Powder compaction testing machine for portable fire extinguisher

Abstract

The invention relates to a powder compaction testing machine for a portable fire extinguisher. The powder compaction testing machine is characterized by comprising vertical frames which are corresponding to fire extinguishers in a one-to-one manner and are used for allowing the fire extinguisher to move up and down therein; the vertical frame is disposed on a bed board of a rigid testing bed; the bottom of the rigid testing bed is provided with a connecting part fixedly connected with a ground base; ejector pins are arranged corresponding to the fire extinguishers in a one-to-one manner; the tops of the ejector pins are working ends; the bottoms of the ejector pins are fixed on the same plate capable of moving up and down; the height of every fire extinguisher ejected by the ejector pins is equal to or smaller than the strokemm of the ejector pin; the bottom surface of the plate capable of moving up and down is fixedly connected with a movable guide pillar; a movable guide hole matching with the movable guide pillar is disposed on a fixed supporting plate; the movable guide pillar is driven by a cam; and a servo motor drives the can to rotate. The Powder compaction testing machine also comprises a programmable controller (PLC), a motor speed controller and a counter which are controllably connected with the servo motor through control wires. The testing machine can meet powder compaction tests and meet the requirements of detection standards.

Description

technical field

[0001] The invention relates to the technical field of fire extinguisher detection equipment, in particular to a portable fire extinguisher powder compaction test device. Background technique

[0002] For portable, refillable, and powder fire extinguishers, a powder compaction test should be carried out to check whether the powder fire extinguishing agent is agglomerated and whether it can keep flowing at any time to ensure that the fire extinguisher can be sprayed normally. The current new standard is: for this test, the number of each batch of tests is not less than 3 fire extinguishers. The test method is: the fire extinguisher is dropped from a height of 15mm to a rigid horizontal iron plate at a frequency of 1Hz in the vertical direction for 500 consecutive times. . But there is no dedicated test equipment. Contents of the invention

[0003] In order to solve the above problems, the present invention provides a portable fire extinguisher powder compa...
