Embodiment Construction

[0011] Such as figure 1 As shown, the downhole frequency conversion constant pressure water supply system provided by the present invention includes a reservoir, a main pump, and an orifice plate. The main pump is connected to a frequency conversion control device, and the frequency conversion control device automatically adjusts the water pump according to the change of the system pressure signal. The rotation speed of the motor meets the constant-pressure water supply requirements of the water supply system; the downhole variable frequency constant-pressure water supply system also includes a multi-pump controlled by one, which is used for the safe use of underground coal mining equipment. The technical scheme of the present invention directly uses underground water resources, and the frequency conversion constant pressure water supply technology freely sets the pressure according to the needs of the equipment, which improves the utilization rate of water resources; avoids th...

Abstract

The invention discloses an underground variable-frequency constant-pressure water supply system, which comprises a reservoir, a main pump and a pore plate. The main pump is connected with a variable-frequency control device, the variable-frequency control device automatically adjusts the rotation speed of a motor of a water pump in a frequency-variable manner according to change of pressure signals of the system, and the requirement on constant-pressure water supply of the water supply system is met. The underground variable-frequency constant-pressure water supply system directly utilizes underground water resources, the pressure is freely set according to needs of equipment by the aid of variable-frequency constant-pressure water supply technology, and utilization rate of the water resources is improved; secondary waste of energy is avoided, and furthermore, a large quantity of electric energy can be saved by the aid of the frequency-variable technology when flow is changed within a large range; steady precision of the pressure is improved, and the safety running performance and the reliability of production water equipment can be obviously improved; maintenance cost is greatly lowered due to automatic constant-pressure water supply, and unattended operation can be realized; and the underground variable-frequency constant-pressure water supply system guarantees that the pressure is within an allowable range.

Description

technical field [0001] The invention relates to an underground frequency conversion constant pressure water supply system. Background technique [0002] As the technical requirements for downhole production water are getting higher and higher, the use of static pressure water supply can no longer fully meet the safety production requirements of equipment. Therefore, an unattended automatic constant pressure water supply system with constant pressure, self-adaptive flow and various protection functions is needed. With the development of modern power electronics technology, computer control technology, information technology, and sensor technology, unattended automatic constant pressure water supply technology is in the critical stage of research and development. and life expectancy have been significantly improved. In addition, there will be a significant energy saving effect. Automatic constant pressure water supply is one of the most forward-looking technologies at prese...
