Features:
The HDY series hydraulic hammer, which matches the E and D series
power stations, is the latest energy-saving and environmentally
friendly foundation construction equipment developed by our
company. It adopts multiple advanced hydraulic and electrical
control technologies, with characteristics such as low noise, no
pollution, high efficiency and energy saving, safety and
reliability, and easy operation. Suitable for hammering
construction of prefabricated pipe piles and steel pipe piles with
different geological conditions and requirements, the D550 power
station can also be matched with vibration hammers for
construction, making it an ideal new generation of piling
machinery.
The hydraulic system has high efficiency, with a rated working
current of about 200~250A, and can be equipped with 120~150 square
aluminum cables.
The cable has a small cross-sectional area and is lightweight,
greatly reducing the labor intensity of workers; HDY25 hydraulic
hammer is equipped with Dongfeng Cummins QSZ13-C550 diesel engine,
two Rexroth A11VLO260 plunger pumps and one Parker T67DB double
blade pump connected in series to form a pump set, providing
surging power for construction;
Adopting the international first-class brand Rexroth main oil pump
and valve, with good stability, high reliability, and high
efficiency and energy saving;
Adopting the international first-class brand Hedeke oil return
filter, with high flow rate, high filtration accuracy, and low oil
return resistance, it can
effectively improve the cleanliness of the system oil, reduce
equipment failure rate, and extend equipment service life;
The hydraulic cylinder of the pile driver adopts international
first-class brand Trelleborg seals, which have low failure rate,
high efficiency, and long service life;
Adopting a high-power three in one oil cooler, coupled with a
temperature controller to accurately control the oil temperature,
completely solves the problem of high oil temperature in hydraulic
pile driving, significantly improves pile driving efficiency, and
effectively extends the service life of seals and hydraulic oil;
The power station adopts a high-level fuel tank and internal forced
ventilation design to improve oil pump suction, oil pump motor,
electrical cabinet or engine heat dissipation.
Main Structure and Appearance:
The HDY series hydraulic hammer is composed of mechanical parts,
hydraulic system, and electrical system. The mechanical part is the
main body of the hydraulic hammer, which performs external work on
the hammer. The hydraulic system is the power source of the
hydraulic hammer, while the electrical system is the energy input
and control center of the hydraulic system.
The mechanical part consists of the hammer core assembly, hammer
body assembly, oil cylinder assembly, upper pile cap, lower pile
cap, hammer pad, pile cap buffer ring, landing gear, etc. The
landing gear is used for the ascent and descent of hydraulic
hammers; The hammer body is the supporting body of the entire
mechanical part, used to support the oil cylinder and hammer core;
The upper pile cap is fixed at the bottom of the hammer body, and
the lower pile cap is sleeved inside the upper pile cap to support
the pipe pile and transmit the impact force; The hammer pad and
pile cap buffer ring are fitted onto the lower pile cap to achieve
energy transfer between the hammer core and the pipe pile; The oil
cylinder assembly of the hydraulic hammer achieves the lifting of
the oil cylinder piston and the acceleration of gravity through the
opening and closing of the plug-in valve installed on the valve
block of the oil cylinder. The opening and closing of the plug in
valve is controlled by the solenoid valve and sequence valve
installed on the valve block of the oil cylinder.
The hydraulic system mainly consists of a power station, oil pipes,
oil cylinders, etc.
The electrical system mainly consists of four parts: controller,
electronic control box, sensors, and engine.
