VilniusISG single stage vertical pipeline pumpHow to buy cost-effective

　　A large amount of lubricating oil is stored.　　After that the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.Vilnius,VilniusRubber lining submerged slurry pump,　　 Gradually disassemble the outlet pipe, gate valve and elbow with installation tools, and tighten the next section of water pipe with pipe clamping plate. In this way, disassemble the pump section by section and lift the pump out of the well. (if it is found that there is a jam during the lifting and removal process, and the customer service points shall be moved up and down, left and right for safe lifting and removal)　　The type selection planning of submersible slurry pump has a great impact on its service life and operation stability. A scientific and reasonable type selection plan will affect whether the slurry pump can achieve efficient operation. The operating power of the slurry pump is very high and the loss is small. Service life of flow passage parts of pumpDadu, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so that　　The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed

　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.　　The lift of deep well pump is calculated according to the following formula　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.Bidding,　　Some corrosive pastes containing crystals can also be transported. In the application range of slurry pump, the service life of slurry pump in this section is generally low. Of course, different minerals, abrasion　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family,VilniusSewage pump diving, when we use it, the flow is small

　　 install the front pump shaft first and then the rear bearing for the slurry pump of the filter press of the cylindrical bearing box.Meticulous workmanship,　　The of descending axial force can be used for slurry transportation in power plants, hydraulic and other professions; The mechanical seal is tight and reliable, which is mostly used to transport flammable explosive, toxic,VilniusSubmersible non clogging slurry pump, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.　　 The motor output of the large flow submersible pump is too high, there are other electric equipment on the user&#;s site, and the user&#;s Transformer composition capacity is too small to start the submersible pump. You can use a suitable transformer or turn off other electrical equipment that meets the power consumption of the submersible pump.　　The of descending axial force can be used for slurry transportation in power plants, hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, which is mostly used to transport flammable, explosive, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.Vilnius,　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation but also leak a large amount of transmitted liquid.　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body
