Abstract

PURPOSE:To make use of a wide range of wind and water power from low speed to high speed by providing a control valve to control the delivery amount of a pump for reducing the driving power of the pump as maintaining the delivery pressure of the pump at a constant level at the time of low velocities of the wind and water. CONSTITUTION:When wind velocity is almost near to zero, the energy to drive a wind mill 1 and an oil pump 3 cannot be obtained from the wind power, and the oil pump 3 cannot be driven. However, since the oil pump 3 is of variable capacity and the delivery amount is controlled almost at zero by a control valve 10 when the delivery pressure of the oil pump 3 is under a set value, the driving power of the pump 3 is very small. Therefore, when the wind velocity comes into a lowwind-velocity area a little higher than zero, the wind mill 1 and the oil pump 3 are started to drive, and pressure oil is sent and discharged by pressure to a discharge pipe passage 5.

駆動させるようにした風水方式ポンプ駆動装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feng shui pump driving device that uses feng shui power as a power source to drive a pump such as an oil pump.

ポンプ駆動装置が提案□されている。Recently, from the viewpoint of saving resources, a windmill or a waterwheel that is rotationally driven by wind and water power, and a pump that is driven by the rotation of the windmill or waterwheel are installed, and the fluid energy of this pump is driven by the wind and water power. A feng shui pump drive device has been proposed that utilizes energy as it is or by converting it into thermal energy or the like.

いう問題があった。However, in the above proposal, the pump is of a constant displacement type, and the discharge amount per revolution is constant regardless of changes in the discharge pressure, that is, the flow velocity such as wind speed, so it is difficult to drive the pump even at low flow velocity. requires a relatively large amount of power from the shaft 4, making it impossible to drive the pump, and even if it were possible to drive the pump, the pump's discharge pressure is too small - typically in the low flow rate range, which is often the case. There was a problem that it became impossible to use Feng Shui power.

装置を提供せんとするものである。The present invention has been made in view of this point, and includes a feng shui type pump drive device as described above, in which the pump is of a variable displacement type, and the discharge amount control section of the pump is controlled in accordance with the discharge pressure signal of the pump. By providing a discharge amount control valve to maintain the pump discharge pressure at a set value at low flow speeds, it is possible to reduce the discharge amount per revolution of the pump at low flow speeds. It is an object of the present invention to provide a feng shui type pump drive device that can utilize a wide range of feng shui forces from low speeds to high speeds.

Ｉ瞬はフィルタである。The oil pump (3) of the pump unit (2) is of a variable displacement type, and the pump unit (2) has a discharge amount of the oil pump (3) depending on the discharge pressure of the oil pump (3). A discharge rate control section (field) is provided which controls the control section (3b). That is, the discharge rate control valve (10) is connected directly downstream of the oil pump (3) via the pilot pipe (U). through the discharge pipe (!53, and another pilot pipe 02) to the tank (+Tsuji, and then another pi, lot pipe (14)
) are respectively connected to the discharge rate control part (3'b) of the oil pump (3), and the discharge rate control valve (at one end of the field) (Ilot pipe (ll) and The discharge pressure signal of the oil pump (3) is inputted through the 0 clause.Then, the discharge pressure of the oil pump (3) inputted to one end of the discharge amount control valve (10); Spring 00a) provided in the spring chamber at the other end of the discharge amount control valve (lO)
When the biasing force value of the discharge amount control valve (lO
) is located on the right side in the figure, and the discharge rate control unit (3b) of the oil pump (3) is opened to the tank via pilot pipes θ4) and (12), so that the discharge rate control unit ( The variable discharge amount control element (3a) is displaced toward neutrality by the biasing force of the spring (3C) of the oil pump (3b).
), and when the discharge pressure of the oil pump (3) inputted to one end of the discharge rate control valve (10) exceeds a set value, the discharge rate is controlled by that pressure. The valve (lO) is switched to the left position in the figure, and the hydraulic pressure (discharge pressure of the oil pump (3)) in the discharge pipe (5) is controlled by the pilot pipes (11) and (+4) to control the oil pump. (3
), the discharge rate variable control element is tilted against the biasing force of the spring (3C) of the discharge rate control unit (3b), thereby controlling the oil pump (3). Proceed in the direction of increasing the discharge amount per revolution of the oil pump (3), and increase the discharge amount per revolution of the oil pump (3) until the pressure of the pilot pipe (1) is balanced with the spring (10 m).
As a result, the discharge pressure of the oil pump (3) at low wind speeds is controlled to be maintained at the set value. still,(

When the discharge pressure of the oil pump (3) is lower than the set value, the discharge amount per revolution of the oil pump (3) is controlled to approximately zero (extremely small) by the discharge amount control valve (lO). The shaft power of the nuclear oil pump (3) is extremely small. Therefore, in the low wind speed region (where the wind speed is slightly higher than zero)
For example, when the temperature reaches 3.8 to m/B), the wind turbine m and the oil pump (3) start to be driven by the wind force, and the oil pump (3) receives pressure from the oil pump (3) by driving the nuclear oil pump (3). Oil is discharged under pressure into the discharge pipe (5). As a result, the pressure oil whose oil temperature has increased due to the throttling effect of the relief valve (7) is used as a heat exchange medium in the cold water pipe (
9), heat exchange is performed with the cold water as the usage-side cooling medium flowing through the cooling water, and the cold water can be heated. Moreover, in this case, the oil pump ( 3)
The discharge pressure of is kept constant.

うにした風力式ポンプ−動装置にも適用できる。On the other hand, the wind speed will further increase, ranging from medium winds to high wind speeds (
For example, if the oil pump (
3), the discharge amount per rotation approaches the maximum discharge amount (in other words, the oil pump (3) is not tilted to the maximum tilt angle with variable discharge amount control and large wind speed), and the oil pump (3) is tilted to the maximum tilt angle. Since the discharge pressure increases as the wind speed increases, it is recommended to use high-pressure oil for heat exchange. In the above embodiment, the oil pump (3) is driven using wind power as the power source. Although we have explained the case where it is applied to a wind-powered pump drive device,
The present invention can also be applied to a wind-powered pump-driven device that uses wind power as a power source to drive a water pump.
