Embodiment Construction

[0011] Such as figure 1 , 2 As shown in , 3, in the start-up water injection stage, all the valves (1) on the water supply and return in the low area, the valve on the water collector (2), the valve (3) on the unit, etc. are all opened, and water is injected into the system in the high area, and the system water passes through the cyclone After flowing through the decontamination device (4), it enters the water supply pipe in the high area, and the pressurized circulating water pump (6) is started and stopped by the undervoltage protection pressure sensor (5), and the solenoid valve (15) is always closed by manual control until the user in the high area ( 12) There is water, until the exhaust valve (13) does not exhaust. During normal operation, when the pressure sensor (11) for constant pressure of the unit indicates that the exhaust valve (13) of the system of the user in the high area (12) does not exhaust, and there is a certain pressure, the frequency conversion control ...

Abstract

The invention relates to a high-low-area direct-coupled unit of an energy-saving pressure-reducing substitutable-type turbine pump, which aims at solving the heating and energy-saving problems of high-rise buildings, and adopts a technical scheme that: on a closed-type water supply-return heating pipe network, a pressurizing water circulating pump is used for pumping low-area water with pressure of a certain degree from a low-area water supply pipe to be supplied to a high-rise building, the water pump is controlled by a variable-frequency controller, a program logic controller (PLC) and a pressure sensor, a high-area pipe network is protected against vaporization and emptying, hot returned water which is used by the high-rise building is decompressed by a hydroturbine of the energy-saving pressure-reducing substitutable-type turbine pump, so the returned water of the low area is free from over-pressure. Energy which is produced by reducing the pressure of the returned water from high area to the low area is coaxially transferred by the energy-saving pressure-reducing substitutable-type turbine pump to a water pump head for pressurizing on the other end at identical speed or at different speeds, so pump lift of the supplied water is provided, and the pressurizing water circulating pump runs at a variable and low frequency to further save the electric energy.

Description

Technical field: [0001] The invention relates to heating equipment, in particular to an energy-saving decompression replacement type water turbine pump high and low area direct-connected unit. Background technique: [0002] At the turn of the century, with the development of the economy, high-rise buildings have sprung up on the land of China. What followed was a change in the heating method of high-rise buildings. In the HVAC industry, the system separated by a closed heat exchanger does not consider the height difference of the building because the lift of the circulating pump only needs to consider the height difference of the pipeline. Along the way and local joints, it is the most energy-efficient to solve the heating of high-rise buildings. However, due to various reasons, especially the low water supply temperature, it is impossible or uneconomical to exchange heat. Therefore, on the basis of using the water pressure in the low heating area, the heating method of sup...
