Abstract
The utility model provides a take water pump of pressure compensation function, belongs to the manufacturing of machine -building field, especially water pump for the transport and the pressure boost of running water still can be used to the transport and the pressure boost of other liquid. The utility model discloses a characterized in that: in the shell, set up a pressure airbag, the gasbag suit is in the inside of shell, the outside of kuppe, elastic material makes for the gasbag, has the elasticity. Pressure compensation through the gasbag acts on, can reduce the number of starts of water pump, can enough practice thrift power consumption, is favorable to the stability of circuit again.
Description
Technical field: a kind of water pump with pressure compensation, belongs to mechanical manufacturing field, particularly water pump manufacture, for conveying and the supercharging of tap water, also can be used for conveying and the supercharging of other liquid.
Background technique: in use, the heat self produced finally leans on the shell of motor and ambient air to carry out heat exchange and spread out of by heat the motor of water pump, reaches the effect of cooling.Particularly booster water pump, owing to being arranged on water supply pipe, general mounting point is all in indoor or inspection shaft, and pump housing ambient air mobility is poor, and the cooling effect of motor is poor, and temperature rise is higher; Application number be 201520102217.3 patent application " a kind of water pump " provide a kind of booster water pump with water cooling function, solve motor cooling problem.Due to the control signal that suction booster is opened as water pump by the pressure of waterexit end, stops, and the volume of water is incompressible, as long as user side uses water on a small quantity, will allow starting mode of pump, start frequently, close, not only waste electric energy, and affect the working life of motor.Current, there is people to compensate the pressure of waterexit end by arranging a pressure gas holder on water pump limit, solve and open frequently, stop problem, but gas holder volume is large, heavy, for low power water pump, is not very applicable.
Summary of the invention: the control signal being opened as water pump by the pressure of waterexit end due to suction booster, stop, and the volume of water is incompressible, as long as user side uses water on a small quantity, will allow starting mode of pump, open frequently, stop, not only waste electric energy, and affect the working life of motor.Task of the present utility model is for existing water pump, particularly suction booster, opens frequently, stops problem, designs a kind of water pump with pressure compensation.
The utility model adopts the scheme arranging air bag in pump: a kind of water pump with pressure compensation, is made up of shell, air guide sleeve, motor, pump, water inlet-outlet segment and base.It is characterized in that: in shell 1, be provided with a pressure air bag 2, air bag 2 is sleeved on the inside of shell 1, the outside of air guide sleeve 3, and if do not established air guide sleeve, be then directly sleeved on the outside of motor and water pump, air bag 2 is made with elastic material, has stretchability.
In the size of shell 1 and air bag 2, air bag, the large I of Preliminary pressure-filled designs according to the service condition of product.
When starting mode of pump, tap water enters water inlet-outlet segment 6 from water intake 8, by center cavity 10, enters pump 5, and pump 5 is discharged to water in cooling channel 11, and the pod apertures 13 through air guide sleeve 3 upper end enters into return flow line 12, then flows to water outlet 9.When system pressure is greater than Preliminary pressure-filled in air bag 2, be exactly specifically that water pressure in return flow line 12 is when being greater than the air pressure in air bag 2, intrasystem water starts extruding gasbag 2, make air bag volume-diminished, air bag inner air pressure increases, until air bag inner air pressure is consistent with the water pressure in return flow line, when namely reaching the preset pressure of suction booster, water pump quits work.
When user's water, system internal water pressure reduces, now in air bag 2, air Peng is swollen, and air bag volume increases, and the water in return flow line 12 is discharged, make to keep certain pressure in system, water pump can not start immediately, and when intrasystem pressure is less than Preliminary pressure-filled, water pump restarts work, again air bag is extruded, gas in compressing gasbag.By the pressure compensation effect of air bag 2, the number of starts of water pump can be reduced, can either saving power consumption, be conducive to again the stable of circuit, because electric current during electric motor starting is than much larger during normal work.
Accompanying drawing illustrates: Fig. 1 is a kind of structural representation of the water pump with pressure compensation, in figure: 1---shell, 2---air bag, 3---air guide sleeve, 4---motor, 5---pump, 6---water inlet-outlet segment, 7---base, 8---water intake, 9---water outlet, 10---center cavity, 11---cooling channel, 12---return flow line, 13---pod apertures, 14---cover plate, 15---fixing bolt.
Embodiment:: a kind of water pump with pressure compensation, is made up of shell, air guide sleeve, motor, pump, water inlet-outlet segment and base.It is characterized in that: in shell 1, be provided with a pressure air bag 2, air bag 2 is sleeved on the inside of shell 1, the outside of air guide sleeve 3, and if do not established air guide sleeve, be then directly sleeved on the outside of motor and pump, air bag elastic material is made, and has stretchability.In the size of shell and air bag, air bag, the large I of Preliminary pressure-filled designs according to the service condition of product.
