QJM Hydraulic motor Applicable scope:

QJM hydraulic motor can be combined with various hydraulic oil pumps, valves and hydraulic accessories Hydraulic transmission device , because it has taken various specific measures in the design concept, it can meet the working conditions of various machinery and equipment. This type Oil motor It has many advantages, such as light weight, small equipment volume, large range of speed change, stepwise variable, self opening and closing of mechanical equipment braking, good slow and stable performance, reliable operation, shock resistance, high efficiency, long service life, etc. It has been widely used in mining engineering construction, lifting and logistics transportation, heavy metallurgical industry, crude oil, coal mining Ship manufacturing, CNC machine tools, light industry injection molding, geological exploration and other relevant departments. It can also drive crawler walking, track wheel driving, various rotary lifting departments, survey drilling, belt conveying, material mixing equipment, ground segmentation, ship manufacturing promotion, plastic pre molding and other departments.

Main features of QJM hydraulic motor:

1. The rolling element of this type of oil motor is replaced by a steel ball Inner curve hydraulic motor More than 2 rollers and crossbeams are used, so the structure is simple, the operation is reliable, and the size and total weight are significantly reduced.

2. The operating inertia force is small, and the steel ball is firmly pinned, so this type of oil motor has been operating continuously under high rotating and impact loads.

3. There are few friction pairs, the force on the oil distribution shaft and rotor is balanced, the ball plug pair transmits force with the help of a ball pad made of self-lubricating composite material, and has the necessary conditions for static pressure balance and excellent lubrication. The flexible plastic piston seal high pressure oil that can self compensate for wear is adopted, so it has a higher efficiency of mechanical equipment and volume, and can operate smoothly at a very low rotational speed, The starting torque is relatively large.

4. Due to the characteristics of the structure, the oil return pressure required by the oil motor is low, and generally needs 0.3~0.8 mpa. The higher the rotation speed, the greater the pressure should be.

5. Because the oil distribution shaft is rigidly connected with the motor stator, the oil delivery pipe of this type of oil motor is allowed to be connected with stainless steel pipe.

6. This type of oil motor has two-stage and three-stage variable displacement, so it has a relatively large range of speed changes.

7. Simple structure, easy replacement, no special requirements for oil cleanliness, and the precision of oil filter can be selected according to the requirements of hydraulic oil pump.

8. Except for the shell type and the supported type, the output shaft of the hydraulic motor is generally allowed to bear the torque, not the radial and axial forces.

9. With a "T" type hydraulic motor, the center point has a through hole, and the output shaft can pass through the hydraulic motor.

10. The hydraulic motor with "S" type is equipped with self opening and closing mechanical equipment braking, which can complete reliable braking.

11. With "Se" and "SeZ" hydraulic motors, the starting and braking can be controlled manually or intelligently. The operating pressure is low, the brake torque is large, and the actual operation is convenient and reliable.

12. The speedometer can be assembled behind the "B" type hydraulic motor to show the rotation speed of the hydraulic motor.
