Technical Field
[0001] The utility model relates to the technical field of lubrication devices, and more specifically to a double-line automatic lubrication system. Background Art
[0002] During the use of mechanical equipment, reasonable maintenance and care will directly affect the service life of the equipment. According to statistics, more than half of the failures of mechanical equipment are caused by poor lubrication. Among them, centralized lubrication system and manual lubrication are two common lubrication methods.
[0003] Manual lubrication is a process where the operator manually controls the oil gun or lubrication pump to regularly add oil or fill oil to the lubrication points of the equipment. Although this method is simple and direct, it has some obvious disadvantages. First, the accuracy and stability of manual lubrication are difficult to guarantee. The skills and experience of the operator directly affect the lubrication effect, and it is difficult to ensure that each lubrication can reach the best state. Secondly, manual lubrication is inefficient and requires a lot of manual operation, which increases maintenance costs and time. In addition, manual lubrication is often difficult to achieve timed and quantitative lubrication, which can easily cause problems such as over-lubrication or under-lubrication, thus affecting the operation effect and service life of the equipment.

DETAILED DESCRIPTION
[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0024] Dual-line automatic lubrication system, see Figure 1 As shown, it includes: a fuel tank 100, a distribution valve 200 and a switching valve 300;
[0025] The oil tank 100 has an oil outlet a101 and a return port 102. The oil tank 100 is provided with an oil pump 110. The oil pump 110 provides oil supply pressure to push the oil in the oil tank 100 out from the oil outlet a101.
[0026] The switching valve 300 is a two-position four-way valve, and the switching valve 300 includes: a first interface 301, a second interface 302, a third interface 303 and a fourth interface 304;
[0027] The distribution valve 200 is provided with a first oil inlet 201 , a second oil inlet 202 and an oil outlet b203 .
[0028] In this embodiment, two distribution valves 200 are provided. However, in actual application, the number of distribution valves 200 can be increased to 3, 4 or even more. Figure 1 The connection is required in the same way as the first and second distribution valves;
[0029] Increasing the number of distribution valves 200 can deliver oil to more oil supply points.
[0030] The oil outlet a101 of the oil tank 100, the first interface 301, and the second interface 302 are connected to form a first fluid path A, and the first fluid path A is connected to the first oil inlet 201 of the plurality of distribution valves 200;
[0031] The oil outlet a101 of the oil tank 100, the first interface 301, and the third interface 303 are connected to form a second fluid path B, and the second fluid path B is connected to the second oil inlet 202 of the plurality of distribution valves 200;
[0032] The oil outlet a101 of the oil tank 100, the first interface 301, the fourth interface 304 and the return port 102 are connected to form a return path C;
[0033] The switching valve 300 controls the opening and closing of the first fluid path A, the second fluid path B and the return path C;
[0034] Specifically, a valve stem is provided in the switching valve 300. When the valve stem moves to the first position, the oil flows from the oil tank 100 along the first fluid path A, that is, the fluid flows through the oil outlet a101, the first interface 301, the second interface 302, and the first oil inlet 201 of the two distribution valves 200 in sequence;
[0035] When the valve stem moves to the second position, the oil flows from the oil tank 100 along the second fluid path B, that is, the fluid flows through the oil outlet a101, the first interface 301, the third interface 303, and the second oil inlet 202 of the two distribution valves 200 in sequence;
[0036] The oil pump 110 operates intermittently to apply pressure to the first fluid path A and the second fluid path B;
[0037] The oil outlet b203 of the distribution valve 200 is connected to the oil supply point, which can be specifically connected to the oil supply point of the mechanical equipment. The switching valve 300 controls the on-off of the first fluid path A and the second fluid path B to effectively supply oil to the oil supply point of the mechanical equipment at a regular time.
[0038] Furthermore, the switching valve 300 is connected to a controller 400, which controls the operation of the oil pump 110 and the switching valve 300; the controller 400 is connected to a first control signal line 410 and a second control signal line 420, and the controller 400 controls the operation of the oil pump 110 and the switching valve 300 based on input signals of the first control signal line 410 and the second control signal line 420.
[0039] A pressure detection module is provided in the first fluid path A and the second fluid path B, which can be specifically a pressure sensor, and the pressure sensor detects the fluid pressure in the first fluid path A and the second fluid path B; the pressure detection module can be connected to the first control signal line 410 and the second control signal line 420 to transmit signals with the controller 400.
[0040] When the two-way automatic lubrication system is in operation, when the first fluid path A is connected, the oil tank 100 supplies oil to the distribution valve 200 through the first fluid path A; the pressure sensor detects the pressure in the first fluid path A in real time, and when the pressure does not reach the set value, the first fluid path A remains connected to supply oil, and the second fluid path B and the return path C remain closed; when the pressure value reaches the set value, the switching valve 300 operates to connect the third interface 303 with the fourth interface 304, so that the second fluid path B is connected to the return oil path C, and the oil flows back to the oil tank 100;
[0041] When the second fluid path B is connected, the oil tank 100 supplies oil to the distribution valve 200 through the second fluid path B; the pressure sensor detects the pressure in the second fluid path B in real time. When the pressure does not reach the set value, the second fluid path B remains connected to supply oil, and the first fluid path A and the return path C remain closed; when the pressure value reaches the set value, the switching valve 300 operates to connect the second interface 302 with the fourth interface 304, so that the first fluid path A is connected to the return oil path C, and the pressure is relieved and the oil is returned, and the oil flows back to the oil tank 100.
[0042] The utility model alternately injects oil into the first fluid path and the second fluid path through the reversing effect of the switching valve, injects the oil into each distribution valve, and finally delivers it to each lubrication point.
[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
