Vibratory pile driver winter maintenance tips
The concentration of the gear oil should not be too high, it should be reduced as much as possible. It is best to mix it with the oil and then add.
The second-order vibration is only suitable for about 10 seconds. Generally, the hard soil can be used this vibration force. It could not hit too hard, this will easily cause high temperature to the box, causing damage to the bearing. The worse is to destroy the eccentric gear group. The seal must be preheated before working at -40 °C.
Because the working environment of the pile driver is generally bad, it is easy to cause problem. In order to eliminate the hidden troubles and shorten the maintenance period, it is necessary to carry out daily and regular maintenance

2, Regular maintenance
Regularly clean the tank and replace the hydraulic oil. The running-in period lasts for 500 hours, the second time is after three months, third time is in the ninth month. The replacement time should be subject to availability.
Regular maintenance of vibratory pile driver
3. Use and maintenance during the running-in period.
1) The vibratory pile driver starts works for 100 hours for the running-in period. It should be used carefully during the running-in period. The load should not be too large. The use of the running-in period will have a great impact on the service life of the machine.
2) After 50 hours of operation, check that the cleanliness index of the hydraulic oil is not lower than 18/15. At the same time, check and clean the oil inlet and return oil filter, cleaning or replacing every 200 hours, pay attention to the inspection. , rubber or asbestos gasket is not damaged, if it is damaged, it should be replaced in time.
