Improvement of damping structure and swing wheel structure of four-booster-cavity diaphragm pump

Abstract

The invention relates to an improvement of a damping structure and a swing wheel structure of a four-booster-cavity diaphragm pump. A cambered concave groove is downwards and concavely formed in the top face of a pump head seat in the four-booster-cavity diaphragm pump and surrounds the periphery of each acting through hole, and a cambered convex block is arranged downwards and convexly in the position, corresponding to each cambered concave groove, in the bottom face of a diaphragm sheet, so that small force arm lengths are formed between the cambered convex blocks and positioning convex rings at the bottom face of the diaphragm sheet, moment produced by a pump body during acting of the pump body becomes smaller, and the intensity of 'shakes' is further greatly reduced; besides, the region from a positioning concave ring groove in the horizontal top face of each cylindrical swing wheel of a swing wheel base to the vertical side face is arranged to be a downward inclined face, so that the loss of 'extrusion' to the bottom face of the diaphragm sheet during acting of the four-booster-cavity diaphragm pump cannot be produced.

Description

technical field [0001] The present invention is related to a diaphragm booster pump installed in a reverse osmosis water filter (reverseosmosispurification), or used in a bathroom kitchen water supply equipment in a recreational vehicle (recreationalvehicle), in particular to a pump that can greatly reduce the vibration intensity when the pump body is in motion. structure, so that after it is installed on the casing of the reverse osmosis water filter or the bathroom and kitchen water supply equipment in the caravan, it will not resonate the casing and cause annoying noises, and the cylindrical balance wheel structure of its balance wheel seat Improvement, so that the pump body will not "squeeze" the bottom surface of the diaphragm when it is in motion. Background technique [0002] Currently used in the reverse osmosis water filter and the dedicated four-boost chamber diaphragm pump for the bathroom and kitchen water supply equipment in the traveling caravan, except that it...

Problems solved by technology

[0005] Therefore, if Figure 16 As shown, a conventional diaphragm pump with four pressurization chambers is equipped with a base 100 on the outer edge of the pump body, and a pair of rubber shock absorbing pads 102 are respectively set on the two side flanges 101 of the base 100, and then fixed screws 103 and screws The cap 104 fixes the base 100 to the reverse osmosis water filter, or the casing C of the bathroom and kitchen water supply equipment in the caravan; The effect of the shock is quite limited, because the "vibration" intensity generated by the action of the pump body is extremely large, it will still cause the resonance of the shell C and send an annoying sound. In addition, the water pipe P connected to the pump head cover 20 water outlet 22 is also It will vibrate synchronously with the frequency of "vibration" (such as Figure 16 As shown by the imaginary line P in view a) and hit other components in the adjacent reverse osmosis water purifier, if used for a period of time, the water pipe P and its joint will gradually become loose due to shaking The phenomenon will eventually lead to the result of water leakage. Many of the above defects are caused by the "vibration" generated by the operation of the four-increase-chamber diaphragm pump. "The lack of it has become a very urgent issue to be solved
