With the development of microcontrollers and the maturity of measurement and protection technology, the application of traditional pumps in production automation and buildings has gradually shifted from the button indicator to an all-in-one intelligent controller (also known as universal pump control Device). In particular, all-in-one intelligent controllers are favored by the market for their functional requirements that meet the needs of information and intelligence. The Shanghai Ning Hong Electric Technology Co., Ltd. as the domestic high-quality industrial products manufacturing professionals in the field of its own R & D and production of universal pump controller in production and living automation applications have been made extremely efficient. NHK-2LP350S intelligent full-voltage start controller new pump controller Overview: NHK-2LP350S intelligent full-voltage start-up controller, is designed to market demand for water pump 0.55-15KW developed a new high-performance products, the main For sewage pump control box, deep well pump control box, regulator pump control box, feed pump control box as an intelligent control supporting the use of modern small pumps to achieve the optimal choice of intelligent control. The new pump controller has the function of a universal machine: First, the control method is universal; by setting the parameters can choose float control, electric contact pressure gauge control, pressure switch control, electrode probe control, electromagnetic probe control, fault pump change control , Rust and other control methods. Second, the power common; By setting the parameters can choose to control the power of 0.55-15KW motor, set the power should be consistent with the actual power of the motor, without adjusting the current (the controller automatically determine the rated current according to the rated power). Third, the common protection functions; By setting the parameters can be short-circuit, phase loss, stalling, overload, no load, dry turn, water, over voltage, under voltage, anti-rust impeller, three-phase unbalanced protection . Advantages of the new pump controller features 1, easy operation, stylish, dual digital dynamic display, indicating full, rich and perfect fault code prompts, so that the general pump room managers without going through complex training, but also on the various Operate freely, without the need for professional engineers to operate it. For installation and commissioning personnel, and telephone communication can handle the general failure, save time and easier to operate. 2, grouped parameter code to facilitate the debugging staff or users to accurately find the required setting parameters. 3, rust function, turn on this feature can be timed to start the inspection of the pump to prevent the pump does not work for a long time cause the pump easy to rust. 4, anti-time protection, the greater the load operating current, the greater the protection time is shorter, the smaller the running current protection time longer. 5, definite time protection function, the use of high-precision primary current transformer, instead of the traditional thermal relay to detect the load current, through the upper and lower current limit set to make its protection action, more accurate than the original motor protection, more stable, more reliable. 6, voice navigation function, through the voice of the entire product fault, operation, alarm voice to explain and enhance the overall grade of the product. At present, Ning Hong Almighty pump controller has been successfully used in Shanghai Panda, Shanghai Aoli, sea lions and other hundreds of pump industry leader in the process of product use.

I. Introduction
Cationic Fixing Agent is polyelectrolyte, consists of a series of organic synthesis with low molecular weight and strong cationic, which is generally 100% cationic. Product character is aqueous solution.
II. Performance Indicators:
1. Appearance: colorless to pale yellow viscous liquid
2. Solid content: ≥ 50%
3. PH: 2 ~ 6
4. Viscosity: 50 ~ 200 mpa.s
III. Application Field
Used in paper pulp as a cationic fixing agent. Usually the slurry contains colloidal particles consisted of fiber materials, additives and water, which are with anionic charge and interfere the papermaking process, so it is also known as anionic trash; the interference is mainly in the following aspects:
1. Influence wet chemical additives` normal function, especially for cationic retention and drainage aids, sizing agent; or cause to increase the amount of wet chemical additives;
2. Deposits in the paper machine system; interfere the efficient papermaking process.
3. COD discharge of sewage systems, increasing the load on the sewage treatment plant. Recommended for use in mechanical pulp, chemi-mechanical pulp, and secondary fiber pulp slurry and coating waste stuff. Anionic trash neutralized by fixing agent can be bonded to the fibers so as to be taken away by paper sheets.
IV. Methods of Application
Adding methods: excellent water-solubility; can spread out in water instantly. Dosing pump is generally used to drive it into a static mixer or a mixing pump , mixed with water, diluted to about 0.2% of the dissolved solution, and then into the slurry system.
Adding point: the general adding point is in the front of flow system, that is, before the machine chest or fan pump; or add in the pulp plant. Which is taken into consideration for the reaction time of the cationic fixing agent polymer molecules and garbage, also need to time and space for other wet end additives. According to the slurry source, sometimes you need to select two or more points to add. When the slurry contains a source of coated broke, generally requires additional anionic trash Fixative in the transport of the paper sheet.
Adding dosage: anionic trash content in the slurry is usually gauged by the cationic charge contents measured by PCD (particle charge analyzer) in the slurry. The measure will directly show the dosage tips, but the real dosage depends on the practical application. For general slurry, the recommend amount is in the range of 0.3kg ~1.8kg/t dry pulp.
V. Safe Operation
1. Cationic fixing agent is a water-soluble polymer, dissolved in water in a highly slippery state and avoid to spill on the floor. If spill, shall timely absorb with sand, sawdust.
2. Wear gloves, wear overalls to operate.
VI. Storage
The product should be kept sealed, stored in cool, dry, ventilated places, and appropriate temperature should be 10-30 ℃.
VII. Package
200 kg plastic drums or 1000 kg PE IBC drum.
