Piling hammer manufacturers explain to you how to classify pile drivers


The driving force of pile hammer can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer, etc.

Steam hammer pile driver


The pile hammer is composed of high chromium alloy hammer head and hammer seat, driven by steam or air compression. There are two kinds of single acting steam hammer and double acting steam hammer. The single acting steam hammer uses the plunger pump or cylinder as the high chromium alloy hammer head. The steam driven high chromium alloy hammer head rises, and then it is allowed to fall along the guide rod of the hammer seat and pile the foundation. The double acting steam hammer usually uses the intensified plunger pump as the high chromium alloy hammer head and the cylinder as the hammer seat. The steam driven high chromium alloy hammer head is raised, and the diesel pile hammer manufacturer drives the high chromium alloy hammer head down the impact foundation. Up and down left and right reciprocating faster, high frequency, so that the pile into the geological structure of the vibration, can reduce friction, the foundation pile is easy to use. For the differential steam hammer with different transverse interaction forces, its hammer seat is very light, reasonable impact capacity, net weight relativity can be expanded, and its characteristics are stronger. The reversing of the inlet and exhaust rotary valve of the steam hammer can be controlled manually, or the automatic control system can be installed on one side of the high chromium alloy hammer head and along with the boss operating handle of the high chromium alloy hammer head elevator. The two methods can adjust the impact stroke arrangement of the steam hammer.

Drop hammer pile driver


The pile hammer is a steel weight block, which is raised by the crane with a lifting hook. After the hook is released, it will fall down along the guiding frame and pile the foundation.


Diesel hammer pile driver


The main body of behavior is composed of cylinder and plunger pump, and its principle is similar to that of single slot two-stroke diesel engine. The strong working pressure caused by deflagration of atomized diesel engine under high pressure and high temperature is used to drive the high chromium alloy hammer head to work. Diesel engine hammers are divided into guide rod type and cylinder type according to their structure. The piston pump is used as the hammer seat of the pilot bar diesel engine hammer, which is pressed on the pile cap, and the cylinder is high chromium alloy hammer head, which is lifted along two guide rods. When piling the foundation, firstly lift the pile to the gantry of the pile frame, then put the diesel engine hammer on the pile top, lower the lifting hook to hang the cylinder, and then loosen the lifting hook to let the cylinder drop into the plunger pump to reduce the enclosed gas in the cylinder, and the cylinder will fall again until the pin outside the engine cylinder pushes the remote rod of the high-pressure oil pump on the hammer seat When the oil mist is sprayed into the tank, the oil mist touches the high-temperature steam body around the ignition point, which immediately produces deflagration. The springing force makes the pile move downward and push upward to warm the cylinder. When the cylinder falls down along the guide rod again, it just starts to impact the circulating system again. The cylinder is used as the hammer seat for the cylinder hammer, and the extended cylinder liner inner cavity is immediately used for guiding, and two guide rods are omitted. The plunger pump is a high chromium alloy hammer head, which can exercise up and down and left and right in the cylinder. When the foundation is driven, the pile cap under the hammer seat is pressed on the top of the pile, and the plunger pump is raised with a lifting hook, and then the downward impact is decoupled to reduce the closed air in the cylinder. And carry out the whole process of oil pump, burst, impact, ventilation and so on. The work of diesel engine hammer is started by compression ignition diesel engine. Therefore, it is necessary to ensure that the closed steam body in the cylinder exceeds the necessary compression ratio. Sometimes, when piling on the foundation on the geological structure of soft foundation treatment, the Nonel can not be ignited because of the small recoil force and insufficient reduction. Therefore, the high chromium alloy hammer head must be hung with the lifting hook for several times to release the impact and start. The hammer seat of diesel engine hammer is attached with fuel injection pump, automobile fuel tank, water cooling water tank and pile cap. The main active gap between plunger pump and cylinder liner is sealed by malleable piston pump ring.


Hydraulic hammer pile driver


With the working pressure of compressor lubricating oil as the driving force, the hydraulic press can be adjusted according to the different geological structure and soil layers, and the foundation pile driving can be carried out with more than moderate impact force.
