Description
Technical field
The present invention relates to a kind of water pump with photoelectricity fluid sensor.
Background technology
Water flow switch is one kind of fluid switch, and it is that one kind is being incited somebody to action after certain flow is reached by taking water flow sensing unit as an example
Current are converted to the senser element of switching regulator electric signal, can be used for electric heater, solar water heater, air-conditioner and other water
The water circulation of system is controlled, turnover water management, water computer heating control, pump switch are controlled, magnetic valve break-make is controlled or water outlet is powered off,
The processes such as water outlet power control.Amount (flow, that is, liquid flow dynamic pressure for whether being flowed to liquid in signal piping and being flowed
Power) whether requirement is reached, while by switch electric contact output (offer) state for the break-make of signal.Device systems are by detection
There are no signal or control electric current to judge pipe-line system by (the switching state of water flow switch electric contact) from this switch
Working condition, provides corresponding control or the method for operation or measure；It is capable of achieving following monitoring function：Media flow, reduces/improves
Flow velocity；Medium in the presence/absence of；Media flow/static；Monitoring pipeline inner fluid speed size, cutout monitoring prevent pump
Idle running.
Water flow switch its primary structure is that the magnet that can be moved with water (flow) direction is provided with water flow switch cavity, in water
Stream switch cavity sets the tongue tube that can be triggered by magnet in vitro.Water flow switch entrance is flowed through in current, magnet movement, magnet is promoted
Triggering tongue tube action, tongue tube sends signal, and whether controlled motor starts.
There is following defect in existing water flow switch：1st, the action of magnet needs certain stroke and time, therefore not enough
It is sensitive；2nd, can not be worked in the environment of having magnetic field, because the magnetic field in the external world can cause the misoperation of water flow switch；3rd, need compared with
Big initial kinetic energy could promote magnet to move, and such as the water flow switch be used in water pump, in the course of work of water pump weep
In, water flow switch akinesia；4th, tongue tube is fragile, and water flow switch is integrally located in the pump housing in addition, and dimension is difficult after its damage
Repair replacing；5th, cannot be applied in the water environment for having impurity, easily be blocked by impurity in the passage of magnet sliding, adsorbed and stuck；6、
Electric property insulation is poor, and security cannot be ensured.In sum, traditional water flow switch can be further improved.
Check-valves refers to be flowed in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its Main Function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.
The check-valves used in existing water pump, is typically mounted in water inlet, and its structure includes being provided with the valve seat of valve port, wears
The valve rod that be located on valve seat and can slide up and down, one end of valve rod is connected with to block the valve block of valve port, and valve block is located at valve seat
Lower section, be also arranged with valve rod make valve rod keep on move so that valve block blocks the spring of valve port trend.When there is current normal
By water inlet, the impulse force of current understands ejection valve block, and valve block and valve rod can overcome the elastic force of spring, is slided towards the direction for opening valve port
Move, now valve port is opened, current are entered in the pump housing by valve port, finally flowed out from the outlet of the pump housing, when motor no longer works, water
Stream is no longer flowed into from water inlet, and valve rod can under the action of the spring, and band moving valve plate blocks the movement of valve port direction, prevents current from falling
Stream.
This check-valves only one of which one-way cock structure thereon, water pump operationally, because of many environment under, water pump draws up
The water for coming, it carries many impurity, if there is impurity to be deposited in the keying position of valve, may result in whole one-way cock and closes not
Sternly, at this moment whole one-way cock does not just have closing function, and the water in the pump housing can flow backwards from check-valve port and damage impeller and electricity
Machine.And the diversion in the pump housing can be lost in, there is no diversion in the self priming pump pump housing, self priming pump can lose self-suction function.Water pump can not
Normally use.Other check-valves, when valve port is opened, is fully open state, is not blocked at valve port, water pump operationally, one
A little harder impurity, such as finger stone can enter with current via check-valves can collide the impeller of motor in the pump housing, serious meeting makes
Impeller failure.
The content of the invention
The technical problems to be solved by the invention be directed to above-mentioned state of the art and provide a kind of sensitivity it is higher, peace
Good perfection, simple structure, cheap and non-damageable photoelectricity water flow sensing unit.
