating of the compressor exhaust temperature are as follows: high return air temperature, large heating capacity of the motor, high compression ratio, high condensation pressure, and improper refrigerant selection. 1. Return air temperature The return air temperature is ...Read more -
What factors affect the cooling of cold storage?
1. The cooling capacity of the cold storage compressor decreases 2. The evaporation pressure is not suitable 3. Insufficient liquid supply to the evaporator 4. The frost layer on the evaporator is too thick If your cold storage time is long, there may be the following reasons: 5. The evaporator c...Read more -
What faults must be dealt with during refrigeration maintenance?
How to solve the problem of blockage in the refrigeration system is a concern of many users. Blockage in the refrigeration system is mainly caused by oil blockage, ice blockage or dirty blockage in the throttle valve, or dirty blockage in the drying filter. Today I will ...Read more -
How does the condenser work?
A condenser works by passing gas through a long tube (usually coiled into a solenoid), allowing heat to be lost to the surrounding air. Metals such as copper have strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks wit...Read more
