Instruction Manual for Intelligent Cutting Fluid Filling System

Overview
Our independently developed and manufactured intelligent cutting fluid filling system can prepare cutting fluid in proportion to fill cutting fluid conveniently, rapidly and quantitatively.
The intelligent cutting fluid filling system consists of a cutting fluid mixing controller and a cutting fluid filling cart. The cutting fluid mixing controller mixes tap water and cutting fluid stock solution according to the set ratio, featuring a wide configurable concentration range and adjustable proportion; the cutting fluid filling cart is used to fill cutting fluid conveniently, rapidly and quantitatively. Used together, they realize automatic mixing and quantitative filling of cutting fluid.
The intelligent cutting fluid filling system solves the problems of labor fatigue and cutting fluid overflow and waste caused by the traditional manual pouring method for adding cutting fluid to machine tools. Especially when the water tank is installed under the machine tool, filling can be performed without shutting down the machine, reducing labor and downtime. It is suitable for all types of machining factories.
1. Scope of Application
This product is suitable for filling cutting fluid for various machine tools.
This product can be extended to other occasions requiring liquid filling.
This product is prohibited from being used for filling flammable and explosive liquids such as gasoline and alcohol, and is not applicable to liquids prone to rust and corrosion, such as water and aqueous solutions containing chemicals.
2. Working Principle

Cutting fluid mixing controller (mixer): When tap water flows through the mixer, the mixer draws in the cutting fluid stock solution according to the flow ratio and mixes the tap water with the cutting fluid stock solution. The mixer is wirelessly connected with the filling cart to realize automatic shutdown after the filling cart is full.
Cutting fluid filling cart (filling cart): Set the filling capacity, press the start button. The cutting fluid passes through the filter, water pump, liquid feeding pipe and filling gun to fill cutting fluid into the machine tool water tank, and stops automatically when the set outlet volume is reached. When the gun head of the filling gun is immersed in the liquid surface, it will automatically jump to stop, avoiding waste.

5. Installation Instructions

1. Installation Instructions for Cutting Fluid Mixing Controller (Figure 4)
1.1 Remove the upper cover, fix the bottom plate on the wall. It is recommended that the lower edge of the bottom plate be 1.5 meters above the ground;
1.2 Plug in the solenoid valve control wire, then reassemble the upper cover and the bottom plate;
1.3 Install one end of the water inlet pipe to the water inlet, and connect the other end to the tap water pipe;
1.4 Install the free end of the stock solution pipe to the stock solution port, and place the other end in the stock solution barrel;
1.5 Install one end of the liquid outlet pipe to the liquid outlet, and place the other end at the water filling port of the filling cart;
1.6 Connect the power supply and close the leakage protection switch.

6. Operation Procedures and Precautions
1. Adjust cutting fluid concentration: When using for the first time, turn the concentration adjusting handwheel of the mixer to adjust the mixing concentration of cutting fluid to the required concentration.
2. Fill cutting fluid into the filling cart: Unscrew the cover of the water filling port, insert the liquid outlet pipe, press the start button of the mixer to fill cutting fluid into the filling cart (the liquid level observation window on the front panel of the filling cart can check the water level). When the water tank is full, the indicator light will turn on and filling will stop automatically.
3. Fill cutting fluid into machine tool
3.1 Turn on the power switch of the filling cart;
3.2 Set the total amount of cutting fluid to be filled and click the start key;
3.3 Take out the filling gun, pull out the liquid feeding pipe to a proper position and fill cutting fluid;
3.4 After filling is completed, the water pump stops automatically, retract the liquid feeding pipe and filling gun, and turn off the power switch.
4. Precautions
4.1 After the mixing concentration is adjusted, no adjustment is required for subsequent use.
4.2 During mixing, press the stop button to stop mixing cutting fluid.
4.3 If quantitative filling is not set for the filling cart, the water pump will keep working after clicking the start key. After filling, you must click the stop key.
4.4 When the storage battery voltage is lower than approximately 22.5V, undervoltage alarm will be triggered and the whole machine will power off after 1 minute. Please charge it in time; do not charge it while the machine is powered on.
4.5 Use is prohibited when the air temperature is lower than 0℃. The water pump, filter and pipelines must be drained to avoid frost cracking.
7. Maintenance
1. The main power supply must be disconnected before electrical maintenance. Live disassembly and repair are strictly prohibited.
2. When the mixer is working, the reading of the water inlet pressure gauge must not be less than 0.1MPa. If the inlet water pressure fluctuates greatly, adjust the cutting fluid concentration to an appropriate range.
3. Manually test the leakage switch once a month to check whether it works normally.
4. The filling cart is equipped with a built-in storage battery. Please fully charge it before first use; during idle period, charge it at least once a month to prevent battery damage.
5. Keep the filling cart clean and avoid sundries and impurities in the filled liquid.
6. Clean the water pump filter element regularly (once every 3 months is recommended). Replace it immediately if it is damaged. (Use without filter element is prohibited.)
