Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the utility model provides a kind of low energy consumption automatic steady die mould diaphragm pump, including motor 1, electricity
Machine front end is equipped with the pump housing, and pump housing both sides are respectively equipped with the water inlet 9 being connected with low pressure chamber and the water outlet being connected with high pressure chest
3, low pressure chamber and high pressure chest connect two groups of diaphragms 12 respectively, and eccentric wheel 15 is equipped on motor output shaft, drive connecting rod 14 and film
Piece moves up and down so that the volume of lower work chamber is constantly being reduced and expanded, and the suction of water feeding one-way valve 17 is opened, water is from intake antrum
Be inhaled into working chamber, fluid pressure raises during compression, and it is open-top to go out water one-way valve 16, and liquid is pressed into water chamber, liquid along
Water channel is ejected from water outlet.
The application thes improvement is that, water inlet medial end sets circular water suction accent 8, and accent is opposite is equipped with water suction
Cylindrical pressure regulating cavity 10, pressure regulating cavity are internally provided with relief piston 5, and relief piston is sealed along before and after pressure regulating cavity and is slidably connected, and adjust
Pistons end is pressed to be equipped with gasket 7, gasket is separated with water suction accent 8 and is tightly connected, absorbs water between accent and relief piston
Gap for water sucting cavity 19, water sucting cavity connection low pressure chamber, high pressure cavity outer wall is equipped with pressure port 4, the other end of relief piston with
High pressure chest is connected by pressure port, and relief piston connection makes water suction accent spring assembly separated with piston clearance.That is,
Outside liquid enters water sucting cavity by water inlet, afterwards into low pressure chamber, is discharged after compressed into high pressure chest by water outlet,
It is slided between high pressure chest and low pressure chamber and is equipped with relief piston, relief piston can be to water suction accent sealing, the pressure of spring assembly
Diaphragm pump operating pressure.
The relief piston can be only fitted to any position of the pump housing, while the accent position follower that absorbs water.But as preferred
Embodiment, as shown in Fig. 2, in the present embodiment, water suction accent is vertical with water inlet, and water suction accent is located at upper and lower two working chambers
Between, water suction accent and motor output shaft are coaxial, and operationally, water exit position is located at middle part, is shaken when can reduce work.
And for the ease of adjusting preset pressure, pressure regulating cavity is integrally formed with inlet and outlet, pressure regulating cavity forward gap
Low pressure chamber is connected, rear portion is equipped with rear cover 6, and the end of rear cover and pressure regulating cavity is equipped with gap, gap connection pressure port, and rear cover is opened
The pressure of contained spring device can be adjusted, facilitates and is used under the different situations of configuration.
Further, stepped hole is equipped in front of pressure regulating cavity, relief piston forepart coordinates with stepped hole, can be before stepped hole
After move, also for multidiameter structure, rear portion is slidably and sealingly connected with pressure regulating cavity at relief piston rear portion, and relief piston outer sheath is installed
There is a spring, the set pressure of spring is the operating pressure of diaphragm pump, and during normal work, relief piston is made with water suction accent in spring
There are gaps, the liquid of water inlet under to enter high pressure chest normal through low pressure chamber.
In order to further increase stability, the eccentric shaft end of motor is equipped with bearing, bearing fixed seat and pressure regulating cavity difference
Positioned at the both sides of inlet and outlet.
During utility model works, the high pressure cavity pressure of water pump can be conducted by pressure port and acted on relief piston,
Under normal conditions due to there is a resistance of pressure spring, piston is maintained at that initial position is motionless, and piston nose has gasket and and water sucting cavity
Mouth keeps certain distance, forms a water sucking mouth aperture.When the pressure rise of system is to the elastic force for overcoming pressure spring, piston
It can move forward, this distance can become smaller, and the reduction of water sucking mouth aperture can cause flow of inlet water to reduce, at this time single by intaking
The flow for entering working chamber to valve is accordingly reduced, and is caused the operating pressure of system and is reduced, and the system pressure of reduction can cause to make again
It is reduced with the pressure on floating piston, when the balance of power of this strength and pressure spring, piston no longer moves, water sucking mouth
Aperture no longer changes, and the pressure of system also no longer changes, so the pressure of system is not in big pressure oscillation, and it is straight at this time
Galvanic electricity machine instead can due to being lower of pump capacity, the constant corresponding input power of pressure decreases.
When the water outlet of water pump is closed suddenly, the pressure of system can be raised instantaneously, cause to act on relief piston
Strength sharply increases, and so as to which piston overpowers spring resistance quickly moves forward, the small gasket of piston nose also can be instantaneously bonded
In water suction accent end face so that water sucking mouth aperture completely encloses, and liquid is not entered back into the intake antrum of water pump, at this time due to water pump
Intake-outlet all close, pump motor is in idling conditions, and motor revolution electric current is very low at this time, input power very little.Work as water
When pump discharge reopens, be added in pressure behind relief piston and reduce, moved after piston, water suction accent is again turned on, water pump into
Water cavity is intake immediately, and water pump restarts in running order.
