LA4VSO Axial piston variable pump
Used for hydraulic drives in open loop ciruits.
TheLA4VSO Axial piston variable pump has a certain self-priming ability, but the self-priming height should not exceed 500mm, and it is strictly forbidden to install an oil filter on the suction pipe. The diameter of the suction pipe should not be less than the recommended value. In addition, the pump must be adjusted to full deflection when self-priming.
When the speed exceeds 1500rpm, it is advisable to use oil supply, and the oil supply pressure is about 0.7MPa. In an open system, the flow rate of the oil supply pump should be 130% of the pump, and in a closed system, the flow rate of the oil supply pump should be 35% of the pump.
Low noise, wide flow range, high pressure and high performance. Widely used in light industrial machinery (such as injection molding machines, hollow molding machines, die-casting machines, shoe machines, etc.). Forging machinery (such as pipe bending machines, hydraulic presses, bending machines, etc.). Metallurgical machinery, port machinery and other industries.
The capacity of the pump is in proportion to its rotating speedand displacement;the stepless adjustment of thedisplacement can be materialized by regulating the swivelangle of its swash plate.With through-shaft structure, able to form combinationpump;Position constraint return mechanism;Spherical flow distribution, the piston is inclined around theshaft;
Features:
Equipped with swivel angle indicator of swash plate;
Stepless variable displacement;
Excellent suction performance;
Rated working pressure of 35MPa,Fast control response;
Low noise;
Long lifespan;
Excellent power/weight ratio;Modular design;
The drive shaft is able to bear the axial and radial load;Optional installation position;lt can operate with HF fluid to lower the operating parameter.

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.
