Problems solved by technology

The engines used in the current equipment, especially the diesel engines, will produce a large amount of exhaust gas when they are working. Cracks in the pipe can easily cause mining accidents
At the same time, the airflow resistance in the exhaust pipe made of general cast iron is relatively large, which makes the exhaust efficiency low.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, an explosion-proof diesel engine intake and exhaust manifold is made of aluminum alloy and includes an intake pipe 1, an exhaust pipe 2 and a cooling water channel 3. The inner space of the cooling water channel 3 enables the gas passing through the intake pipe 1 and the exhaust pipe 2 to exchange heat with the cooling water in the cooling water channel 3 through the pipe wall, thereby reducing the gas temperature; the cooling water channel 3 is provided with a water inlet 4 and water outlet 5, while the cooling water channel 3 is also provided with a connector 6, which communicates with the auxiliary water tank, and the auxiliary water tank can be supplemented with cooling water if necessary; between the explosion-proof diesel engine intake and exhaust main pipe and the diesel engine cylinder head The effective width of the explosion...

Abstract

The invention discloses an intake-exhaust manifold of an explosion-proof diesel engine. The intake-exhaust manifold of the explosion-proof diesel engine comprises an intake pipe, an exhaust pipe and a cooling water channel, wherein the intake pipe and the exhaust pipe are a whole. The whole penetrates through the inner space of the cooling water channel, and a water inlet and a water outlet are formed in the cooling water channel. The intake-exhaust manifold of the explosion-proof diesel engine can reduce the gas temperature of the intake pipe and the exhaust pipe, thus safety performances of the intake pipe and the exhaust pipe are improved, and meanwhile, airflow resistances in the intake pipe and the exhaust pipe are reduced.

Description

technical field [0001] The invention belongs to the field of diesel engine parts, in particular to an explosion-proof diesel engine intake and exhaust manifold. Background technique [0002] Because there are a lot of flammable and explosive substances in the coal mine area, the equipment used in the area needs to take explosion-proof measures, otherwise it is easy to cause mine accidents. The engines used in the current equipment, especially the diesel engines, will produce a large amount of exhaust gas when they are working. Cracks appear in the pipe, which can easily cause mine accidents. At the same time, the air flow resistance in the pipe of the exhaust pipe made of general cast iron is relatively large so that the exhaust efficiency is low. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an explosion-proof diesel engine inlet and exhaust manifold that can re...
