Introduction of Diesel Hammer Pile Driver

Diesel engine hammers are divided into guide rod type and barrel type according to their structure. The guide rod type diesel engine hammer uses the plunger pump as the hammer seat to press on the pile cap, and uses the cylinder as the high chrome alloy hammer head to lift along the two guide rods.When the foundation is piling, the Diesel Hammer manufacturer first hoists the pile to the pile frame and the gantry for hoisting, and then puts the diesel hammer on the top of the pile, lowers the lifting hook to hang the cylinder, and loosens the lifting hook to let the cylinder fall into the sleeve. The plunger pump expands and shrinks the closed gas in the cylinder, and the cylinder descends again until the pressure pin outside the engine cylinder pushes the remote rod of the high-pressure oil pump on the hammer seat, and the high-pressure oil pump sprays the oil mist into the tank body. The oil mist hits the high-temperature vapor around the ignition point and immediately deflagrates. The bouncing force moves down the pile and pushes it upward to warm the cylinder. When the cylinder falls along the guide rod again, it starts to impact again. circulatory system.The cylinder type diesel engine hammer uses the cylinder as the hammer seat, and immediately uses the extended cylinder liner inner cavity for guidance, eliminating the need for two guide rods. The plunger pump is a high-chromium alloy hammer head, which can exercise up, down, left and right in the cylinder. . When the foundation is piling, 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 gas enclosed in the cylinder. And carry out oil pump, outbreak, impact, ventilation, etc.

The whole process of work. The diesel engine hammer is started by a compression ignition diesel engine, so it is necessary to ensure that the closed gas in the cylinder exceeds the necessary compression ratio. If the reduction amount is insufficient and the detonating tube cannot be ignited, it is necessary to use the lifting hook to hang the high-chromium alloy hammer several times to decouple the impact and start it. The hammer seat of the diesel engine hammer is equipped with a fuel injection pump, an automobile fuel tank, a water cooling water storage tank and a pile cap. The subject movement gap between the plunger pump and the cylinder liner is sealed with a ductile plunger pump ring.
