Generally speaking, it is not necessary to install a bottom valve because corrosion-resistant pumps usually have their own check valves at the inlet. After the corrosion-resistant self-priming pump is shut down, the liquid in the pump chamber cannot flow back to the original pool and is stored in the pump chamber. Therefore, there is no need to add liquid during the second use. However, it does not mean that the corrosion-resistant self-priming pump cannot be equipped with a bottom valve. Installing a bottom valve will improve the effect, because if the one-way valve is sometimes damaged, the bottom valve will serve as a guarantee and will not idle after installation. If a bottom valve is installed, the effect will be better, because if the one-way valve is sometimes damaged, the bottom valve serves as a guarantee and will not idle. After installing the bottom valve, it will also effectively ensure the effective suction range of the pump. Another special case, but if the difference in suction height is too large, or the diameter of the suction pipe is too large, and the volume exceeds the storage capacity of the corrosion-resistant self-priming pump chamber, it cannot work normally. At this point, a bottom valve must be installed to ensure safe and fast self- priming. Therefore, the self-priming pump does not require the installation of a bottom valve, but it does not mean that the bottom valve cannot be installed. After the installation of the bottom valve, the suction range of the pump will be more guaranteed, especially for some small corrosion-resistant self-priming pumps. Due to the fact that small corrosion-resistant self-priming pumps generally do not have one-way valves and achieve self-priming effect through the vacuum generated by the instantaneous pump body, the suction effect of the pump will be better after the bottom valve is installed.

Medium viscosity: 1-1500mm2/s Pump pressure range: 4.0MPa Flow range: 1-2000m3/h Temperature range: -15 to 280 degrees Celsius Pumps can transport media such as lubricating oil, hydraulic oil, cutting oil, cooling oil, wax, tar, light oil, liquefied petroleum gas, crude oil, heavy oil, and asphalt. Oil and gas Twin screw pumps are ideal pumps for transporting crude oil, natural gas, water, and solid mixtures. They can be used on land and at sea. The pump can operate dry and transport media containing gas. Its compact design and special thread profile ensure long-distance pipeline transportation. Application of multiphase crude oil transportation, thermal power plants, and crude oil storage. ocean Twin screw pumps can be used on oil tankers for loading and transportation, lubricating the main engine, and transporting tar, asphalt, light and heavy fuel oils, crude oil, and chemicals. Petrochemical industry, refinery This pump can transport low viscosity liquids, including media with neutral, alkaline, acidic, or gaseous or abrasive materials Applied to heavy oil, asphalt, tar, heavy fuels, naphtha, and chemical products chemical industry Whether low viscosity or high viscosity, it can transport various liquids with corrosiveness and solid particles, Pumps are used for transporting polymers, coatings, slurries, liquid sulfur, or chemicals. 1、 Fluid characteristics of mixed naphtha Blended naphtha refers to a mixture of naphtha and a certain proportion of light hydrocarbons. Due to the addition of light hydrocarbons, the fluid characteristics of mixed naphtha are more complex than those of pure naphtha. Specifically, blended naphtha has the characteristics of high viscosity and high specific gravity, and the viscosity decreases with increasing temperature, which poses certain difficulties in pump selection. 2、 Characteristics of screw pumps and centrifugal pumps 1. Screw pump Screw pump, also known as rotary thruster, works by pushing liquid into the pipeline through the rotation of the screw. The main characteristics of screw pumps are strong adsorption capacity and pressure stability, and the ability to transport high viscosity liquids. 2. Centrifugal pump A centrifugal pump refers to a type of pump that uses centrifugal force to push liquid into a centrifugal casing, and then discharges it through an outlet pipe. The main characteristics of centrifugal pumps are high flow rate and stable pressure, but they are prone to blockage when transporting high viscosity liquids. 3、 Choose the appropriate pump Due to the fluid characteristics of blended naphtha itself, when selecting a pump, it is necessary to consider both flow rate and pressure stability, as well as adaptability to high viscosity liquids. In this case, screw pumps are more suitable for transporting mixed naphtha. The adsorption capacity and pressure stability of screw pumps can effectively solve the problem of transporting high viscosity liquids. In addition, the repair and maintenance costs of screw pumps are relatively low, and their reliability is high. Although centrifugal pumps have advantages in terms of flow rate, they are prone to blockage and overload when transporting high viscosity mixed naphtha, which can cause unnecessary problems during operation

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
