Abstract
The utility model discloses a diaphragm pump, which belongs to the mechanical technical field and comprises a pump body, a cylinder structure, a crankcase, a crank, a pressure regulating valve, a pump bonnet, a water feeding and discharging valve, a pressure indicator and a connector component connected with the external pipeline; wherein, the cylinder structure is formed in such a way that a connecting rod is inserted in a piston through a shaft and connected with the hole of the connecting rod; the outer circumference of the piston is connected with a sealing ring; the piston matches with a piston sleeve; one end of the piston sleeve is provided with a rubber diaphragm; the rubber diaphragm is fixed on the piston through a cover and a bolt. The rubber diaphragm is arranged on the top of the piston of the pump to separate the oil storage cavity in the pump from the liquid conveying cavity, therefore the transmission piece in the pump throughout runs under the lubricating condition by good worm. After the diaphragm pump is improved, the oil and the water are separated and the water and the pump are separated. The pump has the special performance capable of dewatering and idling to bring the convenience for user.
Description
Technical field
The utility model relates to a kind of diaphragm pump.Belong to field of mechanical technique.
Background technique
The septum primum membrane pump water inlet and outlet and the pump housing combine.After pump used, water channel had seepage.Whole diaphragm pump will be scrapped Aggravate peasant's burden.
Summary of the invention
In view of the above problems, the purpose of this utility model is to provide a kind of diaphragm pump.
A kind of diaphragm pump of the utility model is made up of the pump housing, cylinder structure, crankcase, bent axle, pressure regulator valve, pump cover, turnover water valve, pressure indicator and the joint component that connects extraneous pipeline; Cylinder structure is connected for connecting in the hole of pavilion by axle reeve piston and connecting rod, and the excircle of piston has seal ring to connect, and piston is engaged in the piston sleeve, and an end of piston sleeve has diaphragm of rubber, and diaphragm of rubber is by covering and being bolted on the piston.
Piston head at this pump is equipped with diaphragm of rubber, and pump internal memory oil pocket and transfusing chamber are separated, and the pump inner driving medium is turned round under the lubricating condition of good insect all the time, so this pump has the special performance of the no load running of dewatering, brings convenience to use.
Because six cylinders of this pump are arranged, make pump remain uniform imbibition and discharge opeing in movement process, so the discharge pressure of this pump are comparatively stable.
The utility model discloses a kind of diaphragm pump is a kind of novel equipment for plant protection and the disinfecting pump of developing according to advanced foreign technology; has the working pressure height; discharge pressure is stable; flow is big; corrosion-resistant; compact structure is reasonable, operation and maintenance is convenient, the no load running of dewatering, characteristics such as applied widely.It can be supporting with multiple power equipment (as motor, diesel engine, petrol engine, tractor, automobile etc.), forms the atomizing sprayer and the atomizing sprayer of various types.Be widely used in the prevention and control of plant diseases, pest control of floods and droughts field, orchard, forest and city trees and shrubs and spray liquid chemical fertilizer and weed killer; also can be used for small-sized farmland discharging-irrigating, high mountain diversion and under ground piping spray medicine in some mountain area and rolling country; also can be used for industrial fields such as vehicle cleaning, disinfecting, chemical industry transfusion, environmental protection, is present domestic novel desirable industrial or agricultural pump.
The utility model major advantage:
1, improve back oil-water separation, water separates with the pump housing;
2, alleviate user's burden.
Description of drawings
When considered in conjunction with the accompanying drawings, by the reference following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide further understanding of the present utility model, constitute a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute to improper qualification of the present utility model, wherein:
Fig. 1 is that expression is as structural representation of the present utility model.
Embodiment
With reference to Fig. 1 embodiment of the present utility model is described.
A kind of diaphragm pump of the utility model is made up of the pump housing, cylinder structure, crankcase, bent axle, pressure regulator valve, pump cover, turnover water valve, pressure indicator and the joint component that connects extraneous pipeline; Cylinder structure is for being connected in the hole that connects pavilion 1 and inject pistons 2 and connecting rod 1 by axle 3, and the excircle of piston 2 has seal ring 4 to connect, and piston 2 is engaged in the piston sleeve 5, and an end of piston sleeve 5 has diaphragm of rubber 6, diaphragm of rubber 6 by cover 7 and bolt 8 be fixed on the piston 2.
The pump housing, crankcase, bent axle, pressure regulator valve, pump cover, turnover water valve, pressure indicator and the joint component that connects extraneous pipeline are prior art.
The utility model is that above-mentioned structure cylinder is furnished with six and is distributed on the pump housing.
At piston of the present utility model 2 tops diaphragm of rubber 6 is housed, pump internal memory oil pocket and transfusing chamber are separated, the pump inner driving medium is turned round under good lubricating condition all the time,, bring convenience to use so the utlity model has the special performance of the no load running of dewatering.
When driving crankshaft rotating promotion connecting rod piston, power does reciprocating linear motion, piston 2 pulling diaphragm of rubber 6 by top dead center when the lower dead center direction is moved, cavity volume between diaphragm of rubber 6 and pump cover forms vacuum, thereby make liquid under the barometric pressure effect by the flow of inlet water in the pump housing, open inlet valve and enter the pump cover inner chamber, when promoting diaphragm of rubber 6, piston 2 begins when up by lower dead center, liquid in the pump cover is subjected to the extruding of piston 2 and diaphragm of rubber 6, inlet valve is closed, liquid is pressurized in the pump cover, highly pressurised liquid is opened outlet valve and is entered rising pipe, when piston 2 walks to top dead center, discharge opeing finishes, and outlet valve is closed, and piston 2 repeats a preceding cyclic process again when descending.
Because six cylinders of this pump are arranged, make pump remain uniform imbibition and discharge opeing in movement process, so the discharge pressure of this pump are comparatively stable.
Obviously, the many modifications and variations done based on aim of the present utility model of those skilled in the art belong to protection domain of the present utility model.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from inventive point of the present utility model and effect in fact can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
