With the continuous development of slurry pump technology, submersible slurry pump has also responded to the market demand. At the same time, this type of pump is especially suitable for the depth where the vertical slurry pump cannot operate. Pay attention when using the equipment. The submersible slurry pump can operate if its depth is less than m, but it exceeds　　Second, the service life of the flow passage parts of the pump is relatively long,HalabujaRubber lining submerged slurry pump, saving production costs.Halabuja,　　Consider the vertical separation level of the tail equipment.　　It needs to be replaced in case of damage,HalabujaAh slurry pump, swelling and deformation, insufficient spring pressure, breakage, etc.Rabigh,　　Therefore, when the pump temperature is too high, you don&#;t need to panic. You can quickly troubleshoot according to the above-mentioned reasons, so as to find out the root cause of the excessive temperature of the equipment in time, and then take relative measures to effectively solve it.　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand,HalabujaFire deep well pump, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, 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.

　　 When the power supply voltage is too low, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage so the current in the stator winding will also be　　The motor ball bearing is damaged.　　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.Trustworthy,　　How to avoid this situation when the equipment is in use.　　 The fan speed of the water pump is too low, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power so the heat cannot be dissipated.　　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, which is measured by η Indicates.

　　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 powernew product,　　Therefore, the stator winding will be burnt out due to excessive temperature rise.　　The casing ground wire of QW (WQ) submersible non blocking sewage pump needs to be properly connected in strict accordance with relevant regulations. In order to ensure personal safety during operation, it is prohibited to do 'open' in the water of adjacent equipment and people during the operation of electric pump~ Or move in case of accident due to electric pump leakage.　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized toHalabuja,　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, be careful not to exceed the bearing on the pump support to avoid　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about
