Abstract
The utility model provides a compound sealing diesel engine cooling pump which comprises a belt pulley (1) installed on a shaft, a bearing (3), an impeller (10), a bearing seat (2) and a pump body (11), wherein, a water sealing body (6) outside the shaft (12) is installed on a cavity of the bearing seat; a ceramic ring (7) and a ceramic ring (8) are installed together, the shaft is also provided with oil sealing (5), and the bearing seat is provided with a drainage hole (13). The utility model has the advantages of simple structure, reliable use, long service life, convenient maintenance and good sealing effect, and also has the advantages that the erosion of hot water to butter and the bearing is eliminated, the sharp abrasion of the bearing is avoided, and the service lives of the bearing and the cooling pump is enhanced.
Description
The utility model provides a kind of improved diesel engine coolant pump, the coolant pump on 195 diesel engines.
195 diesel engines are widely used, but the sealing of the coolant pump of its adapted is to rub by the end face that spring promotes water seal rubber, Square consisting of two isosceles right-angled triangles and bearing support boss to realize.The parts of bearing the sealing task particularly water seal spring all are subjected to the etch of 60～80 ℃ of hot water, and the time is long slightly, and Sealing will incrustation, and spring also follows the string because of corrosion.Square consisting of two isosceles right-angled triangles continues wearing and tearing, causes poorly sealed generation to be leaked.Hot water leaks into bearing portion, is mixed into thin oil water mixture with butter, makes poor lubrication, and bearing sharply weares and teares, and has seriously shortened bearing life.And behind the replacing bearing, because axle is former by corrosion, therefore poorly sealed generation trace leaks, thereby causes the rapid generation of the problems referred to above, and working life is extremely short.
The purpose of this utility model provides a kind of compound seal formula diesel engine coolant pump, to strengthen sealing effect, the working life of improving bearing and whole coolant pump.
The utility model is to realize like this, it comprise installation the axle on belt pulley, bearing and impeller, bearing has bearing support outward, impeller outer has the pump housing, grease cup is arranged on the bearing support, and axle is outer to have the water seal body to be installed on the bearing support, and the ceramic ring on the water seal body and another ceramic ring are installed together, position near bearing on axle is equipped with oil sealing, on the bearing support between oil sealing and the water seal body weep hole is arranged.
Adopt the compound seal formula diesel engine coolant pump of said structure, owing in the water seal body spring is arranged, this spring does not contact with water, has therefore avoided spring to get rusty because of the water logging erosion of being heated.Abrasive end face between two ceramic rings is highly polished, good seal performance, and the ceramic ring extreme hardness is difficult for abrasion, long service life, it is convenient to change, and can whole coolant pump be scrapped because of changing.
Below in conjunction with description of drawings concrete structure of the present utility model.
Fig. 1 is the schematic representation of the utility model structure.Fig. 2 is the schematic representation of water seal body structure in the utility model.
As shown in drawings, the compound seal formula diesel engine coolant pump of the utility model, comprise the belt pulley (1) that is installed on the axle (12), bearing (3) and impeller (10), bearing support (2) is arranged outside the bearing (3), the pump housing (11) is arranged outside the impeller (10), grease cup (4) is arranged on the bearing support (2), axle (12) is outer to have water seal body (6) to be installed on the bearing support inner chamber, ceramic ring on the water seal body (7) is installed together with ceramic ring (8), the position of going up near bearing (3) at axle (12) is equipped with oil sealing (5), on the bearing support (2) between oil sealing (5) and the water seal body (6) weep hole (13) is arranged.
Ceramic plate (8) is installed together by lining ring (9) and ceramic ring (7).
The axle of oil sealing (5) helps effect to be: 1, avoid butter because of adding too much or the too high generation grease that overflows of temperature, stop up weep hole.2, because the operating conditions of this oil sealing is good, be longer than the water seal body working life, when the wearing and tearing of water seal body were leaked, this oil sealing can prevent that cooling water from entering bearing support.3, in case of emergency can replace water seal.In the machine works process, the water seal body damages, and the weep hole water outlet if having little time maintenance, can be blocked weep hole, continues to use.After finishing, work changes the water seal body again.
Fig. 2 has represented the structure of water seal body, and spring (14) has ceramic ring (7) in the inside of water seal body (6) outside the water seal body (6).
Claims (2)
1, compound seal formula diesel engine coolant pump, comprise the belt pulley (1) that is installed on the axle (12), bearing (3) and impeller (10), bearing support (2) is arranged outside the bearing (3), the pump housing (11) is arranged outside the impeller (10), grease cup (14) is arranged on the bearing support (2), it is characterized in that, outside described axle (12), there is water seal body (6) to be installed on the bearing support inner chamber, ceramic ring on the water seal body (7) is installed together with ceramic ring (8), the position of going up near bearing (3) at axle (12) is equipped with oil sealing (5), on the bearing support (2) between oil sealing (5) and the water seal body (6) weep hole (13) is arranged.
2, require 1 described a kind of compound seal formula diesel engine coolant pump as right, it is characterized in that, described ceramic ring (8) is installed together by lining ring (9) and ceramic ring (7).
