On behalf of a subsidiary under the domestic Aerospace Science and Technology Group, to cooperate with its company in the research and development of intelligent robots, beforeating with our company, the customer has investigated many peers, including a hydraulic wrench manufacturer in Shanghai, and also experienced many frustrations, but in the end, they still chose to with us.

Design description of intelligent fully automatic multi-functional hydraulic pump (multi-purpose constant power hydraulic pump):
1.1 The low-pressure constant power pl pump is used to supply oil, and the pressure is increased to the required working pressure through the booster;
1.2 This system is a multi-purpose pump, which can low-pressure travel mechanism, hydraulic wrench and hydraulic tensioner respectively;

1.3 The oil inlet is equipped with a pipe filter to ensure the cleanliness of the system and extend the service life;
1.4 The working pressure is manually and automatically adjustable, equipped with a manual overflow valve and a pressure sensor, which can maintain pressure when it reaches the set pressure in the automatic operation state.
1.5 Considering the continuous working condition, a cooler is used for heat dissipation;

1.6 The pump station uses a lever-type solenoid valve to control the oil circuit;
1.7 The pump station is equipped with a gauge to observe the working condition of the pump station;
1.8 The suction filter is installed at the suction oil position;
1.9 It has an electric function.

The main technical parameters of the intelligent fully automatic multi-functional hydraulic pump (constant power hydraulic pump for multi-purpose) are as follows:

Control object: Nut stretcher; Hydraulic wrench, hydraulic motor
2.2 Pump type: Low pressure constant power plunger pump and booster;
2.3 Maximum working: 1400bar;

2.5 Output flow: 20L/ (14bar); 3.8L/min (280bar); 1L/min (700bar), 0.5L/min1400bar);

2.6 Temperature range: The pump station can operate normally with oil temperature between 5℃～70℃; the temperature rise is controlled within 0 degrees.
2.7 Medium: 46# anti-wear hydraulic oil;
2.8 Tank capacity: 50L;
2.9 Oilliness: NAS7 grade;
2.10 Pump station voltage: AC 380V 50Hz three-phase alternating current power supply;
2.1 Motor technical requirements: AC 380V 50Hz 1.5KW, four-pole, three-phase motor;
2.12 The of the power unit during normal operation shall not exceed 75 decibels;
