Submersible sewage pump selection points

Submersible sewage pump for vertical arrangement, pump and motor coaxial, using a unique single or double blade impeller structure, greatly improving the dirt through the ability, with high efficiency, anti-wrap, no clogging, automatic coupling, high reliability and automatic Control and other advantages, in the discharge of solid particles and long fiber garbage, has a unique function. Mainly used for municipal engineering, industry, hospitals, construction, hotels, restaurants and other industries. For the discharge of solid and a variety of long fibers of sludge, waste water, urban sewage (including corrosive, aggressive media occasions).
Selection of submersible sewage pump
 1, must be selected in strict accordance with the international ISO 9906 or the current scale of the existing production and production, and through the power of the giant mechanism of comprehensive testing of qualified submersible sewage pump brand.
    2, when there are a number of brand products to choose from, should be for the main components of submersible sewage pump material, processing accuracy, equipment appearance, over-current components necessary function (large channel, anti-surround entanglement, anti-blocking, etc.) and additional functions Long fiber cutting tear, automatic mixing to prevent dirt precipitation board, etc.), suppliers promise no endurance years of use, after-sales service, offer and other aspects of comprehensive comparison, merit. Indoor sewage pool should be installed closed well cover, set the ventilation tube.
 3, submersible sewage pump If used to lift the erosion of waste water, the pump should use stainless steel and other erosion-resistant materials.
 4, according to user needs with automatic safety control cabinet, the pump leakage, leakage, overload and over-temperature monitoring, to ensure reliable and safe operation of the pump. The following are the same as the "
 5, according to the needs of users to promote the discharge of sewage (waste) water, water quality and sewage pool (set wells) set the location, fair to determine the required flow of sewage pump and head, to determine the pump specifications.
    6, the building outdoor sewage pool can be installed non-closed manhole, no ventilation tube.
    7, according to the characteristics of sewage, waste water, decided to use the type of pump, whether the need to use cutting grinding, is the choice of whirlpool impeller is still flow channel impeller, is a single channel is still dual flow channel (the same premise, Road anti-blocking function is better).
    8, the choice should be used to understand the submersible sewage pump in the normal use of the premise of unimpeded working time, mechanical seal life, bearing rated life, motor design life, motor insulation level, the motor should be able to withstand the number of stops per hour and so on. Closed covers are gray cast iron, cast aluminum and ductile iron.
    9, basement diving sewage pump should be set to double power to prevent power.
    10, submersible sewage pump should have leakage protection devices and overheating or overload protection device, a sealed leak monitoring device and a reliable grounding device.
    11, stator with F-class insulation, with thermal protection components.
Submersible sewage pump use conditions
   1, the medium temperature shall not exceed 60 ° C, severe 1.0 ~ 1.3kg / dm3, PH value in the range of 5 ~ 9.
   2, no internal flow circulation cooling system of the pump, the motor part of the liquid surface shall not exceed 1/3.
   3, under normal circumstances, the pump must be used within the scope of use to ensure that the motor is not overloaded, for the use of the whole head range should be specified in the order, so that manufacturers manufacturing.
   4, in the course of running the pump motor current shall not exceed the rated current of the motor.
   5, submersible sewage pump motor rated voltage 380V, frequency 50HZ three-phase AC power supply (other voltage and frequency requirements can be customized)
