A four-pump-head plunger metering pump
By designing a four-pump-head plunger metering pump, each plunger completes one pumping cycle with one rotation of the cross crankshaft. Combined with elastic rubber blocks and flexible rings to eliminate vibration, this solves the problem of loose liquid pipes caused by large vibrations in traditional plunger pumps, achieving high-frequency and stable metering.

Abstract
The utility model relates to the technical field of metering pump, specifically pump head four plunger type metering pump, it includes: base, the top of base is equipped with drive main body, drive main body is connected with base through first elastic rubber block, and drive main body is cavity structure, and opposite two ends are equipped with shaft hole respectively, and opposite two sides are equipped with drive window respectively, and one end of drive main body is equipped with speed reducer motor, and speed reducer motor is connected with base bottom through second elastic rubber block, cross crankshaft, cross crankshaft sets up in drive main body, and four curve hammers that are apart 90 degrees are sequentially equipped along the length direction, pump body, distributes in the both sides of drive main body, and each pump body is equipped with a pair of plunger respectively corresponding drive window, and each plunger is matched with corresponding curve hammer through connecting rod respectively. The utility model realizes to complete once pumping work per 90 degrees of rotation through the included angle setting of each curve hammer, thereby has improved the density of pumping frequency, has realized to reduce the working speed, has reduced the vibration.
