Technical Field
The utility model discloses a be applied to secondary pressurization water supply installation among the urban water supply network.
Background
With the development of domestic social economy, high-rise buildings are generally built for improving office and living conditions and urban planning, or residential districts are built in suburbs and higher-lying areas. Due to the particularity of geographical conditions and the height of buildings, the water pressure of tap water in the existing urban water supply network cannot meet the requirement, so that a water supply system after secondary pressurization is required to be matched to ensure the normal water supply of the regions and high-rise buildings.
The secondary pressurized water supply devices adopted at present mainly comprise the following two types, one type is non-negative pressure full-automatic water supply equipment which directly pumps water on a municipal pipe network. The main structure of the equipment is provided with a pressurized water pump unit, an electric control cabinet component and a related detection instrument. The equipment does not need to build a water storage pool additionally, directly utilizes the water pressure in the municipal pipe network, and realizes the pressurized water supply by the variable frequency speed regulation of the rotating speed of the water pump through the electric control cabinet component. However, the water supply device needs to be provided with a special pump room, so that the equipment not only occupies large space and has high operation noise, but also the maintenance of the whole device is complicated.
The other kind of secondary pressurized water supply device is built with a special water storage tank, and a submersible pump is arranged in the water storage tank to complete water suction and repressurization water supply. The main body of the device is also provided with an electric control cabinet and a related detection instrument. Although the device can also carry out variable frequency speed regulation on the submersible pump through the electric control cabinet according to the change of water consumption of a user to achieve the purpose of constant-pressure water supply, the water pressure in a city water supply pipe network is reduced to zero while part of water is stored in the water storage tank, and considerable electric energy is consumed to drive the water pump to supply water again and pressurize, so that the energy loss is large; meanwhile, part of water in the water storage tank can not be updated in time, so that the retention time is too long, bacteria and impurities are accumulated more, secondary pollution of the water in the water storage tank is easily caused, and damage to the human health of a user is easily caused by direct water supply.

Wherein,
the pipe pump comprises a pipe pump shell internally provided with a submersible pump, and the pipe pump shell forms a water absorption container for providing constant-pressure water supply for a water pipe network by the submersible pump.
The submersible pump in the shell of the pipe pump comprises a submersible pump body and a variable frequency motor which are connected into a whole, and the variable frequency motor is connected with an electric control cabinet arranged outside the pipe pump through a motor power line.
One end of the pipe pump housing is provided with a housing water inlet. The water inlet of the shell is connected with a check valve of the water inlet pipe communicated with the water supply pipe network in series so as to prevent the water in the pipe pump from flowing back to the water supply pipe network. The other end of the pipe pump shell corresponding to the water inlet of the shell is provided with a pump body water outlet, and a submersible pump water outlet check valve and a pump body water outlet are sequentially connected in series at the water outlet. The water outlet check valve can prevent the constant pressure water supplied to the water using pipe network from flowing back to the interior of the pipe pump. The water outlet of the pump body is connected with a main water outlet valve.
And a signal transmission line of the water outlet pressure sensor is connected with the electric control cabinet.
When the water inlet main valve is opened, water with certain pressure in the water supply pipe network enters the pipe-mounted pump shell through the check valve of the water inlet pipe. When the submersible pump operates, water enters the pump body from the water suction section of the pump body and then enters a user pipe network through the pump body water outlet check valve, the water outlet and the water outlet main valve for use by a user.
The connection structure of the electric control cabinet, the pipe pump and the water outlet pressure sensor can enable the pipe pump to realize variable-frequency speed-regulation constant-pressure water supply under the allocation of the electric control cabinet.
Specifically, the water flow rate is randomly changed, and the water outlet pressure of the water supply device is changed along with the change of the water outlet flow rate. When the water consumption is increased from small to large, the water outlet pressure is decreased from large to small, otherwise, when the water consumption is decreased, the water outlet pressure is increased. The changed instantaneous value of the water outlet pressure is timely transmitted to the electric control cabinet through the water outlet pressure sensor, and the electric control cabinet correspondingly outputs a power supply frequency instruction for changing the motor of the submersible pump.
When the power frequency is changed, the rotating speed of the submersible pump is changed. The final aim of each change is to ensure that the outlet pressure of the submersible pump is always kept at a constant value on the premise that the outlet quantity of the submersible pump meets the requirement of the change of the water consumption.

The low pressure controller is arranged on the shell of the pipe pump and can detect the water pressure at the water inlet of the pipe pump. The numerical value transmitted to the electric control cabinet by the low-voltage controller is the pressure value of the water in the pump shell of the pipe pump. In the operation process of the submersible pump, the urban water supply pipe network provides pipe network water pressure for the pipe-in-pump shell and transmits the pipe network water pressure to the electric control cabinet through the low-voltage controller. When the water consumption peak, the water pressure in the water supply pipe network can descend, and in case the water pressure value that low pressure controller measured falls to the minimum that allows normal water, the automatically controlled cabinet can control the motor shut down of above-mentioned pipe pump, then the immersible pump stops promptly to absorb water from the water supply pipe network to can guarantee that the condition that the negative pressure absorbed water can not appear, can not produce adverse effect to city water supply pipe network's normal work.
