Sewage pump selection? Buy or buy expensive

Currently available on the market more than the sewage pump is known as non-clogging sewage pump, then whether it is the real sense of non-clogging it? Not necessarily! Often the user's sewage pump in the sewage pond in useless how long blocked by debris caused Motor burned, how to choose sewage pump, so many users headache ......

Sewage Pump Selection The most critical issue for a sewage pump is the reliability issue because the medium that needs to be delivered is a mixture of solids that contains a solid material. This problem can result in the pump being well sealed, the motor carrying capacity, the bearing arrangement, and the selection And other requirements than the average pump to high, so in the selection, we must understand clearly the sealing pump reliability and carrying capacity.

In order to improve the life of the sewage pump, most manufacturers at home and abroad are now on the pump protection system think of a way that the pump leaks, overload, over temperature and other failures can automatically alarm and automatically shut down for repair.

In the sewage pump protection system is necessary, it can effectively protect the safe operation of the pump. However, this is not the crux of the problem. The protection system is only a remedy after a pump failure. It is a relatively passive approach.

The crux of the problem should be from the very beginning, to completely solve the pump in the sealing, overload and other issues, this is a more proactive approach.

Selection precautions

Flow rate: The flow rate of the sewage pump should be selected according to the second flow rate of discharge (unit of measurement: L / s); when the displacement is adjusted, it can be selected according to the flow rate of maximum hourly discharge (unit: m³ / h).

Head: Sewage pump lift in accordance with the lifting height, calculated after the loss of the pipeline. Such as the need to transport medium is a mixture of some solid media (such as sediment), the problem makes the sewage pump in the motor carrying capacity, bearing arrangement, the pump seal and other aspects of the requirements than the average pump, in general To choose self-priming sewage pump or submersible sewage pump. In the selection and ordering, be sure to understand your choice of sewage pump sealing and carrying capacity is appropriate.

Sewage pumps used in buildings, submersible sewage pumps, submersible drainage pumps, vertical sewage pumps and horizontal sewage pumps. The vertical sewage pump and horizontal sewage pump required to set the base isolation, to occupy a certain space for the venue, it is less used in the building.

In the building, the venue is small, displacement is not big, you can choose submersible sewage pump and submerged sewage pump. The liquid sewage pump can generally be used in more important places. Its overall structure is compact, small size, small noise, easy to move and easy to install. Significant energy-saving effect, easy maintenance, without the need to build pump room, dive into the water can greatly reduce the project cost.

Public buildings and facilities should be in accordance with each drainage catchment as a unit, set up a spare pump, usually interoperability should be to reduce the long-term load pump operation and improve service life.

When pumping sewage sludge with larger media, the submersible sewage pump in different sumps should not be combined with the discharge pipe [when the submersible sewage pump is lifted to contain large debris, the submersible sewage pump should preferably be equipped with a crushing device . When lifting more fibrous wastewater, a cutting device or a large-channel submersible sewage pump may be used.

When pumping general wastewater, according to the actual situation of different submersible sewage pump sewage pipe merger discharge.

When two or more pumps share one outlet pipe, a valve and a check valve shall be installed on each outlet pipe of the pump. A single pump drainage may occur when the backflow should be set check valve. Do not allow the pressure drainage and the construction of gravity drainage pipe merged discharge.

1. Mechanical reliability, low noise, small vibration. 2. To consider the economic costs of equipment, operating costs, maintenance costs and management costs of the lowest total cost. 3. The selected model and performance meet the device flow, head, pressure, temperature, cavitation flow, suction and other process parameters. 4. The characteristics of the media must be satisfied. 1) Pumps that deliver flammable, explosive toxic or valuable media require a reliable shaft seal or a leak-free pump, such as a magnetically driven pump, diaphragm pump, shielded pump. 2) The pump conveying corrosive media, convection parts require the use of corrosion-resistant materials, such as: fluorine plastic material pump, if not corrosive, but also the appropriate selection of engineering plastics pump. 3) For pumps containing solid particulate media, convection components are required to be corrosion-resistant and wear-resistant materials, if necessary, the shaft seal is cleaned with a cleaning liquid.
