It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much,GrimbergenCorrosive pipeline pump, it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks, which are mainly to pay attention to the details and the phenomena occurred during the operation,GrimbergenFire deep well pump, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.　　For example, in the market, for example, the sweeping pump, some of which have a depth of more than meters it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.Grimbergen,　　 The casing ground wire of the electric pump shall be connected in strict accordance with relevant regulations. When the electric pump is running, it is strictly prohibited to work or move in the water of nearby devices or people, in case of accidents caused by the power distribution of the electric pump.　　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,GrimbergenSmall deep well pump, 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,Warangal,　　The other mechanical seal is a split seal, clean the part to be bound with alcohol again and wipe it dry.　　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, tighten the adjusting screw of the bearing box evenly, 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

　　If the oil seal ring of the shaft is seriously worn, replace it with a new one.　　 Determination of lift　　 If it is found that the impeller is damaged and the liquid supply is insufficient, it is necessary to replace the new impeller in time for use.Let's see,　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor and　　If there are sundries blocked, the pump will not be filled with water. When this happens again, and check the impeller. In case of damage or aging, it needs to be replaced in time, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.

　　 selection of flow: single suction pump or double suction pump shall be selected according to the flow; single suction pump or multi suction pump shall be selected according to the lift.Affordable price,　　All kinds of newly designed mechanical seals of submersible slurry pumps contribute greatly to the growth of market share.　　The treatment methods are as follows: Check the power supply voltage: if the voltage changes greatly it is caused by unstable voltage, and the use should be stopped immediately to prevent more serious consequences. Or install corresponding heat dissipation protection measures to protect the motor.　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.Grimbergen,　　The motor is scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　 determination of model: for water pump or pump with physical and chemical medium similar to water it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.
