Abstract
The utility model relates to a diesel engine cooling pump, relating to a cooling pump; one side of a pump body is provided with a bearing box which is internally provided with a bearing; the bearing is internally provided with a pump shaft; the bottom part of the bearing box is provided with an oil draining plug; before the cooling pump fails and is disassembled for repairing, the oil draining plug is opened, the lubricating engine oil in the bearing box is drained off, thus avoiding the outward leakage of the engine oil in the bearing box when in disassembly and repair, having no pollution to the environment and being applicable to the diesel engine cooling pump.
Description
Technical field
The present invention relates to coolant pump, say it is a kind of diesel engine coolant pump in detail.
Background technique
We know, existing diesel engine coolant pump, be provided with bearing housing in the pump housing one side, be provided with bearing in the bearing housing, be provided with pump shaft in the bearing, the oil lubricating that bearing relies on diesel engine to supply with has machine oil, this diesel engine coolant pump all the time in the bearing housing, because the pump housing one side is provided with bearing housing, be provided with bearing in the bearing housing, be provided with pump shaft in the bearing, the oil lubricating that bearing relies on diesel engine to supply with, all the time there is machine oil in the bearing housing, when coolant pump broke down field-strip, the machine oil in the bearing housing leaked befouling environment.
Summary of the invention
The technical problem that the present invention solves is that when the solution coolant pump broke down field-strip, the machine oil in the bearing housing leaked, problem of environment pollution caused, when providing a kind of coolant pump to break down field-strip, avoid the machine oil in the bearing housing to leak diesel engine coolant pump free from environmental pollution.
Technological scheme of the present invention is, the pump housing one side is provided with bearing housing, is provided with bearing in the bearing housing, is provided with pump shaft in the bearing, and the main structure characteristics are that the bearing housing bottom is provided with oil drain plug.
The invention has the beneficial effects as follows that because bearing housing bottom is provided with oil drain plug, coolant pump breaks down before the field-strip, opens oil drain plug, and the lubricating oil in the bearing housing is drained, the machine oil in the time of can avoiding field-strip in the bearing housing leaks, and is free from environmental pollution.The present invention is applicable to the diesel engine coolant pump.
Description of drawings
Accompanying drawing is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation.
Embodiment
Diesel engine coolant pump as shown in the figure, the pump housing 1 one sides are provided with bearing housing 2, be provided with bearing 5 in the bearing housing 2, be provided with pump shaft 3 in the bearing 5, bearing housing 2 bottoms are provided with oil drain plug 4, because bearing housing 2 bottoms are provided with oil drain plug 4, coolant pump breaks down before the field-strip, opens oil drain plug 4, and the lubricating oils in the bearing housing 2 are drained, machine oil in the time of can avoiding field-strip in the bearing housing 2 leaks, and is free from environmental pollution.
