[0027] This utility model provides an automatic cooling water filling system for a reciprocating natural gas compressor unit, such as... Figure 1As shown, the filling system in this embodiment includes a storage tank 1, a cooling water tank 2, pipes, a liquid pump 3, a safety valve 6, and a control device. The storage tank 1 stores the cooling liquid and is generally located on the ground. The cooling water tank 2 is above ground level and connected to the cooling channel of the compressor unit. The cooling water tank 2 is equipped with a level gauge to detect the cooling liquid level; in this embodiment, a float level gauge is used. The pipes connect the storage tank 1 and the compressor cooling water tank 2. The pipes are equipped with an electric valve 4 and a bypass pipe L3. Both ends of the bypass pipe L3 are connected to the pipes, with one end connected upstream of the electric valve 4 and the other end connected downstream. The bypass pipe L3 is equipped with a manual valve 5. The liquid pump 3 is located on the pipes and near the storage tank 1, drawing cooling liquid from the storage tank 1 and delivering it to the cooling water tank 2. In this embodiment, the pipes are also equipped with a safety valve 6, the overflow port of which is connected to the storage tank 1 via a back pressure pipe L4. The control device is connected to the level gauge, the liquid pump 3 and the electric valve 4 respectively, and can control the opening and closing of the liquid pump 3 and the electric valve 4 according to the data transmitted from the level gauge.

[0028] When the liquid level indicated by the level gauge reaches the set minimum level, the control device starts the liquid pump 3 and opens the electric valve 4 to begin replenishing the liquid. When the liquid level indicated by the level gauge reaches the set maximum level, the control device closes the liquid pump 3 and the electric valve 4 to stop replenishing the liquid. In case of a malfunction of the electric valve 4, the manual valve 5 of the bypass pipeline L3 can be operated to ensure normal replenishment. Therefore, the automatic cooling water replenishment system for the reciprocating natural gas compressor unit of this invention can achieve automatic replenishment, requiring almost no manpower, improving replenishment efficiency, avoiding the dangers of working at height, and allowing manual operation to be switched to ensure replenishment in case of a malfunction of the automatic control device or the electric valve 4. In addition, if the electric valve 4 malfunctions and cannot be opened during replenishment, it is difficult to detect in time, making it difficult to open the manual valve 5 in time. The safety valve 6 can prevent the pipeline pressure from increasing and causing danger.

[0029] like Figure 1 As shown, in this embodiment, the filling system includes five cooling water tanks 2, and the pipeline includes a main pipeline L1 and five branch pipelines L2. One end of the main pipeline L1 is connected to the storage tank 1, and one end of each of the five branch pipelines L2 is connected to the other end of the main pipeline L1. The other ends of the five branch pipelines L2 are connected to the five cooling water tanks 2 respectively. The liquid pump 3 and the safety valve 6 are located on the main pipeline L1. Each branch pipeline L2 is equipped with an electric valve 4 and a bypass pipeline L3. When the liquid level of a cooling water tank 2 reaches the set minimum liquid level, the control device opens the liquid pump 3 and the electric valve 4 on the branch pipeline L2 to replenish the cooling water tank 2.

[0030] In this embodiment, the main pipeline L1 is also equipped with a filter 7, which is located between the liquid storage tank 1 and the liquid pump 3. The filter 7 can filter the cooling liquid before pressurizing and transporting it, preventing impurities from damaging the pipeline, valves, and other components. The main pipeline L1 is also equipped with a pressure gauge 8, which is located between the liquid pump 3 and the safety valve 6, and is used to detect the pressure of the main pipeline L1.

[0031] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
