Diesel Engine Piston CAT 324-7382 265-1401 C9 Aluminum E336D/E330D

The Working Principle Of The Plunger Pump:

When the engine drives the transmission shaft to rotate, the connecting rod pushes the plunger to reciprocate in the cylinder block, and at the same time, the side of the connecting rod drives the piston to rotate together with the cylinder block, and the oil distribution plate is fixed. When working, under the action of the cam and the plunger spring, the plunger moves up and down repeatedly to complete the oil pumping task. When the convex part of the cam is turned, the plunger moves downward under the action of the plunger spring, and the upper part of the plunger is the pump oil chamber to generate a vacuum. At this time, the oil inlet on the plunger sleeve at the upper end of the plunger will be opened. The hydraulic oil in the oil passage of the oil pump enters the pump oil chamber through the oil inlet hole, the plunger moves to the bottom, and the oil inlet ends.

When the camshaft turns to the convex part of the cam to lift the rolling body, the plunger spring is compressed, the plunger moves upward, the hydraulic oil is pressurized, and part of it flows back to the upper body oil cavity through the oil hole. When the top surface of the plunger covers the oil inlet hole, the oil distribution chamber on the top of the plunger becomes a sealed space due to the small matching gap between the plunger and the cylinder liner, the plunger continues to rise, and the oil pressure in the pump oil chamber rises rapidly When the pump oil pressure is greater than the oil outlet spring, the hydraulic pump is pushed out, and the high-pressure liquid enters the oil cylinder through the main operating valve.

When the plunger is supplied with oil, it communicates with the chute on the plunger and the oil return hole on the cylinder liner, and the low-pressure oil path of the pump oil chamber is communicated with the middle hole and chute of the plunger head, the oil pressure drops, and the oil outlet valve Under the action of the spring, it is closed to stop the oil supply. The plunger continues to go up, and when the convex part of the cam turns over, under the action of the spring, the plunger goes down again to start the next cycle.

When the excavator is not working, the main control valve is in the neutral position, and the high-pressure oil passes through the neutral position of the main operating valve, and returns to the oil under the load-sensitive control, part of the control pump continues to work, and part of it returns to the oil tank. My personal understanding is: the neutral position of the main control valve is a large oil return line.
