There are two Roots blowers in the domestic sewage treatment station of Hegang Power Generation Co., Ltd. Adjustment of blast aeration mode of domestic sewage station The actual sewage volume of the domestic sewage station of Hegang Power Generation Co., Ltd. is smaller than the designed value, and the sewage lifting pump is automatically controlled according to the sewage water level in the collecting basin. When the sewage water level in the collecting basin reaches the highest water level, the sewage lifting pump automatically starts running; when the sewage water level in the collecting pool reaches the lowest water level, the sewage lifting pump automatically shuts down and stops running. Therefore, the inlet and outlet water of each monomer sewage treatment tank is discontinuous and discontinuous, and sometimes there is no water in and out, until the sewage pump is operated, the sewage in the collection tank can be replaced.

Due to the discontinuity of the intermittent water in the sewage station of Hegang Power Generation Co., Ltd., it is not necessary for the Roots blower to run continuously 24 hours a day. This not only causes serious damage to the equipment, but also causes huge waste of electrical energy. Therefore, scientifically adjust the Roots blower. The operation mode, which not only saves energy, but also satisfies the use, is the preferred mode of operation for the company's domestic sewage station. According to the operating characteristics of the sewage treatment equipment of the company's domestic sewage station, it is decided to determine the operation mode of the Roots blower by the change of dissolved oxygen in the aeration tank. After comprehensive consideration of the operating and maintenance characteristics of the company's domestic sewage station electric equipment, the operation management personnel handover system and other factors, each running time is determined by the change of dissolved oxygen. When the busbar is single-pole grounded, the load on the busbar of this group can be quickly cut to another group of busbars to search or power-off the busbar without worrying about the relay protection and automatic device error due to single pole grounding. Move or refuse to move; at the same time, it can avoid long-term single-pole grounding and cause another pole to re-ground, causing short circuit of DC system. When the unit is out of service, the busbar can be cleaned without affecting the power supply to the load feeder. After the primary wiring of the MW unit 110V DC system is modified, the new wiring method is reasonable, which is convenient, reliable and safe for finding and processing the grounding point and cleaning the busbar.

Rapid Prototyping

Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer

aided design (CAD) data. At Jin Te Rui Machine Co, we believe in providing an integrated range of product development solutions to help designers, engineers, and manufacturers to develop and evaluate new products quickly, economically and with less risk. Jin Te Rui`s success in delivering excellence over the years has been its rapid prototyping service. Employing proven rapid prototype technologies, we can take your concept or design and bring it to life in just days. You will receive professional advice about the service that best suits your needs, whether that`s a prototype to test form, fit and function, or as a starting point for any of our downstream manufacturing services.
