Abstract

The utility model discloses a take sealing rib's diaphragm chamber, including high pressure chest and low pressure chamber, it has the multiunit wash port to distribute in the high pressure chest, and the periphery in every copy cast water hole is provided with sealing rib. The utility model discloses a take sealing rib's diaphragm chamber makes the face seal into linear sealing through sealing rib, increases sealed degree, reduces sealed face and goes up deposit dirt, impurity, and the microorganism goes up the influence of growing and bringing the leakproofness at sealed face even, does when absorbing water the action at utmost in the low pressure chamber from the water storage chamber and prevents the water under high pressure against the current to low pressure chamber, improvement pump drainage efficiency.

Description

With the chamber of septum of sealed muscle

Technical field

The utility model belongs to reverse osmosis suction booster field, specifically a kind of chamber of septum with sealed muscle.

Background technique

Existing reverse osmosis boosting pump structure, its structure is presented as that chamber of septum has low-pressure cavity, hyperbaric chamber and water storage cavity, and hyperbaric chamber is concavity sphere, is distributed with weep hole, discharge safety check and be positioned at hyperbaric chamber, and surround weep hole, low-pressure cavity is distributed with suction hole, and inhalation check valve covers suction hole, under the effect of the escapement of driven by motor, the water of water storage cavity sucks low-pressure cavity after suction hole, and setting-out, to hyperbaric chamber, is discharged by hyperbaric chamber.

When low-pressure cavity does water suction action from water storage cavity, discharge safety check can only cover weep hole ideally and seal it, and this sealing is face sealing, easily occurs revealing; After suction booster long-time running, discharge meeting dirt deposits, impurity on safety check, microorganism grows on the sealing surface of discharging safety check even, sealing surface is caused to be not closed completely, in low-pressure cavity water absorption course, comparatively early occur that high pressure water adverse current returns low-pressure cavity, affect pump drainage efficiency.

Model utility content

In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of chamber of septum with sealed muscle, comprises hyperbaric chamber and low-pressure cavity, and be distributed with in described hyperbaric chamber and organize weep hole more, the periphery often organizing weep hole is provided with sealed muscle.

Further, the height of described sealed muscle is 0.2-0.7mm.

The chamber of septum of band sealed muscle of the present utility model makes face sealing into linear sealing by sealed muscle, increase tightness, reduce dirt deposits, impurity on sealing surface, microorganism grows the impact brought sealing on sealing surface even, at utmost stop high pressure water adverse current to low-pressure cavity when low-pressure cavity does water suction action from water storage cavity, improve pump drainage efficiency.

Accompanying drawing explanation

Fig. 1 is the structural representation of the chamber of septum of band sealed muscle of the present utility model;

Fig. 2 is the chamber of septum sectional view of this band sealed muscle.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As illustrated in fig. 1 and 2, the chamber of septum of band sealed muscle of the present utility model, comprises hyperbaric chamber 1 and low-pressure cavity 2, and be distributed with many group weep holes 3 in hyperbaric chamber, the periphery often organizing weep hole 3 is provided with sealed muscle 4, and the height of described sealed muscle 4 is 0.2-0.7mm.

Check experiment

In order to the sealing effect checking the convex arranging sealed muscle to discharge the discharge safety check of safety check and prior art, following experiment is set.

Test condition:

Dry state self-priming is tested: normal temperature 25 °, and pump head inside is anhydrous, water outlet access pressurized gas;

Air leakage: normal temperature 25 °, pump head inside is anhydrous, water outlet access 0.2Mpa pressurized gas, in the water that submerged by entery and delivery port 1 minute, measures number of bubbles.

Working state

Voltage: 24v water outlet pressure: 0.5Mpa; Shutoff water outlet;

Testing apparatus:

DC power supply, air leakage detector, suction lift testing apparatus, three industry control test platforms, measuring cup, Chronograph, noise instrument, turbidimeter, omnipotent pressure test machine, digital display thermostat water bath, Shore durometer.

Test result:

For the first time:

For the second time:

For the third time:

Visible, after changing the chamber of septum of band sealed muscle of the present utility model, the sealability of hyperbaric chamber improves greatly, and because moulding different batches product exists change in drain opening local, after using the chamber of septum of this band sealed muscle, the conformity of batch performance improves simultaneously greatly.

Claims
