FLEK heat pump

Brief Overview of Flecker Thermal Energy Pump Flecker Thermal Energy Pump is a new type of technical equipment that converts power into thermal energy. This high-speed heat exchange technology is the principle of Nantong Flecker's application of fluid mechanics, which makes the fluid produce a large number of tiny bubbles in the high-speed cavitation generator, and then continuously produce strong micro-explosion phenomena such as expansion, compression and collapse in the vacuum negative pressure. The explosion process takes less than 6‰ seconds, at the same time, huge energy is released instantly to raise the temperature of the liquid to the boiling point. At the same time, due to the "cavitation effect", the material composition and scaling conditions that are easy to scale in the water are destroyed. Therefore, the impurities in the water will not agglomerate and scale due to the friction and heating of the water molecular chains, and will not generate turbulence under high-speed kinetic energy. The high-temperature water produced by the thermal pump is transported to the storage tank, pumped by the high-temperature water to each heat sink, and then returned to the storage water tank for secondary circulation, and the thermal energy conversion efficiency of the thermal pump can reach 95%. Examples of applications of thermal energy pumps 1. Heating can be carried out according to the actual utilization time of the building. One thermal energy pump has a model of RNB-40, a motor power of 45kw, and a low-valley power consumption of 8 hours. The stored heat can meet the requirements of ~ 800m ² office heating, ~ 500m ² residential heating and ~ 600m ² commercial facilities heating. 2. A gas station in Sinopec has a construction area of ~ 800m2, using a thermal energy pump, model: RNB-40, motor power: 45kw, and a 4m heat preservation water tank to form a heat storage heating system. The gas station uses the low-point electricity at night to run and store heat, heat the water tank to 90 degrees C for insulation, and use these hot water for heating during the day. When the weather is too cold, the heater is started to compensate for part of the energy during the day, and its cost is significantly reduced. 3. Use heat pump to produce domestic hot water with low valley power. One heat pump model: RNB-40, motor power: 45kw, low valley power consumption: 8 hours. The stored heat can meet the shower needs of 250~300 people. 4. It is also very convenient to use heat pump in swimming pool. Generally, the average loss of swimming pool is about 2 ℃ per day. Different unit configurations can be selected according to different water consumption of swimming pool, in the trough electricity at night to increase the water temperature insulation, you can also use the trough and the two sections of the flat peak to heat the water temperature. Instructions for the use of Flecker heat pump 1. First, install the Flecker heat pump on the indoor horizontal concrete floor, pad the anti-vibration rubber pad and fix the machine base with the corresponding hole diameter expansion screw. Connect the compensation water pipe of the thermal energy pump and the outlet of the hot water pipe produced by the thermal energy pump is connected with the inlet of the high temperature water pump. The water pump delivers hot water to each heating system (or hot water storage tank) for recycling, and the return water pipe is connected with the return water pipe of the heat pump water storage tank. 2. Turn on the power supply, open all valves, start the water pump after the water enters the thermal energy pump water storage tank, first transfer the water to each heating system through the water pump for circulation, check whether there is leakage at each water pipe interface, and then start the thermal energy pump motor after the return water enters the thermal energy pump water storage tank, and the motor turns to operate as shown by the arrow. If it is found that there is water leakage at the connection between the pump head of the heat pump and the bearing seat, it indicates that the mechanical seal in the pump casing is broken, please replace it in time. 3. After the thermal energy pump operates normally, first check whether the current and voltage are normal, then check whether the pressure of the water storage tank on the control box panel is displayed in a non-pressure state and whether the temperature is displayed in a rising state. If there is any abnormality, please contact Nantong Flake After-sales Service Department: 1772165850118962835399

Graphene production complete equipment

The general situation of graphene production equipment At present, the preparation methods of graphene production are mainly mechanical method, oxidation method, substrate growth method and liquid phase method, etc. Most of these production technologies and methods have disadvantages such as low yield, high energy consumption and poor quality, thus stopping the production and development of graphene in China. After unremitting efforts, Nantong Fulack Graphene Production Research Group has invented a graphene production line that integrates high-speed dispersion, crushing and grinding, vortex cavitation and shear ultrasound, which directly disperses graphite sheets continuously in liquid phase and continuously peels off graphite sheets. It has realized the production of high-quality graphene through mechanical shearing, hydraulic cavitation and other technical means, which is favored by the majority of graphene manufacturers. Graphene production equipment is a high-tech advanced equipment that uses mechanical hydraulic shearing and cavitation to peel off graphite sheets to produce high-quality graphene such as single-layer and multi-layer. The invention and application of this advanced technology has accelerated the pace of graphene production to a certain extent, and also promoted the confidence of graphene manufacturers to carry out large-scale, high-efficiency, low-cost, and pollution-free production. Moreover, this production process of mechanical hydraulic shearing and cavitation vortex stripping graphite sheet has the characteristics of simple operation, safety and reliability, no oxidation, no high temperature, and high quality products, which is very suitable for large-scale production of high-quality graphene. Graphene production equipment process flow graphene production process flow: first, graphite powder, dispersant or surface modifier and water are mixed in a high-shear dispersion mixing batching tank for dispersion and stirring, first close the circulation valve and then open the connecting valve between the storage tank and the dispersion grinding pump, so that graphite solution enters the high-shear cyclone ultrasonic accumulator through a fine dispersion grinding mill and a hydraulic shear vortex cavitator and then enters the process of high-shear cyclone ultrasonic accumulator through pressure. When there is no material in the batching tank, the lower connecting valve will be automatically closed and the circulating valve will be opened to allow the graphite solution to continuously circulate and peel off the sheets so that the graphene single layer and multi-layer can achieve the desired effect. The pressure control, time control and temperature control designed in the integrated control system can also be controlled by computer or touch frequency control or full-automatic control.
