How To Solve Normal Problems Of Scissor Lift Table

The lift table has been subjected to rigorous quality testing before leaving the factory, but it is necessary to maintain wear and maintenance between the parts after long-term use, as well as regular maintenance and repair. The following is a simple methods summary of thehydraulic lift table that often appear .

First part, the lift table when the use of lifting or unable to rise.

Reason and exclusion method:

1,reason: overload

Exclusion method: to reduce the load

2,reason: return valve is not closed

Exclusion method: tighten the return valve

3,the reasons: manual pump check valve stuck, return failure

Remedy: Unscrew the pump port bolts, repair, clean, replace the cleaning of hydraulic oil

4,the reasons: manual pump, gear pump serious oil spill

Remedy: Replace the pump seal

5,the reasons: gear pump damage, hit the oil without pressure

Remedy: Replace gear pump

6,the reasons: lack of hydraulic oil

Exclusion method: fill the hydraulic oil

7.Reason: circuit breaker

Exclusion method: check button contactors and fuses

8.     Reason: filter clogged

Exclusion method: replacement or cleaning

9.     reasons: support valve or solenoid valve failure, there are two cases: A, electromagnetic coil input voltage less than 220V. B, the electromagnetic coil burned C, spool stuck

Exclusion method: repair or replacement

Second part: lift down by itself during use

Reason and exclusion method

1,reason: check valve discharge

Remedy: Check the check valve in the group. If the check valve is found to have dirt on the check valve. Cleaning check valve.

2.  the reasons: the valve closed lax

Remedy: Check whether the drop valve has electricity, such as no electricity to exclude the drop valve itself or replace the down valve. The poppet valve of the poppet valve must be kept clean and flexible.

3. the reasons: the cylinder leak

Remedy: Replace the cylinder seal

Third part: lift the use of the process does not decline

1,Reason: Falling valve failure

Remedy: Check if the drop valve is energized when the drop button is pressed. If there is no electricity, try to rule out; if there is electricity, then remove the drop valve itself failure, or replace the drop valve. The falling spool should be kept clean and lubricated.

2,the reasons: the decline in speed control valve offset

Remedy: Adjust the descending speed control valve, if the adjustment is invalid Replace the new valve.When we meet some potential problems of lift table, we could use the above solutions to solve the problem.
