In modern society, domestic and commercial sewage treatment plants are common.

Frequency inverters from our company are widely used in municipal engineering for waste water treatment (sewage disposal, sewage treatment, sewage sludge treatment), such as sewage pumping and sludge dewatering.

Variable speed drives from Shenzhen V&T Technologies Co., Ltd. are an ideal way of regulating flow and pressure. The main benefit of using inverter drives in this field is energy saving. Also, smooth control during operation is achieved.

our VFD drives can help you to make significant energy savings when compared to traditional regulation methods.

For example, compared to a throttle-controlled fixed speed pump, energy savings of 50% are typical. Thus the payback time of the investment on VSD drives is sometimes just one year, even shorter.

illing operations cover from small individual parts to large, heavy-duty gang milling operations.

It is one of the most commonly used processes in industry and machine shops for machining parts to precise sizes and shapes.

The milling machine is a kind of machine tool for machining various surfaces of work piece with milling cutter. It's widely used in machinery manufacturing and repair departments.

Two types generally: vertical and horizontal mill.

Why use our vector control frequency inverters for milling machines?
Some advantages include:
excellent control effection.
large torque at low frequency (necessary features for slow speed operation).
quick dynamic response.
excellent stable-speed performance.

The rapid growth of the extrusion industry has increased the demand for extrusion machines and accessories.

Extrusion process, including hot extrusion, cold extrusion and hydrostatic extrusion, is useful in the creation of objects of various shapes like solid round, rectangular, etc.

Various extrusions machinery include Extruder, PP / TQ Film Plant, Extrusion Lamination Plant, Synthetic String Plant, and so on.

Plastic extrusion is very common, and involves melting and forming of raw plastic material into pipe / tube, window frames, adhesive tape, etc.

There are various types of plastic extruders, such as basic extruder machine, single screw extruder and twin screw extruder. These extruders are used to manufacture a wide range of products by extruding an assortment of plastic materials.

Variable frequency drives are widely used for retrofitting of plastic extruder machinery, mainly for reducing the energy consumption, thus saving the energy bill.

Available voltage range:
380 VAC - 480 VAC (323 VAC - 528 VAC): 380 V, 400 V, 415 V, 440 V, 460 V, 480 V

Power range:
11kw ~ 132 kw (15hp ~ 176hp)

25% - 70% energy saving, general above 50% energy saving with the existing parameters.
Improve environmental and production efficiency.
Lower noise levels.
High response.
Long service life and less maintenance cost.
Easy to install, no need to replace the existing motor and oil pump. The total cost of our asynchronous servo drive is 70% lower than synchronous servo drive.

For injection moulding machines, our servo drives allow injection molding machine hydraulic systems to vary the amount of fluid being pumped. This reduces the amount of fluid that is throttled and reduces the amount of wasted energy.

Applications:
injection moulding machines, die casting machines.
