The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started,CeresLong shaft submerged slurry pump, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power　　After that, 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.Ceres,　　 minimum gauge pressure at pump seat outlet MPa　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in useKochani, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things, liquid metal oil, acid-base night and so on. It is a good means of transport.　　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.　　In order to make the equipment perform better when it is used, but this also needs to be based on its working principle. It can not be adapted at will when it is optimized.

　　If the pump outputs more medium liquid,CeresQuotation slurry pump, 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　　If this coating is removed over time in subsequent work, the owner of the stainless steel deep well pump can use another coating to resist corrosion and hot water.　　Now you know the reason why the pump has air turbidity. In fact, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things, such as water, oil, liquid metal acid-base night and so on. It is a good means of transport.Economic management,　　The use of water pumps is related to all aspects of our life. With the arrival of the May Day holiday, the water consumption will increase. Therefore, it is necessary for us to choose a suitable water pump.　　 The slurry pump mainly aims at conveying flow, so the flow meter (meter) shall be installed in the operation monitoring system as far as possible to monitor whether the flow meets the requirements at any time; In the pipeline system, slag flushing system and pressure filtration dehydration system equipped with hydrocyclone, certain　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand,CeresVertical multistage centrifugal pipeline pump, so as to move the sand pumping place back and forth for sand pumping, so that the sand pumping area in this area forms a honeycomb,

　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.Process inspection,　　Submersible pump is a common water lifting equipment for deep wells. During operation, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling, seawater lifting, ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible　　If it can be started and operated with lubricating water, self-lubricating bearings can be used at the support, or other types of bearings (such as polymer bearings) can be used according to the design or contract requirements.　　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.Ceres,　　What is the solution to this situation?　　In addition, the sundries inside the pump body and impeller shall be cleaned. Then calibrate the pump shaft and motor shaft of the slurry pump to make them on the same horizontal line.　　 Then reinstall the equipment on the engine and install the rubber hose.
