LA11V0 Axial piston variable pump
The plunger pump is a type of reciprocating pump, belonging to the volumetric pump. Its plunger is driven by the eccentric rotation of the pump shaft and reciprocates. Its suction and discharge valves are both one-way valves. When the plunger is pulled outward, the pressure in the working chamber decreases, the outlet valve is closed, and when it is lower than the inlet pressure, the inlet valve opens and liquid enters; when the plunger is pushed inward, the pressure in the working chamber increases, the inlet valve closes, and when it is higher than the outlet pressure, the outlet valve opens and liquid is discharged.
The variable stroke is very short. And the variable mechanism is designed for high-pressure operation and is controlled by a control valve. Therefore, the pump has a fast response speed. The radial structure design overcomes the problem of axial piston pump slipper eccentric wear. Its impact resistance is greatly improved.
The hydraulic piston pump relies on the hydraulic oil tank for oil supply by air pressure. After each start of the machine, the hydraulic oil tank must reach the use of air pressure before the machine can be operated. The straight-axis slant plate piston pump is divided into two types: pressure supply type and self-priming type. Most pressure supply type hydraulic pumps use oil tanks with air pressure, and some hydraulic pumps themselves have oil replenishment sub-pumps to provide pressure oil to the oil inlet of the hydraulic pump. The self-priming oil type hydraulic pump has a strong self-priming ability and does not require external force to supply oil.

Q1: What is the delivery date after an order is placed?
A: It depends on whether the products you buy are in stock. If we have inventory, we can arrange shipment in 2 to 3 days. If not, the delivery time is determined by the production time of the factory.
Q2: If the products do not meet the requirements, how to solve the problem?
A: If the products do not conform to the customer's samples or have quality problems, our company will be responsible.
Q3: How to calculate torque?
A: The calculation formula is as follows:
Torque (Nm) = Displacement (cc/rev) x Working Pressure (MPa) x 0.16 (Factor)
According to the functional theorem: Vm (ml per radian) × w (radian per second) × p (MPa, differential pressure) × (total hydraulic motor efficiency) = w (radian per second) × T (Nm); so T =Vm×P×η; where the milliliter per radian of Vm is converted into milliliter per revolution and needs to be divided by 2π, which is multiplied by 0.16.
The displacement can be seen from the product label. The working pressure depends on the pressure gauge at the entrance of the orbit hydraulic motor. Knowing these two values, you can calculate the output torque of the orbit hydraulic motor at this time.
Q4: What kind of Motor circuit is there?
A: Hydraulic motor circuit has series and parallel connection.
