1.Before installation, three-phase AC 220V/50Hz or 380V/50Hz must be prepared;
2.High-pressure hose piping; one end of it is connected to the coolant outlet (Fig. 2) and the other end is connected to the coolant inlet of the main spindle;
3.Inlet piping, one end is connected to the recharge pump of the machine tool (Fig. 2) and the other end is connected to the inlet of the coolant tank;
4.Overflow piping, one end is connected to the overflow outlet of the coolant tank (Fig. 3) and the other end is placed on the coolant tank of the machine tool body;
Note: When the equipment is connected to power, the installer must follow the requirements of national regulations and safety instructions.
Before starting, please check the rotating direction of the high-pressure pump and the fan end, both of which should rotate counterclockwise.

1.The following signs are of great importance. You must follow the signs below and know their meanings to operate safely, avoid persona I injury and prevent damages to the plant facilities.
Pressure regulating process:
install tools in the machining center—>manually turn on the spindle coolant delivery
2.While moving and fixing the equipment, please be aware of the followings:
1)If a lifting method is adopted, please use the 4 lifting points on the equipment;
2)If a forklift is used, please make sure to lift from the bottom of the equipment;
3)While carrying, please s I ow down in case of falling;
4)Drain out all liquid in the equipment before carrying and transporting.
5)It* s forbidden to stand on the equipment;
6)Install this equipment on a flat surface;
1.Cutting fluid delivery can be divided into high pressure delivery and low pressure delivery. The low pressure is used to deliverthe coolant from the tank of the machining center to this equipment and the high pressure is used to deliver the coolant from this equipment to the tools in the machining center.
2.Low pressure delivery: the cutting fluid flows through the low pressure filter and enters the coolant tank. The coolant inlet pressure can be observed through the pressure gauge installed at the coolant inlet. If the pressure reaches 0.4Mpa, the coolant inlet filter needs to be replaced.
3.High pressure delivery: Coolant in this equipment is sent out by a high-pressure pump and then enters the integrated distribution valve. With the pressure gauge on the side of the valve body, the coolant outlet pressure is displayed. And there is an overflow valve for coolant outlet pressure adjusting.
system —►observe the coolant outlet pressure gauge—rotate the pressure regulating valve left or right to adjust. After adjusting, lock the lock nut on the pressure regulating valve.
4. Level control: The liquid level is detected by the high and low level switches. When it reaches the low liquid level detection point, the switch will be turned on and then send a signal to the numerical control system for refilling; when it reaches the high liquid level detection point, the numerical control system will stop refilling (This equipment has an overflow outlet. If the liquid level is higherthan the overflow outlet when the liquid level control fails to work, extra liquid can automatically overflow.)
1.When the coolant inlet pressure is high or the coolant tank level is slow to replenish, the inlet filter element should be replaced in time.
2.Use a wrench to open the sealing cap.
3. Pull out the filter element
4. Grease the sealing ring of the new filter element
5. Insert the new filter element and close the sealing cap
1. No coolant comes out from the tools of the machining center
1) Check whetherthe pump is running;
2) Check whetherthe overflow valve is working properly;
3) Check whetherthe coolant outlet pressure gauge is displaying normally;
4) Check whetherthe piping is leaking;
5) Check whetherthe motor is running counterclockwise;
6) Check the liquid level of the coolant tank;
2. Low coolant pressure at the tools of the machining center
1) Check whetherthe overflow valve is working properly;
2) Check whetherthe piping is leaking;
3) If the outlet pressure is OK, check whether the piping is bent;
4) Check whetherthe rotary joint of the main spindle is working properly;
3. Slow replenishing of the coolant tank
1) Check whetherthe fluid replenishing motor is working properly;
2) Check whetherthe coolant inlet filter element is blocked;
3) Check whetherthe coolant inlet piping is leaking;
