Product Description:

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.

CHV110 energy saver can automatically adjust the rotation speed and oil 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 CHV110 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.

Control method:

The price of product is depend on power rating of injection molding machine motor. Preferential price:RMB750/KW, including mounting and debugging fee and tax. For example, the investment of restructure of a Toshiba IS350 injection molding machine motor can be calculated as below:

45KW X RMB750/KW = RMB33,750¥/pcs.

Generally, we can call back all cost of the reconstruct via saving energy in 6-12 months. The energy saving is design for oil pump, calculate correlative cost of Toshiba IS350 45KW injection molding machine motor as follows.

I. Before reconstruct.

The dissipation of injection molding machine have consanguineous relationship with performance of motor, mould and material. In our reconstruct experience, actual consumption is about 55% dissipation of motor with 60% load. As a result, the oil pump motor dissipation can be calculated:

　　45KW　X　55%　＝　24.75(kWh/h)

Electricity price RMB 0.85yuan/kWh, running time is 30 days a month, each day work 20 hours. every month saving cost of motor is about:

24.75kWh/hX30dayX20hX ￥0.85 yuan/kWh＝￥12,622.5yuan/month

II. After reconstruct.

After reconstruct, the injection molding machine average saving energy rating is 30%, Customer reclaim effects every month is:

￥12,622.5 X 30% = ￥3,786yuan/month

reclaim effects every year:￥3,786yuan/month X 12 = ￥45,432yuan.
