Description

Technical Field

[0001] This utility model relates to a heating and lubrication pump unit, and to a lubrication system for mechanical equipment, wind power equipment, construction machinery, etc. that can still operate normally under extremely cold conditions (-20℃~-50℃) to cope with more complex operating environments in the future. Background Technology

[0002] Currently, most lubrication systems, especially those for fan equipment, stop operating below -20°C. In response to the increasing complexity of the market, some high-altitude and cold regions, particularly the Arctic Circle, require fan equipment to operate normally at -40°C and survive at -50°C.

[0003] Under such extremely cold conditions, the viscosity of the grease increases, its fluidity decreases, and the operating load on the lubrication pump motor increases, making it impossible to start and operate normally. To reduce the viscosity of the grease, it can be heated before operation.

[0004] To better address the above issues, this invention incorporates a built-in heating module, along with improvements to the circuitry and mechanics, to better adapt to operating environments in extremely cold regions.

[0005] Currently, commonly used low-temperature resistant lubricating greases on the market exhibit significantly increased viscosity under extremely cold conditions (-20℃ to -50℃), resulting in poor fluidity and low pumpability. Conventional lubrication pumps are simply unable to operate properly for grease dispensing under extremely cold conditions.

[0006] Some heated lubrication pumps on the market have high power and high voltage, posing certain safety hazards, and are particularly troublesome to replace and repair later. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a heating and lubrication pump unit.

[0008] To solve the above problems, the technical solution adopted by this utility model is as follows: To address the challenges of lubricating grease operations in cold and high-altitude regions, a heated lubrication pump unit is proposed, comprising an oil storage tank and a pump body connected vertically. A heating module is installed between the oil storage tank and the pump body; The oil storage tank is equipped with a sealing sleeve containing a pressure plate; The pump body includes a pump base connected to the lower end of the oil storage tank; Several heating modules are distributed above the pump base; The pump core is installed in the pump base.

[0009] As a further improvement to the above technical solution: To prevent the oil inside the tank from getting too cold, a heating rod is installed in the center of the oil storage tank; The oil pressure plate is threaded onto the heating rod.

[0010] The inner cavity of the oil storage tank has a low oil level indicator; To achieve grease distribution, the pump body is hydraulically connected to a main distributor; The main distributor outlet pipe is connected to several sub-distributors; A distributor plunger sensor is installed on the main distributor; The pump body is also hydraulically connected to an overflow valve.

[0011] To ensure uniform heating of the oil and improve heating efficiency, an agitator is installed at the oil outlet at the lower end of the oil storage tank. The quick oil replenishment component is located below the mixer.

[0012] A cover plate is provided at the lower end of the pump base to facilitate the maintenance of the heating module in the future; A motor is mounted on the pump base; A control panel is installed on the pump base.

[0013] To accommodate the electrical control system, a motor cover is installed below the oil storage tank; a bottom cover is attached to the lower end of the motor cover. A control panel electrically connected to the control board is installed in the motor cover; The PLC electrical connection has a control panel.

[0014] To facilitate the support connection, a connecting sleeve is installed at the lower end of the oil storage tank for connecting the pump body.

[0015] To enable temperature monitoring, a temperature sensor is installed between the oil storage tank and the pump body; A liquid level indicator is installed in the oil storage tank; As a monitoring method, the liquid level sensor includes a sensing module that slides on the heating rod and mounts a pressure plate; To achieve a stable connection and provide central support, opposing tower springs fitted onto the heating rod are installed in the oil storage tank. The small end of the opposing tower spring is connected to the spring connecting sleeve; The large ends of the opposing tower springs abut against the top and bottom pressure plates of the oil storage tank, respectively, thereby maintaining pressure and supplying lubricating grease.

[0016] The pump body is connected to an electric motor.

[0017] The outer wall of the oil storage tank has an insulation layer.

[0018] To achieve electric drive, the PLC is electrically connected to the motor, heating rod, heating module, distributor plunger sensor, motor, and distributor plunger sensor; PLC electrically connects to temperature sensor; The heating module uses PTC ceramic; The electric motor is a DC motor, and a diode D1 and a capacitor C1 are connected in parallel between the positive and negative terminals of the motor. The distributor plunger sensor is electrically connected to the liquid level sensor.

[0019] When grease is at low temperature, its viscosity increases and its pumpability deteriorates. This invention adds a heating module to increase the grease temperature, so that the lubrication pump can better adapt to low temperature environments, especially extremely cold environments.

[0020] The heating module of this utility model uses a ceramic semiconductor PTC heating element, which has automatic temperature control characteristics and does not require an additional temperature control circuit.

[0021] This invention uses a PTC heating module, in conjunction with a temperature sensor, to precisely control the start-up time of the lubrication pump. It can also effectively monitor the working status of the heating module, preventing the motor from operating under low temperature overload and thus protecting the motor.

[0022] This invention also optimizes the motor cover and pump base based on existing technology, and adds a heater module, temperature sensor, plug, and silicone plug.

[0023] This invention incorporates a heating module, which is built between the motor cover and the pump base. Its main function is to heat the grease inside the pump base, ensuring the fluidity of the grease around the pump core. This allows the grease to be smoothly pumped out through the pump core and prevents the formation of cavities. Furthermore, it reduces the motor load and extends the service life of the lubrication system.

[0024] The heating module is built between the motor cover and the pump base. The design adopts a pull-out compartment structure, which can adjust the number of heating modules according to the actual needs of customers. It has greater material versatility, is more convenient for production and assembly, and is particularly convenient for later maintenance and replacement. It can be operated by simply removing two fixing bolts and taking off the cover plate.

[0025] The heating modules all use ceramic semiconductor PTC heating elements, which have automatic temperature control characteristics (the power will automatically decrease as the temperature rises), eliminating the need for additional temperature control circuits, and are energy-saving with a long service life.

[0026] To simplify customer control, the preheating time can be set in advance based on the lowest operating temperature (for different greases and different operating temperatures, preheat for 10-20 minutes and directly control the on / off time of the heating power supply).

[0027] Depending on the complexity of the operating environment, a temperature sensor can be installed inside the lubrication pump housing to preheat the pump in extremely cold conditions. The pump will only start when the set temperature is reached, allowing for precise control of the start-up time. This results in more energy-efficient lubrication systems and effectively prevents excessive motor load due to low grease temperature, which could shorten motor lifespan.

[0028] This utility model optimizes the pump seat structure by incorporating a built-in heating module. The design adopts a pull-out chamber structure, which allows for quick adjustment of the number of heating modules according to the customer's actual needs. Furthermore, it is particularly convenient for later maintenance and replacement, requiring only the removal of two fixing bolts and the removal of the cover plate for operation.

[0029] A temperature sensor can be added to the pump base to optimize the control logic of the lubrication pump, turn on the heating module in advance, and start the lubrication system when the grease temperature reaches the start-up temperature of the lubrication pump through the detection feedback of the temperature sensor, thus forming an effective control system.

[0030] This utility model is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use. Attached Figure Description

Detailed Implementation

[0038] A heating module 9 is installed between the oil storage tank 21 and the pump body 22 to heat the lubricating grease. Its ingenuity lies in achieving outlet heating, thereby utilizing the good thermal conductivity of metal to enhance the fluidity of the grease at the pump body. At the same time, it avoids excessive heat loss into the oil tank. Furthermore, the good insulation between the oil tank and the grease is equivalent to adding a layer of insulation to the fluid grease below, thereby preventing heat waste.

[0039] The oil storage tank 21 is equipped with a sealing sleeve and an oil pressure plate 3 for lifting and lowering; this enables downward pressure oil supply.

[0040] The pump body 22 includes a pump base 7 connected to the lower end of the oil storage tank 21 as a mounting support.

[0043] A heating rod 2 is installed at the center of the oil storage tank 21. Utilizing the principle of heat rising and the heat concentration effect at the center of the grease, the upper grease has a certain fluidity. Moreover, heating from the center prevents the heat from dissipating into the air too early or too quickly. At the same time, the rod structure does not affect the free up and down movement of the pressure plate. It can also guide the pressure plate and the spring.

[0044] The oil pressure plate 3 is mounted on the heating rod 2.

[0045] The inner cavity 19 of the oil storage tank 21 has a low oil level indicator 1; In order to achieve reasonable distribution of grease, the pump body 22 is hydraulically connected to the main distributor 25; The outlet pipe of the main distributor 25 is connected to several sub-distributors 26; A distributor plunger sensor 28 is provided on the main distributor 25; it can adopt a conventional structure to realize secondary multi-path distribution of the output grease.

[0050] The outer wall of the tank shell 17 of the oil storage tank 21 has a heat insulation layer.

[0051] PLC24 is electrically connected to motor 23, heating rod 2, heating module 9, distributor plunger sensor 28, motor 10, and distributor plunger sensor 28; PLC24 is electrically connected to temperature sensor 16; Heating module 9 uses PTC ceramic; The motor 23 is a DC motor, and a diode D1 and a capacitor C1 are connected in parallel between the positive and negative terminals of the motor 23. The distributor plunger sensor 28 is electrically connected to the liquid level sensor.

[0052] This invention uses a PTC heating module, and its automatic temperature control feature eliminates the need for an additional temperature control circuit.

[0053] The lubrication pump uses a PTC heating module, along with a temperature sensor, to automatically determine the preheating time of the heater under different working conditions. It can automatically start when the set temperature of the grease is reached.

[0054] The heating module has a simplified structure and is built into the lubrication pump. It can accurately heat local grease, requiring low heating power. It can meet the usage requirements with a 24V power supply, making it more energy-efficient and safer.
