It Is Important To Understand The Working Principle Of Submersible Sewage Pumps!

　　It is important to understand the working principle of the sewage pump under the liquid!The liquid-under-lower sewage pump is also called a liquid-under-lower sewage pump, a liquid-under-lower sewage pump, etc. It adopts the installation method above the liquid surface. The pump body works underwater and rotates the impeller to discharge the material out of the pump pipe through the long shaft driving impeller. The motor is located above the water surface and the pump top is air-cooled.It not only has the performance advantages of ordinary sewage pumps, but also overcomes the disadvantages of submersible pumps not being used in high-temperature media environments and being easy to burn the motor. The installation methods can be varied, such as fixed installation tray installation, floating barrel binding installation, and channel steel bracket installation.The length under liquid can be selected freely, just explain it before ordering, and can also be divided into single-tube and double-tube installation methods.The liquid sewage pump is made into specifications according to the length of the projected container (usually 1 to 1.5m).The working part sinks in the liquid, so there is no liquid splashing in the shaft seal; the axial and radial forces generated by the operation of the pump are supported by rolling bearings and sliding bearings, so the operation is quiet and noise-free; there is a cooling system at the sealing filler, which can use cooling water to remove heat according to the temperature of the user's medium.The parts in which the liquid sewage pump contacts the medium are made of phenolic glass fibers modified with polyvinyl butyral, and phenolic fiberglass fiberglass parts molded by high temperature. The coupling pipe and liquid outlet pipe are made of semi-dry rolling process. The impeller sleeves are assembled with phenolic plastic and the pump shaft of the liquid sewage pump. The assembly of each part under the liquid is bonded with phenolic plastic. There is no metal contact with the medium under the liquid. The corrosion resistance is reliable. The product has excellent properties such as lightweight, high strength, non-deformation, temperature resistance, and corrosion resistance. In terms of corrosion protection, it can partially replace precious metals such as aluminum stainless steel, iron and titanium alloys.The working principle of sewage discharge pump under liquid: 1. The working part of the pump is submerged in the liquid, the shaft seal has no leakage, and the area is small, the operation is quiet and noise-free, reliable use, easy maintenance, and strong corrosion resistance.2. The vertical motor is bolted to tighten the motor base, and directly drives the pump, pump body, intermediate pipe, pump frame, liquid outlet pipe, and pipe flange through an elastic coupling. It is connected with bolts to form an integral part, fixed on the bottom plate, and is installed on the container through the bottom plate.The axial and radial forces of the pump, including the water pressure generated during pump operation, the weight of the impeller and rotor, etc., are all carried by the one-way thrust ball bearings, single-row centripetal ball bearings, and the sliding guide shaft to ensure the safe and normal operation of the pump.The bearing is lubricated with butter, and the guide bearing is lubricated with the conveyed liquid.3. The liquid level must be higher than the center line of the impeller during operation.The length of the extending container L is different, and it is divided into an intermediate guide bearing structure and a structure without intermediate guide bearings.4. It is made into specifications according to the different lengths of the projected container (usually 1 to 1.5m). There is a cooling system at the sealing filler. The sewage pump under the liquid can use cooling water to remove heat according to the temperature of the user's use medium.
