状態で運転して故障発生のおそれがあることになる。C. Conventional technology] In the first place, unlike those for water wells, submersible motor pumps for deep wells for hot springs are usually subject to changes in temperature, spring quality components, gushing volume, water level (head) changes, installation depth, water pressure changes, demand volume changes, etc. The limits may be exceeded, and complex conditions are involved, including gas contamination, scale adhesion, corrosion, etc. Therefore, not only motors and pump products, but also their operation must be carefully controlled to suit the conditions of each well.・Although it requires management, conventionally, this type of deep well motor pump for hot springs operates at its rated value regardless of fluctuations in the demand volume, water level of the well, and various conditions such as the amount of water flowing out. At present, when water is low, the water supply pulp is adjusted by tightening the hot water supply pulp, and the hot spring deep well submersible motor pump is repeatedly started and stopped to match various conditions such as demand. It is. However, when the deep well submersible motor pump for hot springs is operated at its rated condition,
If the hot water supply valve is adjusted by tightening it, there is a risk of operation in a dangerous unstable region and failure.

かった。Due to the complexity of the conditions, once hot spring pumps are operated,
Continuous operation without frequent stops is better in terms of lifespan, so if you continue to operate at full capacity without making adjustments, hot springs will be pumped out and released even when it is unnecessary, which will not only be a waste of hot spring resources. However, the electric power supplied to the deep well submersible motor pump for hot springs also has a problem of being uneconomical because the amount of electricity consumed is large compared to the amount required for hot springs. In addition, the method of adjusting the operation and stop of the deep well submersible motor pump for hot springs to suit various conditions is undesirable and increases the failure rate of the deep well submersible motor pump for hot springs. Adjustment of frequency and time of day was also not as expected.

Deep well water for hot springs uses an inverter that allows for variable characteristics, which enables economical operation with a low failure rate, prevents depletion of underground hot spring resources, and saves labor through unmanned management. The purpose of the present invention is to provide a method for controlling a medium motor pump.

定格運転が行われる。An embodiment of a method for controlling a hot spring deep well submersible motor pump using an inverter according to the present invention will be described below. In FIG. 1, 1 is a hot spring deep well submersible motor pump installed in a well. Hot spring deep well submersible motor pump 1
consists of a pump section 3 having a suction port 2 and a motor section 4 for driving the pump 3. The deep well submersible motor pump 1 for hot springs lifts hot water from inside the well through a pumping pipe 5, and supplies the hot water to a predetermined location via a valve 6. A hot spring deep well submersible motor pump 1 is conventionally driven by a control surface 7. That is, after passing through the control surface 7 from the secondary power source 8, rated power is supplied to the motor section via the underwater cable 9, thereby performing rated operation.

ることができる。In this state, it is operated with a commercial frequency power supply, and as shown in FIG. 2, it exhibits the maximum efficiency η for a certain amount of hot water Q (n?/m1n). Moreover, if the frequency of the electric power supplied to the deep well submersible motor pump 1 for hot springs is varied, the maximum efficiency η will also shift from side to side. An inverter 10 that can freely vary the frequency of the power supplied to the hot spring deep well submersible motor pump 1 is connected in parallel to the control surface 7, as shown in FIG. Then, the inverter 10 and the control surface 7 are selected and operated by switching. That is, the driving of the hot spring deep well submersible motor pump 1 is normally controlled by the inverter 10, and the driving of the hot spring deep well submersible motor pump 1 is controlled by the control surface 7 as necessary. Of course, the well electrode 23 that responds to the lowest water level is also connected to the inverter 10. The inverter 10 varies the frequency of the power supplied to the hot spring deep well submersible motor pump 1 in response to changes in various conditions such as the amount of hot water supplied and the water level in the well. For example, as shown in FIG. 3, when the required amount of hot water supply is extremely small, the standard frequency 1 is reduced from, for example, 50 Hz to about 35 Hz. The frequency to be reduced is changed to a frequency that provides the maximum efficiency for the required amount of hot water supply. Conversely, as shown in Fig. 4, if the required amount of hot water supply increases, the frequency is changed to obtain the maximum efficiency for this increased amount of hot water supply. As shown in Figure 4, the water level in the well 11 often decreases as hot water is supplied.In this case, the actual head at which the water level falls, the so-called actual head (m), changes, so the amount of hot water supplied (nr
The frequency supplied from the inverter 10 to the deep well submersible motor pump 1 for hot springs is varied and adjusted in response to not only changes in the actual head (m) but also changes in the actual head (m). Actual pumping height (m) due to changes in demand or seasonal changes in well water level
If the hot spring deep well submersible motor pump 1 is driven at the standard frequency even though the current has increased from H3 to H2, as shown in FIG. (m) moves from point A to point B on the standard characteristic curve 12 of the pump. Therefore, fried water i
Not only does Q increase from the required amount Q to Q2, but as shown in the power characteristic curve 13, the power P also increases from Pl to Pz. On the other hand, the inverter 10 causes a change in the actual head Hl−H
If the frequency of the power supplied to the deep well submersible motor pump 1 for hot springs is reduced in accordance with 0 of the frequency reduced characteristic curve 14 from the point
Move to a point. Therefore, the hot spring deep well submersible motor pump 1 pumps only the amount of hot water that is needed. Moreover, the power characteristic curve changes from 13 to 15, and along with this, the power P changes to P
Since it moves from + to P3 of the variable power curve 15, P
The power consumption is reduced by the difference between P2 and P3, resulting in savings. The power consumption when changing the power frequency supplied from the inverter 10 to the hot spring deep well submersible motor pump 1 is theoretically calculated based on the standard frequency being 100% and the pump shaft power at this time being 100%. As shown in the table below, the power consumption can be significantly reduced and power consumption can be reduced.

通りである。In addition, when controlling the drive of the hot spring deep well submersible motor pump 1 by the inverter 10, for example, in the case of a well where the water level is shallow at the start of operation (or the water level gradually decreases before normal operation starts), the inverter 10 controls the drive of the hot spring deep well submersible motor pump 1. The frequency of the power supply supplied to the well submersible motor pump 1 is increased step by step as shown in FIG. As the width of the frequency to be changed becomes narrower, the amount of hot water pumped approaches Q4 and changes linearly.Therefore, the pump performance is controlled so as not to deviate from the range of the appropriate amount of hot water pumped.In other words, the conventional method In this case, if the frequency of the power supply supplied to the hot spring deep well submersible motor pump 1 remains the same, as shown in FIG. L, and then from M to I. As a result, in the conventional method, there are times when the operation is not only within the range F of the appropriate amount of hot water pumped, but also within the unstable region 18. In addition, the range 17 of the appropriate amount of hot water pumped is There is also an unstable region 19 on the other side.It is well known that if the operation is performed in the unstable region 18.19, cavitation will occur and cause a failure of the hot spring deep well submersible motor pump l. .

As shown in the figure, the required amount over time for one day is predicted in advance, and this predicted amount is applied to the inverter 10, especially the inverter 1.
The timer is set to 0, and the hot spring deep well submersible motor pump 1 is controlled by this set value. For example, from 9:00 pm on the previous day to 6:00 am the next day, the amount of hot water used is low, so set the minimum amount of hot water. Set to @, 8:00 to 16:00
Since the amount used is small by the time, the amount of boiling water is the same as in the previous ■■

It is also possible to do so. In this case, the hot spring deep well submersible motor pumps 1a to IC pump the hot water into the hot water storage tank 20, and from within the hot spring tank 20, another pump pumps the hot water to each point of use.

are attached, and the inverters 10d to lof are connected to be controlled by the central control device 21. Then, the drive of each hot spring deep well submersible motor pump 1d to 1f is controlled according to the state or condition of each well lid to llf, such as water temperature, water level, and gushing amount. For example, each deep well submersible motor pump 1d~ for hot springs is designed to reduce the amount of hot water per unit time from the well 116 with a small amount of gushing water, and to increase the amount of hot water per unit time from the wells lid and If with a large amount of gushing water. 1f is controlled by each inverter 10d to 10f. The hot water pumped up by the deep well submersible motor pumps 1d to 1f for hot springs is once sent into a hot water storage device 22, and then is further supplied from the hot water storage tank 22 to the point of use by another pump. Of course, this hot water supply pump can also be controlled simultaneously by an inverter. Each of the inverters 10d to 10f is managed by a central control device 21 and its operation is controlled.

である。Furthermore, in outdoor well sites such as those in cold regions, continuous operation may be required to prevent freezing, and it is generally preferable that the hot spring deep well submersible motor pump 1 be operated continuously without stopping. Of course. In this case as well, the drive of the hot spring deep well submersible motor pump 1 can be controlled to the minimum amount of hot water pumped by the inverter 10, which is extremely convenient.

In addition, conventionally, the maximum rotation speed when directly connected to the motor was 3.60 Orpm, which was the final rotation speed due to two poles at 60 Hz, which was the limit, but depending on the inverter 10 described above, the maximum rotation speed was 120 Hz.
, or 240 Hz, and along with this, the function can be increased to the limit rotation speed as a pump function.

It is economical as it can be varied within an appropriate range and saves power consumption.
It also prevents breakdowns caused by repeated stops and starts, and since it does not pump out unnecessary amounts, it not only prevents the depletion of underground hot spring sources, but also helps in automating operation control in the future. It is extremely convenient and can also be expected to save labor through unmanned management.
