Low-speed thrusterThe structure and performance characteristics of
Low-speed thrusterIt mainly consists of submersible motors, reducers, spiral impellers, seals, hand cranked hoisting mechanisms, installation systems, and electrical control devices.
1. Compact structure, small volume, and light weight. Easy operation and maintenance, convenient and fast installation, and long service life.
2. The blades have self-cleaning function, which can prevent debris from entangling and blocking.
3. When used in conjunction with an aeration system, energy consumption can be significantly reduced, oxygen filling can be significantly increased, and sedimentation can be effectively prevented.
4. The motor winding of the QDT low-speed thruster is F-class insulated, with a protection level of IP68. It uses imported bearings that require one-time lubrication and maintenance free, and has oil chamber leakage detection and motor winding overheating protection functions, making the operation of the motor safer and more reliable.
5. The friction material of the mechanical seal is corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel.
6. Under specified conditions, the average operating time before the first failure is not less than 10000 hours, and the overall service life of the machine is not less than 15 years.
7. The submersible propeller blades are made of elastic polyurethane or aluminum alloy, capable of withstanding varying loads, and the thrust is evenly distributedThere is a reasonableHydraulic design.

QDT low-speed thrusterSelection precautions
QDT low-speed thrusterThe selection of the mixer is a relatively complex task, and the correctness of the selection directly affects the normal use of the equipment. As a principle of selection, the mixer should fully exert its mixing function in the suitable volume, which can generally be determined by the feed rate. According to the different process requirements of sewage treatment plants, the inlet speed of the mixer should be ensured to be withinBetween 0.15~0.3m/s, if the feed rate is lower than 0.15m/s, the pushing and stirring effect cannot be achieved. If the feed rate exceeds 0.3m/s, it will affect the process effect and cause waste. So before selecting, first determine the location where the low-speed impeller will be used, such as sewage tanks, sludge tanks, and biochemical tanks; Next are the parameters of the medium, such as suspended solids content, viscosity, temperature, and pH value; Also, the shape and depth of the pool.
QDT low-speed thrusterThe required matching power is determined according to the volume, density of the stirred liquid, and stirring depth, and one or more mixers are used depending on the specific situation.

QDT low-speed thrusterThe installation system

Jiangsu Du'an Environmental Protection Low Speed ThrusterThe installation system mainly consists of a chain block, lifting bracket, lifting bracket seat, lifting ring chain, guide rod, limit bracket, base, etc. The low-speed impeller moves up and down along the guide rod through the guide wheel, and the lifting bracket is installed on the lifting bracket seat and can rotate around its positioning axis360 °, for the convenience of installation and maintenance, the limit frame of this installation system is in a "T" shape, with the upper end in contact with the low-speed thruster body, and horizontally connected to the guide rod connecting plate with bolts (the guide rod connecting plate is welded to the guide rod after the low-speed thruster position is adjusted correctly), and the lower end is fixed with expansion bolts. To increase the reliability of the low-speed thruster during operation and reduce the vibration during the operation of the submersible low-speed thruster, V-shaped rubber shock absorbers are added to the low-speed thruster and limit frame.

QDT low-speed thrusterThe installation system is made of stainless steel and carbon steel anti-corrosion materials for selection;
