Whether it is the pre installation inspection or the post installation commissioning inspection, the correct operating procedures must be strictly followed. Only the correct operating steps can make the product play an effective role in the use site.　　After that, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.Iraq,　　 Determine the head h. After the flow is determined, determine the inlet and outlet pipe diameters of the pump, complete the layout of the whole pipeline, and determine the head. In the actual selection, the resistance coefficient of the pipeline is often too large. In addition, when selecting the pump model, a head margin is added, resulting in　　Moreover, the leaked flammable, explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.Comendador,　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.　　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

　　After that, 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.　　Driven by the pump products represented by stainless steel pipeline pumps, the whole pump industry is constantly moving forward, and with the raw material market driven by this, new stainless steel materials are constantly coming out. The continuous improvement of various technologies and specifications has driven the whole industrial chain to a higher direction.　　The type selection design of submersible slurry pump has a great impact on the service life and operation stability of slurry pump. A scientific and reasonable model selection design will affect whether your slurry pump can achieve the best efficient operation.Direct labor,　　 The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.　　Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry',IraqSubmersible sewage pump, which is wear-resistant and particle passing.　　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

　　What is the solution to this situation?Interpretation and observation,　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.　　Microcomputer controller LW light: cause: the light is on and the machine stops, the water level is low, the water level returns to normal, and the machine starts automatically.　　What is the solution to this situation?Iraq,　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand,IraqWQ submersible sewage pump, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should choose　　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, remove the impellers, middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　In order to ensure the demand for water and electricity for production and living, hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this it and the generator naturally become popular
