Product description
The hydraulic coupling reverse reducing gear box has the following structure features:
1. The
fixed guide speed-governing technology is used for the coupling reverse
reducing gear box, which is the first one in domestic. It is of the new
structure, sensitive and reliable in speed governing and clutch
control, and has its own features in system function and construction.
2. The
output shaft of the coupling reverse reducing gear box is located 425mm
above the center line of its input shaft and near the center height of
the mud pump input shaft, which the diesel coupling reverse set can be
connected directly with the mud pump through a universal coupling.
3. The coupling reverse gear box has one group of gears less than coupling ahead gear box, with about 1% higher transmission efficiency.
4. The lubricating system of coupling reverse gear box has been modified so as to meet the lubricating requirement of the bearing train with the working cavity of coupling reverse gear box being fully drained off .

The power capacity of the coupling reverse gear box is shown in Figure 1.1. The model of coupling reduction gear box can be determined according to its input power P1(i.e. Diesel engine calibration power PC minus fan power PCF) and the input speed N1 of the coupling reducer (i.e. the diesel engine calibration speed C).
1) Decreasing torque operator characteristic curve
2) Constant torque operator characteristic curve
3) linear torque operator characteristic curve
4) Parabolic torque operator characteristic curve
5) Steep rise torque operator characteristic curve
Mode 1: Combined water cooling, flange connection
Combined
water cooling is used for the reverse reducing gear box. Its input end
is connected to diesel engine with an elastomeric coupling(3) and both
the coupling and engine are installed on the same common base(4), with
features of reliable performance, compact design and easy to be moved
and transported. It is the typical diesel coupling reverse set and also the main coupling reverse set recommended by our company.
Mode 2: Separate air cooling, independent mounting
The coupling reverse reducing gear box is separately air cooled and independently mounted on a separate
base (4). It is connected to diesel engine through the universal
coupling (3) and connected to mud pump input end with the universal
coupling (1). With the flexible mounting mode, it can be packaged with
different types and various models of prime movers, and is also suitable
for modification of the conventional matching system of mud pump set.
It only need to make a common skid according to site condition , connect
the coupling with engine and install them on the skid to form a module
unit for easy installation and transport.
We are a professional manufacturer and sales company of generator sets, engines and accessories.
Founded
in 2010, JiNan GuoHua Green Power Equipment Co.Ltd. covers an area of
5,000 square meters. Now as a generator sets company that incorporates
research and development, manufacture as well as sales, we have
established stable supply and marketing relationships with clients from
32 provinces and 20 countries.
Our main business:
Early period: consulting, design, supply and installation of engine power generation equipment, including diesel power generation, natural gas power generation, coal gas power generation, biogas power generation, hydrogen Generator and parts.
Mid-period: supply generator and engine accessories. GUOHUA has two warehouses. One is located in ShanDong province and mainly supplies the domestic North, South markets and foreign. The other is located in XinJiang province and mainly supplies the western market, which allows fast delivery and quality assurance.
Later period: The company also provides engine overhaul and maintenance services with experienced engineers and professional skills. Traces of ours can be seen not only in China, but also in Ghana, Kazakhstan, Vietnam and Myanmar.
1. Easy installation, diesel engine coupling unit and drilling pump can be respectively integrated lifting.
2. Compared with the traditional single pump group configuration, the belt transmission is cancelled, avoiding the malady of adjusting belt string tightness due to belt stretching.
3. With clutch function. When the diesel engine does not stop, and at any speed, through the coupling of oil filling and oil discharge, can be without any impact and wear, smooth clutch, can replace the air bag clutch, simplify the transmission parts.
