Analysis on the application and repair method of hydraulic hammer of highway guardrail piling machine
January 18, 2019
In the process of highway construction, Highway guardrail drilling machine has become an essential drilling thing, drilling machine is divided into automatic drilling machine and semi-automatic drilling machine two kinds. With the gradual addition of human resources costs, most enterprises are considering automatic drilling machine as the development of the policy and direction.
In order to take the automatic drilling machine as the development of the policy and direction, we must first understand the drilling machine drilling common sense. Drilling is the use of drill bits on the solid material for processing out of the hole operation, including a variety of parts of the hole processing, to remove part of the car, boring and milling, and so on, a large part of the fitter using drilling machine and drill bit, hole expansion drill and reamer and other drilling things to end. Usually in the drilling machine drilling time, the drill should end two movements together, that is, the main movement and auxiliary movement. The main motion refers to the rotational motion of the drill bit around the axis, also known as the cutting motion, while the auxiliary motion refers to the linear motion of the drill bit along the axis direction to the workpiece, also known as the motion.
In the drilling time, mainly because of the bit structure of the defects, affecting the quality of processing, processing accuracy is generally below the IT10 level, the appearance roughness of ra12.5μm around, attributed to roughing.
These are the common knowledge of drilling machine for highway guardrail, which is brought to us by Tengzhong machinery. A brief talk on the drilling common sense of highway guardrail drilling machine We hope to help us to understand the drilling machine more deeply. In the highway guardrail piling machine hydraulic hammer application process, will inevitably occur a lot of heat, but to ensure that the high-speed 佁 guardrail piling machine hydraulic hammer normal operation, in addition to using the machine oil pump to the piston injection oil forced smooth, but also necessary in accordance with the requirements of the product specification,
One hours per operation to the piston artificial participation in molybdenum disulfide lithium base grease smooth. The main effect of participating in disulfide conjecture molybdenum lithium base grease is to reduce the conflict force between the lower cylinder and the upper piston, to improve the sealing function of the piston and cylinder, and to play the effect of heat dissipation. If you can persist in doing these three points, you can use the extension of the life of the pile hammer.
In addition, we should also understand the highway guardrail piling machine hydraulic hammer repair and elimination measures. Remove the check valve from the bottom of the pump body of the fuel pump and remove the injector, view and clean the valve parts, if found that the core seat is wearing a wear condition, should be immediately replaced. In the process of using the pile hammer of the guardrail piling machine, the fault caused by the injector makes the diesel hammer not be able to carry out the operation normally more, the main reason is that the upper piston in the reciprocating movement of the time, and the upper cylinder is in relative conflict, it is inevitable that a certain amount of metal powder will occur.
And these powders are very simple to carry out the injector of the plunger, so that the occurrence of internal leakage, from the oil pump to the nozzle between the tubing force analysis of the highway guardrail piling machine hydraulic hammer application and repair methods can not be set up, piling hammer will not be able to operate normally. Therefore, if the nozzle can be cleaned regularly, it can be useful to prevent leakage and blockage in the injector, to ensure the normal operation of the pile hammer. In addition, when adding fuel, because the refueling container contains moisture, so that the water mixed into the fuel tank, the formation of diesel hammer operation is not normal.
