Industrial Ice Maker

  Industrial ice machines need to be tested for leaks before running. Leak testing covers several aspects. Let’s get to know the methods of leak testing and how to solve the leaks. 1. Intuitive visual leak detection When R22 leaks, the refrigerant oil will also seep or drip out. Using this feature, you can judge whether there is a leak in the place by visual inspection or by touching it with your hands. When the leakage is small and it is not obvious to touch with your fingers, you can wear white gloves or touch the suspicious place with white paper to find the leakage. When oil stains are found somewhere in the refrigeration system, this may be a leakage point. Intuitive visual leak detection is simple and easy, without cost, but has great defects. Unless the system has a large leak that suddenly breaks and the system leaks liquid and colored media, the visual leak detection cannot be located, because the leakage area is usually very large. It is subtle, and ther...

  Some customers will ask what the state of the cold storage room is during normal operation. Today, I will give you a popular science knowledge about the normal operation of the CBFI cold storage room . 1. There should be no noise in the cylinder, only the normal and regular cold storage sound of the suction valve. 2. The suction temperature of the compressor should be 5-15℃ higher than the evaporation temperature (R22). 3. The condenser cooling water in the cold storage room should be sufficient, the water pressure should be above 0.12mpa, and the water temperature should not be too high. 4. For the new series of products, the reading of the oil pump pressure gauge should be 0.15-0.3mpa higher than the suction pressure 5. There should be no foot heating and frosting on the cylinder wall, and the surface temperature difference should not be greater than 15-20 degrees. For refrigerated or low-temperature systems, frosting of the suction pipe can generally r...

The editor of CBFI, a Chinese ice machine manufacturer , believes that the current domestic and foreign ice making machine have their own characteristics in terms of price, technology, and functions. When companies purchase chiller equipment, they can follow the "four requirements" to help companies purchase compressor equipment. When, choose the one that suits you best. 1. To compare equipment The same PLC is controlled and the same man-machine interface is operated, but the number and methods of control points are very different. There will be qualitative differences in the reliability, safety, stability, accuracy, and sensitivity of the equipment. Of course, the manufacturing cost of the equipment is different. The selling price will also vary. So don't be overly superstitious about PLC, but also in-depth comparison. 2. Pay attention to functions What are the equipment functions you most want, what are the main ones, and which supplier provides the e...

  Some customers reported that the cold storage room 's compressor stops suddenly during operation some time ago. Now let’s analyze the reason and how to deal with it. 1. The cold storage room effect of air-cooled condenser is poor 【Fault Analysis】 ① The fan is not turned on. To ② The fan motor is damaged. ③ The fan is reversed. ④ The ambient temperature is high (above 40℃). ⑤ The condenser fins are blocked by oil and dust and the air does not circulate. 2. The heat dissipation effect of the cold storage room of the water-cooled condenser is poor ① The cooling water valve is not opened or opened too small, and the inlet water pressure is too low ② The water control valve is out of order. ③ The scale on the wall of the condenser tube is thick. [elimination method] Air-cooled: Use a wire brush to remove surface dust. Water-cooled: Check the cooling water volume. Remove limescale. 3. Too much refrigerant is charged in the system [Fault analysis] Excessive refrigerant causes...

  The most common ice factories are edible ice and industrial ice factories. For the selection of an ice plant, many factors need to be considered, such as investment costs, operating costs, maintenance costs, water supply and preference for ice types. Ice manufacturers must design and manufacture ice cubes that can meet the needs of the local market with the existing equipment. Whether it is a new ice factory or an old ice factory, only by controlling lower costs will it be more competitive in the local ice market force. Therefore, the choice of automatic ice-making equipment and the competitive environment in the local ice-making market are factors that investors need to consider and investigate. In addition, investors also need to consider total production costs (including operating costs and the rate of return on invested capital). The high operating costs of ice-making plants can easily lead to increased ice-making costs and lower competitiveness. In the long ru...

  Ice blocks are ice products that have the largest external dimensions and the smallest contact surface with the outside world, and are not easy to melt. Ice blocks are large in size, have a lot of cold storage, melt resistance, low cost, and simple operation. After crushing, the contact surface between the ice cube and the object is enlarged, which can quickly cool the food, slow down the deterioration of the food, and extend the preservation time. The size of the ice blocks can be customized according to the size of the ice bucket. The ice blocks can also be crushed according to different usage requirements, and the crushed ice can be used in all industrial places. Ice blocks are suitable for ice factories in ports and docks, food processing, aquatic product preservation, cooling, long-distance transportation, aquatic products, food preservation, cooling and cooling in special fields, and ice sculpture viewing. Especially suitable for areas with high ambient temper...

  The senior engineer said that there are 13 problems that cause the compressor failure of the ice making machine . Today we will talk about the principles and improvement measures of the compressor failure caused by 3 problems in the crankcase. Firstly,  a large amount of foam is generated in the crankcase Overhaul ideas The lubricating oil in the crankcase foamed and liquid hit was caused by the following two reasons: 1. There is a large amount of ammonia liquid mixed in the lubricating oil. When the pressure drops, the ammonia liquid will evaporate and cause a lot of foam. For this, the ammonia in the crankcase should be evacuated. 2. There is too much lubricating oil in the crankcase, and the big end of the connecting rod stirs the lubricating oil and causes a lot of foam. For this, the excessive lubricating oil in the crankcase should be released to make the oil level reach the specified oil level line. Second, the pressure in the crankcase increases ...
