　　What is the order.　　Potential is convenient and flexible. It is easy to operate. It can be operated by a fool who turns on the power supply under immersion; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.Hamburg Altona,　　 Using the fire control cabinet can improve the working efficiency of the fire pump. The fire control cabinet can meet the s that cannot be provided by a single fire pump, such as the of simultaneous startup. In some dangerous situations, a single fire pump can not meet the needs, and multiple fire pumps are required to work at the same time,　　Wheel, which are wear-resistant, corrosion-resistant, non clogging, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump and the investment is lower.Nivala,　　The balance ring is also disassembled; Then remove the last stage impeller and the key back, and the middle section including the guide vane; in addition, middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　Pump,Hamburg AltonaSubmersible sewage pump, sewage submersible pump and seawater submersible pump.　　 We must choose to consider the actual use situation when making the selection, because there will be some difference between the marked head when using and the head when using. This is because the pipe itself

　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.　　Or the liquid contains fibers. For the medium with solid particles such as paper scraps, the temperature of the medium to be transported is usually not greater than ℃.　　 Precautions for disassembly of submersible slurry pump Before disassembling the filter press, make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled, drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored,Hamburg AltonaWater well pipeline pump, it should continue to be used after maintenance. Do not dump it directlyInspection items,　　The use of water pumps for agricultural drainage and irrigation can improve the ability of agriculture to resist natural disasters, increase production and ensure income and provide material conditions for agricultural mechanization and water conservancy.　　Turn on the power supply type fool operation; It has a wide range of applications. In many cases, it belongs to a portable workstation, which can be brought wherever it is needed, because it does not need too many auxiliary facilities.　　Moreover, the leaked flammable, explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.

　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)Excellent service,Hamburg AltonaCentrifugal slurry pump,　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　At present, all screw pump manufacturers regard dry operation protection as a necessary unit for equipment procurement.　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.Hamburg Altona,　　The mixing impeller and other main flow passage parts are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non clogging and have strong sewage discharge capacity and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more thorough desilting. No auxiliary vacuum pump is required and the investment is lower. nothing　　How to avoid this situation when the equipment is in use.　　The vertical sand pumping pump is popular with a wide range of sand pumping pump users because it is easy to move. This equipment is made of high-tech endurance data. Its service life has been greatly improved, and the maintenance frequency has been reduced, the cost has been reduced, and the income has been increased.
