PTI-P fan pump inverter Features ● excellent soft-start and soft-stop function, reduce motor starting current, reduce the impact of the current impact of the grid to protect the motor, anti - water hammer pump stop; ● optimize the production process, so that gas and liquid flow, velocity, pressure is more reasonable; the system uses closed-loop control parameters overshoot fluctuation - a small range, acceleration and deceleration can be automatically adjusted according to process requirements; ● very sensitive fault detection, diagnosis, digital display, improve motor operational reliability; ● user selectable with or without a "work / frequency switching", convenient; ● After having remote automatic control RS-485 interface for remote control; ● Short circuit, overload perfect protection, overheating, etc. Function; ● good energy-saving effect, according to the site to process requirements are inconsistent, energy-saving rate of 20% -50%. Application The product is widely used in industry, heating boilers, cement kilns, coal, metallurgical industry blast furnaces, converters, chemical plants, pharmaceutical plants, sewage treatment plants, oil fields, petrochemical plants, water supply companies and other industries, enterprises and occasions frequency control and flow of centrifugal fans, axial fans, Luoci fans, air compressors, centrifugal pumps, submersible pumps, circulating pumps, submersible pumps, pump, high-pressure injection pumps and other equipment, flow rate and pressure regulation control. PTI-F special textile inverter knitted fabrics in the dyeing and finishing processes are inseparable from the heat and compressed air. There are two kinds of heat energy steam and thermal oil as the heat medium. Steam heat supply equipment such as dyeing process and dyeing process of high temperature and pressure dyeing machine, at room temperature dyeing machine, pull the cylinder and so on. HTF as a medium of energy supply drying equipment, such as a finishing process of printing machine, dryer, resin stereotypes and other equipment. Steam heating boiler at high fuel prices, most coal-fired boilers. Coal-fired boiler induced draft fan, blower, adjust the air volume in the past are used to adjust the throttle after the use of frequency control technology, you can adjust the motor speed to adjust the fan flow purposes. Similarly to the boiler feed pumps, using the frequency adjustment to pump flow to constant level continuous water supply. Case with 15 tons of coal-fired boilers, Fan 90KW, frequency inverter run at 40HZ; blower 45KW, frequency inverter run around 40-50HZ; feed water pump 30KW, frequency inverter run at 40HZ. Gas pressure of the boiler can be stabilized at around 1MPA. This would ensure that the dyeing machine required 0.5-0.7MPA pressure steam heat, dyeing 40-50T knitted fabrics production. PTI-Q inverter professional ball mill is the cement industry, ceramic industry, mining and mineral processing industries indispensable equipment, but also the three biggest share of power industry equipment, the production of electricity consumption accounts for about 40 % -50%. In ensuring production quality, under the premise of production is not affected, how to reduce the mill's power consumption has been an issue in these three sectors investor concern. Saving transformation of a ball mill, to reduce production costs of these three sectors, increase profitability of great significance. How it works: In the cement industry, ceramic industry, mining and mineral processing industry, ore crusher preliminary first by crushing, fine crushing to a reasonable degree after fed into the mill first warehouse, there are ladder liner or corrugated liner in the warehouse board, there are different specifications of steel balls appointed chest, when the cylinder is rotated, the ball due to the centrifugal force is a certain height and then fall, food line was pounding and grinding of the bins. Thus, large pieces of material to complete the first step of roughing in the first barn. Complete the coarse grinding of materials through a single-layer diaphragm plate into the second position, in this warehouse lined with flat lining, which also has a lot of balls, where the material will be further milled, this step is termed class finely ground. After these two steps of the job, the original chunk of material become largely been milled powder, and finally the powder material is discharged through the discharge grate plate to complete the grinding operation. Centrifugation speed control system existing grinding speed and grinding balls is constant, grinding time is generally set based on experience, and requires a large starting torque is started when a ball mill, a large inrush current. Our professionals through a lot of experiments and research, on the running track and the force balls decomposition, with frequency technology on the entire work process mill track sampling, developed a special ball-watt energy-saving control cabinet. Watt energy-saving ball mill control cabinet with frequency of way, by adjusting the speed of the motor, the output torque and speed of the ball mill process requirements of the motor to achieve the best fit, then it will increase the mill's efficiency and optimize the mill's production craft, but also greatly reduces the mill's power. Features: ● Excellent soft start, greatly reduce the mill starting current, to avoid tripping under control with the original occurrence; ● improve mill efficiency, optimize production processes; ● speed grinding of all time according to production process requirements set convenient; ● After saving rate: According to the production process requirements are different, saving rate of 10% -20% PTI-Z drive injection molding machine Professional Overview: In the plastics industry, injection molding machines, blow molding machine is the main production equipment, power consumption, but also very serious waste of electricity. How to reduce injection electromechanical energy consumption has become an important research topic in many plastics companies. Injection molding machine working process is divided into mold clamping, sol, injection plastic, Paul several stages, cooling, mold, ejector, etc., working pressure and flow needed for each stage are different, and there are some changes in the law . Hydraulic pump oil flow provided by the injection molding machine, the pressure is constant, but most of the time of the injection molding machine during operation are less than the actual pump flow and pressure constant flow and pressure. Excess hydraulic oil through the relief valve is returned to the storage tank, which not only caused the hydraulic oil temperature, and waste a lot of energy, particularly in the "cooling" This process is most serious. How it works: Dr. Paul-saving injection molding machine control cabinet for the technical characteristics of plastic industry injection molding machines, blow molding machines and other processing equipment, injection molding machine control flow and pressure variation signal acquisition, automatically adjusting the pump motor speed, and then adjust the pump for fuel, so the actual amount of oil pump injection molding machine actual load in any work processes are consistent. Eliminate the overflow of hydraulic oil heat, thus making quantitative pump injection molding machine instead of the variable displacement pump, so that the injection molding machine without affecting the yield and quality of produce, both extending the life of the pipeline, but also saves the pump motor power consumption. Product Features: ● Frequency microcomputer control technology, without changing the existing injection molding machine control mode and the oil; ● excellent soft start and soft stop function; ● fault automatic bypass, saving / bypass switch freely; ● saving pump The oil and cooling water consumption and extend the life of pumps and pipelines; ● saving rate is high, so that the pump motor energy-saving rate of 20% -45%
