Abstract
The invention provides a water pump with a leakage inspection structure. The water pump comprises a transmission shaft, an oil seal, a water seal and a water pump body, wherein one end of the inner wall of the water pump body is connected to form a water cavity; the interior of the water pump body is connected with the transmission shaft; the oil seal is hermitically mounted at the transmission end of the transmission shaft; one side of the transmission shaft is adjacent to the water cavity; the water seal is hermitically mounted between the transmission shaft and the water cavity; and an inspection hole is reserved between the oil seal and the water seal. The water pump has the beneficial effects that when a diesel engine operates, the technical state of the water pump can be learnt in time, so that the problem of abnormal wear and the like due to the fact that lubricating oil is mixed with water as the water seal fails is solved, and the reliability of the diesel engine is improved; and meanwhile, the water pump is simple in structure, easy to implement and low in manufacturing cost, and the production cost is effectively reduced.
Description
Technical field
The invention belongs to engine water pump field, especially relate to a kind of water having and revealing inspection structure
Pump.
Background technology
The effect of cooling system is cooling diesel engine, diesel engine will be made overheated if breaking down, time serious also
There will be the fault such as scuffing of cylinder bore, tile kilning.So correctly diagnosing cooling system failure, to ensureing that diesel engine is normal
Operating is of great significance.Generally cooling system monitoring parameter mainly has water temperature, pump capacity,
Ensure that technical staff grasps the state of the art of diesel engine cooling system in time to a certain extent, it is to avoid occur
Diesel engine overheating fault.
But in actual use, owing to water pump seal damages, cause lubricating fluid enters moisture,
Have a strong impact on lubricating system reliability, and then affect Reliability of Diesel Engine.In prior art, shortage has
Effect to water seal leak condition detection methods, the safe operation to diesel engine brings hidden danger, has a strong impact on it
Reliability.
Summary of the invention
In view of this, it is contemplated that propose a kind of water pump having and revealing inspection structure, to solve water pump
Oil seal leak is difficult to find in time, and cooling water enters the problem that lubricating fluid causes diesel engine to damage.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of have the water pump revealing inspection structure, including power transmission shaft, oil sealing, water seal and water pump body,
Inwall one end of described water pump body connects formation water cavity, the inside of described water pump body and described power transmission shaft
Connecting, the driving end of described power transmission shaft seals installs described oil sealing, the side of described power transmission shaft and described water
Chamber is adjacent, seals and install described water seal between described power transmission shaft and described water cavity, described oil sealing and described water
Inspection hole is set between envelope.
Further, described inspection hole is through hole.
Further, the internal diameter in described inspection hole is 3mm.
Further, with the internal diameter in described inspection hole just to described driveshaft section be divided into naked axle, described naked
Axle is 1mm with the gap of described water pump body.
Further, the angle in described inspection hole is vertical with the placed side of described water pump body.
Relative to prior art, water pump of the present invention is revealed and is checked that pore structure has the advantage that
(1) water pump of the present invention is revealed and is checked pore structure, when checking that hole can find when dripping in time,
Avoiding lost efficacy due to water seal makes lubricating oil intake, and causes the problems such as inordinate wear, improves diesel engine
Reliability.
(2) water pump of the present invention is revealed and is checked pore structure, simple in construction, easily realizes, and makes
Low cost.
