Axial pump normal operation and its installation location has a great relationship, the installation should meet the following conditions: â‘ In front of the pool to be set trash rack to prevent debris and plants into the pump, affecting the plastic The normal operation of the pump magnetic pump may seriously damage the pump parts; â‘¡ Note that the shape of the inlet and the pump arrangement should not make the pump at work when the surface of the funnel whirlpool, but should not have the phenomenon of uneven water; â‘¢ According to the use of the pump Manual requirements, the pump impeller in the surface below the water enough depth of submergence; â‘£ inlet bell mouth and into the bottom of the pool, the pool wall and the pump and the pump there is a certain distance. Axial Flow Pump Installation Notes (A) Preparation before installation: 1. The parts of the water è¥ shipped to the installation site must be fully inspected, pay attention to complete disassembly tools, all parts of the absence of defects in the transport process . 2. Clean the parts of the pump surface with rust, grease and burrs and so on. 3. In accordance with the outline of the pump installation drawings to check the elevation of the foundation, the quality and depth of the embedded ground screw is in line with the provisions. 4. Prepare installation tools, measuring instruments, lifting equipment and other auxiliary materials. 5. Check the pump shaft is bent or damaged, and strictly check the coupling, flange and pump shaft centerline concentric, the eccentric error shall not exceed the value specified in the manual. (B) the order of the pump installation Pump base, casing, moving blades and other hanging outside the installation location. In accordance with the pump shape icon high, preliminary correction of the pump base position. After the guide vane body and the middle take over the flange screw together, put them together on the base, correct the position of the middle take over pipe so that its axis is concentric with the center line of the suction pipe of the water pump, and check the flange Degree of surface level. The elbow will be hoisted in the middle take over, and hanging wire method proofing the bearing hole of the outlet pipe, and guide vane body bearing hole concentric. (C) the installation of the next two rubber bearings will pump shaft together with the coupling into the rubber bearing hole, the bottom of the pump shaft jack can be used to support and correct the verticality of the pump shaft, pump shaft and the gap between the rubber bearings to In line with the provisions, and pay attention to the rubber bearing surface may not be in contact with the grease. Install the pump impeller and impeller outer ring, the measurement of the gap should be in the range of 1? 2.15mm, the gap must be uniform around the installation of the blade center line elevation should meet the design requirements, the error within the specified range. The base of the base bolt in the pump body correct, before grouting, grouting to ensure the combination of old and new concrete. Pump shaft and impeller installation and correction, the impeller outer ring, casing and base connection, filled packing ring should be made oblique joints, and the adjacent ring seam position should be staggered with each other. Base and concrete filled with grouting, must reach full contact, the assembled pump should ensure that the combination of surface operation without leakage, the combined screw cap should be tightened, and in accordance with the requirements of the drawings fitted with a lock washer . Packed stuffing box, so it does not press too tight, to be adjusted after commissioning, squeezed to a drop of continuous drops is appropriate. The direct drive of the vertical motor is paired with the factory. The concentricity of the pump and the motor should be checked. There must be a clearance of 4 ~ 6mm between the two planes. Pump installed after the pipeline installation, we must pay attention to the weight of the outlet pipe shall not be supported on the pump, should be erected stent.
