Abstract
Description
Technical Field
[0001] This utility model relates to a heating device for a lubrication pump, belonging to the field of lubrication pump technology. Background Technology
[0002] A lubrication pump is a lubrication device that supplies lubricant to lubrication points. Mechanical equipment requires regular lubrication. Previously, the main method of lubrication was manual lubrication, such as applying grease, performed according to the equipment's operating condition and after a certain maintenance cycle. Lubrication pumps make this maintenance work much simpler. Lubrication pumps are divided into manual lubrication pumps and electric lubrication pumps.
[0003] Existing lubrication pumps suffer from the following problems: First, their structure is too simple, failing to fit the product well and quickly achieve the desired performance. They also have a small heat dissipation area, resulting in low heat dissipation efficiency under similar conditions. Furthermore, they have a low safety factor. When the ambient temperature is too low, the lubricating grease inside the pump becomes increasingly viscous and may even solidify. Excessive viscous grease increases flow resistance, increasing the motor load and potentially affecting its lifespan or burning out the motor, leading to difficulties or damage to the lubrication system. Second, they have a low safety factor, failing to address the safety hazard caused by the heating element continuously heating at high temperatures due to malfunctions. Third, they cannot perform real-time temperature monitoring, making them unsuitable for demanding operating conditions. Therefore, a new heating device for lubrication pumps is urgently needed. Utility Model Content
[0004] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a heating device for a lubrication pump.
[0005] A heating device for a lubrication pump includes a plate-type heat sink that conforms to the inner wall of the lubrication pump. A first region of the plate-type heat sink has a groove, and a second region connected to the first region has a guide groove. A heating tube and a temperature switch connected to the lubrication pump control unit are disposed in the groove. One end of the heating tube is connected to the lubrication pump control unit, and the other end is connected to one end of the temperature switch. The other end of the temperature switch is connected to the lubrication pump control unit.
[0006] Preferably, the groove is further provided with a temperature sensor for detecting the real-time temperature of the heat sink.
[0007] Preferably, the heat sink is made of aluminum.
[0008] Preferably, the guide groove is divided into an edge portion and an inner portion, and a plurality of the inner portions are located at equal intervals inside the edge portion.
[0009] Preferably, the number of inner portions is four.
[0010] Preferably, the inner wall of the groove is further provided with a sealing ring.
[0011] Preferably, a protective shell is also provided on the top of the groove.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model adopts a plate-type heat sink with a guide groove at the other end. The guide groove and the plate-type heat sink can increase the heat dissipation area and improve the heat dissipation efficiency, which can raise the temperature of the grease more quickly. This allows the grease, which has become viscous or even solidified due to low ambient temperature, to reach a state that meets the working requirements. The guide groove can smoothly flow the heated grease into the pump head and pump it out, which can achieve higher thermal conductivity and more precise temperature control, thereby enabling the equipment to operate normally in extreme environments.
[0014] 2. This utility model adopts a temperature switch, which can prevent the heating element temperature from becoming uncontrollable due to malfunction, prevent pump damage or grease deterioration caused by continuous high-temperature heating of the heating tube, and other safety hazards, thereby improving safety.
[0015] 3. This utility model employs a temperature sensor, enabling real-time temperature monitoring. It achieves high-precision detection and control in operating conditions that are sensitive to temperature changes and require high accuracy. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 The principles and features of this utility model are described with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0020] A heating device for a lubrication pump includes a plate-type heat sink 2 that conforms to the inner wall of the lubrication pump 1. A groove 3 is provided in a first region on the plate-type heat sink 2, and a guide groove 4 is provided in a second region connected to the first region. A heating tube 5 and a temperature switch 6 connected to the control unit of the lubrication pump 1 are provided in the groove 3. One end of the heating tube 5 is connected to the control unit of the lubrication pump 1, and the other end is connected to one end of the temperature switch 6. The other end of the temperature switch 6 is connected to the control unit of the lubrication pump 1.
[0021] The groove 3 is also equipped with a temperature sensor 7 for detecting the real-time temperature of the heat sink 2.
[0022] The heat sink 2 is made of aluminum.
[0023] The guide groove 4 is divided into an edge portion 8 and an inner portion 9, and several inner portions 9 are located at equal intervals inside the edge portion 8.
[0024] The number of inner sides 9 is four.
[0025] The inner wall of the groove 3 is also provided with a sealing ring 10.
[0026] The top of the groove 3 is also provided with a protective shell.
[0027] The working principle of this utility model:
[0028] When the set conditions are met, the control unit activates the heating device. When the heating element 5 heats to the maximum temperature limit of the temperature switch (85℃±5℃), the temperature switch 6 activates, and the heating element 5 is de-energized and stops heating. When the temperature of the heating element 5 returns to the reset temperature of the temperature switch 6 (55℃±12℃), the temperature switch 6 resets, and the heating element 5 is energized again to continue heating. Under the same conditions, the heat dissipation efficiency is higher. The design of the guide groove 4 allows for smoother flow of heated grease.
