2.Overview of Principle and Sructure
The hydro pressure-testing machine is a set of devices used to test the interior pressure of the fire
extinguisher (or the gas cartridge), and measure the ratio of permanent volumetric expansion of the cylinder through the interior pressurization test. It mainly comprises of an electric pressure test pump and an electric control device.
This machine has the advantages of mobility. The motor and reduction gearbox are installed on the water tank cap. Worm-wheel type reduction gearbox, and worm drive. The velocity ratio is 2:45. And there is an eccentric shaft on each side of the worm wheel, and they are 180º to each other. With the slider and crosshead inside the outer transmission gearboxes on both the side caps, they convert the rotary motion into reciprocating type rectilinear motion so as to achieve the alternative inhaling and disgorging process of the pump.
There is a 60Mpa pressure gauge with electric contacts installed on the top of the testing pump to set the controlled pressure arbitrarily. When the discharge pressure reaches the testing pressure, the pressure with electric contacts will send out signals, and the power of the motor will be switched off automatically. The record of the burette will reflect if the cylinder meets the requirements of the pressure testing.
Above the machine case handle, there is an electric control device, which has a startup button (green) and a stop button (red), by which you can control the operation of the testing pump manually. And there are fuses, AC contactors, etc. in the case.
