Introduction: VAJ series products belong to the “Tianying” brand, which is an economical product of our company. It is inferior to the “Qihai” brand products in terms of life parameters, but its quality is excellent in the category of brush motor pumps. Far higher than other brush motor pumps. Non-polluting transmission, maintenance-free; can be installed in any direction; allows the medium to be rich in water vapor; can run continuously for 24 hours; small volume, low energy consumption. Widely used in handheld instruments, gas analysis instruments, etc. Allows the extraction of corrosive gases (gas contact materials: syndiotactic polystyrene resin, EPDM rubber). Features: Model VAJ850.4 Working voltage (V DC) 5 Load current (mA) <100 Flow rate (L/min) Peak flow 0.4 Average flow rate 0.4 Relative vacuum (kPa) ≈-16 Instructions for use: 1, the working environment of the pump: Ambient temperature: 0 ~ 50 ° C (no condensation), the pump should not be exposed to outdoor sun, should work in a clean and non-corrosive environment. Relative humidity of environment ≤90% 2. Working medium of the pump The gas drawn by the pump must be free of solid particles, but it is allowed to be rich in water vapor; the extracted gas will come into contact with EPDM rubber. And syndiotactic polystyrene resin (SPS), these two materials have certain corrosion resistance, please further judge the pump pair according to the contact materials. Tolerance of the extracted gas. Allowable medium gas temperature range: 0 ° C ~ 50 ° C 3, filtering problems When the pump is operated for a period of time, the dust contained in the pumped gas will accumulate inside the pump chamber, damaging the air tightness of the pump. The flow rate and vacuum are reduced, and a filter must be provided at the end of the suction port. Practice shows that we generally think it is very clean There are still dust impurities in the gas, and filtration is also required to ensure that the precision airtight components inside the pump work properly.
