the front and rear bearing glands are equipped with oil seals which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump,Masjid SuleimanSubmersible slurry 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)Masjid Suleiman,　　ZGB and other series, with complete models. Most of the vertical slurry pumps are AF foam pump, SP submerged slurry pump, ZJL submerged slurry pump and other series, with complete models, flow passage parts and accessories; Third from the number of impellers, the type of slurry pump is divided into single-stage slurry pump　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing bodyCatamayo,　　 To ensure the efficient operation of the submerged slurry pump, the clearance between the impeller and the front guard plate must be adjusted regularly to keep it between (.-mm). In addition to monitoring the flow and pressure during the operation of the pump, the service life of the flow passage parts of the pump is relatively long, saving production costs.　　What?

　　 In addition,Masjid SuleimanCorrosive pipeline pump, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.　　 transmission device type (gearbox transmission, flat belt transmission, V-belt transmission)　　Yes,　　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, in which the constant active power　　If the oil seal ring of the shaft is seriously worn, replace it with a new one.　　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.

　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motorWord of mouth recommendation,　　 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　　 connection mode of lifting pipe (flange connection and threaded connection)　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pumpMasjid Suleiman,　　 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.　　What stands out is the sealing of the container. The seal is easy to install and maintain, stable and reliable, but the price is quite expensive.　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, for submersible slurry pump
