Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of compressor surface cooling, and in particular relates to a compressor surface cooling stable operation system. Background Art
[0002] In the existing compressor surface cooling stable operation system, the condensate pump is one in operation and one in standby. The condensate pump is a bucket belt type centrifugal surface cooling pump that has been used for more than 30 years. The shaft often breaks. The bucket belt type centrifugal surface cooling pump has poor mechanical properties and needs to replace the sliding bearing under the impeller after a certain period of operation. Otherwise, the centrifugal force of the impeller and the shaft may become larger and larger, causing the impeller and shaft vibration to gradually increase, causing mechanical accidents, causing the surface cooler liquid level to fluctuate, affecting the operation of the compressor, causing the compressor to interlock and stop, causing great losses to the production system, and the failure rate and maintenance costs are particularly high, which poses a great hidden danger to the stable operation of the production system. The bucket belt type centrifugal surface cooling pump is high in height, affecting the static pressure at the pump body inlet. Utility Model Content
[0003] The problem to be solved by the utility model is: how to effectively improve the static pressure at the inlet of the centrifugal pump body.
[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0005] A compressor surface cooling stable operation system comprises a surface cooler and a centrifugal surface cooling pump. The outlet of the centrifugal surface cooling pump is connected to the inlet of the surface cooler through a pipeline, the inlet of the centrifugal surface cooling pump is connected to the surface cooler through a pipeline, and the centrifugal surface cooling pump is a horizontal centrifugal surface cooling pump.
[0006] Furthermore, it also includes a base platform, and the centrifugal surface cooling pump is fixed on the base platform.
[0007] Furthermore, the height of the base platform is 27 cm.
[0008] Furthermore, the inlet pipe of the centrifugal surface cooling pump is a straight pipe.
[0009] Furthermore, the straight pipe length of the centrifugal surface cooling pump inlet pipe is 515 cm.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] (1) The compressor surface cooling stable operation system of the utility model, the centrifugal surface cooling pump is a horizontal centrifugal surface cooling pump. Compared with the barrel belt type centrifugal surface cooling pump in the prior art, the horizontal centrifugal surface cooling pump reduces the height of the pump body and effectively improves the static pressure at the inlet of the centrifugal pump body.
[0012] (2) The height of the base platform is 27 cm. Compared with the height of the base platform of 80 cm used in the prior art, the utility model reduces the installation height of the pump body by reducing the height of the base platform from 80 cm to 27 cm, which can effectively increase the static pressure at the pump body inlet.
[0013] (3) The pump inlet pipeline of the utility model is changed from a curved pipe to a straight pipe, which can effectively reduce the flow resistance of the medium at the pump inlet. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic diagram of the structure of the compressor surface cooling stable operation system of the utility model. DETAILED DESCRIPTION
[0015] The technical solution of the utility model will be clearly described below in conjunction with the accompanying drawings. Obviously, the described embodiments are not all embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of the utility model.
[0016] It should be noted that the terms "center", "up", "down", "horizontal", "left", "right", "front", "back", "lateral", "longitudinal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0017] like Figure 1 As shown, the utility model provides a compressor surface cooling stable operation system, including a surface cooler, a centrifugal surface cooling pump, the outlet of the centrifugal surface cooling pump is connected to the inlet of the surface cooler through a pipeline, and the inlet of the centrifugal surface cooling pump is connected to the surface cooler through a pipeline. The condensate of the surface cooler is recovered by the centrifugal surface cooling pump and refluxed to the surface cooler, and the condensate is continuously circulated in the surface cooler.
[0018] The centrifugal surface cooling pump is fixed on the foundation platform, which is a base made of concrete. The bottom of the centrifugal surface cooling pump is fixed on the foundation platform. The foundation platform can increase the installation strength of the centrifugal surface cooling pump and prevent the centrifugal surface cooling pump from vibrating during operation and causing the pump body to shift.
[0019] The height of the base platform is 27 cm. Compared with the height of the base platform of 80 cm in the prior art, the utility model reduces the installation height of the pump body by reducing the height of the base platform from 80 cm to 27 cm, which can effectively increase the static pressure at the pump body inlet.
[0020] The centrifugal surface cooling pump is a horizontal centrifugal surface cooling pump. Compared with the barrel-belt type centrifugal surface cooling pump used in the prior art, the utility model reduces the height of the pump body by replacing the barrel-belt type centrifugal surface cooling pump with a horizontal centrifugal surface cooling pump, which can effectively increase the static pressure at the pump body inlet.
[0021] The inlet pipe of the horizontal centrifugal surface cooling pump is a straight pipe with a length of 515 cm. Compared with the prior art pump inlet pipe using a 90° elbow with a length of 170 cm, changing the elbow to a straight pipe can effectively reduce the flow resistance of the medium at the pump inlet.
[0022] In the same industry, the failure rate of old equipment is generally reduced by purchasing the same type of barrel belt type centrifugal surface cooling pump for direct replacement. The utility model adopts a horizontal centrifugal surface cooling pump, and at the same time reduces the height of the base platform, and changes the curved pipe to a straight pipe, which reduces the replacement frequency of the pump body, reduces the greater losses caused by the production system, reduces the failure rate and maintenance rate, reduces safety hazards, saves costs and increases economic benefits.
[0023] The outlet of the centrifugal surface cooling pump is also connected to the condensate pipeline of the power plant, so that the condensate is transported to the power plant.
[0024] The above technical features constitute the best implementation example of the present utility model, which has strong adaptability and best implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the needs of different situations.
[0025] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
