Blowing Sand Test Chamber / Laboratory Sand Test Equipment 7000 X 5000 X 2500mm

Blowing Sand Tester KP-SCJB1000

Purpose

Sand(150um ≤ sand diameter ≤ 850um) procedure. This test is performed to help evaluate the ability of materiel to resist the effects of dust that may obstruct openings, penetrate into cracks, crevices, bearings, and joints, and to evaluate the effectiveness of filters

Reference standards

MIL-STD-810G.

Design principles

Its structure is a funnel,a collecting hole for dust on the bottom,on the right side of this hole is equipped with a suction inlet of turbine circulating fan.Send the pumped dust into the bottom of inner chamber and then to the left side and go upwards;blow the dust into test chamber from the left side; the dust should be blown rightwards in a horizontal direction and then begin circulation.
