Description

TECHNICAL FIELD

[0001] The utility model relates to cold oiler cooling technical field, concretely is a kind of electric pump lubricating oil cold oiler external cooler. BACKGROUND

[0002] Electric pump lubricating oil is used in electric pump to reduce friction, protect machinery and improve the performance of equipment Liquid lubricant, electric pump lubricating oil can form oil film between friction surface, reduce dry friction, reduce wear and tear. In order to control temperature, improve equipment efficiency, protect equipment and prolong equipment life, electric pump lubricating oil needs to be used with cold oiler, and the main function of cold oiler is to reduce the temperature of lubricating oil. In the normal operation process of steam turbine generator unit, heat is generated due to bearing friction, which causes the temperature of lubricating oil to rise. If the oil temperature is too high, it may cause accidents such as bearing softening, deformation or burning. In order to ensure the normal operation of the bearing, the temperature of the lubricating oil must be maintained within a certain range.

[0003] In the traditional power system, the cold oiler is a key supporting equipment of the steam turbine, mainly used for cooling the lubricating oil of the steam turbine. The lubricating oil cooler usually adopts high-efficiency tubular structure. The lubricating oil cooler cools the lubricating oil by circulating water, can accurately control the outlet oil temperature, and keeps it within the optimal working temperature range, so as to improve the viscosity, viscosity and density of the lubricating oil, reduce wear and tear, and improve the safety of equipment operation, but during the peak summer period, due to high temperature of circulating water and poor water quality, the heat exchange effect of the cold oiler is poor, the oil temperature is high, which seriously affects the safety of the equipment. This way, not only can't guarantee the cooling effect of the cold oiler and the safety of the equipment, but also reduces the service life of the lubricating oil. Therefore, an electric pump lubricating oil cold oiler external cooler is proposed. UTILITY MODEL CONTENTS

[0004] (I) Technical problem solved

[0005] In view of the shortcomings of the prior art, the utility model provides an electric pump lubricating oil cold oiler external cooler to solve the technical problem that the above-mentioned cannot guarantee the cooling effect of the cold oiler and the safety of the equipment, and also reduces the service life of the lubricating oil.

[0006] (II) Technical scheme

[0007] To achieve the above purpose, the utility model provides the following technical scheme: an electric pump lubricating oil cold oiler external cooler, comprising:

[0008] A cold oiler shell and a cooling pipe arranged above the cold oiler shell, and a plurality of drainage holes are uniformly arranged on the lower surface of the cooling pipe.

[0009] A side connecting plate is provided at the end of the cooling pipe and is connected to both sides of the oil cooler housing. Both ends of the cooling pipe are connected to liquid guide pipes, and the ends of the liquid guide pipes extend outward through the side connecting plate. A valve is provided at the connection between the cooling pipe and the liquid guide pipe.

[0010] The water receiving tank is located directly below the oil cooler housing and has a square design with a water storage groove on its upper surface. By connecting the liquid guide pipe to the external pump outlet, the pump delivers cooling water along the guide pipe to the interior of the cooling pipe. The water flow is regulated by a valve, and the cooling water descends through the drain hole to the surface of the oil cooler housing for cooling. The cooled water then falls along the surface of the oil cooler housing into the water storage groove of the receiving tank for collection. This design not only enhances the cooling effect of the oil cooler and allows for easy adjustment of the external cooler's water volume, but also offers low manufacturing costs and wide applicability to external cooling of oil coolers in industrial applications. This solves problems such as poor cooling effect and high oil temperature, improves equipment safety, and extends the service life of lubricating oil. Furthermore, the length and diameter of the cooling pipe can be adjusted according to different sizes and models of oil cooler housings, thus improving the applicability of the device.

[0011] Preferably, the upper surface of the water receiving tank is equipped with guide plates at both the front and rear ends, and the guide plates are inclined. The guide plates can increase the collection range of cooling water in the water receiving tank, preventing some cooling water from falling into the oil cooler housing and splashing outwards, thus avoiding the phenomenon of not being able to collect the water and wasting cooling water.

[0012] Preferably, hydraulic rods are provided on both sides of the guide plate, and the telescopic ends of the hydraulic rods are connected to the outer side of the guide plate. The hydraulic rods can drive the guide plate to move outwards towards the upper surface of the water receiving tank, thereby further expanding the collection range of cooling water in the water receiving tank.

[0013] Preferably, an annular seat is added to the outer side of the hydraulic rod, and a first drive motor is arranged on the outer side of the annular seat. The rotating end of the first drive motor is connected to the surface of the hydraulic rod through the annular seat. The first drive motor drives the hydraulic rod to rotate on the annular seat, causing the guide plate to rotate in the same direction as the hydraulic rod. By adjusting the tilt angle of the guide plate, the tilt angle and position of the guide plate can be adjusted, thereby ensuring the effective collection of cooling water.

[0014] Preferably, a side connecting seat is installed on the lower surface of the annular seat, and a second drive motor is coaxially connected to the outer side of the side connecting seat. The side connecting seat is rotatably connected to the outer side of the water receiving tank, and the second drive motor is connected to the outer side of the water receiving tank. The second drive motor can drive the side connecting seat to rotate on the water receiving tank, and the annular seat rotates in the same direction as the side connecting seat, so that the guide plate can rotate to the lower surface of the water receiving tank, thereby facilitating the storage operation of the water receiving tank and reducing the contact between dust and the guide plate.

[0015] Preferably, the outer side of the water receiving tank is uniformly equipped with supporting side columns, and the supporting side columns are designed in an L-shape. The supporting side columns provide stable support for the water receiving tank, while the L-shape of the supporting side columns can avoid affecting the side connecting seat during rotation.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an external cooler for an electric pump lubricating oil cooler, which has the following advantages:

[0018] This external cooler for electric pump lubricating oil coolers connects a liquid guide pipe to the pump's outlet. The pump then delivers cooling water along the guide pipe to the cooling pipe's interior. A valve regulates the water flow, and the water drains through a drain hole to the surface of the cooler's housing for further cooling. The cooled water then flows down the housing into a water storage tank for collection. This design not only enhances the cooling effect but also allows for easy adjustment of the water flow. It is cost-effective and widely applicable in industrial applications, solving problems such as poor cooling performance and high oil temperature. It also improves equipment safety and extends lubricating oil lifespan. Furthermore, the length and diameter of the cooling pipe can be adjusted to accommodate different cooler housing sizes, enhancing the device's versatility. Attached Figure Description

The water volume is regulated by a valve, and the cooling water descends through the drain hole 3 to the surface of the oil cooler housing 1 for cooling. The cooled water then falls along the surface of the oil cooler housing 1 into the water storage groove of the water receiving tank 6 for collection. The first drive motor 10 drives the hydraulic rod 8 to rotate on the annular seat 9, causing the guide plate 7 to rotate in the same direction as the hydraulic rod 8. By adjusting the tilt angle of the guide plate 7, the hydraulic rod 8 can drive the guide plate 7 to move to the outer side of the upper surface of the water receiving tank 6.
