The pump housing 1 contains a mixing chamber 3 and a hydrodynamic assembly 4, which communicates with the mixing chamber 3. A proportional regulating valve 5 is installed at the bottom of the hydrodynamic assembly 4, and an additive inlet pipe 6 is fixedly installed at the bottom of the proportional regulating valve 5. The hydrodynamic assembly includes a motor piston 41 and a proportional injector piston 43 respectively installed on the upper and lower sides of the mixing chamber 3, and an inlet pipe 45 and an outlet pipe 47 respectively installed on the left and right sides of the mixing chamber 3. The inlet pipe 45 and the outlet pipe 47 pass through the pump housing 1 and communicate with the mixing chamber 3. The inlet pipe 45 and the outlet pipe 47 can be respectively located on the left and right sides of the middle position of the pump housing 1. The cutting fluid input through the proportional regulating valve 5 is input into the mixing chamber 3 via the proportional injector piston 43, mixed with the water input through the inlet pipe 25, and then discharged through the outlet pipe 47.

[0031] The device is installed on a water pipe network using a structure consisting of a motor piston 41, a proportional injector piston 43, an inlet pipe 45, and an outlet pipe 47. The only power source is water pressure. Driven by water pressure, concentrated reagent is drawn in according to the desired quantitative mixing ratio and then mixed with water as the working medium. The resulting solution ensures that the volume of concentrated reagent injected is always proportional to the volume of water passing through the device, regardless of changes in water flow or pressure in the water network.

[0032] The proportional regulating valve 5 can be installed at the bottom of the pump housing 1, and the vent valve 2 can be installed at the top of the pump housing 1.

[0033] The inlet pipe 45 and outlet pipe 47 are located on the same horizontal line, which can ensure a stable water flow and reduce the impact of turbulence on the accuracy of the mixing ratio. A scale plate 12 is provided at the lower end of the pump casing 1. The scale plate 12 displays the liquid level or flow rate to help operators monitor the mixing process.

[0034] In one embodiment, see again Figure 1 A water inlet cover 451 is provided on one side of the water inlet pipe 45, and the water inlet cover 451 is detachably threaded to the end of the water inlet pipe 45. A water outlet cover 471 is provided on one side of the water outlet pipe 47, and the water outlet cover 471 is detachably threaded to the end of the water outlet pipe 47. Both the inner and outer sides of the water outlet cover 471 and the water inlet cover 451 are provided with an anti-corrosion layer. The anti-corrosion layer can be an anti-corrosion film. In addition to corrosion protection, the anti-corrosion film can also reduce the wear of the sealing ring and extend the service life of the components.

A sealing ring 456 is fixedly installed on the side wall of the buffer post 454, and the sealing ring 456 is movably disposed within the inlet cover 451, preventing liquid leakage from the seams of the inlet cover 451. Through the buffer post 454, sealing ring 456, and anti-corrosion membrane, the anti-corrosion membrane provides corrosion protection for the inlet cover 2. Tightening the inlet cover 2, under the action of the buffer post 17 and sealing ring 18, improves the sealing performance of the inlet cover 2.

[0036] In one embodiment, reference may be made to Figure 5 and Figure 6 The additive inlet pipe 6 has a threaded hole 61 on its lower inner side and a delivery hole 63 on its upper inner side.

Through the provided delivery hole, external thread, and internal thread, and the threaded connection of the suction tube 7 within the threaded hole 61, the suction tube 7 is easy to install and replace, and the raw rubber tape 71 ensures a tight seal at the connection point.

[0037] In one embodiment, see again Figure 1The pump housing 1 includes an upper pump housing 11, a lower pump housing 13, and reinforcing blocks 15. The lower pump housing 13 is fixedly mounted on the bottom of the upper pump housing 11, and the upper and lower pump housings 11 can be integrally formed. Reinforcing blocks 15 are provided at the connection between the lower pump housing 13 and the upper pump housing 11. Multiple reinforcing blocks 15 are provided and are fixedly connected to the lower pump housing 13 and the upper pump housing 11. The reinforcing blocks 15 are used to enhance the connection stability between the upper pump housing 11 and the lower pump housing 13 and prevent the interface from loosening due to pressure or vibration. The reinforcing blocks 15 are fixed to the outer wall of the pump housing 1 at equal angles to ensure uniform force distribution and improve the overall structural balance.

[0038] In one embodiment, see again Figure 2 A positioning block 14 is fixedly installed on one side of the outer wall of the pump casing 1. Two positioning screws 16 are installed on the positioning block 14. The positioning block 14 is fixed to the outer wall of the pump casing 1 by tightening the positioning screws 16. A hand-held block 18 is fixedly installed on the side wall of the positioning block 14. Through the structure of the positioning block 14, positioning screws 16, and hand-held block 18, the pump casing position is fixed by the positioning screws 15, and tightening the positioning screws 16 secures the positioning block 14, facilitating alignment during installation. The hand-held block 18 provides a gripping point, making installation convenient and easy for users to handle, move, and operate the equipment.

[0039] In one embodiment, reference may be made to Figure 7 The pump casing 1 includes a first anti-corrosion layer 1a, a first reinforcing layer 1b fixedly disposed on the inner side of the first anti-corrosion layer 1a, and a substrate 1c fixedly disposed on the side of the first reinforcing layer 1b away from the first anti-corrosion layer 1a. In one embodiment, a second reinforcing layer 1d is fixedly disposed on the side of the substrate 1c away from the first reinforcing layer 1b, and a second anti-corrosion layer 1e is fixedly disposed on the side of the second reinforcing layer 1d away from the substrate 1c. The first anti-corrosion layer 1a is provided to prevent corrosion of the pump casing by cutting fluid or the environment. The first reinforcing layer 1b is provided to improve the structural strength of the pump casing and resist internal pressure. The second anti-corrosion layer 1e is provided to enhance the corrosion resistance of the outer side of the pump casing and resist external environmental erosion. The second reinforcing layer 1d is provided to further improve the overall strength of the pump casing and ensure the long-term stable operation of the cutting fluid ratio control system. Through the structures such as the first anti-corrosion layer 1a and the second anti-corrosion layer 1e, the corrosion resistance of the inner and outer sides of the pump casing 1 is improved, and through the structures such as the first reinforcing layer 1b and the second reinforcing layer 1d, the overall strength of the pump casing 1 is improved. The base 1c serves as the main structural layer of the pump casing, connecting the anti-corrosion layer and the reinforcing layer, and providing mechanical support.

[0040] In one embodiment, multiple reinforcing rods are fixedly provided inside the first reinforcing layer 1b and the second reinforcing layer 1d. The reinforcing rods are embedded in the pump housing reinforcing layer to further improve the pressure resistance and deformation resistance. The reinforcing rods are made of high carbon steel. The advantages of high carbon steel are high strength and good wear resistance, making it suitable for long-term high pressure environment.

[0041] In use, the device is installed on a water pipe network. The sole power source is water pressure. Driven by this pressure, concentrated reagent is drawn in according to the desired quantitative mixing ratio and then mixed with water, which serves as the working medium. The resulting solution ensures that the volume of concentrated reagent injected is always proportional to the volume of water flowing through the device, regardless of changes in water flow or pressure within the water network. This solves the problems of existing mixing control devices, such as difficulty in accurately controlling the concentration and low mixing efficiency. For details, please refer to [link / reference]. Figure 3 Tap water is connected to the inlet pipe 45. The negative pressure of the tap water draws the raw cutting fluid from the raw cutting fluid storage tank. After passing through this device, the cutting fluid is mixed according to the parameters set by the proportional regulating valve 5. The concentration setting range is set according to actual working conditions, such as 2%-10%. The cutting fluid management personnel take samples to ensure the accuracy of the mixing ratio. The management personnel can use a saccharimeter to detect the concentration. The principle of proportional injection: Quantitative mixing according to a ratio requires no current energy source; the energy required for proportional injection is provided by the energy gathered from the water flow and water pressure. Measurement: The volume of the liquid is measured using a motor piston and a proportional injector piston. Proportional injection: Liquid concentrate or soluble concentrate is continuously injected proportionally, with mixing adjusted in a follow-up manner proportional to the water flow rate. The built-in proportional injector, capable of uniform mixing, is adjusted as follows: On the scale plate 12, align the upper part of the adjusting ring with the desired scale. This ensures that the amount of reagent to be injected is proportional to the amount of water entering the device. For example, adjust to 1% = 1:100 = 1 volume of medicine + 100 volumes of water.

[0042] To optimize the lifespan of the device, you can: install a filter upstream, with a resolution of 60 microns or 300 mesh, depending on the water quality in the pipeline; replace the gaskets of the proportional injector annually; flush it frequently with clean water; adjust the proportional injector without pressure; install necessary protective measures, such as flow restrictors, pressure limiters, and accumulators, to prevent overflow, overpressure, and water hammer; and install an anti-siphon valve upstream of the proportional injector in installations where siphoning may occur.

[0043] In summary, this utility model provides a cutting fluid proportioning control system. Through optimized structural design, it utilizes water pressure to achieve precise proportioning adjustment. The pump casing employs a multi-layer composite structure to enhance corrosion resistance and strength. Components such as the suction pipe and inlet cap are detachable for easy maintenance. The system has a compact structure, high proportioning accuracy, and is suitable for the metal processing industry.
