Description

Technical Field

[0001] The utility model relates to the technical field of machining center equipment, in particular to an intelligent constant-pressure central water outlet device. Background Art

[0002] In the modern machining industry, machining centers are essential, efficient production tools. However, many of the water outlet devices currently used in machining centers on the market have shortcomings. Most existing water outlet devices lack automated adjustment capabilities, often requiring manual intervention to adjust the water pressure. This not only reduces efficiency but also increases operational difficulty.

[0003] Traditional water outlet systems often fail to incorporate internal pressure fluctuation buffering measures in their design. This results in an inability to adjust promptly to sudden high pressures or sudden changes in demand, potentially damaging equipment or reducing processing quality. Furthermore, due to a lack of effective filtration, impurities within the system can damage precision components and shorten equipment life.

[0004] In view of the above problems, it is necessary to design a new intelligent constant-pressure central water outlet device to overcome the shortcomings of the existing technology. This application aims to provide an intelligent constant-pressure central water outlet device with stable high-pressure output, automatic adjustment capabilities, and efficient filtration functions. By adding an oil block and integrating components such as a diaphragm accumulator, a check valve, a throttle valve, and a relief valve, the above problems can be effectively solved, improving the operating efficiency and processing quality of the machining center.

[0005] Furthermore, while existing water outlet devices, such as the energy-saving, constant-pressure, high-pressure central water outlet system for machining centers disclosed in Application No. 2019107412645, achieve automated regulation and energy-saving effects to a certain extent, they still face some technical challenges. In particular, key components in these devices, such as the accumulator, relief valve, and pressure sensor, are typically located on the outer wall of the filter, resulting in a low level of integration. This results in a large overall device footprint, making subsequent maintenance and replacement inconvenient and increasing equipment management and repair costs. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0029] The utility model provides an intelligent constant-pressure central water outlet device.

[0030] In this embodiment, referring to Figure 1-4 The intelligent constant pressure central water outlet device includes a chassis 1, which is provided with a water inlet 2, a coarse filter cartridge 3, a pre-filter 4, a water pump motor assembly 5, a high-pressure filter 6 and an oil circuit block 7. The water inlet is connected to the water inlet of the coarse filter cartridge through a water pipe, the water outlet of the coarse filter cartridge is connected to the water inlet of the pre-filter through a water pipe, the water outlet of the pre-filter is connected to the water inlet of the water pump motor assembly through a water pipe, and the water outlet of the water pump motor assembly is connected to the water inlet of the high-pressure filter through a water pipe;

[0031] The oil circuit block is provided with a high-pressure flow channel 8 and an overflow channel 9, and the high-pressure flow channel 8 and the overflow channel 9 are connected through flow channel 1 10, flow channel 2 11 and flow channel 3 23. The water outlet of the high-pressure filter is connected to the water inlet of the high-pressure flow channel through a water pipe, and the other end of the high-pressure flow channel serves as a high-pressure water outlet 12. The flow channel 3 is connected to a diaphragm accumulator 13 and a pressure sensor 24. The flow channel 2 and the flow channel 3 are both connected to a plug-in check valve 14. The overflow channel is connected to a plug-in overflow valve 15 and a plug-in throttle valve 16, and one end of the overflow channel serves as an overflow port 17.

[0032] In this technical solution, by connecting the coarse filter cartridge, pre-filter, water pump motor assembly, high-pressure filter, and oil manifold block via water pipes, the entire process, from water inlet to high-pressure water outlet, is optimized. The high-pressure flow and overflow channels on the oil manifold block, combined with a diaphragm accumulator, check valve, throttle valve, pressure sensor, and relief valve, ensure the stability of the outlet water pressure, enhance the system's automated regulation capabilities, and guarantee outlet water quality through multi-stage filtration.

[0033] Among them, the pressure sensor is not only used to detect the pressure in the system, but also can achieve energy saving and consumption reduction through feedback information. Specifically:

[0034] 1. Automatic motor speed adjustment: A pressure sensor monitors system pressure in real time and transmits this data to the control system. When the system pressure is detected to be above the set point, the control system uses the inverter to reduce the motor speed, thereby reducing the pump's output flow. Conversely, when the pressure falls below the set point, the motor speed is increased to increase the flow rate and achieve the set pressure. This dynamic adjustment mechanism ensures that the system always operates at optimal conditions, avoiding unnecessary energy consumption.

[0035] 2. Reduce unnecessary power loss: Throughout the entire control process, the system achieves precise control of pressure, flow, and motor power through a closed-loop control system formed by a pressure sensor, inverter, and touch screen all-in-one machine. When high-flow, high-pressure water output is not required, the system automatically reduces motor speed to achieve a high and constant pressure, reducing unnecessary power loss and achieving energy conservation and consumption reduction.

[0036] 3. The high-pressure water outlet is equipped with precision filtration, and the filter is equipped with a pressure differential alarm, which is a good solution to the current unmanned workshop that can send out signal warnings in advance during 24-hour non-stop operation.

[0037] Diaphragm accumulators, located in high-pressure flow channels, primarily absorb water pressure fluctuations caused by pump startup and shutdown, as well as other factors. They store energy and release it when water pressure suddenly drops, stabilizing system pressure. This reduces pressure shocks to other system components, extends equipment life, and ensures stable water pressure during processing.

[0038] Cartridge check valves are installed on flow channels 1 and 2 to prevent reverse flow of high-pressure water. This means that when high-pressure water flows through the flow channels, the check valves prevent the water from flowing back in the opposite direction, ensuring the correct flow direction and preventing system pressure drops or instability.

[0039] The cartridge relief valve is installed on the overflow channel. Its main function is to open when the system pressure exceeds a predetermined value, allowing excess high-pressure water to flow out through the overflow channel, thereby protecting the system from excessive pressure. This prevents the risk of damage caused by system overpressure and ensures safe operation of the system.

[0040] A cartridge throttle valve, also located on the overflow channel, regulates the flow rate through the channel. By adjusting the throttle valve opening, the flow of high-pressure water entering the overflow channel can be controlled, indirectly regulating the operating pressure within the system. This helps the system maintain the desired pressure level under varying operating conditions, enhancing its flexibility and adaptability.

[0041] In general, the highly integrated hydraulic block improves equipment integration, reduces equipment size, and eliminates the additional space required for independent installation, making the entire system more compact. Furthermore, the integrated design helps better coordinate the interactions between components, improving system stability and reliability, ensuring a stable high-pressure water flow under various operating conditions, and promoting improved processing precision and efficiency.

[0042] Specifically, a sewage outlet 18 is provided at the bottom of the coarse filter cartridge.

[0043] The bottom of the coarse filter cartridge is equipped with a drain port. This design allows users to regularly clean out impurities and dirt inside the coarse filter cartridge, maintaining system cleanliness and reducing maintenance issues caused by impurity blockage, thereby further ensuring the stable operation of the water outlet device.

[0044] Specifically, a roller 19 is provided at the bottom of the chassis.

[0045] The installation of rollers on the bottom of the chassis enhances the mobility and flexibility of the water outlet device. This is very useful in processing environments that require frequent position adjustments, allowing for quick rearrangement of the work site and improving the ease of use and space utilization of the equipment.

[0046] Specifically, the water pump motor assembly includes a motor 20 and a high-pressure water pump 21; the water pump motor is fixed to the bottom of the chassis by bolts, and a rubber shock-absorbing pad 22 is placed between the water pump motor and the chassis.

[0047] Rubber shock-absorbing pads are placed between the water pump motor and the chassis. This design not only firmly mounts the water pump motor assembly and reduces vibration during operation, but also reduces noise and improves the operating environment, thereby enhancing the overall performance of the equipment and the user experience.

[0048] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
