Machine characteristics

Can reduce energy consumption

The traditional quantitative pump is changed into a variable pump by using a bending machine frequency conversion cabinet, and the high-frequency and low-voltage double-signal input frequency conversion speed regulation method is adopted, which replaces the previous valve speed regulation method, and the energy consumption is greatly reduced.

Extend machine life

The hydraulic machine energy-saving cabinet device adopts external expansion synchronous control, and the arbitrary speed segment can be adjusted at will, which can conveniently meet the requirements of the hydraulic process and achieve the optimal value, so that the production process is improved than before. And can reduce the system oil temperature, extend the life of the sealing components, reduce equipment maintenance costs

Easy to control

The bending machine energy-saving cabinet device adopts advanced computer control means, uses the synchronization signal of the hydraulic machine computer, automatically controls the oil pump motor according to the process requirements of the bending machine, and the operation is safe and reliable. The hydraulic energy-saving cabinet is not required to be adjusted during production, and the control operation is convenient. simple

No throttling energy loss, oil temperature reduction

Without throttling energy loss, the overflow energy loss is greatly reduced, the system noise is reduced by 3-5 decibels, the tubing heat is reduced, and the oil temperature is lowered.

High reliability

Bending machine energy-saving cabinet speed control device can realize power frequency / frequency conversion, even in the case of frequency conversion failure, can be converted to power frequency, will not affect the production progress. The lifting torque is large and the dynamic response is fast, which is suitable for the sudden increase of the speed of the hydraulic machine.

Frequency conversion energy saving

Frequency conversion energy saving, it is still inefficient and simple in energy saving effect, but it is economical and can make less noise.

The structural principle of the machine

Energy saving and consumption reduction is an important part of the bending machine

With the wide application of bending machine equipment, electricity consumption is an important part of the production cost for the hydraulic equipment industry, and the bending machine is one of the main energy-consuming equipment, so reducing the energy consumption of the bending machine becomes the factory. An effective way to reduce costs and improve product competitiveness.

Energy saving

Pump control servo energy saving principle

The frequency conversion speed regulating device is composed of a rectifier circuit, a filter circuit, an inverter circuit and a control circuit. Its function is to rectify and filter the AC energy into DC power through the rectification link, and convert the AC power into different frequencies through the inverter link. Motor. Therefore, the hydraulic oil pump motor can be operated at different speeds, and the energy saving efficiency is as high as 20% or more.

Where is the power consumption of the bending machine?

The electric energy consumption of the bending machine is mainly reflected in the electric energy consumption of the hydraulic system oil pump. The electric power consumption of the hydraulic oil pump accounts for more than 97% of the total electric power consumption of the hydraulic machine, so reducing the power consumption is the key to the energy saving of the hydraulic machine. The hydraulic machine needs to change the pressure and flow rate during the rapid down, slow down, pressure holding, pressure relief return, piston ejection, piston retraction, buffer cylinder ejection, etc., when the pressure demand of the press brake changes. The load pressure and flow are regulated by a relief valve located at the outlet of the oil pump, and the output power of the motor is constant, thereby wasting energy.
