The high-pressure self-suction pump is composed of four highly sealed cavities which do not interfere with one another and are mutually connected in a seamless mode, the work efficiency is high, work pressure is high, secondary pollution of the water pump is basically avoided, and the high-pressure self-suction pump is high in application range. A pressure relief valve is designed at a pump head, when pressure is higher than set pressure, the water pump automatically relieves pressure, and overload protection is achieved. A key element of a pump body, namely a diaphragm is made of high-tenacity food-grade rubber, and the diaphragm is highly resistant to abrasion and long in service life. Sealing ribs are designed on the four cavities of the pump body, the four cavities are mutually independent and highly sealed, the four cavities are similar to four independent diaphragm pumps and share one water inlet/outlet, and therefore the defect of intermittent work of a diaphragm pump is well overcome. The high-pressure self-suction pump is reasonable in arrangement layout, well resolves the resonance defect of the pump body, improves the efficiency of the pump, and is low in power consumption and low in noise. The noise is not higher than 50 db under high-pressure load, and is not higher than 40 db under no load.

Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, high pressure self prime pump, comprise the motor 18 that is arranged on bottom, described motor arranges rubber fastening foot 19, and this rubber fastening foot 19 can reduce the vibrations noise of electric machine rotation, on motor 18 heads, rear end cover 17 is set, motor 18 heads arrange eccentric wheel 16 after stretching into rear end cover 17, described eccentric wheel 16 arranged outside ball bearings 15, install swing link bracket 14 at eccentric wheel 16 tops, and described eccentric wheel 16 drives swing link bracket 14 to swing up and down; Described swing link bracket 14 is fixed by the fixed base 13 coordinating with it, and described fixed base 13 is arranged on rear end cover 17, and within eccentric wheel 16, ball bearing 15 and swing link bracket 14 are encapsulated in to described fixed base 13 and rear end cover 17; Described fixed base 13 upper ends arrange barrier film 12, and at the interior barrier film fixed plate 11 that arranges of barrier film 12, described barrier film 12, barrier film fixed plate 11 form Seal cage; Water inlet valve block 10 is set on barrier film fixed plate 11, described water inlet valve block 10 is through ventilation seat 9, described ventilation seat 9 is fixed on barrier film 12, at ventilation seat, 9 central authorities set out hydroecium, described Seal cage and UNICOM of water-supplying chamber, in water-supplying chamber, set out water valve plate 8, in the time that water inlet valve block 10 is closed, water outlet valve block 10 is opened; Between described water outlet valve block 8 and water-supplying chamber, seal ring 7 is set, install end cap 5 in ventilation seat 9 upper ends, described upper end cap 5, barrier film 12, fixed base 13 and rear end cover 17 are combined fixing by screw, between described ventilation seat 9 and upper end cap 5, sealing gasket 6 is set, described Seal cage is provided with 4, and independent separately, each Seal cage respectively separately with UNICOM of water-supplying chamber.Described upper end cap 5 is provided with pressure releasing valve core 4, between described pressure releasing valve core 4 and decompression cover 1, is connected by spring 3, between described pressure releasing valve core 4 and water outlet valve block 8, certain gap is set.Between described decompression cover 1 and described upper end cap 5, be provided with Decompression valves seal ring 2.
The working principle of this device is as follows: water pump is under the drive of DC24V direct current generator, by rotatablely moving of motor, become swinging up and down of swing link bracket 14 and drive barrier film 12 to pump by eccentric wheel 16, and form the pull of vacuum of four active chambers by the opening and closing of water inlet valve block 10, water outlet valve block 8, the water of water-inlet cavity is inhaled into and is forced into water chamber by active chamber.Motor 18 revolves four active chambers that turn around and all completes a work cycle like this, liquid (or gas) is by upper end cap water inlet (gas) mouthful, by water inlet valve block, circulation enters four Seal cages, while often entering next chamber, last active chamber inlet valve is closed, and outlet valve is opened, and is discharged by upper end cap water outlet.Four cavity periodic duties, so this pump is gapless work, efficiency is very high, is four times of common self-priming pump.Motor continuously turns round, and four active chambers of water pump just continuously move in circles and suck and discharge water, and water pump just draws into continuous flow not.The working procedure of Decompression valves: set after certain cracking pressure and (determined by pressure limiting spring force) when water pump Decompression valves, in the time that the induced pressure in water pump water outlet chamber rises to the tension force that is greater than pressure release spring, pressure releasing valve core is backed down by water chamber pressure, water chamber has a small amount of water to flow to return flow line to water-inlet cavity through relief hole, at this moment water chamber pressure decreased, the opening to maintain under induced pressure balance of outlet valve worked, and flow also reduces thereupon; Induced pressure is larger, and pressure releasing valve core is opened just larger, and spool valve is just broken original balance, more under high capacity pressure balance, is working, and water outlet flow reduces more; And while increasing to not water outlet of water outlet shutoff to induced pressure, Decompression valves is opened completely, the water that at this moment water-inlet cavity sucks all flows back to through Decompression valves the water-inlet cavity that puts in place, and water pump is worked under the highest earial drainage pressure.Water pump and load system have been subject to overload protection like this.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
