Product Description

Traditional single-stage pumps by the reducer of diesel engine, clutch and transmitte narrow V-Belt drive mud pump, huge volume, complex system, and only by adjusting the throttle valve regulating emissions of diesel engine cylinder liner or replace the pump and the pressure of the pump, however, mud pump cylinder liner change frequently, unfavorable also work long hours in the region of the diesel engine at low speed, The displacement and pressure of mud pump can only be adjusted in a limited range, which can not well meet the requirements of drilling technology.

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.
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.
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 .

1. Power capacity
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).
2. Output characteristics

1) Decreasing torque operator characteristic curve
2) Constant torque operator characteristic curve
3) linear torque operator characteristic curve

4) Parabolic torque operator characteristic curve
) Steep rise torque operator characteristic curve

Installation Instructions

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.

Speed Regulating Type Hydraulic Coupling Reverse Gear Box Yotfj750/875Mode 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.

Our Advantages

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.
