Product description

BMER Orbit Hydraulic Motor is an end face oil distribution type orbit hydraulic motor.

The displacement range is from 100cc/r to 750cc/r for selection. It can meet the requirements of various equipment speeds and torques.

The character of BMER Orbit Hydraulic Motor are as follows:

1. Roller type stator rotor pair structure, rotor cycloid contour modification technology, with low starting pressure and high efficiency.

2. Years of experience in processing and manufacturing, Integrate the port plate and valve plate into one. More compact structure and higher efficiency.

3. The application of balance plates ensures the stability of the motor at low speeds, thus being able to withstand high hydraulic pressure.

4. The motor output shaft is supported by imported heavy-duty tapered roller bearings,

Strong ability to withstand axial and radial loads which make the motor more durable.

5. The motor adopts a high-pressure shaft seal, Allow shell pressure up to 175 bar, No need for external leakage oil pipe from the casing. When using the outer leakage pipe of the casing, Allow shell pressure up to 200 bar.

This series of motors include:

Standard motor connection form/Wheel connection form/

Structural design such as connection form of Aerial work truck.

With Various connection forms, it can replace corresponding products in China, Europe and America, and customers have a wider range of choices when selecting products.

Precautions when using are as follows:

1. A simultaneous maximum torque and maximum speed NOT recommended.

2. Recommended Maximum System Operating Temp. is 82°C [180°F].

3. Intermittent Operation – under 10% of every minute.

Advantages of connecting the outer leakage oil pipe of the casing:

1. Pollution control (Flushing motor housing).

2. The oil discharged from the cooling system dissipates heat from the motor, which will extend the service life of the motor.

FAQ

Q: 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.

Q: 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.

Q: 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.

Q: What kind of Motor circuit is there?

A: Hydraulic motor circuit has series and parallel connection.
