Problems solved by technology

Neither the water source capacity for industrial and building fire extinguishing nor the water supply capacity of the firefighting vehicles owned by the fire brigade can meet the large-scale fire extinguishing water demand, and sufficient natural water sources are usually far away from the fire scene. How to continuously and large-flow deliver the fire extinguishing water to the fire The scene is a severe challenge for the fire brigade; at the same time, as the scale of Chinese cities continues to increase, the frequency of urban waterlogging and other disasters is also increasing year by year
Therefore, how to achieve large flow, long-term and long-distance water supply and drainage is a practical problem that must be solved for current fire protection and emergency rescue; at present, the suction height of domestic fire pump units is generally about 4m-6m, and the self-priming capacity Poor, the whole unit needs to be as close as possible to the water source; the traditional domestic water supply and drainage systems are generally driven by motors, which are large in size, inconvenient to move, and poor in mobility. They must be equipped with a generator of corresponding power or a place with power supply when working; During water supply and emergency drainage, due to the limitation of the geographical environment and the influence of the weather, the power supply has become a big problem; its work is to absorb water from the open water source through internal negative pressure. When the water source reaches a certain height from the ground, it cannot be placed in the water source. The water in the pump is sucked into the pump, causing the pump to suck up, the water at the water source cannot be sucked up, the seal of the impeller generates high temperature, the seal burns, and a large amount of water leaks
And all are limited by its low flow rate, low head, low suction; the preparation work before the operation is relatively cumbersome, resulting in a long time, greatly delaying the fighter; the existing technology can not meet people's needs; in order to make up for the existing technology Insufficient, the present invention aims to provide a kind of hydraulic system of floating type remote water intake device

Abstract

The invention discloses a floating type remote water taking device hydraulic system which comprises a hydraulic butterfly valve, an air filter, a variable displacement piston pump, a submerged pump driving motor, a speed control valve, a first solenoid directional valve, a bidirectional balance valve, a submerged pump recycling motor, an oil pipe recycling motor, a gear pump, an overflow valve, a second solenoid directional valve, a flow divider valve, a second overflow valve, a third solenoid directional valve, a hydraulic oil cooler and an oil return filter. According to the floating type remote water taking device hydraulic system, variable frequency constant pressure water supply is adopted by the whole system, pressure set on site is used as a parameter, the output frequency of a frequency converter is controlled through a microcomputer to regulate the rotating speeds of the motors automatically, the closed-loop regulation of water pressure of a pipe network is achieved, the system can be stabilized at a set pressure value constantly and automatically, water supply efficiency is guaranteed, and requirements of water yield are met. The overall floating type remote water taking device hydraulic system is strong in independence, large in flow, high in lift, simple and novel in structure, and convenient and fast to use.

Description

Technical field [0001] The invention relates to the technical field of remote water intake applications, in particular to a hydraulic system of a floating remote water intake device. Background technique [0002] With the rapid development of the current social economy, the fire situation has become more complicated. Whether it is the water supply capacity for industrial and building fire extinguishing, or the water supply capacity of fire fighting vehicles owned by the firefighting force, they cannot meet the demand for large-scale firefighting water, and sufficient natural water sources are usually far away from the fire site. How to continuously and large flow of firefighting water to the fire The scene is a severe challenge for the firefighting forces; at the same time, as the scale of Chinese cities continues to increase, the frequency of disasters such as urban waterlogging has also increased year by year. Therefore, how to achieve large flow, continuous long-term and long...
