PortugalPipeline pumpThe power of market competition

　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.　　Is called cavitation phenomenon.Portugal,　　Shaft seal water, no dilution of pulp, good shaft seal effect. It can be used when the slurry is not allowed to be diluted.　　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,PortugalCorrosive pipeline pump, in which the constant active powerBujumbura,　　Stability and reliability of seals between pump bodies.　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance first stop the pump, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press the

　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water　　 Check and replace accessories regularly: check cables, motor insulation and screws at least once a year. If it is damaged, before starting again check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.Quality improvement,　　Slurry pump Inappropriate model is selected when selecting the pump. In actual use,PortugalVertical multistage centrifugal pipeline pump, when the load conditions do not match the model of the slurry pump, for example, the pump lift used is too high or too low, which will lead to overload, so we are selecting the pump　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much, 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, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.　　Balance of.

　　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, 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 chooseCreate brilliance,　　 In addition, the noise method directly detects the noise of the equipment in the detection process, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.　　Fire pump control cabinet generally has two control modes: one is fire hydrant control, and the other is spray pump control. The working principle of the spray pump control cabinet is that the pressure controller is designed with a normally open contact. When the pressure relay acts due to the pressure difference, the control circuit moves the main circuit　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family, when we use it,PortugalCirculating hot water pipeline pump, the flow is smallPortugal,　　Water pump is a kind of machinery that pumps energy liquid. It is a machine that converts the mechanical energy of the prime mover into the potential energy of the pumped liquid. Driven by power machinery, sewage submersible pump and seawater submersible pump.　　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 the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.
