Starting of drill rod of hydraulic cylinder    

Hydraulic breaker (hammer) installation, so that the digging machine in the municipal construction, maintenance and construction of the effective crushing of concrete pavement and clearing floating large stones. The criterion of selecting hydraulic breaker is to choose the most suitable hydraulic breaker according to the operation stability of the backhoe loader, the task pressure of the hydraulic circuit installation and the power consumption. Prior to this, we should carefully read the interpretation of the use of digging machine products, or to our company's relevant departments for indirect technical advice.

1. Browse the operation manual of hydraulic breaker, avoid breaking hydraulic cylinder and digging machine hydraulic cylinder, and operate them effectively.

2 before operation, review of bolt and the connector is loose, and the hydraulic pipeline leaks scene.

3, don't use hydraulic breakers to pick holes in strong rocks.

4, not in the hydraulic cylinder piston rod full extension or full contraction under the condition of the operation of the crusher.

5. When the hydraulic hose emerges strong vibration, the operation of the crusher should be stopped, and the pressure of accumulator will be reviewed.

6. Avoid the interference between the boom of the backhoe loader and the drill bit of the crusher.

7. Except the drill rod, don't immerse the breaker in the water.

8, the crusher can not be used as lifting appliances.

9, not in the backhoe loader tire side operation crusher, bicycle high-grade tires.

10, hydraulic breaker and digging loader or other construction machinery installation connection, request task flow and pressure must meet the technical parameters of the hydraulic breaker host hydraulic system, hydraulic breaker "P" port and the main low-voltage circuit connection, "0" and the main return circuit connection machine.

11, hydraulic breaker task of the best hydraulic oil temperature is 50 - 60 degrees, the highest shall not exceed 80 degrees hydraulic cylinder. Otherwise, the load of hydraulic breaker should be increased.

12, hydraulic breaker using the task medium, usually can be consistent with the main hydraulic system oil. Some areas recommend using YB - N46 or YB - N68 anti-wear hydraulic oil, cold area using YC - N46 or YC-N68 low temperature hydraulic oil. The filtration accuracy of hydraulic oil is not less than 50 m.

14. The new and repaired hydraulic breaker must be charged with new nitrogen, the pressure is 2.5, + 0.5MPa.

Between the 15 and the drill shank and the cylinder guide sleeve must use calcium base grease or composite calcium base grease was smooth, and each class is the class with a.

16, hydraulic breaker task must first press the drill rod on the rock hydraulic cylinder, and maintain the pressure after the start of the hammer, not allowed to start in the suspended state.

17, do not permit the hydraulic breaker when using the crowbar, lest the broken drill rod.

18, the use of hydraulic breaking hammer and towing mast should be perpendicular to the face, not to occur as the criterion of radial force.

19, the broken object has emerged breaking or beginning of cracks, should immediately stop the impact of the crusher, so as to avoid the emergence of harmful "empty play"".

20, hydraulic breaker to temporary stagnation when use should be placed as far as nitrogen, and the oil inlet and outlet seal, do not shun below -20 in low temperature environment. The wishes mentioned above can support the users and make our machines better
