Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters not because the slurry pump has a problem, but because　　Other ysts believe that, at least in recent years, the situation of power shortage will continue, and China&#;s economic growth trend will maintain a high speed. Therefore, the contradiction between power supply and demand is still prominent in recent years,TimmingsRubber lining submerged slurry pump, which is undoubtedly an opportunity for it and the generator industry. In water pumps and generators, especiallyTimmings,　　 Constantly observe the instrument, check the electrical equipment, and measure the insulation resistance every half a month. The resistance value shall not be less than . megohm.　　About %), the sewage pump is usually driven by a motor which also requires some time og quantity when switching on and off, so in fact, it can be adjusted to a certain extent during use. The submersible slurry pump needs to use a line when in use　　According to the user&#;s requirements, 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.

　　 If the pump is equipped with a vacuum gauge or pressure gauge,TimmingsHH slurry pump, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.　　. Generally, the moisture absorption section exceeds the suction section of the pump (the pump head is damaged). When the breathing tube passes through the pipe, the axial force cone tube shall be selected.　　 Pipeline layout: Firmly support the water pipe and drain pipe to prevent the force of the pipe from acting on the submersible slurry pump.reform,　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump,TimmingsSubmersible sewage pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.　　 confirm whether the pressure capacity of the pipeline meets the requirements, and conduct hydrostatic test if necessary.

　　Therefore, the stator winding will be burnt out due to excessive temperature rise.Packaging strategy,　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump　　Check the three-phase current with an ammeter on the control panel. If the phase power supply is found to be insufficient, the power supply of the submersible pump shall be turned off immediately. Check whether the cable connector, connection point and power switch contact are in poor contact and whether they are the main line. Check whether the circuit wiring is broken or loose, or whether the fuse is damaged or burnt out　　Some impurities will entangle the impeller, so generally, so there is no need to worry about getting stuck in the process of transporting sewage.Timmings,　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed　　Screw it down, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.　　Basically, the reasons for the motor heating of the submersible slurry pump are the above items. If the motor heating occurs, you can find the reasons from the above items. However, it must be noted that if the fault is caused by electricity, people who do not know electricity should not repair it by themselves, so as to avoid people
