Description
Technical field
The utility model is related to a kind of horizontal thin oil lubricant parts of bearings, particularly a kind of improvement thin oil lubricant fuel door
Horizontal multi-stage pump bearing bracket.
Background technology
In the design process of horizontal type multi-stage pump, in the case that duty ratio is larger, bearing all uses the radial direction of thin oil lubricant
Sliding bearing（By taking radial direction bearing shell as an example）.
Bearing body part primary structure has（Such as Fig. 1）：21st, top bearing shell 22, fuel door 23, hexagon-headed bolt 24, cylinder
Pin 25, bearing cap 26, pin 27, oil level indicator 28, oil sealing cap 29, oil seal ring 30, the cooling chamber cap 32 of bearing block 31 get rid of oil
The lower bearing of ring 33.
Pump is during operation, and pump shaft drives the disc being enclosed on the diameter of axle to rotate, and disc is immersed in oil using bottom
The lubricating oil inside bearing chamber is brought up to bearing shell lubrication up and down in pond.Bearing can constantly consume during work
Certain lubricating oil is damaged, client can borrow oil level indicator it can be seen that whether Bearing inner needs to refuel, and then turns on turret head
Bolt, takes away fuel door.Drain the hot gas inside bearing chamber, refueled by oil level indicator.So as to ensure that the safety of bearing can
By operation.
Pump is during operation is rotated, meeting frictional heat between bearing shell and pump shaft, and the temperature of lubricating oil also can be with upper
Rise, although having cooling chamber in bearing body structure design, partial heat can only be taken away, pump body still has part hot gas,
Air relief cock is fitted without on existing structure, hot gas can not be excluded so that the pressure inside the pressure and oil level indicator of Bearing inner is very
Hardly possible forms pressure differential, and the oil level inside oil level indicator will not also change in succession, cause bearing body internal lubrication oil oil mass without
Method is known.So result in, bearing shell pump operation for a period of time after, because lubricating oil is reduced, bearing shell do not moistened preferably
Sliding and cooling, dry friction, locking causes pump not run on pump shaft, or bearing bush abrasion is serious, is shaken so that pump is produced in succession
The problems such as dynamic, noise.
Utility model content
The purpose of this utility model is（One）By changing fuel door structure, it is not necessary to which extra increase is vented zero again
Part, so as to reduce cost；（Two）Once refuel in place, need not be refueled again by dismounting fuel door afterwards, allow the operation of oiling
Simplify；（Three）By improved structure, can more timely discovery oil mass, preferably exclude hot gas, preferably protect bearing shell,
Increase the service life of pump.So that the more safe and reliable operation of pump more function.The utility model design improves thin oil profit
The horizontal multi-stage pump bearing bracket of sliding fuel door, including top bearing shell, fuel door, hexagon-headed bolt, straight pin, bearing cap, pin, oil level
Meter, oil sealing cap, oil seal ring, bearing block, cooling chamber cap, disc, lower bearing, pump shaft, it is characterised in that：Pump shaft by top bearing shell and
Lower bearing is arranged on bearing block, and disc is set with pump shaft, and cooling chamber and cooling chamber cap are provided with bearing block bottom,
Bearing block top is provided with fuel door, fuel door is fixed on bearing block by hexagon-headed bolt, in hexagon-headed bolt top with
One straight pin is mutually pushed up, and straight pin is located in top bearing shell positioning hole, and pump shaft and bearing block junction are provided with oil sealing cap and oil sealing
Circle；Fuel door bottom is relative with the perforate on bearing block, and air bleed slot is offered in fuel door.Described fuel door with bearing
The relative place of perforate on seat is an inner groovy, and air bleed slot is opened in bottom insertion inner groovy and the outside of fuel door of fuel door
Edge.The heat that advantage of the present utility model is produced when pump in operation type, bearing, the cooled water in part is taken away, partly with heat
Gas is discharged with the air bleed slot in fuel door.Then oil level indicator utilizes the function of itself, and the change of oil level is found in time, passes through oil
Cup is refueled.Certainly, there is this new construction, subsequently refuel without hex bolts is turned on again, pull down fuel door.But it is straight
Connected lubricating cup to be refueled, to keep fuel tank internal oil level constant.Bearing shell is allowed to have constant, a good ground lubrication and cold
But environment, so as to increase the life-span of pump.Allow pump safe and reliable operation.

Embodiment
The horizontal multi-stage pump bearing bracket of thin oil lubricant fuel door, including top bearing shell, fuel door, turret head spiral shell are improved in figure
Bolt, straight pin, bearing cap, pin, oil level indicator, oil sealing cap, oil seal ring, bearing block, cooling chamber cap, disc, lower bearing, pump shaft,
It is characterized in that：Pump shaft is arranged on bearing block by top bearing shell and lower bearing, disc is set with pump shaft, under bearing block
Portion is provided with cooling chamber and cooling chamber cap, bearing block top is provided with fuel door, fuel door is fixed on axle by hexagon-headed bolt
In bearing, top is mutually pushed up with a straight pin in hexagon-headed bolt, and straight pin is located in top bearing shell positioning hole, in pump shaft and bearing block
Junction is provided with oil sealing cap and oil seal ring；Fuel door bottom is relative with the perforate on bearing block, offers and puts in fuel door
Air drain.Described fuel door is an inner groovy at the relative place with the perforate on bearing block, and air bleed slot is opened in the bottom of fuel door
The outer ledge of portion's insertion inner groovy and fuel door.
The utility model processes an air bleed slot, wide 3 millimeters of 5 millimeters deep on the basis of original fuel door.So when pump exists
Operation type, the heat that bearing is produced, the cooled water in part is taken away, partly with hot gas as the air bleed slot in fuel door is discharged.
Then oil level indicator utilizes the function of itself, and the change of oil level is found in time, is refueled by lubricating cup.Certainly, have this new
Structure, subsequently refuels without hex bolts is turned on again, pulls down fuel door.But directly refueled by lubricating cup, to keep
Fuel tank internal oil level is constant.Bearing shell is allowed to have constant, good ground lubrication and a cooler environment, so as to increase the life-span of pump.
Allow pump safe and reliable operation.
