Example Embodiment

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As mentioned in the background art, as the core component of the reverse osmosis water purifier, the tightness of the RO membrane filter element is particularly important to ensure the stable operation of the water purifier and the quality of the effluent. The existing tightness test of the RO membrane filter element mainly judges the tightness of the RO membrane filter element by passing water through the RO membrane filter ele...

Abstract

The invention discloses a testing device and a testing method for an RO membrane filter core. The testing device comprises the components of a fixing frame which is used for fixing the RO membrane filter core; at least one air ventilating valve; a vacuum pumping device; at least one negative pressure vacuum meter; and a control device which is connected with the vacuum pumping device, the air ventilating valve and the negative pressure vacuum meter. The control device is used for opening the air ventilating valve and making the vacuum pumping device supply negative pressure to the RO membrane filter core. Furthermore on condition that a fact that a pressure value which is fed back by the negative pressure vacuum meter is a first preset pressure value is acquired, the control device performs controlling for closing the air ventilating valve. Furthermore on condition that the pressure value which is fed back by the negative pressure vacuum meter is not lower than a second preset pressure value after a preset pressure keeping time period, the control device reminds a tester of a fact that the RO membrane is qualified and the second preset pressure value is not larger than the first preset pressure value. According to the testing device and the testing method, an existing water testing mode is replaced by a negative-pressure air testing mode. Simple testing device structure is realized, and furthermore a problem of bacteria contamination to the RO membrane filter core is prevented.

Description

technical field [0001] The invention relates to the technical field of RO (Reverse Osmosis, reverse osmosis) membrane filter elements, and more particularly, to a testing device and a testing method for an RO membrane filter element. Background technique [0002] Due to the pollution of water source water quality, the lag of water purification equipment and technology in urban water plants, the poor material of some pipe networks and internal pipes of users, poor management of roof water tanks, and the continuous improvement of people's requirements for water quality, many urban tap water users There is dissatisfaction with the quality of tap water. Although various localities have formulated plans to improve the quality of tap water, the transformation will take time. Therefore, choosing a household water purifier to filter impurities, bacteria, etc. is a beneficial measure to purify water quality and ensure health. [0003] The existing water purifier market is mainly div...
