  How to extend the service life of the sewage pump?

  It is forbidden to start the machine with abnormal power supply voltage. Since the low-voltage power supply line is relatively long, it is common for the voltage at the end of the line to be too low. When the phase voltage is lower than 198 volts and the line voltage is lower than 342 volts, the speed of the sewage pump motor decreases. When it does not reach 70% of the rated speed, the starting centrifugal switch will be closed, causing the starting winding to be energized for a long time and heat up or even burn the winding and capacitor. On the contrary, excessive voltage causes the motor to overheat and burn the winding. Therefore, when the sewage pump is in operation, the operator must observe the power supply voltage value at any time. If it is lower than the rated voltage by less than 10% and higher than the rated voltage by more than 10%, the motor should be stopped to find out the cause and troubleshoot.   Confirm the correct direction of rotation of the motor. The direction of rotation of the motor should be clear. Now there are many types of sewage pumps that can discharge...

  Why is the submersible pump not pumping water due to too high current?

  Submersible pumps are easy to use and have low installation costs, and are widely welcomed by users. Although submersible pumps are easy to use, they often have operating problems. What is the reason why the submersible pump current is too high and does not supply water? (I) Cut off the power supply and pull the submersible pump out of the water to the shore. Check whether the impeller is entangled or stuck by foreign objects. The motor cannot rotate and the current increases, causing heat. (ii) If there is no foreign matter entangled, check whether the impeller rotates smoothly. (It is impossible for the impeller of a submersible pump to rotate multiple times as smoothly as a general motor by adding force. The submersible pump can rotate as long as the seal is tight. (iii) If it cannot rotate even after being rotated, it is likely that the rotor bearing is damaged. If the motor rotor is swept, the bearing should be replaced, and both bearings should be replaced at the same time. (iv) Open the junction box to check whether the three motor lead wires are firmly pressed, and then use the multimeter ohm RX1 gear to measure whether...

  In what industries can multistage centrifugal pipeline pumps be used?

  What industries can multistage centrifugal pipeline pumps be applied to? Multistage centrifugal pipeline pumps are a commonly used industrial equipment for conveying liquids or gases. It transports fluids from one place to another by centrifugal force. Multistage centrifugal pipeline pumps usually consist of multiple centrifugal stages, each of which contains a centrifugal rotor and a guide vane. The following is an introduction to the uses of multistage centrifugal pipeline pumps. Industrial use: Multistage centrifugal pipeline pumps are widely used in the industrial field to transport various liquids and gases, such as clean water, wastewater, petroleum, chemical liquids, etc. They can be used in the fields of petrochemicals, pharmaceuticals, food processing, energy, etc. to transport raw materials, products and waste. Water treatment: Multistage centrifugal pipeline pumps play an important role in water treatment systems. They can be used for processes such as water supply, water pressure, drainage and sewage treatment. For example, in urban water supply systems, they are able to transport water from the water source to the water treatment plant, and then distribute the treated water to various users. Construction industry: Multistage centrifugal pipeline pumps are also widely used in the construction industry. They can be used to supply...

  Blowdown pump produces the harm of cavitation

  Shandong Hairui Zhonglian Pump Industry Co. , ltd. The blowdown pump that is a major produces manufacturer. When type selecting of client blowdown pump, manufacturer of my company water pump can provide the before-sales service such as price of pump of blowdown pump model, blowdown, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge that produces cavitation harm about blowdown pump: What is cavitation? The liquid local pressure in pump drops when critical pressure, bubble can generate in the liquid. Cavitation is bleb gathers, the motion, dissension, whole process that kill. Critical pressure is close to vapour pressure commonly. What harm does cavitation have? A, shed a component to corrode tooCorrode a reason to have two: Because bleb is undone,be when generation is high frequency (600~25000HZ) concussion, pressure is as high as 49Mpa, cause metallic surface occurrence machinery to denude; 2 because quantity of heat is emited when vaporization,be, thermoelectricity pool action produces hydrolysis, the oxygen of generation makes the metal oxidizes, produce chemistry to corrode. B, Blowdown pumpFunction dropsDisturb and the energy exchange inside the impeller when...
