Technical Field

[0001] The utility model belongs to the technical field of coolers, and particularly relates to a cooler for a hydraulic pump station. Background Technique

[0002] A hydraulic pump station is a device where an electric motor drives an oil pump to rotate. The pump sucks oil from the oil pump and then pumps it, converting mechanical energy into the pressure energy of hydraulic oil. When a large amount of heat is generated in the oil inside the hydraulic pump station during long-term operation, it needs to be cooled. Usually, a cooler is installed for cooling treatment. The existing cooler is a device installed on the hydraulic pump station for cooling and temperature reduction of the oil. When the device is in use, it is convenient to clean the inside efficiently and cool it. It improves the convenience and cooling effect of cleaning the cooling pipes when the cooler main body is installed on the hydraulic pump station.

[0003] When the existing cooler is installed on the hydraulic pump station for cooling and heat exchange, the oil of the hydraulic pump station flows into the interior of the housing, and water enters from one end and flows through the interior of the heat exchange pipes to cool the oil inside. Therefore, when the water source flows through the heat exchange pipes for a long time for cooling, dirt is likely to enter the inner surface of the heat exchange pipes and adhere to their surfaces. When a large amount of dirt accumulates inside the heat exchange pipes, it is not convenient to clean, reducing the cooling effect of the heat exchange pipes, thereby affecting the convenience and cooling effect of cleaning the heat exchange pipes when the cooler is installed on the hydraulic pump station. For this reason, the present utility model proposes a cooler for a hydraulic pump station. Content of the Utility Model

[0031] Embodiment 2

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7, the present utility model provides a technical solution: a cooler for a hydraulic pump station, including a cooler main body 100. The cooler main body 100 includes a housing 101. Two fixing brackets 102 are provided on the outer surface of the housing 101. The cooler main body 100 is fixedly installed at one end of the hydraulic pump station through the fixing brackets 102. An outlet 107 and an inlet 105 are respectively provided at both ends of the housing 101. An oil inlet 103 and an oil outlet 104 are respectively fixedly installed at both ends of the upper surface of the housing 101. A cooling pipe 108 is snap-fitted inside the housing 101. Connect the oil inlet 103 to the end of the oil outlet pipe on the hydraulic pump station, and connect the oil outlet 104 to the end of the inlet pipe. Then connect the outlet 107 to the external water inlet pipe, and fixedly install the inlet 105 to the external water outlet pipe. At this time, after oil enters the housing 101, water flows in through the outlet 107 and passes through the inside of the cooling pipe 108, and the oil contacts the surface of the cooling pipe 108 for cooling. After cooling, the hot water is discharged to the outside through the inlet 105 again. A sewage outlet 106 is provided at the middle position of the lower surface of the housing 101. A sealing plug is fixed inside the sewage outlet 106. When oil slag accumulates inside after long-term use, it is discharged through the sewage outlet 106 by opening the sealing plug. The cooler main body 100 is also provided with:

[0033] A drainage and discharge mechanism, and the drainage and discharge mechanism includes a drainage and discharge assembly provided at the bottom end inside the housing 101. A blanking assembly is provided at the end connection of the drainage and discharge assembly at the end of the sewage outlet 106. When the cooler main body 100 needs to regularly clean the oil slag during the cooling process, the drainage and discharge mechanism can drain the oil slag to the end of the sewage outlet 106 and discharge it, making the discharged oil slag cleaner and improving the convenience of slag discharge treatment after the cooler main body 100 is installed on the hydraulic pump station.

[0034] In order to facilitate the discharge of the oil slag generated at the bottom end inside the cooler main body 100 through the drainage and discharge assembly, in this embodiment, preferably, the drainage and discharge assembly includes a bottom plate 1062 welded and fixed to the bottom end inside the housing 101. A drainage chute 1063 is opened at the middle position inside the bottom plate 1062. When the cooler main body 100 is in use and oil slag is generated at the bottom end inside the housing 101, the drainage chute 1063 can drain it to the lowest end and enter the inside of the sewage outlet 106 and fall.

[0035] In order to facilitate the blanking of the oil slag drained through the blanking assembly into the sewage outlet 106 for discharge, in this embodiment, preferably, the blanking assembly includes sewage holes 1061 opened at the end connection of the drainage chute 1063 at the end of the sewage outlet 106, and the two sewage holes 1061 are symmetrically arranged. The oil slag drained from the bottom end of the drainage chute 1063 can enter the sewage outlet 106 through the sewage holes 1061 for discharge.

[0036] Working principle and usage process of the present utility model: For this cooler used in a hydraulic pump station, before use, first reinforce and install the cooler main body 100 at one end of the hydraulic pump station through the fixing frame 102. When the cooler main body 100 is fixedly installed and in use, connect the oil inlet 103 to the end of the outlet pipe on the hydraulic pump station, and connect the oil outlet 104 to the end of the inlet pipe. Then, connect the water outlet 107 to the external water inlet pipe, and fixedly install the water inlet 105 to the external outlet pipe. At this time, after oil enters the interior of the outer housing 101, water flows through the interior of the cooling pipe 108 through the water outlet 107, and the oil contacts the surface of the cooling pipe 108 for cooling. After cooling, the hot water is discharged to the outside again through the water inlet 105. And when oil slag accumulates inside after long-term use, it is discharged through the sewage outlet 106 by opening the sealing plug;

[0037] Then, when the cooler main body 100 needs to discharge oil slag after use, at this time, open the sealing plug, and the oil slag inside is drained to the bottom end of the drainage chute 1063 by the drainage chute 1063 until it enters the sewage hole 1061. Then, it enters the interior of the sewage outlet 106 through the sewage hole 1061 and is discharged to the outside. And when discharging the oil slag, it is convenient for drainage, and the oil slag is discharged more cleanly, improving the convenience of slag discharge treatment after the cooler main body 100 is installed on the hydraulic pump station;

[0038] Finally, when the cooler main body 100 has been used for a long time and the interior of the cooling pipe 108 has flowed through water for a long time and accumulated dirt that needs to be cleaned, the end of the outer housing 101 can be disassembled, the external thread cover 1080 is loosened and disassembled. With the help of tools, clamp the pulling body 1089 to drive the pull rod 1084 to move. When the pull rod 1084 moves, it drives the slider 1082 to slide inside the chute 1085. When the slider 1082 is pulled, it drives the connecting slip ring 1081 to move. When the connecting slip ring 1081 moves, it drives the control block 1087 to slide and control inside the control groove 1086, so that the connecting slip ring 1081 stably drives the scraper 1083 to move and scrape the inner surface of the cooling pipe 108 for cleaning, making it more convenient to clean the dirt accumulated on the inner surface area of the cooling pipe 108, facilitating regular cleaning for effective cooling treatment during long-term use, improving the convenience and cooling effect of cleaning the cooling pipe 108 when the cooler main body 100 is installed on the hydraulic pump station. And when cooling, restore the connecting slip ring 1081 to its original position and fix it in place.
