Hand pump overview
? This type of hand pump pump liquid temperature below 60 ° C (refers to the cup pump). Its performance range; flow rate is 15-59 liters / min, the maximum lift is 30 meters. This type of hand pump is compact in structure, beautiful in appearance, easy to use and reliable. The pumps currently manufactured include S-25, S-38, SH-25 and SH-38.
The meaning of the pump model: such as BSSS type hand-washing water pump, BSYY type hand-cranked oil pump
SS- is a bowl type, suitable for sucking water
YY- is piston type, suitable for sucking oil liquid
38- is the suction and discharge diameter of the pump in millimeters
Structure description
The structural principle of this type of pump is that when the rocker handle (29) is reciprocated by hand, the piston (7) is made through a transmission mechanism such as a shaft (21), a rocker arm (9), and a connecting rod (36).
Reciprocating motion. As shown in the figure, when the piston moves to the left, the pump cylinder at the right end gradually expands to form a vacuum, and the liquid is cast from the suction pipe (34) to the side of the pump body.
The suction passage opens the suction valve into the right end of the cylinder. At the same time, due to the compression of the piston on the left side of the cylinder, the pressure valve (5) is opened and the liquid is discharged through the discharge pipe (11).
discharge. If the direction of movement of the piston returns to the right, the liquid is sucked into the left side of the pump cylinder, and the liquid is discharged to the right side of the pump cylinder, so that the liquid is sucked in and out without interruption. shape
Work into a pump. The upward stroke of the pump's pressure valve is limited by the cover plate (6), and the upward stroke of the suction valve is limited by the pressure valve. The cover plate and the pump body are fastened with bolts (8), and the piston row
The process is limited by the pump cover (14) and the pump body. For mounting on a wall or other foundation, the pump body has three bolt holes
