Three advantages in the submersible sewage pump


Deyuan Pump
 

Shandong Deyuan Pump Co., Ltd. specializes in producing all kinds of pump products. Its submersible sewage pump has excellent performance, high reliability, long service life, reasonable structure and beautiful appearance, and has leading industry level. The submersible sewage pump is a new generation of energy-saving and environmentally-friendly pipeline pump researched and developed on the basis of ISG and ISW-type pipeline centrifugal pumps. IRG (GRG) vertical hot water (high temperature) circulating pump and ISWR horizontal submersible sewage pump are widely used in: energy, metallurgy, chemical, textile, paper, and high temperature hot water pressurized circulation transportation of boilers and hotels. Pump for heating system circulation; IRG type use temperature T<120°C, GRG type use temperature T<240°C, ISWR type use temperature T≤120°C.

Characteristics of submersible sewage pump: 1. Brushed DC water pump in submersible sewage pump: When the submersible sewage pump is working, the coil and the commutator rotate, the magnetic steel and the carbon brush do not rotate, and the alternating current direction of the coil is rotated with the motor. The commutator and the brush are used to complete the wear. As long as the motor rotates the carbon brush, the wear will occur. When the submersible pump runs to a certain extent, the carbon brush wear gap becomes larger and the sound will increase accordingly. After several hundred hours of continuous operation, the carbon The brush can't play the role of reversing. Advantages: The submersible sewage pump is inexpensive.

2. Brushless motor type DC water pump in submersible sewage pump: Motor type brushless DC water pump is composed of brushless DC motor and impeller. The shaft of the motor is connected with the impeller. There is a gap between the stator and the rotor of the submersible sewage pump. The water will penetrate into the motor for a long time, which increases the possibility of motor burnout. Advantages: The brushless DC motor of the submersible sewage pump has been standardized, and there are a large number of specialized manufacturers, which are relatively low in cost and high in efficiency.

3. Brushless DC magnetic drive pump in submersible sewage pump: Brushless DC water pump adopts electronic component reversing, no need to use carbon brush to commutate, adopt high performance wear-resistant ceramic shaft and ceramic bushing, and the bushing is connected with magnet through injection molding. The wear as a whole avoids wear and tear, so the life of the brushless DC magnetic water pump is greatly enhanced. The stator part and the rotor part of the magnetically isolated water pump are completely isolated, the stator and the circuit board part are sealed by epoxy resin, 100% waterproof, the rotor part is made of permanent magnet, the submersible pump pump body adopts environmentally friendly material, low noise, volume Small, stable performance. The submersible sewage pump can adjust various required parameters through the winding of the stator and can operate at a wide voltage. Advantages: The submersible sewage pump has a long service life and low noise of up to 35dB, which can be used for hot water circulation. The stator and circuit board parts of the submersible pump motor are sealed with epoxy resin and completely isolated from the rotor. They can be installed underwater and completely waterproof. The shaft of the submersible pump adopts high-performance ceramic shaft with high precision and good shock resistance.
