Pumps, Pumping Machines & Parts #6605468

- the total stroke l of plunger reciprocating motion is unchanged, which is determined by the lift of the cam. - the amount of oil supplied to the plunger in each cycle depends on the oil supply stroke, which is variable without the control of camshaft. - the starting time of oil supply does not change due to the change of oil supply journey. -rotating the plunger can change the end time of oil supply, thereby changing the amount of oil supply.

.

- axial piston pump designed with swashplate

- high reliability and long service life; - rated speed is 1800 min-1 or higher; - strengthened shafts and bearings. - pressure balanced for rotation and load components;

- integrated control pumps, filters and relief valves available. - wide range of applications due to "combination block" design;

- short response time.

axial piston variable displacement pump with swashplate structure used for hydrostatic transmission in open circuit.

.

swashplate axial plunger variable pump for closed circuit hydrostatic transmission.

flow rate is proportional to driving speed and displacement.

the flow rate increases from zero to its maximum with the swashplate swing angle.

the liquid flow direction can be changed smoothly by making the swashplate swing over the middle.

variable modes can be easily matched with different control and regulation systems.

the pump is equipped with two relief valves at the high-pressure oil side to protect the hydrostatic transmission (pump and motor) from overloading.

high pressure relief valve also functions as filing valve.

built-in auxiliary pumps are used as refueling pumps and control pumps.

the maximum filling pressure is limited by a built-in filling relief valve.

full series with built-in pressure shut-off valves.

.

- a4fo axial plunger fixed pump with swashplate structure for hydraulic driving in open circuit - flow is proportional to driving speed and displacement. - excellent oil absorption performance - very low operational noise - long service life - allow the use of combined pumps - axle drive for assembling other pumps

.

variable displacement axial piston pump designed with swashplate for hydraulic transmission in closed circuit.

flow is proportional to input speed and displacement.

the auxiliary pumps and all necessary control valves are integrated.
