GENERAL

HYDROKRAFT axial piston pumps and motors operate on the swashplate principle.  The pistons are fitted with shoes, which are held against the swashplate.  All pressure loaded parts, such as the valve plate and piston shoes are hydraulically balanced.  The displacement of all variable units can be adjusted mechanically, hydraulically or electro-hydraulically.

Operation

The hydraulic system should be started up and tested according to the following instructions.

1.

All non-essential personnel should leave the operating area.

2.

Fill the hydraulic reservoir with fluid that has been filtered to ISO code 16/13.

3.

Fill the pump and motor cases with fluid that has been filtered to ISO code 16/13.

4.

Open all suction line valves.

5.

Put the pump displacement control in neutral.

6.

Jog all electric motors to verify direction of rotation.

7.

Start the main pump and let it operate for 5 minutes in neutral.

8.

Bleed air from the main circuit at the highest point in the system while the main pump is operating in neutral.

9.

Adjust the main pump displacement control to 10% of full stroke and let it operate unloaded in the forward direction for 10 minutes.

10.

Repeat step 9 for the reverse direction.

11.

Check the reservoir fluid level.  If fluid needs to be added, shut down the drive and replenish with fluid filtered to ISO code 16/13.

12.

Check all filter condition indicators.  If filters need to be replaced, shut down the drive and perform the replacement.

13.

Check the hydraulic system for leaks.  If leaks are present, shut down the drive and tighten the connections.

14.

Perform a full functional test.  At this time, operating speed of the drive should be adjusted so that operating pressures can be monitored and compared to expected values.

15.

Listen for unusual noise and look for jerky machine movement.  These observations may indicate that additional air bleeding is necessary.

16.

Monitor hydraulic reservoir temperature at all times.  If the reservoir temperature exceeds 120F, verify that the heat exchanger is operational.

17.

Shut down the drive.

18.

Record all hydraulic system settings in a maintenance log.

19.

The drive is now ready for full operation.

Maintenance

1.

Prepare a maintenance log for each hydraulic drive so that inspections can be planned and service work performed at regular intervals.

2.

After the hydraulic drive has been commissioned for operation, it must receive periodic maintenance.  The extent and frequency of the periodic maintenance will depend on the equipment and severity of duty.

3.

Basic maintenance should be based on the following schedule.

Daily

After 100 Hours

After 3 Months

Every 6 Months

Every 12 Months
