Custom Refrigerant Suction Line Accumulator Manufacturers

How to avoid the risk of refrigerant leakage during the production process of the refrigeration suction line accumulator?

In the refrigeration system, refrigerant leakage is a problem that cannot be ignored. It will not only lead to a decrease in refrigeration efficiency, but may also cause damage to the environment and equipment. Therefore, in the production process of the refrigeration suction line accumulator, effective measures must be taken to avoid the risk of refrigerant leakage.
Strict control of raw materials and parts
The quality of raw materials and parts directly affects the sealing performance of the accumulator, so they must be strictly screened and tested before production.
For the selection of pipes, high-quality seamless steel pipes or copper pipes that meet national standards should be selected to ensure that their materials are uniform, the wall thickness is consistent, and there are no defects such as cracks and sand holes. During the procurement process, suppliers should be required to provide material certificates and test reports, and each batch of pipes should be sampled and re-inspected to ensure the quality of the pipes through non-destructive testing and other means.
Seals are key components to prevent refrigerant leakage, such as O-rings, gaskets, etc. Sealing materials that are resistant to low temperatures, corrosion-resistant, and elastic should be selected, such as fluororubber, polytetrafluoroethylene, etc. When accepting the seal, check its dimensional accuracy, surface finish and hardness and other indicators to ensure that it meets the design requirements. At the same time, pay attention to the storage conditions of the seal to avoid aging and deformation of the seal due to improper storage.
Zhejiang Jinhao Refrigeration Equipment Co. Ltd has a strict quality control system for raw material procurement and has established long-term and stable cooperative relationships with well-known domestic and foreign suppliers to ensure the quality of the purchased raw materials and parts, laying a solid foundation for avoiding the risk of refrigerant leakage.
Optimization and specification of production process
Advanced production processes and standardized operating procedures are the key to ensuring the sealing performance of the reservoir.
In terms of welding technology, appropriate welding methods and welding parameters should be used. For the welding of copper pipes, the commonly used methods are brazing. During welding, the welding temperature and welding time should be controlled to avoid defects such as pores and slag inclusions in the welding joints due to excessively high or low temperatures. Before welding, the welding parts should be strictly cleaned to remove impurities such as oil stains and oxide scale on the surface to ensure the welding quality. After welding, the welding joints should be visually inspected and pressure tested to promptly detect and eliminate potential leakage hazards.
The processing accuracy of parts also has an important impact on the sealing performance of the liquid storage tank. During the processing, the processing must be carried out strictly in accordance with the requirements of the design drawings, and the dimensional tolerance and form and position tolerance must be controlled. For example, the inner diameter and length dimensions of the liquid storage tank cylinder must be accurate to ensure the installation accuracy of the internal parts; the flatness and roughness of the flange surface must meet the requirements to ensure the sealing effect of the seal.
Improvement of quality inspection and monitoring system
Establishing a perfect quality inspection and monitoring system is an important means to timely discover and solve the risk of refrigerant leakage.
During the production process, strict quality inspection must be carried out on each process. For example, after the parts are processed, dimensional inspection and surface quality inspection must be carried out; after welding is completed, welding quality inspection must be carried out; during the assembly process, it is necessary to check whether the installation of each component is correct and in place. Through process inspection, quality problems in the production process can be discovered and corrected in time to prevent unqualified products from flowing into the next process.
Finished product inspection is the last checkpoint to ensure the quality of the liquid storage tank. Comprehensive performance testing of finished products, including pressure testing, leakage testing, etc. Pressure testing can test the strength and sealing performance of the liquid storage tank under the rated working pressure; leakage testing can use professional equipment such as halogen leak detectors to detect whether there are tiny leaks in the liquid storage tank. Only products that pass all test items can be judged as qualified products and allowed to leave the factory.
Zhejiang Jinhao Refrigeration Equipment Co. Ltd has advanced testing equipment and a professional testing team, which can strictly test and monitor each link in the production process to ensure that the product quality meets the relevant standards and customer requirements.
Strengthening of personnel training and management
The skill level and quality awareness of production personnel directly affect the quality of products. Therefore, it is very important to strengthen personnel training and management.
Regularly conduct professional skills training for production personnel, including knowledge of welding technology, processing technology, quality inspection, etc. Through training, improve the operating skills and ability of production personnel to solve practical problems, so that they can master the production process and operation process, and ensure the stability and consistency of the production process.
Strengthen the quality awareness of production personnel, let them realize the seriousness of the risk of refrigerant leakage, and their responsibilities and roles in ensuring product quality. Through quality case analysis, quality assessment and other methods, the quality awareness of production personnel can be improved, so that they can strictly abide by the operating procedures during the production process and do a good job in every link.
Design and structural optimization
Reasonable design and structural optimization can fundamentally reduce the risk of refrigerant leakage.
In the design process of the liquid storage tank, the requirements of sealing performance should be fully considered. For example, the reasonable selection of sealing structure form, such as the use of double sealing structure, can improve the reliability of the seal; optimize the connection method of parts and components to reduce the number of sealing surfaces and leakage points.
Considering the characteristics and working conditions of the refrigerant, the structure of the liquid storage tank is optimized. For example, a drain port is set at the bottom of the liquid storage tank to facilitate the timely discharge of possible impurities and liquids to avoid damage to the seal due to impurity accumulation; an insulation layer is set on the outside of the liquid storage tank to prevent the performance of the seal from deteriorating due to temperature changes.
Zhejiang Jinhao Refrigeration Equipment Co. Ltd can provide solutions according to customer needs. In the design process of the liquid storage tank, various factors will be fully considered, the design and structure will be optimized, and strong technical support will be provided to avoid the risk of refrigerant leakage.
Environment and equipment management
The state of the production environment and equipment also has an important impact on product quality.
Keep the production workshop clean and dry to avoid the impact of dust, moisture and other impurities on product quality. Clean and disinfect the workshop regularly, control the temperature and humidity of the workshop, and provide good environmental conditions for production.
Perform regular maintenance and care on production equipment to ensure the normal operation of the equipment. For example, calibrate and debug welding equipment to ensure the accuracy of welding parameters; perform precision inspection and adjustment on processing equipment to ensure the processing accuracy of parts. Through good management of equipment, the stability and reliability of the production process can be improved, and quality problems caused by equipment failure can be reduced.
