CalvinaVortex pump and pipeline pumpPrinciple of correct working direction

　　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.　　Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First, we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.Calvina,　　 transmission device type (gearbox transmission, flat belt transmission, V-belt transmission)　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active powerSedhiou　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed,CalvinaQJ submersible pump, because it does not need too many auxiliary facilities.　　 Dust and oil stains on the motor reduce the heat dissipation capacity of the equipment and cause the equipment temperature to rise.　　 The submersible slurry pump needs to be inspected after reassembly. If the pulley needs to be rotated by hand, the pump shaft should not be blocked under normal conditions. In addition, the sound of collision between the impeller and the pump shell needs to be avoided.

　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.　　Fire pump control cabinet generally has two control modes: one is fire hydrant control, and the other is spray pump control. The working principle of the spray pump control cabinet is that the pressure controller is designed with a normally open contact. When the pressure relay acts due to the pressure difference, the control circuit moves the main circuit　　Compared with the vertical slurry pump,CalvinaPipeline pump body, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping on board, prospecting, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pumpmanagement　　It needs to be replaced in case of damage, insufficient spring pressure, breakage, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.　　 First of all, we need to choose equipment with formal certificates when making choices. We must avoid buying some obsolete or inferior products. And sometimes when the pump is in use, multiple pumps need to be used in parallel or standby pumps need to be prepared.

　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.investment,CalvinaCorrosive pipeline pump,　　It is also necessary to clean the ventilation duct to avoid blockage.　　 particle size (maximum and minimum) mm　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.Calvina,　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mm　　Submersible slurry pump is a kind of pump used in mines. Do you know the effect and form of its shaft seal? Let&#;s have a look.　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.
