Description

Technical Field

[0001] The utility model belongs to the technical field of oil product online monitoring and filtering, in particular to a system for oil product online monitoring linkage control filter. Background Art

[0002] At present, many factories have gradually changed their lubrication management methods. Traditional lubrication management mainly relies on manual inspections and regular sampling laboratory testing. It is too dependent on manpower and has intervals in regular testing, which cannot detect lubrication problems in time and is no longer suitable for the needs of today's social development. In recent years, popular digital management and online oil monitoring methods have been well received by the industry and have achieved remarkable results.

[0003] In the prior art, many factories are equipped with filters that require manual control to start and stop. Due to blind spots and misunderstandings in the judgment of oil status, when the oil status is poor and the filter is not turned on in time, it is easy to cause the oil to age and fail quickly. When the filter is turned on for a long time and the oil status is good, it will cause a waste of resources. In the current context of intelligent manufacturing, traditional lubrication management and filter applications are still offline, which is not conducive to the digital transformation of enterprises. The existing technical solutions have the following disadvantages: (1) Laboratory testing and online monitoring in lubrication management can only detect problems, but cannot automatically solve them. They also rely on on-site staff to handle them, which has poor timeliness. (2) Traditional management methods have high labor costs and many uncontrollable factors. Therefore, in response to the above problems, it is of great practical significance to provide a system for online monitoring and linkage control of oil filters. Utility Model Content

[0008] The filter is provided with a second oil inlet pipe and a second oil outlet pipe on the side thereof, and a pump connected to a second controller and a filter device with an oil pressure sensor are sequentially connected in series between the second oil inlet pipe and the second oil outlet pipe;

[0009] The first oil outlet pipe is divided into two branches and each branch is controlled by a corresponding single solenoid valve, one of which is connected to the starting end of the second oil inlet pipe, and the other solenoid valve is connected to the auxiliary oil outlet pipe and the main oil outlet pipe; the second oil outlet pipe is connected to the main oil outlet pipe.

[0010] Furthermore, the two solenoid valves are connected to the first controller.

[0011] Furthermore, the first controller and the second controller are both PLC controllers.

Even if there is a leak in the internal oil circuit, it will not affect the circuit, thereby ensuring the safety of the entire device; in this specific embodiment, the particle size detection module 102 adopts the HYDAC CS1000 model, the oil quality detection module 103 adopts the Tan Delta OQSxG2-1-AA-02-5 model, the moisture detection module 104 adopts the VAISALA MMT162 model, and the flow monitoring module 105 adopts the OMEGA FMG 70B model; this specific embodiment only selects the component model of one embodiment for illustration and description. Of course, component models with the same functions and the same effects, which produce the same effects, also belong to the protection scope of this technical solution;

[0027] The flow regulating valve 101 is used to control the oil flow rate in the integrated monitoring box 1, so as to reduce the flow rate to the ideal flow rate range required for detection;

[0028] The particle size detection module 102 is used to detect the particle size of the oil in real time. In the hydraulic and circulation systems, the particle size is very important.

First, the AC power is converted into 12-24V DC power through a power conversion module (not shown in the figure) in the integrated monitoring box to power various devices and sensors built into the monitoring box, and the other direct AC power is used to power the pump in the filter; after the power conversion module converts the power, it is connected to the first controller 106, i.e., the PLC controller module. The PLC controller module is connected to the particle size detection module 102, the oil quality detection module 103, the moisture detection module 104, and the flow detection module 105 through a four-core cable to play the role of power supply and data transmission; the first controller 106 is connected to the industrial control touch screen through a network cable;

[0039] In this specific embodiment, the filter device inside the filter 2 adopts the EPT600508 type, the corresponding Youya sensor adopts the AE SENSOR AE-T type, and the pump adopts the NOP 2MY400-203HBMVB (2300); this specific embodiment only selects the component model of one embodiment for demonstration and explanation, and of course, the component models with the same functions and the same effects, which produce the same effects, also belong to the protection scope of this technical solution; the pump provides power for the circulation of oil products; the filter device is the core component of the filter system, which can filter out moisture, particulate matter and other substances in the contaminated oil products to achieve the effect of purifying the oil products; the oil pressure sensor is used to detect the pressure difference of the filter device; the second controller 201 is used to receive instructions issued by the comprehensive monitoring box 1 to control the operation of the filter 2;

[0040] The side of the filter 2 is connected to the integrated monitoring box 1 through a circuit (not shown in the figure), which plays the role of power supply and data transmission.

[0041] The utility model's system of online oil monitoring and linkage control of the filter is applied to lubrication systems such as hydraulic, circulation, bearings, gear boxes, turbines, etc. It can not only realize online monitoring of key parameters (water content, water activity, viscosity, density, particle size, composite dielectric constant, oil temperature, etc.), covering the most common system contamination, oil degradation, excessive water content and other problems, and overall characterize the lubrication health status of the hydraulic and circulation systems, but also realize automatic linkage filtering system to filter contaminated oil.
