First, the Nikon vortex pump introduced 1. Features: ◆ small size, high pressure, save installation site Single Impeller can get 4-17 kg of pressure, two impeller can get up to 30 kg of pressure. Due to its small size and simple structure, miniaturization and cost reduction of the mechanical device can be realized. ◆ Small flow can also be stable liquid because it is not a positive displacement pump piston pump, eddy current pump does not produce pulsations. In the meantime, since the vortex pump has little change in flow rate under different pressure conditions, there is no need to return the flow in the small flow range like the centrifugal pump, which not only can realize the miniaturization of the equipment but also can reduce the equipment investment and operation cost. ◆ Quantitative vortex pump is not a positive displacement pump, but its flow rate has little change when the impedance of the pipeline increases or decreases, which shows good quantitative performance. ◆ Durability Nikon vortex pump and Other manufacturers of similar products, the biggest difference is that the impeller fixed to the pump shaft, and due to the precision machining to ensure that the impeller and other parts of the concentricity, the pump will not produce metal contact and friction . At the same time, no damage to the pump can occur even if the liquid being conveyed contains fine impurities. So it can maintain long-term stability. ◆ self-priming performance Even non-self-priming pump also has a certain degree of self-priming capability, the pump as long as there is a small amount of raffinate can easily start sending liquid, easy to operate. Nikon high self-priming pump forced exhaust design to make it self-priming capacity of 8 meters. ◆ Cavitation Resistance Air resistance can work well even if air is sucked into the air or the air pocket inside the pump. ◆ Low Noise Due to no metal contact and pressure changes in the pump noise, running noise is very low. ◆ mixing and mixing ability can effectively carry out different liquids or gas and liquid mixture. ◆ Cleanness The contact area of ​​the liquid in the pump is small. After precision machining and special electrolytic grinding, it can be used for ultrapure purposes. ◆ easy to maintain simple structure, fewer parts, not only less fault but also easy to maintain. 2.

Second, the vortex pump and other pump performance comparison 1 compared with the centrifugal pump ☆ small flow high pressure engineering purposes (compared with the single-stage centrifugal pump) pump pressure parts have no mechanical contact and friction, so the stability and durability of special it is good. If you use a larger diameter centrifugal impeller pump, in order to prevent the pressure fluctuations, voids and liquid temperature rise and other phenomena, you have to set the flow to a minimum, to meet the required flow after the bypass pipe bypass with the original Department. This will not only increase the initial investment, high-power motors and increased power consumption, operating costs increased significantly. In contrast, the vortex pump flow pressure is high, when the valve is small, the flow rate decreases, the liquid is also very stable. Therefore, as long as the pump to ensure that not overheating and Motor rated power operation, the flow can be set free, in all aspects can greatly reduce costs. ☆ Filtration Applications (Compared to Multistage Centrifugal Pumps) For high-pressure membrane filtration applications, it is best to use a pump that has no pulsation and maintains a high level of quantitation regardless of its membrane. When a multistage centrifugal pump is used for this purpose, an excessive flow rate may occur when using a new filter membrane. However, when a pump of a proper flow rate is used, the flow rate will be insufficient due to a slight clogging of the filter membrane. Vortex pump flow at the pressure of the open point and the highest point of little change, the most suitable for this purpose. ☆ Harsh Operating Conditions (Compared with Multistage Centrifugal Pumps) Vortex pumps are small in size, simple in construction and have few parts, so they operate freely under harsh conditions requiring high pressure and intermittent operation, water hammer, and repeated negative pressure. In contrast, centrifugal pumps require pressure from multiple stages of impellers and therefore become complex, have large rotational inertia and increase the risk of accidents or malfunctions. ☆ various liquid sampling (compared with self-priming centrifugal pumps) water quality management and various processes need to take a sample solution. UP pump has a strong self-suction, 8 meters away from the liquid can inhale the liquid. And its volume smaller than the centrifugal pump, can quickly drain the residual liquid, greatly reducing the sampling time and ensure the accuracy of sampling. 2. Compared with the gear pump ☆ Pumping from the underground tank to send low pressure liquid vortex pump pressure is best suited for such self-priming performance and high pressure purposes. Not only does it have strong self-priming ability, it also has strong durability even when liquids containing fine foreign particles are transferred because there is no mechanical contact and metal friction in the pump. The gear pump is basically not suitable for low viscosity liquids, often abnormal sound, performance degradation, stuck foreign body and other failures. ☆ High Temperature Waste Oil Spray Combustion Industrial waste, such as used oil or solvent, which has a low viscosity at high temperature, needs to be spray-incinerated. However, this allows the liquid to be easily vaporized at a high temperature, and due to the liquid containing a small amount of foreign matter, the use of a gear pump causes premature performance degradation, foreign matter entrapment, and noise. Under the same conditions, the vortex pump has long service life, low noise and reliable performance because of its low NPSH structure and no metal contact and friction in the pump. 3. Compared with piston pump ☆ High-precision, high-pressure test purposes Low-noise, pulse-free, vibration-free vortex pump is an indispensable pressure source in the development and performance testing of valves, nozzles, automatic control equipment and so on. And it booster department has no mechanical contact and friction, durability, do not need regular replacement parts. The plunger pump, even if the assembly of a large pressure accumulator can not completely eliminate the pulsation, can not guarantee accurate testing and testing, and in the maintenance of a waste of time and money.
