Abstract
The invention discloses a diaphragm pump, which consists of a pump body, a pump cover, an eccentric shaft, a connecting rod diaphragm pump, a water outlet valve and a water inlet chamber, wherein the water inlet chamber is provided with a water inlet valve. The diaphragm pump is characterized in that: a bearing is sleeved on the shaft journal of the eccentric shaft; six connecting rod are rotationally connected to the eccentric shaft through the bearing, and are uniformly distributed on the shaft journal of the eccentric shaft; when the six connecting rods project and descend at one time, the projecting space is reduced, pressure is produced, a reverse water inlet valve is closed, and a forward water outlet valve is used for draining pressure water; and when the connecting rods descend, the water outlet valve is closed under the action of produced negative pressure, and the water inlet valve is opened simultaneously for feeding water circularly. Compared with the prior art, the diaphragm pump has the advantages that: a plurality of connecting rods are arranged, so that the period density is high, the pressure fluctuation is small, a diaphragm is prevented from being damaged easily, and the diaphragm pump runs smoothly; and meanwhile, the connecting rods are rotationally connected to the eccentric shaft through the bearing, so that the defect of direct friction between the connecting rods and the eccentric shaft is overcome, the service life of the entire pump is prolonged, the replacing time of lubricating oil is reduced, and the power consumption is lowered.
Description
Technical field
The present invention relates to a kind of diaphragm pump, the six cylinder diaphragm pumps that especially a kind of connecting rod is rotatably connected with eccentric shaft through bearing.
Background technique
At present, the diaphragm pump that uses on the sprayer is four cylinder diaphragm pumps, and connecting rod directly is rotatably connected with eccentric shaft.This diaphragm pump, four suction water of main shaft revolution, pressure surge is big, and spray effect is poor; Piston is fast toward complex transformation, vibrations are big, and barrier film is fragile.Therefore, design six suction water of a kind of main shaft revolution, pressure surge is little, and spray effect is good, piston is slow toward complex transformation, vibrations are little, and six cylinder diaphragm pumps of barrier film long service life are the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides six suction water of a kind of main shaft revolution, and pressure surge is little, and spray effect is good, piston is slow toward complex transformation, vibrations are little, six cylinder diaphragm pumps of barrier film long service life.
The technological scheme that the present invention solves its technical problem is:
A kind of diaphragm pump is made up of the pump housing, pump cover, eccentric shaft, connecting rod barrier film, outlet valve and intake chamber, and intake chamber is provided with inlet valve; On the axle journal of eccentric shaft, be set with bearing, described connecting rod is rotatably connected on eccentric shaft through bearing, and the quantity of connecting rod is six; Six connecting rods are distributed on the axle journal of eccentric shaft, and are once protruding when six connecting rods, fall, the protruding time space generation pressure that diminishes; Reverse inlet valve is closed, outlet valve head pressure water forward, and the negative pressure that produces when connecting rod is fallen is closed outlet valve; Open water intake valve simultaneously, move in circles.
Compared with prior art, because connecting rod quantity is many, cycle density is high, and pressure surge is little, and barrier film is not fragile, the diaphragm pump stable working; Again because connecting rod is rotatably connected on eccentric shaft through bearing, substitute the drawback that connecting rod is direct and eccentric shaft rubs simultaneously, reduced the oil change time in working life of having improved complete machine, reduced power consumpiton.

Embodiment
Shown in Fig. 1-2, a kind of diaphragm pump is made up of the pump housing 4, pump cover 1, eccentric shaft 3, connecting rod 2 barrier films 6, outlet valve 5 and intake chamber 7; Intake chamber 7 is provided with inlet valve, it is characterized in that: on the axle journal of eccentric shaft 3, be set with bearing, described connecting rod 2 is rotatably connected on eccentric shaft 3 through bearing; The quantity of connecting rod 2 is six, and six connecting rods are distributed on the axle journal of eccentric shaft 3, and is once protruding when six connecting rods, fall; The protruding time space generation pressure that diminishes, reverse inlet valve is closed, outlet valve head pressure water forward; The negative pressure that produces when connecting rod is fallen is closed outlet valve, opens water intake valve simultaneously, moves in circles.
