WIN-HV inverter speed adjustment principle and applications

The load characteristics of the vane-type pump, fan and compressor are all of square torque type, which means the torque on the axis is proportional to the square of the motor speed. The pump and fan conform to the similarity theorem on condition of geometric similarity, movement similarity and power similarity. Taking a fan (or pump) as an example, if its speed is to be adjusted while the consistency of the transmitted liquid remains constant, its performance parameters will change following the proportion theorem, the flow quantity is proportional to the speed; the pumping head is proportional to the square of the speed; and the axis power is proportional to the cube of the speed. But in actual operation, it is inaccurate to compute the speed control range and energy saving efficiency simply by the said proportion theorem due to different system parameters and operating status.

2. Energy saving principle of pumps:

Different from fans, the static pumping head of pumps Hst≠0. The outlet pressure (pumping head) of pumps is required to maintain constant in most occasions. The pump’s energy saving principle can be represented by the diagram 2.

When decreasing the flow quantity from Q1 to Q2 by the valve, the pump speed maintains its rated speed N1, but the pipe network resistance curve (1) will change to the curve (2), leading the working intersection A to change to B. At this time, the consumed axis power can be represented by the area of H1BOQ2, almost the same to that of H2AOQ1, resulting in huge energy to be wasted.

When the inverter is installed, it can decrease the pump speed from N1 to N2 with the pipe network resistance curve (1) being unchanged, so the working intersection A transfers to C. At this time, the consumed axis power can be represented by the area of H3COQ2. Compared with H1BOQ2, it is easy to find out that the inverter has prominent energy-saving capacity.

Fig.2 Energy saving elementary diagram of pumps


20

1. Energy saving principle of fans:

As the fan’s static pressure Pst=0, its energy saving principle can be represented by the diagram 1.

In the diagram 1, the curve (1) represents the wind pressure and wind quantity characteristics curve (P-Q) at rated speed N1. The curve (2) is the pipe network resistance characteristics curve when the air valve is widely open. The intersection A of the curve (1) and (2) indicates the point at which the motor runs with the highest efficiency. At this time, the wind pressure is assumed as P2, the wind quantity is Q1, and the axis power N1=k*Q1*P2, which can be represented by the area of AP2OQ1.

On condition that the wind quantity is to be decreased from Q1 to Q2 according to production requirements:

If adjusting the wind quantity by the valve, it will increase resistance of the pipe network, resulting in the pipe network resistance curve to change to the curve (3), and the intersection A change to B. At this time, the wind press is assumed as P1 and wind quantity is Q2, so the axis power N2 = k*Q2*P1, which can be represented by the area of BP1OQ2. Compared with AP2OQ1, it is easy to find out that the axis power decreases just a bit.

When adopting the inverter to conduct speed adjustment, the fan speed will reduce from N1 to N2. As the fan’s static pressure Pst=0, conforming to the similarity theorem, the wind pressure and wind quantity characteristics curve(P-Q) at the speed N2 can be represented by the curve (4), which converges the curve (2) at point C. At this time, the wind pressure is assumed as P3 and wind quantity is Q2, so the axis power N3=K*Q2*P3, which can be represented by the area of CP3OQ2. It is easy to draw a conclusion that N3 decreases steeply due to hefty decline of wind pressure.

Compared with the valve control mode, the inverter can help save huge energy. The saved axis power N=K*(P1-P3)*Q2, which can be represented by the area of P1BCP3.

In most of the power plants, the induced draft fan of boiler furnace commonly runs at a constant speed with power frequency. It is wasting quite lots of electricity in the process of adjusting the wind quantity via the valve. The 200WM generator usually runs with peak shaving, with huge valley-to-peak difference. When WIN-HV inverter is installed, the induced draft fans get access to realize speed adjustment, as well as wind pressure and wind quantity control no matter whether the valve is open or not. Accordingly, WIN-HV inverter is able to help the power producer save energy and cut cost, with energy-saving rate of 20%~70%.

Strengthen reliability of the equipments

The installation of WIN-HV inverter realizes soft starting in a real sense,eliminates huge surge current and mechanical wear abrasion so as to prolong the life of the equipments. Low-speed operation reduces the fan’s vibration and the bearing’s wearing, thence the reliability of the equipment is improved.

Reduce maintenance and repair cost

WIN-HV inverter can help the user reduce maintenance and repair cost as it eliminates huge surge current and mechanical wear abrasion.

Enhance automazation level

WIN-HV inverter is equipped with several external signal and computer interfaces, which enable the inverter convenient to connect with the control system PLC, DCS &FCS, communication system, energy management system and other management system. It greatly enhances the machines’ roboticized control and management level.

Relieve labour intensity

On condition of the load changed, it is very inconvenient to adjust the wind quantity by changing the valve opening. And this control mode has poor linearity and high fault rate. In contrast, when adopting WIN-HV inverter, it can adjust the speed of the fan by regulating the fan’s motor frequency. It is much easier to operate, with perfect linearity and control sensitivity.
