Canned motor pump is composed of a shielded electric motor and a pump. It is a power equipment used for conveying fluids. The equipment is mainly composed of pump body, impeller, stator, rotor, front and rear bearings, thrust disc and other components. The stator and rotor are separated by non-magnetic corrosion-resistant thin-walled sleeves, and the rotor is supported by front and rear bearings immersed in the conveying medium, so no type of dynamic seal is required to prevent the outward leakage of the conveyed medium. Overall, shielded pumps are centrifugal unsealed pumps. Shielded pumps are absolutely leak free, and under negative pressure inside the pump, external gases will not be sucked in, making them particularly suitable for vacuum system operation; At the same time, it is suitable for high pressure, high melting point, and high and low temperature media. Shielded pump has a compact structure, small volume, and light weight; No cooling fan, low noise, wide range of use, reliable operation, can provide a relatively good working environment. A typical shielded pump uses a portion of the conveyed liquid to cool the motor, and the annular gap is very small, so the conveyed liquid must be clean. When transporting multiple liquid mixtures, if they produce precipitation, coking, or gel like substances, using a shielded pump (non mud type) at this time may block the shielding gap, affect the cooling and lubrication of the pump, and lead to burning of graphite bearings and motors. Shielded pumps generally have circulating cooling pipes. When the ambient temperature is below the freezing point of the pumped liquid, anti freezing measures such as accompanying pipes should be taken to ensure easy pump start-up. In addition, when starting the shielded pump, the opening sequence of the outlet valve and the inlet valve should be strictly followed. When stopping the pump, the outlet valve should be closed first. After the pump stops running, the inlet valve should be closed first and then the outlet valve should be closed. In short, by using a shielded pump, there is no leakage at all, effectively avoiding environmental pollution and material loss. As long as the selection is correct and the operating conditions do not change abnormally, there is almost no maintenance workload under normal operation. Shielded pumps are ideal pumps for transporting flammable, explosive, corrosive, and valuable liquids According to the temperature, pressure, viscosity, and presence of particles of the transported liquid, shielded pumps can be divided into the following types. The temperature of the basic conveying medium shall not exceed 120 ° C, and the head shall not exceed 150m. Various other types of shielded pumps can be obtained by modifying and improving the basic model. In this type of shielded pump, the direction of liquid flow for bearing lubrication, cooling, and motor cooling is exactly opposite to that of the basic type. Its main feature is that it is not prone to cavitation and is particularly suitable for the transportation of easily vaporized liquids, such as liquefied petroleum gas, chloromethane, etc. High temperature type generally transports media with a maximum temperature of 350 ° C, a maximum flow rate of 300m3/h, and a maximum head of 115m, suitable for high-temperature liquids such as oil and hot water. High melting point pumps and motors with jackets can significantly improve the heat resistance of the motor. Suitable for high melting point liquids, with a maximum temperature of 250 ° C. The jacket can be filled with steam or liquid at a certain temperature to prevent crystallization of high melting point liquids. The casing of a high-pressure shielded pump is a high-pressure vessel, which enables multi-stage pipeline pumps to withstand high system pressures. To support the shielding sleeve under high internal pressure, the stator coil can be used to withstand pressure. When the self-priming suction tube is not filled with liquid, the pump discharges the liquid through automatic pumping, which is suitable for extracting liquid from underground containers. The multi-stage type is equipped with multiple impellers, suitable for high head fluid transportation, with a maximum head of up to 400m. Mud type is suitable for transporting liquids mixed with large amounts of mud

TLRP stainless steel rotary pump relies on two synchronously counter rotating rotors to generate suction (vacuum degree) at the inlet during the rotation process, thereby sucking in the material to be conveyed. Two rotors separate the rotor chamber into several small spaces and operate in the order of ABCD; When operating to position A, only chamber I is filled with medium; When reaching position B, a portion of the medium is enclosed in chamber B; When reaching position C, a portion of the medium was also enclosed in room A; When reaching position D, chambers A and B are connected to chamber II, and the medium is transported to the discharge port. Selection of transmission driver/motor 1 - Motor with fixed ratio reducer: This transmission method is simple, with a constant rotor speed, which determines the non adjustability of the flow rate. 2 - Motor with mechanical friction type continuously variable transmission: This type of transmission is achieved through manual adjustment, characterized by safety and reliability, high torque, and infinitely adjustable flow rate. The disadvantage is non automatic adjustment, which is more complicated. The speed regulation is carried out during operation and cannot be adjusted while the machine is stopped. Its use and maintenance should refer to the manufacturer's user manual. 3 - Variable frequency motor with frequency converter: This method can achieve automatic adjustment of speed, that is, infinite adjustment of flow rate. Its advantages are high degree of automation and large low-speed torque. The disadvantage is that the price of the frequency converter is relatively high. Refer to the manufacturer's user manual for its use and maintenance. Feature: 1 - Maintain a certain gap between rotors and between rotors and pump bodies, with no friction coefficient and long service life. 2 - Easy to assemble and disassemble, convenient to maintain and clean, with few vulnerable parts. 3 - Effective energy saving, low failure rate, reliable sealing, and low noise. 4 - After using special materials, it can transport media containing solid particles such as sludge and sewage. 5 - The transportable medium has a viscosity of is no more than 2 million cp and a slurry with a solid content of 60 percent. 6 - After configuring the transformer, the flow rate can be adjusted freely and it can be used as a general metering pump. 7 - According to user connection requirements, flange type, screw type, and clamp type can be selected. 8 - Can transport mixed materials of air, liquid, and solid phases. 9 - The insulation cooling pump adopts a built-in structure with good thermal conductivity. 10 - The mobile pump can suction various barrel materials, with a suction vacuum degree of 0.08Mpa 11 - According to user requirements, a sanitary safety valve can be installed on the pump head.
