CNC 4KW 4000w 220V 5HP Variable Frequency Drive Inverter VFD for Spindle Motor Speed Control

Introduction

This VFD can be used for constant torque loads (such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as a motor speed control and a phase converter. The input for this VFD is 1 or 3 phases as you like. You can control the different speed .It can be used as a motor speed control and a phase converter.Many customer bought our VFD from us to use for:Lathes, Mills, Car Hoists, Pumps and Conveyors.

the radiator keeps your vehicle's engine cool during a drive; but when your radiator is leaking coolant, the engine can overheat and suffer serious damage. if you are far from a garage and your radiator is leaking, you can use eggs to patch small holes and temporarily plug the leaks. heat from the radiator will cook the egg whites, and pressure will force the eggs into the holes, fixing the leaks long enough to take your car to a garage for repairs.

allow the radiator to cool. test the temperature of the radiator by carefully touching the radiator hose; do not continue if the radiator hose is still hot.

step 2

cover the radiator cap with a towel or rag, and slowly twist the cap to open the radiator. let any steam dissipate before fully opening the radiator.

step 3

crack an egg gently into two halves over the bowl. pour the yolk back and forth between the shell halves, and let only the white run into the bowl.

step 4

pour the egg white from the bowl into the radiator.

step 5

repeat steps 3 and 4 for the remaining eggs. separate and pour the whites into the radiator one at a time; if you spill the yolk, you won't ruin all of the whites.

screw the cap radiator cap back into place, and make sure it is secure before starting your car.
