CHV 110 Series Energy Saver for Injection Molding Machines

CHV 110 series energy saver is specially developed for injection molding machines which is applicable to all brands of injection molding machines with metering pumps. It can modulate the flow of oil pump to meet different flow and pressure need in different working period so the energy will be eliminated dramatically in the cooling period. The successful installation of totally 15,000 sets guarantees the confidence for users to select the product. Meanwhile, it can implement soft start of the motor, improve the power factor and reduce the oil temperature.

I. Product Features:

• Fast current limiting function, with an instantaneous impulse current as

high as 300% and an overload capability up to 180%/30 seconds; ensuring

normal operation under such heavy load as injection and no influence

upon the production efficiency; ensuring product quality;

• Automatic reset and power failure reset function, ensuring production

continuity and efficiency;

• Integrated structure with dual-loop conversion circuit of "mains supply" /

"energy-saving operation": ensure no system fault and no influence upon

production;

• With a protection grade of IP54, full-closed design, perfect dust-proof,

gas-proof, and corrosive-proof performance and strong environment

adaptability, prolonging the service life of the equipment;

• Multiple signal inputs: 0 ~ 1A, 0 ~ 10V, 4 ~ 20mA, 0 ~ 20mA, 0 ~ 10KHz,

for the convenience of control;

• RS-485 communication function;

• Unique PWM optimized design, efficient operation, with an energy-saving

efficiency as high as 25% to 60%

• Full range protection such as phase failure, overvoltage, undervoltage and

overcurrent

• Independent air duct design, providing better heat dissipation effect,

preventing electrostatic dusts from causing damage to electronic

components;

• Small size, easy to install, user-friendly structure design; compact

structure,

II. Energy Saving Principle:

For traditional injection molding machines with constant delivery pumps, valve

adjustment is required to change load flow rate and pressure. In this case,

input power changes slightly, and a large proportion of energy is consumed by

the valve in the form of pressure difference, causing overflow.

supply quantity of the oil pump based on the current working state of an

injection molding machine, like mold clamping, injection, melting, mold opening,

and ejector pin, and according to the set pressure and speed requirements, so

that the actual oil supply quantity of the oil pump can be consistent with the

actual load flow rate of the injection molding machine at any stage. As a result,

it minimizes the energy consumption when the motor operates in its load range,

eliminates overflow phenomenon, and ensures stable and precise operation of

the motor.

Application of CHV 110 energy saver makes soft start possible for the motor of

injection molding machines, improves the power factor COS of the motor, ∮

and dynamically adjusts the output power of the motor of injection molding

machines. In this way, the energy is saved.
