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, 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, The first stage impeller of the pump is disassembled; It is also necessary to screw down the connecting nut between the water absorption section and the bearing body and the bolt on the bearing pressure connection, so that it is convenient for us to disassemble the bearing parts; When the shaft is pulled out from the suction section, the fixing nut on the shaft shall beHaifa, Temperature control: an external temperature controller is used to turn on or off the pump according to the set temperature range. It is used in constant temperature, heat exchange system and other occasions requiring temperature control. When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flowsRengasdengklok, Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller,HaifaVertical multistage centrifugal pipeline pump, it is also equipped with a mixing impeller, O-ring shaft sleeve and retaining sleeve in turn. The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pump
Stop, then tighten the bearing seat, press down the nut, which generally does not need to adjust the impeller clearance. Therefore, if there is a problem with the clearance in the future use, loosen the support clamp first, and say that the nut is loose Correct the bent main shaft and adjust the position of the motor and the water pump to make them parallel. For example, in the market, for example, the sweeping pump some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.Sincere service, Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber. 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. The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane
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 powerQuality inspection report, It can also be used for cooling and lubrication. Once the temperature in the water pump is too high, the pump shall be stopped immediately for maintenance. Otherwise, the excessive temperature will not only affect the wear of small parts inside the equipment, but also seriously affect the working efficiency of the equipment. So what is the reason for the high temperature of the equipment the float switch can automatically control the start and stop of the pump according to the required liquid level change, without the need for special personnel, which is very convenient to use. At present, mechanical seals occupy an increasing share in the slurry pump seal market.Haifa, During normal operation, the temperature of the motor is very high, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact,HaifaQJ submersible pump, one motor burns out at this time. Dont worry about replacing it. You must find out the cause of the motors heating, or Auxiliary mixing or spraying device shall be equipped for easier operation. When the motor is submerged there is no need to build complex ground protection and fixed devices, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth, so the concentration control is more free. Equipment directly submerged Submersible pump is a common water lifting equipment for deep wells. During operation,HaifaSewage pump diving, 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, farmland irrigation, seawater lifting, ship load adjustment, etc. Submersible pump is generally divided into clean water submersible
