Description

1 TARIFF A cooling system that enables the cooling of submersible pump motors. JACKET STRUCTURE Technical Area The invention involves placing 5 mm around the motor to ensure adequate cooling of submersible pump motors. with a cooling jacket structure that is assembled and enables the direction of flow. It is related. The invention specifically concerns the installation of submersible motors in environments such as caisson wells and pools. in this case or if the well diameter is much wider than the motor diameter, the motor 10 that provides the necessary water flow rate around the engine to adequately cool its surroundings. It relates to the cooling jacket configuration. State of the Art Cooling jackets are designed to prevent industrial equipment from overheating. A type of thermal insulation and cooling system used for external cooling purposes. It is a cooling system. Cooling jackets are usually filled with liquid or gas and remove heat by 15 It helps maintain the equipment's temperature at a specific level. These jackets effectively dissipate heat. It functions as an outer coating designed for dispersion in some way. Submersible pumps are used especially in underwater applications and require their motors to operate continuously. These are devices exposed to high temperatures. Typically used in water supply, irrigation, and sprinklers. clean or 20 systems in groundwater level control and heat pump applications Submersible pumps used for pressurizing slightly contaminated water do not require any external assistance. These are products that operate without being exposed to external factors. In addition to this feature, submersible pumps... For the purpose of extracting groundwater when existing resources are insufficient. They can be used. Submersible pumps have two main parts: the pump housing and the motor housing. It consists of 25 parts. The fan and diffuser parts come together to form the unit. The stages are mounted onto the pump shaft to form the pump housing. The shaft is connected to the motor shaft via a coupling. The suction is generated by the movement received from the motor shaft. Water entering the system from the box is moved to the next stage by the rotating movement of the fans. It is pressurized and then flows into the discharge line. 2 The heat generated in the submersible pump motor is released through the water flow around the motor. This is transferred and this allows the motor to cool down. The submersible pump motor In order for the engine to provide long-term service in accordance with its operating values, the product Regular cooling at the ambient temperature stated in the guide. is required. In this context, minimum water flow rates are necessary for the safe and long-lasting operation of the motor. It is determined to ensure its operation. Minimum water flow rates according to motor types. It must be provided in accordance with the table below. Motor Type Max. Motor Outer Diameter (mm) Minimum Water Flow Rate (m / s) 6” motor ≤ 15 kW 142 0.2 6” motor > 15 kW 142 0.5 8” motor ≤ 52 kW 193.5 0.2 8” motor > 52 kW 193.5 0.5 10” motor 235 0.5 12” engine 286 0.5 Table-1 In current technology, submersible pumps are installed in environments such as caisson wells and pools. In this case, or if the well diameter is much wider than the motor diameter, the motor will be 10. the water flow around it is shown in Table-1 (the values ​​given in the table are international (based on standards and technical manuals of pump manufacturers) shared It has been observed that the values ​​are not in compliance. Similarly, the horizontal position of the submersible pump... In cases where assembly is required, the water flow that occurs around the motor It is observed that it is insufficient. These problems cause the engine to overheat and 15 This leads to a decrease in productivity. As a result of the research conducted on this subject, document number TR 2018 / 11212 was identified. This has been encountered. The relevant document concerns closed-loop cooling systems for submersible pumps. It is related to this. However, current technology allows submersible pumps to be used in environments such as caisson wells and pools. if the installation is done or if the well diameter is much wider than the motor diameter 20 In this situation, it is unable to minimize the water flow around the motor. Therefore, it cannot offer a motor that operates safely and has a long lifespan. 3 In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. The purpose of the invention The invention was created by drawing inspiration from existing situations and addressing the aforementioned drawbacks. 5 It aims to solve the problem. The main purpose of the invention is to cool the submersible pump motor by restricting the water flow area. A cooling system positioned on the submersible pump provides the necessary water flow rate. It's about putting the jacket on display. The other purpose of the invention is to create a cooling system that can be used for different models and brands. to present the jacket. Another purpose of the invention is to enable the submersible pump to operate horizontally thanks to the support legs. If necessary, the submersible pump can be cooled through the cooling jacket and pump housing. The goal is to ensure the pump remains parallel to the ground and is secured to the ground. To fulfill the purposes described above, the invention includes 15 submersible pump motors. If the caisson is to be installed in environments such as wells or pools, or if the well diameter is... if the engine circumference is much wider than the engine diameter, sufficient cooling of the engine perimeter is required. It is a structure that provides, and its characteristic is;  The entire motor housing and at least one part of the pump housing It has a length that will cover the stage, allowing the engine to cool down by 20 minutes. by mounting it on the pump and around the motor to ensure the necessary water flow. a cooling jacket that provides speed by restricting the water flow area It includes. The structural and characteristic features and all the advantages of the invention are given in the figures below. Thanks to the detailed explanation written with references to these figures, it becomes clearer. 25 This will be understood as such, and therefore the evaluation will also take these forms and detailed explanations into account. This should be done taking that into consideration.
