What are the main types of pile drivers?
And fuel injection, explosion, shock, ventilation and other work. The work is to rely on diesel hammer compression ignition diesel to start, it is necessary to ensure the cylinder seal The gas reaches a certain compression ratio, sometimes piling in soft soil layer is often because the reaction is too small, the amount of compression is not sufficient to ignite the initiation, you need to use multiple hook lift hammer decoupling impact, to start. The hammer seat diesel hammer with a fuel injection pump, fuel tank, cooling water tank and the pile cap. Play between the piston and the cylinder with elastic piston ring seal.x0d four hydraulic hammer x0d diesel oil to start with, the pressure into motivation, according to different soil hydraulic impact force to achieve the adjustment, the appropriate piling, is a new type of piling machine. Small and medium sized hydraulic piling machine, piling commonly used in the highway guardrail, highway guardrail construction. Similar piling equipment: hydraulic piling machine, highway guardrail, piling machine, piling machine road drill.
The market is the piling machine of many kinds, small as you introduced under the following four types: x0d, x0d drop hammer pile driver pile hammer is a heavy piece of steel, by using the hook lifting winch, after decoupling along the guide frame free fall and piling.x0d two, steamhammer piling machine x0d pile hammer comprises a hammer head and a hammer base., with steam or compressed air as a driving force, a single acting hammer and double acting hammer two. Single action piston or cylinder as the hammer to hammer, steam driven hammer up, then let the hammer seat along the guide rod fall and piling. Double acting steam hammer is increased as the piston hammer head with cylinder as hammer, steam driven hammer up, then drive the downward impact hammer. Piling up and down reciprocating speed, high frequency, vibration of the pile penetration stratum, can reduce the friction resistance, pile hammer effect. Differential two-way unequal force, the hammer seat has light weight, Effect of impact weight can be relatively increased, the performance is better. The hammer into the exhaust valve reversing by manual control, can also be installed in the side with the hammer and hammer lifting flange lever automatic control, impact stroke can be adjusted in two ways.
In three, diesel hammer hammer x0d is composed of a cylinder body and a plunger piston which is similar to the working principle and the single cylinder two stroke diesel engine into the cylinder combustion under high temperature and high pressure atomized diesel combustion chamber by injection pressure generated by the detonation driven hammer. Diesel hammer according to its structural form, rod and tube type. Guide rod type diesel hammer for hammer pressure in the plunger seat the pile cap, the cylinder for hammer along two guide rods. The lifting pile, the pile hanging in place pile frame in Longmen, then put the diesel hammer at the top of the pile, the hook will lift down the cylinder, and the cylinder sleeve let off hook falling into the plunger, will be closed in the steam The in cylinder air compression cylinder rocker pin until the pressure continues to fall outside the cylinder pushing hammer seat fuel pump, fuel pump will be injected into the cylinder oil mist, oil mist meet high temperature gas burning immediately above, blasting, explosive shock down make the pile sinking, to the top push the cylinder cylinder to be picked up, to fall along the guide rod, and the beginning of the second cycle. The impact of diesel hammer to hammer cylinder as the base, and directly with the lengthened cylinder wall direction, eliminating the two guide rods, the plunger is movable under the hammer in the cylinder. When the pile. The hammer seat at the lower part of the pile cap pressure at the top of the pile, lifting plunger with a hook, and then down from shock compressed in the cylinder in the closed air.
