Description

Technical Field

[0001] The utility model relates to the field of a servo motor pump group of a hydraulic system, in particular to a servo motor pump group of a hydraulic system. Background Art

[0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power elements, actuators, control elements, auxiliary elements and hydraulic oil. The hydraulic system can be divided into two categories: hydraulic transmission system and hydraulic control system. The hydraulic transmission system is mainly used to transmit power and motion. The servo motor pump group is one of the power elements and is used to transfer fluid from a low-pressure area to a high-pressure area.

[0003] Existing hydraulic system servo motor pump groups, such as the iron case direct motor pump proposed in patent application number "CN201820131068.7", have a simplified structure and good pressure regulation performance through structures such as an iron case motor, a gerotor pump, and a pressure regulating valve group. A fan is provided on the rotating shaft of the iron case motor at one end away from the gerotor pump, which can achieve efficient heat dissipation of the iron case direct motor pump.

[0004] However, the fan is driven to rotate by the rotating shaft, and the fan increases the air flow rate of the surrounding environment. This method has a poor heat dissipation effect on the iron shell motor. When the motor runs at a large power or runs for a long time, more heat will be generated. The heat dissipation effect of this method is not sufficient. Therefore, a hydraulic system servo motor pump group is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A hydraulic system servo motor pump group, such as Figure 1-Figure 4 As shown, it includes a mounting seat 3, a base 2 is slidably connected inside the mounting seat 3, a motor pump body group 1 is fixedly connected to the upper end of the base 2, a plurality of groups of fixing columns 8 are fixedly connected to the rear side wall of the motor pump body group 1, a protective cover 7 is commonly fixedly connected to one side of the plurality of groups of fixing columns 8, a rotating shaft 9 is rotatably connected inside the motor pump body group 1, a fan blade 10 is fixedly connected to one end of the rotating shaft 9 located in the protective cover 7, a cold water pipe 15 for cooling is clamped on the side of the rear end of the motor pump body group 1, and the fan blade 10 is located on one side of the cold water pipe 15.

[0024] The support at the bottom of the motor pump body group 1 is formed by the mounting seat 3 and the base 2. The protective cover 7 is fixed to the tail of the motor pump body group 1 through multiple sets of fixing columns 8. The protective cover 7 prevents the rotating fan blades 10 from injuring people. A cold water pipe 15 is installed at the tail of the motor pump body group 1. The cold water pipe 15 is filled with a liquid with a lower temperature and then blocked. The air temperature around the cold water pipe 15 is lower. When the motor pump body group 1 is running, the rotating shaft 9 drives the fan blades 10 to rotate. The rotation of the fan blades 10 increases the air flow speed, so that the cold air around the cold water pipe 15 is blown to the side wall of the motor pump body group 1, thereby improving the heat dissipation effect.

[0025] There are multiple groups of spring plates 4 between the mounting seat 3 and the lower end of the base 2, and the multiple groups of spring plates 4 are all arranged in an arc shape. A stabilizing component is fixedly connected between the mounting seat 3 and the middle part of the lower end of the base 2.

[0026] like Figure 3 As shown, when the motor pump body assembly 1 generates vibration during operation, the base 2 shakes up and down in the mounting seat 3, which will squeeze or pull the spring plate 4. The spring plate 4 is passively deformed and has a certain resistance to prevent the motor pump body assembly 1 from vibrating. Cooperating with the stabilizing component, it plays a shock-absorbing role.

[0027] The inner wall of the protective cover 7 is fixedly connected with a plurality of mounting columns 12 arranged in a circular array, and the ends of the plurality of mounting columns 12 are commonly fixedly connected with an air guide plate 13, which is located between the protective cover 7 and the fan blades 10, and the opening of the air guide plate 13 is directly opposite to the cold water pipe 15.

[0028] like Figure 4 As shown, the air guide plate 13 is fixed inside the protective cover 7 through multiple groups of mounting columns 12. The airflow driven by the fan is guided by the air guide plate 13, so that the airflow is directed to the side of the cold water pipe 15, driving the cold air near the cold water pipe 15 to flow to the side of the motor pump body group 1, thereby improving the heat dissipation effect of the motor pump body group 1.

[0029] The rear side wall of the motor pump body assembly 1 is fixedly connected with a plurality of elastic clamping plates 14 , which are arranged in a circular array and have a clamping opening on one side thereof, and the cold water pipe 15 is clamped and matched with the elastic clamping plates 14 .

[0030] like Figure 1 As shown, the elastic clamping plate 14 is cylindrical, and the width of the clamping opening is smaller than the diameter of the cold water pipe 15 . The cold water pipe 15 is pressed into the elastic clamping plate 14 and clamped to the side wall of the motor pump assembly 1 .

[0031] The stabilizing assembly includes a damper 5, which is fixed between the lower end of the base 2 and the bottom wall of the mounting seat 3. A spring 6 is sleeved on the outside of the damper 5, one end of the spring 6 is fixed to the bottom of the base 2, and the other end is fixed to the bottom wall of the mounting seat 3.

[0032] like Figure 3 As shown, the damper 5 cooperates with the spring 6 to achieve a shock-absorbing effect, and cooperates with multiple sets of spring plates 4 to reduce shock between the base 2 and the mounting seat 3.

[0033] Both ends of the cold water pipe 15 are threadedly connected with a sealing head 16 , and a vent 11 is opened on one side of the protective cover 7 .

[0034] like Figure 2 As shown, the end cap 16 blocks both ends of the cold water pipe 15 to facilitate the addition of liquid with a relatively low temperature into the cold water pipe 15 , and the vent 11 facilitates the air circulation inside the protective cover 7 .

[0035] The working principle of a hydraulic system servo motor pump group provided by the utility model is as follows:

[0036] The protective cover 7 is used to prevent the rotating blades 10 from injuring people. A cold water pipe 15 is installed at the tail end of the motor pump body assembly 1. The cold water pipe 15 is filled with liquid with a lower temperature and then blocked. The air temperature around the cold water pipe 15 is lower. When the motor pump body assembly 1 is running, the rotating shaft 9 drives the blades 10 to rotate. The rotation of the blades 10 increases the air flow speed, so that the cold air around the cold water pipe 15 is blown to the side wall of the motor pump body assembly 1, thereby improving the heat dissipation effect.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
