The working principle and application of self-priming magnetic drive pump

The pump uses static seals instead of dynamic seals, so that the flow parts of the pump are in a completely sealed state, which solves the problems of running, emitting, dripping and leaking that cannot be avoided by other pump mechanical seals. The materials of the pump body and flow parts are all adopted. Made of corrosion-resistant stainless steel, corundum ceramics, tetrafluorographite and other materials.

The pump not only has the function of a magnetic drive pump, but also integrates self-priming. It does not need a bottom valve and irrigation water. The self-priming height is 4m. It can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research and other units to pump acid. , Alkali, oil and rare precious liquids, venoms, volatile liquids, and circulating water equipment, especially for the pumping of leaky, flammable, and explosive liquids.

The fluoroplastic self-priming magnetic drive pump adopts a direct-connected motor structure and is supported by a middle bracket. The inner and outer magnets are made of high-performance magnetic material “neodymium iron boron”. The isolating sleeve is used to eliminate the magnetic eddy current loss of general magnetic drive pumps. The liquid part of the pump is Fluoroplastic, but the outer shell is made of metal material, so the pump body can bear the weight of the pipeline and withstand mechanical shocks.

　The working principle of the self-priming magnetic pump: The pump adopts an external-mixed axial return water pump body structure. The pump body is composed of a liquid suction chamber, a liquid storage chamber, a volute, a return hole, a gas-liquid separation chamber, etc. The structure is shown in the schematic diagram. After the pump is started, under the action of centrifugal force, the remaining liquid in the suction chamber and the air in the liquid inlet pipe are stirred by the impeller to form a water-gas mixture. The mixture enters the gas-liquid separation chamber through the volute. The water is separated, and the air is discharged from the outlet of the pump, and the liquid returns to the pump through the return hole. After multiple cycles, the air in the inlet pipe is drained, so that a certain degree of vacuum is formed in the pump to achieve self-priming. The protector for the pump can be configured to automatically cut off the power when the pump is idling or overloaded, so as to protect the internal components of the pump or the motor from being damaged due to the idling of the pump or the overload of the motor. Applicable temperature: -30℃～200℃

Purpose of self-priming magnetic drive pump: The pump has compact structure, beautiful appearance, small size, low noise, low noise, reliable operation, convenient use and maintenance, and can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, and scientific research. Units such as pumping acids, alkalis, oils and rare precious liquids, venoms, volatile liquids, as well as supporting equipment for circulating water, especially the pumping of leaky, flammable, and explosive liquids.

What is the difference between a centrifugal pump and a self-priming pump?

Should you choose a centrifugal pump or a self-priming pump? I must have a certain understanding of centrifugal pumps and self-priming pumps. In simple terms, compared with self-priming pumps, self-priming pumps have a certain self-priming ability. The pump does not. In normal operation, the self-priming pump has a suction stroke of 6-8 meters. The centrifugal pump has no suction stroke. Only when the bottom valve is installed, it has a certain self-priming ability. SAIKEN below is for you Detailed introduction

The specific difference between centrifugal pump and self-priming pump is as follows:

The composition is different: the self-priming pump is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber, etc.; the basic structure of a centrifugal pump is composed of six parts: the impeller and the pump body , Pump shaft, bearing, sealing ring, stuffing box.
Different advantages: the self-priming pump is simple to operate, stable in operation, convenient to maintain, high in efficiency, long life, and self-priming; the centrifugal pump has a wide flow range and a wide lift range, which can be applied to certain corrosive liquids. Shock absorption, low vibration, simple and convenient equipment installation. 　　3. The working principle is different: the centrifugal pump works by the centrifugal movement of the water due to the rotation of the impeller; the working principle of the self-priming pump is that the pump casing is filled with water before the pump is started (or the pump casing itself contains water). After starting, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, so that the water inlet check door opens, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.

Selection of corrosion-resistant centrifugal pump?

The selection of corrosion-resistant centrifugal pumps needs to understand the following principles:

　　1. The characteristics of the medium: the type of the medium, its proportion, the ph value, whether it is toxic, the particle diameter and the content of the medium, and the temperature of the medium.

　　 2. Leakage of corrosion-resistant centrifugal pump. What is the normal working flow rate of the general corrosion-resistant centrifugal pump? The amount of water leaked from the piping system in the normal industrial production process of the corrosion-resistant centrifugal pump is almost negligible, but the changes in leakage caused by process changes need to be considered. If corrosion-resistant centrifugal pumps are used for open channel drainage in agriculture, the amount of permeation and evaporation are also indexes to be considered.

3. Pressure. The pressure of the drain pool, the pressure of the suction pool　4. The diameter of the pipe, the total length of the pipe, the type and number of accessories of the pipe, etc.

5. Material. Corrosion-resistant centrifugal pumps are made of non-corrosion-resistant ductile iron and carbon steel, as well as corrosion-resistant stainless steel, and high-temperature alloy steel.

The form of sealing. Outer seal: including packing seal, mechanical seal, floating ring seal, labyrinth seal box spiral seal. Inner seal: general seal ring, also called mouth ring and clamp ring 　　
Choose the appropriate pump according to the flow and head required by the working environment. 　　
The form is determined according to the conditions of the installation site of the corrosion-resistant centrifugal pump, the vertical, horizontal and transmission forms of the corrosion-resistant centrifugal pump. 　　
Another important factor for corrosion-resistant centrifugal pumps is driving force. According to different power sources, choose corrosion-resistant centrifugal pumps with different driving forces. 　　
Choose the structure of the corrosion-resistant centrifugal pump according to the actual situation of the site. The corrosion-resistant centrifugal pump is divided into a clean water pump, a sewage pump, and a mud pump.

　　 Four: Selection of commonly used materials for concentrated sulfuric acid magnetic pump

60% concentration (normal temperature, high temperature) uses PP material, 98% concentration (normal temperature) uses PVDF material as one of the strong corrosive media. The corrosion of sulfuric acid with different concentrations and temperatures is quite different. For the concentration above 80%, the temperature Concentrated sulfuric acid less than 80, engineering plastics have better sulfuric acid resistance, and engineering plastic pumps are a more economical choice. For high-temperature sulfuric acid media, fluoroplastics or stainless steel are mostly used.

What should I pay attention to when using acid and alkali resistant magnetic drive pump?

Acid and alkali resistant magnetic drive pump is a new type of pump that uses the working principle of magnetic coupling to transmit torque without contact. When the motor drives the outer magnetic rotor to rotate, the magnetic field drives the inner magnetic rotor and the impeller to rotate synchronously, so as to achieve For the purpose of pumping liquid, since the liquid is enclosed in a stationary isolating sleeve, it is a fully sealed, leak-free pump type.

Pay attention to the following points when using acid and alkali resistant magnetic drive pump:

　　 1. Acid and alkali resistant magnetic pump should be checked at regular intervals (about 1000h). The insulation resistance of the acid and alkali resistant magnetic pump should be not less than 0.5MΩ. If it does not meet the requirements, it should be dried.

　　2. Before use, check the cables, switches, and electric shock protectors. The switches and other electrical appliances should work normally, the cables are not damaged, and the cables should be carefully identified. The yellow and green two-color wires are grounding wires to prevent leakage and electric shock accidents.

　　 3. When the acid and alkali resistant magnetic pump enters or discharges water, the power must be cut off, and then the rope tied to the hoisting ring must be pulled. The cable cannot be used as a pull rope.

4.The acid and alkali resistant magnetic pump cannot be buried in the river mud. If there are many water and leather debris in the water, the acid and alkali resistant magnetic pump should be placed in the basket or basket, and then the basket or basket should be placed in the water.

　　 5. When the acid and alkali resistant magnetic pump is tested outside the water (such as to determine the direction of rotation), it shall not exceed 1 minute to prevent the motor from heating and burning.

Fluoroplastic magnetic pump manufacturers and suppliers

What are the advantages of fluoroplastic chemical magnetic pump?

Fluoroplastic chemical magnetic pump is a branch of the magnetic pump field, and is a new product that applies the working principle of permanent magnet coupling to centrifugal pumps.

　　 PP chemical magnetic pump is composed of three parts: pump, magnetic drive and motor. The magnetic drive of the fluoroplastic chemical magnetic pump consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. The working principle of the magnetic pump is that when the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, and drive the inner magnetic rotor connected to the impeller to rotate synchronously, realize the non-contact and synchronous transmission of power, and will easily leak the power. The sealing structure is transformed into a static sealing structure with zero leakage.

　　The advantages of fluoroplastic chemical magnetic pump are:

　　 1. Good sealing effect, as long as the isolating sleeve is not damaged, there will be no leakage.

　　2. The motor has a strong anti-overload capability. Because it is a magnetic drive, the inner shaft will not cause the motor’s outer shaft to jam.

　　3. It can be better applied to the transportation of flammable, explosive, toxic, harmful and corrosive media.

　　 4. Easy to disassemble.
