Abstract

The invention relates to the technical field of water purification, and discloses a pump which comprises a pump body, wherein a water inlet flow passage, a water outlet flow passage and not less than one plunger piston hole are arranged on the pump body; a plunger piston is arranged in the plunger piston hole, a plunger piston stretching device is arranged at the upper end of the plunger piston, a first sealing part is arranged between the upper part of the plunger piston and the plunger piston hole, a second sealing part is arranged between the lower part of the plunger piston and the plunger piston hole, and a hollow plunger piston cavity is arranged between the first sealing part and the second sealing part; a water outlet valve is arranged at the bottom of the plunger piston cavity, awater inlet is arranged at the lower end of the plunger piston hole, and a water inlet valve is arranged at the water inlet; and the water inlet is communicated with the water inlet flow passage, andthe plunger piston cavity is communicated with the water outlet flow passage. The invention also discloses portable water purifying equipment.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a pump. The invention also relates to a water purification device having the pump described above. Background technique [0002] Portable seawater desalination equipment, bitter salt water desalination purification equipment, underground and surface natural water purification equipment, etc. are all called portable water purification equipment. [0003] Portable water purification equipment usually includes a filter tube and a filter element for purification. When the water to be purified enters the filter tube, it must have a certain pressure. Water under pressure is pumped into the filter tube. [0004] In the prior art, the pumps commonly used in portable water purification equipment are mainly plunger pumps, and the plunger pumps mainly include axial plunger pumps and radial plunger pumps. An axial piston pump is a plunger pump in which the reciprocating directi...
