The utility model comprises filler opening, oil outlet, pump case, blade, leaf spring, impeller, impeller shaft, left pump cover, right pump cover; Impeller center and pump case lumen centers arranged off-centre have formed volume by the little oil pocket that diminishes gradually more greatly that becomes gradually, and the size of offset is relevant with the pressure of pump and flow; Lubricant oil sucks from filler opening, gradually reduce into high pressure oil in oil pocket, discharge from oil outlet, blade is pressed on the surface of internal cavity of pump case tightly by the thrust of the leaf spring in centrifugal force and the groove, play the effect of sealing, the central position of blade is fixed by impeller shaft.
Be provided with filler opening, oil outlet on the right pump cover, have oil suction chamber on the surface of right pump cover and pump case sealing surface one side and go out oil pocket, as the runner that lubricant oil sucks and discharges, oil suction chamber and go out oil pocket and be communicated with filler opening, oil outlet respectively.
On left pump cover, have the oilhole I with oil suction chamber (low pressure oil pocket) corresponding part, and go out oil pocket (high-voltage oil cavity) corresponding part and have oilhole II and oilhole III.Have valve opening on the left pump cover, spring, spool, paraffin temp controller and sealing screw are housed in the valve opening successively, the common on-off valve that forms with temperature control.On-off valve is driven by the paraffin temp controller.High pressure oil in the lubricating pump enters around the cylindrical shell of paraffin temp controller through the oilhole III, and the paraffin perception oil temperature in the cylindrical shell realizes function of temperature control.Under the normal temperature, on-off valve is connected, and the oil outlet place has sub-fraction lubricant oil to be back to filler opening, and the oil mass of discharge is reduced.When oil temperature surpassed setting value, the paraffin temp controller promoted spool and moves, and on-off valve is closed, and cut off oil outlet to the oil circuit of filler opening, made to discharge the oil mass increase.Satisfied the diesel lubrication cooling requirement that temperature rising, oil mass strengthen.
Described paraffin temp controller is comprised of plunger, seal ring, paraffin, cylindrical shell, end cap.Paraffin is encapsulated in the cylindrical shell, and end cap is fixed on the cylindrical shell, and plunger runs through the central through bore on the end cap, and seals by seal ring with end cap.When temperature raise, paraffin expanded, and outwards promotes plunger, and plunger promotes spool and moves, and when temperature reduced, paraffin shrank, and relied on spring thrust, made spool move inside promotion plunger.
Described oil suction chamber is the low pressure oil pocket; Going out oil pocket is high-voltage oil cavity.
The beneficial effects of the utility model:
Diesel engines has many movement parts, such as bent axle, connecting rod, piston, distribution device, oil feeding mechanism etc.They not only need to lubricate, and the heat that produces by the lubrication friction in pairs and cylinder combustion transmits.The quality of lubricated and cooling effect directly has influence on complete machine power character, Economy and the functional reliability of diesel engine.In the lubricating system of diesel oil engine that generally uses at present, lubricating pump is driven by bent axle, and along with diesel engine speed raises, the lubricating pump rotating speed increases, and fuel delivery strengthens.The fuel delivery of lubricating pump is only relevant with rotating speed, and is irrelevant with the oil temperature of lubricant oil.In fact, under the same rotating speed of diesel engine, when load increased, heating value strengthened, and needed larger lubricant oil fuel delivery, to strengthen the cooling of heating part.Therefore, the temperature control variable lubricating pump that the utility model provides, having solved oil mass can not raise and the problem of increase along with oil temperature, has great importance to improving diesel engine performance and reliability, and economic and social benefit is obvious.
