　　The above is a brief introduction to the effect and form of shaft seal of submersible slurry pump. Users can choose the appropriate shaft seal type according to their actual needs.　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.Vishkov,　　It is not allowed to operate the electric pump under the condition of low lift for a long time (generally, the operating lift shall not be less than % of the rated lift), which shall be controlled within the recommended operating lift plan as far as possible to prevent the electric pump from burning out the motor due to overload. Pumps without self circulating cooling equipment prevent all of them from being exposed to the water for a long time　　There are differences.Kampene,　　 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.　　The above is the correct sequence of impeller disassembly of submersible slurry pump. Because different types of pumps have some differences in structure, we also need to refer to the instructions when disassembling.　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one

　　Is called cavitation phenomenon.　　Finally, select the appropriate pump model according to the determined Q and H. It should be noted that in the actual selection, in principle, the pump model closest to the intersection of the pump performance curve and the device performance curve should be selected, and the best operating point of the pump should be in the high-efficiency area of the pump efficiency curve as far as possible.　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other, or the impeller will be stuck due to impurities such as water and grass when the pump pumps waterDesign brand,　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft,VishkovSelf priming slurry pump wholesale, and successively install the bearing inner race, bearing gland and retaining sleeve　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.

　　 If the power cord is not well contacted, it will also lead to the burning of the motor.Good quality,　　In recent years, the demand for submersible slurry pumps has increased greatly. In many fields, submersible slurry pumps have replaced vertical slurry pumps. What are the differences between the two? Let&#;s yze.　　However, with the increase of pump operation time, it is bound to be accompanied by the decrease of pump efficiency and the wear of flow passage components. The most serious parameter affecting the pump characteristic curve is the wear of the pump impeller. After the wear of the impeller, it is equivalent to the downward movement of the pump H-Q curve which reduces the flow and head　　 A vent pipe is installed at the bottom of the pump, water will be injected into the bottom of the slurry pump through the vent pipe,VishkovSplit vertical pipeline pump, so that a sand water mixture will be formed at the bottom of the slurry pump, so that the slurry pump can be started normally. The advantage of this approach is that even ifVishkov,　　According to the user&#;s requirements,VishkovBooster pipeline pump, the motor can add a variety of protection devices such as water inflow detection and overheating so that the product can operate safely for a long time under adverse working conditions.　　Many users, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar including new practitioners of slurry pumps, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?　　According to the user&#;s requirements
