What is vehicle urea?

During the operation of diesel engine, excessive air will inevitably lead to nitrogen oxides in the air, which are harmful pollutants to the environment. The nitrogen oxides produced by vehicle urea can be effectively decomposed into harmless nitrogen and water, and finally achieve the purpose of safe emission.

Urea pump system and use method

The invention discloses a urea pump system with pressure water seepage cleaning function and its use method. The urea pump system with pressure water seepage cleaning function includes: pressure vessel; A water seepage chamber is arranged on the upper part of the pressure vessel, and the water seepage chamber is in the shape of a square shell; The upper part of the side wall of the water seepage chamber is made of a water seepage membrane, and the inner cavity of the water seepage chamber is connected with the pressure vessel through the water seepage membrane; A first piston is built in the lower part of the water seepage chamber, and the first piston is tightly sealed with the inner wall of the water seepage chamber; First spring; Connecting shaft; The inlet pipe of the urea pump is connected with the urea tank, and the outlet pipe is connected with the pressure vessel through the first opening; Air inlet pipe; The first check valve and the second check valve are respectively arranged in the first pipeline and the second pipeline. The invention has the advantages of energy conservation, environmental protection, automatic cleaning, etc., and can be widely used in the technical field of urea pump cleaning.
