The invention discloses an operative condition control device for a booster of a marine diesel engine, which is connected between an air cylinder and the booster of a marine diesel engine and comprises a first pneumatic butterfly valve, a second pneumatic butterfly valve, a first electromagnetic valve, a second electromagnetic valve, a rotation speed sensor and a system control box. The first pneumatic butterfly valve and the second pneumatic butterfly valve are connected with the booster, the first electromagnetic valve and the second electromagnetic valve are connected with a control air source, the first electromagnetic valve is connected with the first butterfly valve and the system control box respectively, the second electromagnetic valve is connected with second pneumatic butterfly valve and the system control box respectively, and the rotation speed sensor is installed on the marine diesel engine and is connected with the system control box. The operative condition control device has the advantages of being simple to install, safe to operate, various in control modes, convenient to maintain, low in invest cost and the like.
Description
technical field [0001] The invention relates to marine diesel engine equipment, in particular to a control device for the operating state of a marine diesel engine supercharger, and belongs to the technical field of diesel engines. Background technique [0002] Affected by the financial crisis since 2008, the international shipping market has continued to slump. In order to save ship operating costs and improve economic efficiency, major shipowner companies and ship operating companies have explored various ways to reduce costs. [0003] According to relevant statistics, the unit fuel consumption of marine diesel engines accounts for about 40%-50% of the daily operating costs of ships. Shipping companies have put forward higher and higher requirements for the fuel consumption of marine diesel engines in order to improve their own operating profits. At present, there are different ways to reduce the fuel consumption of diesel engines. Some of them are to choose diesel engines...
