F250 High-Pressure Plunger Pump
Product：
The complete set of 250 AK3 high-pressure plunger pump is maximum pressure is up to 280MPa. The liquid end (2800bar). The forced lubrication system of the power end solves the friction and overheating problem of long-term gear engaging. The domestic liquid end
(pressure below 1800bar) can be completely exchanged with American (Jetech) liquid end. Therefore, it can satisfy with pressure and flow rate requirements by only replacing liquid end, meanwhile, it solves the high cost issue of replacing parts as well. The "super simple maintenance " feature will benefit you a lot.
If the product is in demand, please confirm the proper pressure or flow in the table below and add into inquiry list.
Power end：
The electrical engine drives the high speed shaft through a pair of herringbone gears to transfer the torque to the crankshaft while reducing the speed. The crankshaft converts the rotating motion into reciprocating motion through the connecting rod mechanism, and the plunger is driven by the crosshead device to complete working cycles.
Liquid end：
When the plunger moves back under the driving crankshaft, the volume of the inner cavity of the pump gradually increases while the pressure decreases, then a negative pressure is formed, and the drain valve is closed. Due to the pressure difference, the inlet valve opens and the liquid enters into the working chamber. When the plunger continues to move to the return stroke limit position, the suction process is finished and the working chambers full filled with liquid. When the plunger moves forward, the working chamber volume gradually decreases while the pressure increases, the inlet valve closes and the drain valve opens, then the liquid is discharged from the discharge passage. When the plunger reaches the end point, the working chamber has the smallest volume and the largest pressure. The plunger continuously reciprocates, and the suction and discharge processes are alternately repeated, and the high pressure liquid is continuously discharged from the drain passage.
Cooling and lubrication system：
The gear oil pump runs with the high speed shaft, and the lubricating oil in the power end casing is sucked out to be cooled down through the heat exchanger, and then pass through the filter. The filtered low-temperature lubricating oil enters the crankshaft, bearing bush and other parts that need lubrication. The excess lubricating oil passes through the check valve and returns to the power end casing.
There are characterized by compact structure, small size, light weight and high efficiency. The power end adopts forced lubrication. The high speed shaft and crankshaft are herringbone gear transmission, which is stable and reliable, reducing the friction coefficient, improving the lubrication performance, noise small.
