In the process of railway workers using the rail stretcher, there are inevitably some small failures. After that, the machine will no longer be used to avoid accidental injury to staff. In order to understand the troubleshooting methods of machines when railway workers encounter small faults, the small compilation of railway track equipment has developed troubleshooting methods for railway workers. Let's have a look!

The hydraulic rail stretcher is a kind of equipment suitable for the stress release  long rail laying of 75kg / M  60kg / M seamless rail. In the field construction, when the rail temperature is lower than the rail locking temperature within a certain range, the rail under zero stress state is forcibly stretched to the length of the locked rail temperature by the rail stretcher,  then locked again.

The faults of the railway stretcher  the troubleshooting methods are as follows:

Fault one: what should I do if the oil cylinder doesn't work  crawls.

Causes  Troubleshooting:

1. The piston seal ring is faulty. Troubleshooting: replace the sealing ring.

2. The piston  cylinder liner are seriously worn  the clearance is too large. Troubleshooting: replacing new parts.

3. The hydraulic oil is  clean  the cylinder liner has groove marks. Troubleshooting: replacing new parts.

4. The oil pipe joint is blocked. Troubleshooting: clean  replace new parts.

5. The pump plunger  pump sleeve of the pump station are seriously worn  the clearance is too large. Troubleshooting: replacing new parts.

6. The plunger return spring of the pump station is invalid  broken. Troubleshooting: replacing new parts.

7. The oil suction port of the pump station is blocked. Troubleshooting: clean up sundries.

8. Leakage of all joints. Troubleshooting: retightening

Problem 2: if the stretcher can't lift the rail, what should I do?

Failure cause: excessive wear of inclined iron teeth

Troubleshooting: repair  replace angle iron with angle grinder.

Fault 3: running rail  inclined rail

Cause of failure: severe overload  fatigue deformation of inclined iron seat.

Troubleshooting: replacing

The above is a summary of the railway stretcher faults  troubleshooting methods for you, hoping to help you. If you need to purchase railway track equipment, you can go to Sichuan Xinda Rail Transit Equipment Co., Ltd. to purchase qualified products.
