**Application** In cases where a single vacuum pump is not suitable for a specific process due to limited pumping speed or insufficient ultimate vacuum, the DYK series vacuum pump unit offers an efficient solution. This system combines a Roots pump as a booster and a rotary vane pump as a backing pump. The exhaust from the Roots pump is connected to the suction side of the backing pump, enabling high pumping speed at higher vacuum levels. The unit is equipped with an air cooling system, a cooling water system, vacuum valves, ventilation valves, compensators, and a vacuum meter. It is highly efficient, reliable, and consumes less power. It can be customized and mounted on base frames for immediate use or offered on trailers to meet user requirements. The DYK unit is widely used in vacuum metallurgy, vacuum drying, welding, chemical processes, laboratories, power stations, and other industrial vacuum applications, especially for vacuum transformers and other electrical equipment operations.
**Features** 1. The Roots pump automatically starts with the backing pump via an electrical-contact vacuum meter. 2. The powerful rotary vane backing pump ensures sufficient backing pressure, allowing the diffusion pump to maintain full pumping speed and ultimate vacuum. 3. The pumping unit includes a vacuum valve at the inlet and a rough vacuum line (bypass), making it particularly efficient for rapid evacuation cycles. 4. The high-vacuum pump unit offers outstanding energy savings, high efficiency, reliability, and low power consumption.

Other Additives

At present, the overcharge protection of lithium-ion batteries is generally implemented by a dedicated overcharge protection circuit. The use of additives to achieve battery overcharge protection is of great significance for simplifying the battery manufacturing process and reducing battery production costs.
