Fluoroplastic centrifugal pump has many advantages. It is divided into two main centrifugal pumps: IHF centrifugal pump and FSB centrifugal pump. They are mainly used for durability, convenience and high efficiency. It has strong corrosion resistance, high mechanical strength, no aging, non-toxic and non-decomposition. It has the advantages of wide performance parameters, high efficiency, compact structure, simple maintenance, energy saving, etc., avoiding running, running, dripping and leaking in production. Fluoroplastic centrifugal pump design features 1. Based on the design of the traditional corrosion-resistant magnetic pump, the structure of the parts is optimized and the magnetic eddy current is eliminated. Strong magnetic torque makes the product efficient and energy-saving. 2. The IMD magnetic pump adopts a back-pull structure, which can easily carry out internal maintenance and parts replacement without dismantling the pipeline, which is convenient for daily maintenance and maintenance work. 3. IMD-F magnetic pump isolation sleeve is made of polyetheretherketone filled carbon fiber, which has high-strength chemical function, no magnetic loss and high pressure. In case of contact between the outer magnet and the isolation sleeve, there will be no sparks to ensure safe use. Fluoroplastic centrifugal pump product advantages 1. Two compression molding methods are used for lining and high temperature annealing process, which can fully release the internal stress of the lining plastic and avoid cracking. At the same time, the lining plastic and the metal surface are more closely attached, even if working in a high temperature environment, the lining layer is still firm and stable (the all-plastic shell is made of fluorine alloy, so this process is not required). 2. The magnetic rotor in the magnetic pump uses computer-controlled magnetization technology, which is divided into two types: strong magnetic and weak magnetic. The configuration of the weak magnetic rotor has certain advantages in price, and is suitable for low flow, low power conditions or conditions with low technical requirements (such as: college laboratories, etc.). 3. The internal and external magnets of each fluoroplastic magnetic pump have been tested and corrected for dynamic balance to ensure the accurate precision of the magnetic pump equipment. 4. Like the inner magnet, the outer magnet of the fluorine plastic magnetic pump is divided into weak ferrite and high-grade strong magnet NdFeB. Magnetic pumps equipped with ferrite magnets have certain advantages in price and are suitable for working conditions with low technical requirements. 5. Equipped with PEEK (polyetheretherketone) reinforced sleeve, although the PPS (polyphenylene sulfide) reinforced sleeve has high mechanical strength, high temperature resistance, and chemical resistance, the PEEK (polyetheretherketone) reinforced sleeve is obviously better. The pressure resistance of ordinary PPS reinforcement sleeve is only 1.6Mpa, and the pressure resistance of PEEK reinforcement sleeve can reach 3Mpa. Generally used in high-end machinery, nuclear engineering and aviation and other technologies. 6. For the fluoroplastic magnetic pump anti-abrasive parts, there are various material configurations to meet the requirements of different working conditions. Customers can consult our company in detail. 7. Equipped with YE3 high-efficiency energy-saving motor with secondary energy consumption, the power consumption is ultra-low. Although the price is slightly more expensive than the YX3 motor, the daily energy saving can reach 3%-8%. 2BE1 Series Liquid Ring Vacuum Pump

(1) Motor reverse Due to wiring, the steering of the motor will be opposite to the actual required steering of the centrifugal pump. Generally, observe the steering of the pump when starting. If the steering direction is opposite, replace any two wires on the motor terminal. (2) The working point moves to high flow and low head Generally speaking, the centrifugal pump has a continuous downward performance curve, and the flow increases gradually with the decrease of head. During operation, due to some reason, the back pressure of the pump decreases, and the working point of the pump passively moves to the low head point flow with the curve of the device, which will lead to the reduction of head. In fact, this is caused by external factors such as changes in equipment, which has no special relationship with the pump itself. At this time, as long as the back pressure of the pump increases, such as closing the outlet valve a little. The problem can be solved. (3) Slow down The important factors affecting the pump head of centrifugal pump are impeller outer diameter and pump speed. When other conditions remain unchanged, the pump head is directly proportional to the quadratic power of speed. It can be seen that the speed has a great influence on the pump head. Sometimes, if the speed of the pump is reduced due to some external reason, the pump head will be reduced accordingly. At this time, check the speed of the pump. If the speed is not enough, check the cause and solve it reasonably. (4) Cavitation at inlet If the suction pressure of the centrifugal pump is too low and lower than the saturated vapor pressure of the pumped medium, cavitation will be formed. At this time, check whether the inlet pipeline system is blocked, or whether the opening of the inlet valve is too small, or raise the liquid level of the suction tank. (5) Internal leakage When the gap between the rotating part and the stationary part of the centrifugal pump exceeds the design range, internal leakage will occur, which is reflected in the decrease of the discharge pressure of the pump, such as the gap between the impeller port ring and the interstage gap of multi-stage pump. At this time, corresponding disassembly and inspection shall be carried out to repair or replace the parts causing excessive clearance. (6) Impeller passage blocked If part of the flow passage of the impeller is blocked, the operation of the impeller will be affected and the outlet pressure will drop. Therefore, it is necessary to disassemble the pump to check and remove foreign matters. In order to prevent this problem from happening again, if necessary, a filtering device can be added in front of the inlet of the centrifugal pump.
