1. Structural design
Plunger structure:
The plunger structure of the DMS series plunger motor is exquisitely designed, and each plunger is precision processed and heat treated to ensure its high strength and wear resistance. The head of the plunger is designed with a special sealing structure, which can effectively prevent hydraulic oil leakage while ensuring stable sealing performance in high-pressure environments. The plunger rod is made of high-strength alloy material, which can withstand high-frequency reciprocating motion and is not prone to fatigue fracture. The design of the plunger cup also fully considers the dynamic characteristics of the fluid to optimize the flow path of the hydraulic oil and reduce energy loss.
Disc flow distribution:
Disc flow distribution is one of the core technologies of DMS series plunger motors. It uses a set of precision-machined valve plates to achieve precise distribution and recovery of hydraulic oil through the relative movement of rotating and fixed plates. This flow distribution method not only improves the utilization rate of hydraulic oil, but also significantly reduces the pressure loss and temperature rise of the fluid during the flow process. At the same time, the disc type flow distribution also has the advantages of compact structure and easy maintenance, making the overall performance of the motor more superior.
Radial arrangement:
The plungers of the DMS series plunger motor are arranged in a radial manner. This design makes the force between the plungers more uniform and reduces the vibration and noise caused by uneven force. The radial arrangement also helps to improve the heat dissipation performance of the motor, because the plunger generates a lot of heat during reciprocating motion, and the radial arrangement can make it easier to transfer the heat to the motor casing and cool it through natural cooling or forced cooling way to spread out. This design not only extends the service life of the motor, but also improves its working stability and reliability.
Pressure Level:
The DMS series plunger motor has a high pressure level, which is the key to its stable operation under various complex working conditions. A high pressure rating means the motor can withstand higher operating pressures without leakage or damage. This is due to the high-strength materials and precision sealing structure used inside the motor. At the same time, the high pressure level also enables the motor to output greater torque and power to meet the needs of various heavy-load and high-speed working conditions. Therefore, DMS series plunger motors have been widely used in mining, cranes, geological drilling and other industries.
Diverse accessories:
The design of DMS series plunger motors fully considers the different needs of users and provides a variety of accessory options. Users can choose different types of valves and brakes to match the motor according to actual needs. These accessories not only improve the flexibility and adaptability of the motor, but also enable the motor to perform better under specific working conditions. For example, users can choose a valve with an overload protection function to prevent damage to the motor in the event of overload; or choose a brake with an emergency braking function to ensure that the motor can be stopped quickly in an emergency. This diverse accessory design makes the DMS series plunger motor a powerful and widely used hydraulic power equipment.
The working principle of the hydraulic piston motor is mainly based on Pascal's principle and the basic principle of hydraulic transmission. When high-pressure hydraulic oil enters the motor through the oil inlet, it will act on the end face of the plunger to generate a huge thrust. This thrust is transmitted to the output shaft through the plunger rod, causing the output shaft to start rotating. During the rotation process, the plunger will continuously move from the high-pressure area to the low-pressure area, and in the process, the hydraulic energy will be converted into mechanical energy and output to the external load. At the same time, as the plunger reciprocates, the compressed hydraulic oil will be discharged from the motor through the oil drain port and returned to the hydraulic system for recycling.
Specifically, when hydraulic oil enters the motor, it will first impact the head of the plunger and push it backward (that is, away from the oil inlet). At this time, the rod part of the plunger will move relative to the part connected to the output shaft and drive the output shaft to rotate. As the plunger continues to move backward and gradually approaches the low-pressure area, the thrust force it receives will gradually decrease until it reaches zero. Then due to the fluidity and inertia of the hydraulic oil, the plunger will start to move forward (that is, toward the direction of the oil inlet) and be impacted by the hydraulic oil again. During this process, the plunger will continue to reciprocate and drive the output shaft to continuously rotate to achieve continuous power output.
It should be noted that the sealing structure inside the motor plays a vital role during the entire working process. It must be able to effectively prevent the leakage of hydraulic oil and the intrusion of external impurities to ensure the normal operation and stable performance of the motor. At the same time, the motor's lubrication system also needs to be maintained in good working condition to provide sufficient lubrication and cooling to reduce wear and extend service life.
