Problems solved by technology

Two first springs and two second springs are used in this structure. The spring force and the friction force of the mechanism will affect the position of the piston when reversing. Due to the inevitable tolerance in the spring production and the friction force of the mechanism, there is a certain range. distribution, resulting in inconsistencies in the stroke of the piston in the booster pump, and the quality of the product is not easy to control

Abstract

The invention discloses an energy storage device and a booster pump using the device. The energy storage device comprises a stop sleeve with a fixed position, a slide pin coaxially arranged with the stop sleeve and capable of sliding in the axial direction of the stop sleeve, and a pushing piece embedded in the stop sleeve and capable of sliding in the axial direction of the stop sleeve; the pin sleeve is elastically butted against the stop sleeve; and the pushing piece is stressed to bend and push the pin sleeve. The energy storage device has the following beneficial effects: the energy storage device is simple in mechanism; all parts are arranged on the same one straight line; and the tolerance for the parts is high.

Description

technical field [0001] The invention relates to the technical field of production of household pure water treatment equipment, and more specifically relates to an energy storage device and a booster pump using the device. Background technique [0002] The energy recovery device is a key device of the reverse osmosis system, in which the differential pressure recovery method can directly increase the pressure of the incoming water in a multiple relationship. Patents CN101581328A, CN102060354A, US5628198A, and US7175395A all involve this aspect. In this type of device, the piston type reciprocates, and the automatic reversing mechanism that controls the movement of the piston is the key. [0003] Patent CN102330648B discloses a booster pump mainly used in household water purifiers, which is essentially a differential pressure energy recovery device. In this patent, a spring is used to store energy when the piston moves, and when it reaches a certain position, the mechanism i...
