Daikin plunger pump
Daikin plunger pump is an important device of hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil absorption and pressure. Plunger pumps have the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. They are widely used in occasions where high pressure, large flow and flow need to be adjusted, such as hydraulic presses, construction machinery and ships. The performance overview of daikin plunger pump is as follows: V-type plunger pump, with a unique design of the swash plate to change the angle function. It is widely used in various places. Special design to maintain low noise performance in the full pressure zone. The integration of multiple control methods can form a system, which has the advantages of energy saving, miniaturization, and low-cost functions. The power loss is small, the oil temperature rise is reduced, and a smaller oil tank is optional. It is widely used in machine tools, machine tools, forging, plastic forming machines, etc. Low noise, all pressure ranges in each series have realized low noise operation; high efficiency, due to small power loss; good reliability, high sensitivity, high stability, and long life, which increase the reliability of the host.
Daikin vane pump
Daikin DAIKIN compact single-stage vane pump has low noise-due to the size of the suction port is large enough, the resistance through the suction port is small, thus achieving low noise operation. High efficiency-The elastic cushion system keeps the lateral clearance constant, so the low-pressure pump has no blockage and wear, and can maintain stability and high efficiency. Low pulsation-because the cam cannot reduce the change of displacement, the running sound is small, the pulsation is small, so the characteristics of good stability, etc. have the advantages of uniform flow, stable operation, small noise, small size, light weight and so on. It is widely used in machine tools, engineering machinery, ships, die-casting and metallurgical equipment. The working pressure of medium and low pressure vane pumps is generally 8MPa, and the working pressure of medium and high pressure vane pumps can reach 25MPa to 32MPa. The disadvantage of vane pumps is that they are more sensitive to oil pollution than gear pumps, and require higher oil cleanliness; and due to the influence of vane ejection force, oil suction speed and wear and other factors, the speed of the pump should not be too high, nor should it be too high. Small, generally can be used in the range of 600~2500rpm; the structure of the pump is also more complicated than the gear pump.
Vane pumps are mainly divided into two forms: single-acting (perfect suction and discharge of oil once per rotor revolution) and double-acting (suction and discharge oil twice per rotor per revolution). Compared with the single-acting vane pump, the double-acting vane pump has better flow uniformity, and the radial hydraulic pressure on the rotor body is basically balanced.
High-density media discharge: Due to the use of a supporting swash plate, it is small, lightweight, and high-pressured, thereby increasing the output power per unit weight.
Low working noise: While improving the rigidity of the swash plate structure, the frame designed with the latest measurement and analysis technology is used to greatly reduce the running noise.
High efficiency: The use of ball valve plate and suitable oil pressure balance expands the operating conditions and produces high efficiency.
Long-term operation: Due to the use of excellent wear-resistant ball valve plates, the anti-pollution characteristics are strengthened.

(*Compared with a conventional Daikin vasiable piston pump)
Air-conditioning motor technology and tandem pump selecting control technology are fused to attain high energy saving effects.
Not only at retained pressure but also in the field of general industrial machinery where actuators are frequently operated, such high-efficiency motors will greatly reduce power consumption and other energy savings.
2. Low heat generation
In view of the energy-saving goal, generation of heat is dramatically suppressed and it can reduce the heat load to the air-conditioning unit.
This reduces the heat load on the air-conditioning unit. Effectiveness by low heat generation.
Preventing rise of oil temperature and deterioration of operating oil
Space savings and the reduction oil capacity given that tank size is reduced

3. Low noise
Low noise 60dB (A) (20.6MPa at retained pressure) is achieved. In all of the operation areas, the noise is 73dB(A) or less.
The motor is controlled at a lowest optimum speed under retained pressure condition, which achieves the extremely low noise level.
The phase-differential tandem pump attains low pulsation and low noise (Double-pump specification)
4. Excluded from high-efficiency motor regulations
High-efficiency motor regulations came into effect in Japan in April 2015. These regulations apply to the hydraulic units equipped with general motors but the SUPER UNITs that incorporate a high-efficiency IPM motor are excluded from them.
