Abstract

The invention provides a multi-hot-water-pump linkage control device for diesel engine test run. The multi-hot-water-pump linkage control device comprises frequency converters, a PLC, a first liquid level sensor and a second liquid level sensor which are matched with hot water pumps one by one. Each frequency converter is respectively connected with the PLC. The first liquid level sensor is installed in a hot water pool, and the second liquid level sensor is installed in a cooling tower. Liquid level data collected by the first liquid level sensor and the second liquid level sensor are sent to the PLC, the PLC controls frequency data of each frequency converter according to the received liquid level data, and the frequency converters adjust the operation rotating speed of the hot water pumps through the frequency data. Meanwhile, the invention provides a diesel engine test run cooling system provided with the multi-hot-water-pump linkage control device. Liquid level changes in the hot water pool and the cooling tower are dynamically responded to, the problem that the liquid level changes in the hot water pool are too large is solved, and the purpose of liquid level dynamic balance in the hot water pool and the cooling tower is achieved.

Description

technical field [0001] The invention relates to the technical field of diesel engine test run, in particular to a diesel engine test run cooling system and a plurality of hot water pump linkage control devices thereof. Background technique [0002] A large amount of cooling water is used during the test run of the diesel engine. The cooling water turns into hot water after passing through the diesel engine system. It needs to be cooled by the cooling tower and then recycled. When overflow occurs on the cooling tower, it is necessary to ensure that the water levels in the two pools are dynamically balanced. [0003] The hot water cooling system in the workshop is equipped with multiple hot water pumps to pump the hot water used in the diesel engine in the hot water pool to the cooling tower for cooling. According to the difference in the liquid level in the hot water pool, different numbers of hot water pumps are started separately to avoid the liquid level in the hot water ...
