Overview
Magnetic drive centrifugal pump (hereinafter referred to as magnetic pump) is the application of modern magnetism principle, the use of permanent magnet magnetic torque transmission to achieve a new type of non-contact transmission, that is, the motor driven outer rotor (outer magnet) assembly rotation , Through the role of the magnetic field lines through the isolator to drive the inner rotor (ie, the inner magnet) assembly and the impeller rotating synchronously, as the media enclosed in a quiescent isolation sleeve, so as to achieve the purpose of leak-free pumping medium, completely solve the mechanical transmission Pump shaft seal leaks, and the design of a fully sealed, leak-proof, non-polluting new industrial pumps.
Magnetic pump is a chemical process to eliminate running, running, dripping, leakage phenomenon, eliminate environmental pollution, and create a "leak-proof workshop", "leak-free factory" to achieve safe and civilized production of the ideal pump. Widely used in petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection and other enterprises in the delivery of non-ferrous scrap corrosive liquids, especially for flammable, explosive, volatile, toxic and valuable liquid delivery.
In the field of petrochemicals, more and more manufacturers require a leak-free process environment for their media. In some special cases, such as transporting hot oil or granular media (such as sewage treatment), and chemical production The process, the more urgent need to choose the ideal leak-free pump. On the basis of producing CQ type magnetic pump, our company introduced domestic and foreign new technologies, developed MT-HTP series magnetic transmission high temperature chemical process pump, MT-MSP series magnetic drive high temperature multistage pump and suspension separator Magnetic pump products to solve the conventional magnetic pump has been unable to solve the delivery of high temperature (350 ℃) and with granular media technical problems, can directly replace the mechanical transmission of the IH chemical pump. MT series of magnetic pumps after long-term productive continuous operation test, the user can be sure that they are using the most safest and most reliable pump.
Transmission principle
Magnetic pump is the use of magnetic coupling principle of non-contact torque transmission torque of a new pump, when the motor drives the outer rotor rotates, the role of the magnetic field driven by the magnetic rotor and the impeller rotation in synchronism, so as to achieve the pumping of liquid For the purpose, it is a hermetically sealed, leak-free pump since the liquid is enclosed in a stationary isolation sleeve.
Pump features
Removed the mechanical seal pump, mechanical seal completely eliminate the pump inevitable run, run, drip, leakage of the shortcomings of the plant is the best choice for leaks.
As the pump flow components selected stainless steel, engineering plastics to manufacture, so as to achieve the purpose of corrosion resistance.
Pump magnetic coupling and pump body as a whole, so compact, easy maintenance, safety and energy saving.
Pump magnetic coupling can drive motor overload protection.
The purpose of the pump
Magnetic pump with its full seal, no leakage, corrosion-resistant features, widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, defense and other departments for pumping flammable, explosive, toxic and valuable liquid , Is to create a leak-free, non-polluting civilized workshops, civilized factories ideal pump.
Working conditions
Magnetic fluid pump medium density of not more than 1300kg / m3, the viscosity of not more than 30 × 10-6m3 / S of non-ferromagnetic and fiber-containing liquid. Conventional magnetic pump rated temperature for the pump body made of metal or F46 lining, the maximum operating temperature of 80 ℃, rated pressure of 1.6MPa; high temperature magnetic pump temperature ≤ 350 ℃; for the pump body is non-metallic, the maximum temperature is not Over 60 ℃, rated pressure of 0.6MPa.
For the transmission medium density greater than 1600kg / m3 of liquid, magnetic couplings need to be designed.
Magnetic pump bearings are transported by the lubrication medium cooling, drum magnetic pump is strictly prohibited no-load operation.

Rice Cooker
A rice cooker or rice steamer is an automated kitchen appliance designed to boil or steam rice. It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex rice cookers may have many more sensors and other components, and may be multipurpose. Cooking rice has traditionally required constant attention to ensure the rice was cooked properly, and not burnt. Electric rice cookers automate the process by mechanically or electronically controlling heat and timing, thus freeing up a heating element on the cooking range that had to be otherwise occupied for rice cooking. Although the rice cooker does not necessarily speed up the cooking process, with an electric rice cooker the cook's involvement in cooking rice is reduced to simply measuring the rice, preparing the rice properly and using the correct amount of water. Once the rice cooker is set to cook, the rice will be cooked with no further attention.
Features:
For modern home rice cookers, the smallest single-person model cooks 1 rice cup (180 ml), whereas large models can cook 10 cups. Commercial models can cook 20 or more cups. As a possible source of confusion, model specifications and names may list either cooked or uncooked capacity. Rice roughly doubles in size during cooking; therefore, a 10 cup (uncooked) rice cooker can produce up to 20 cups of cooked rice. The prices vary greatly, depending on the capacity, features, materials used, and the country of origin.
The majority of modern electric rice cookers are equipped with a stay-warm or keep-warm feature, which keeps the rice at an optimal temperature for serving without over-cooking it. Some gas cookers also have electric stay-warm mechanism. However, the usefulness of this feature degrades over time, a microwave may be more energy efficient or better suited to reheat rice that will sit longer than four hours.
Some rice cookers use induction heating, with one or more induction heaters directly warming the pot. This can improve energy efficiency.
Most modern rice cookers use aluminium for the inner cooking bowl. There are some models that use stainless steel instead of aluminium. Various other materials, such as copper, pure carbon, ceramic, and diamond powder coating, may be used for higher heat conductivity or better taste.
The pressure-cooking models can raise the water's boiling point higher, e.g., from 100 °C at 1.0 atm up to about 110 °C at 1.4 atm, which speeds cooking. The pressure-cooking models can also be used in high altitude areas, where the boiling temperature is below 100 Celsius. Pressure cookers are also suitable for cooking brown rice (which contains oils and bran fiber that cook differently from pure white rice starch). Some pressure rice cookers have a varying pressure control mechanism (named the "dual-pressure" method) that creates repeated pressure/release cycles during the cooking.
There also exist mechanisms to collect and return the boiled over liquid to the inner rice bowl.
Many cookers now have microprocessor-controlled cooking cycles, which are often used to adjust for rice and cooking type.
Applications
Rice cookers are typically used for the preparation of plain or lightly seasoned rice. Each rice cooker model may be optimized to cook a certain type of rice best. For example, most Japanese rice cookers are optimized for cooking Japanese rice and may not be the best for other types of rice[citation needed], although cooking time can be lengthened simply by more water.
The typical method of cooking long grain rice is boil-and-strain and/or steaming method. The absorption method used in Japanese rice cookers will produce slightly different texture and taste, usually stickier rice.
Brown rice generally needs longer cooking times than white rice, unless it is broken or flourblasted (which perforates the bran).
Different varieties of rice need different cooking times, depending on their grain size, grain shape, and grain composition. There are three main types of Asian rice: Oryza sativa subsp. indica, i.e., Indian rice (long grain rice, e.g., basmati rice and Thai jasmine rice), O. sativa subsp. javanica, i.e., Java rice (large grain rice) and O. sativa subsp. japonica, i.e., Japanese rice (medium grain rice, e.g., Calrose rice, short grain rice, e.g., most Japanese rice and risotto rice).
African rice, Oryza glaberrima, is an entirely separate species, but can be cooked in the same way. Zizania is not even in the same genus, although it is often called a rice (or "water oats"); it, too, can also be cooked in a rice cooker.
A rice cooker can be used to cook many boiled or steamed granular foods, such as pot barley, bulgar wheat, and dal. Provided the ingredients have similar cooking times, a rice cooker can cook mixtures such as khichdi. Some rice cookers can be used as automated couscoussiers, cooking couscous and a stew simultaneously.
