[0001] The invention relates to the technical field of lubricating oil purification equipment, and in particular to a constant temperature purification system and equipment for reducer lubricating oil. Background Art

[0002] During the operation of the reducer, lubricating oil plays an important role in lubrication, cooling and protection. Each lubricating oil can only protect the equipment well if it maintains the best viscosity-temperature characteristics suitable for the equipment at a certain temperature. As the operation time of the reducer increases, the cleanliness of the lubricating oil will also be affected. It may contain impurities such as particulate matter and moisture. These impurities will affect the performance of the lubricating oil, increase the wear of the reducer gears, increase the heat generation, and thus affect the normal operation of the reducer.

[0003] In addition, the temperature of the lubricating oil also needs to be kept within an appropriate range. Excessive temperature will have an adverse effect on the performance and life of the reducer. Traditional reducer lubricating oil treatment systems often cannot effectively achieve lubricating oil purification and constant temperature control at the same time, resulting in a decrease in lubricating oil quality and an increase in the failure rate of the reducer.

[0004] Therefore, in order to improve the operating stability and reliability of the reducer and extend its service life, a system and equipment that can simultaneously achieve constant temperature purification of the lubricating oil is needed to ensure that the cleanliness and temperature of the lubricating oil are always maintained within an appropriate range.

[0026] Example 1

[0027] like Figure 1-Figure 4 As shown, the present invention provides a constant temperature purification system for reducer lubricating oil, including an oil pipeline, a purification unit, a cooling unit and a control unit. An oil pump 1 is installed on the oil pipeline, and the cooling unit is arranged downstream of the purification unit. Solenoid valves 9 are installed at the inlet and outlet ends of the oil pipeline and controlled by the control unit. The control unit includes a touch screen 23 and a controller. The touch screen 23, the oil pump 1, the solenoid valve 9, the purification unit and the cooling unit are all electrically connected to the controller. The control unit accurately controls the oil pump 1, the solenoid valve 9, the purification unit and the cooling unit to realize the automatic operation of the entire system, thereby improving the reliability and stability of the system.

[0028] The purification unit includes a filter 4 and a differential pressure sensor 5 for detecting the differential pressure on both sides of the filter 4. The filter 4 is installed on the oil pipeline. Filter elements of different precisions can be configured according to the impurity situation of the oil. In this embodiment, two filters 4 are provided, including a first filter 4 and a second filter 4. The first filter 4 and the second filter 4 are connected in parallel to each other. The design of two filters 4 connected in parallel is adopted. When one filter 4 needs maintenance or replacement, the other filter 4 can continue to work, thereby ensuring the continuous operation of the system and improving the reliability of the system. The differential pressure sensor 5 is arranged to detect the differential pressure on both sides of the filter 4 in real time, and timely reflect the blockage condition of the filter 4, which is convenient for maintenance and replacement, and ensures the stability of the filtering effect; corresponding to the blockage condition of the filter 4: the system is also provided with an overpressure bypass pipeline 6, and the two ends of the overpressure bypass pipeline 6 are respectively connected to the oil pipelines on both sides of the filter 4, and a two-position normally closed solenoid valve 7 and a switch valve 8 are installed on the overpressure bypass pipeline 6 in sequence, and the two-position normally closed solenoid valve 7 is electrically connected to the controller. If one of the filters 4 is blocked, the controller will open the overpressure bypass pipeline 6 by controlling the two-position normally closed solenoid valve 7 to protect the system from overload, and an alarm will be issued to prompt the replacement of the filter element, and switch to the other filter 4 for operation.

[0029] The cooling unit includes an air-cooled radiator 10 and a temperature sensor 11, both of which are installed on the oil pipeline.

The heat dissipation fan 101 is driven to rotate by a motor 103. The heat dissipation fin 102 is connected to the oil pipeline. The heat dissipation fan 101 is arranged on one side of the heat dissipation fin. The combination of the heat dissipation fin 102 and the heat dissipation fan 101 can quickly and effectively dissipate the heat in the lubricating oil, improve the cooling efficiency, and ensure the temperature stability of the lubricating oil. The heat dissipation fin 102 adopts an aluminum alloy heat dissipation plate. The temperature sensor 11 at the front end of the radiator feeds back the oil temperature signal to the control unit to control the start and stop of the heat dissipation fan 101. A PT100 temperature probe is installed at the outlet end of the radiator. When the temperature exceeds 100 degrees, an alarm is triggered and the heat dissipation fan 101 is automatically started. When the temperature drops to 85 degrees, a signal is fed back to the controller, and the controller controls the heat dissipation fan 101 to stop. The cooling temperature of the lubricating oil can be set on the touch screen.

[0030] Sampling pipelines 2 are provided on both sides of the filter 4 in front and behind the oil pipeline. A sampling valve 3 is installed on each sampling pipeline 2, which is convenient for sampling and testing the lubricating oil at any time, timely understanding the quality status of the lubricating oil, and providing a basis for the operation and maintenance of the system.

[0031] The system can also be optionally equipped with a particle and moisture detection unit 14, which includes a particle detection sensor and a moisture detection sensor. The particle detection sensor and the moisture detection sensor are arranged at the outlet end of the oil pipeline, and the data corresponding to the particle and moisture detection results are displayed on the touch screen 23.

[0032] A first pressure sensor 12 is provided at the outlet end of the oil pump 1 on the oil pipeline, which is used to detect the outlet oil pressure of the oil pump 1 and determine whether the oil pump 1 is operating normally; a second pressure sensor 13 is installed at the outlet end of the air-cooled radiator 10 on the oil pipeline, which is used to detect the pressure drop at the outlet of the air-cooled radiator 10.

[0033] The technical scheme also provides a constant temperature purification device for reducer lubricating oil. By integrating the constant temperature purification system of the reducer lubricating oil into the device, the entire constant temperature purification device adopts a mobile box 15 design, which is convenient for moving the device to the required position for use, thereby improving the flexibility and applicability of the device. Specifically: the device includes a mobile box 15, a universal wheel 16 is provided at the bottom of the box 15, a push-pull handle 17 is provided at the front end of the box 15, and a lifting ring 18 is installed at each corner of the top of the box 15.

The oil pump 1, the filter 4 and the radiator are all installed inside the box 15, and the oil pipeline is arranged in the box 15. The box 15 is provided with openings corresponding to the oil inlet port and the oil outlet port of the oil pipeline. Ventilation holes are provided on both sides of the box 15 corresponding to the radiator, and a dustproof net 21 is installed at the vent to achieve rapid heat dissipation inside the box 15.

[0036] A power plug 24 is provided on the side of the box body 15, which is used to connect a power source to supply power to the entire device when in use.

[0037] Working principle:

[0038] The lubricating oil of the reducer is pumped out by the oil pump 1, and first enters the purification unit for filtering the oil. When the differential pressure sensor 5 detects that one of the filters 4 is blocked, the controller will control the two-position normally closed solenoid valve 7 to open the overpressure bypass line 6 to protect the system from overload, and alarm to prompt the replacement of the filter element, and switch to the other filter 4 for operation. During filtering, the oil on the front and rear sides of the purification unit can be sampled by opening the sampling valve 3 of the sampling line 2, and the filtering condition of the oil can be compared. The filtered oil enters the cooling unit for cooling. The controller controls the cooling fan with variable frequency based on the data fed back by the temperature sensors 11 on the front and rear sides of the air-cooled radiator, and the cooled oil is transported back to the reducer.
