Product features: small hand pumps, high pressure hand pump light weight, compact, simple operation, high pressure, low flow ... 1. Started before the test pump should be carefully checked whether parts joints tighten pressure gauge is normal, out of the pipe is installed, this pump working medium is 5 ~ 50 ℃ [1] of water, an emulsion or a kinematic viscosity <45mm2 / s of oil. Prohibit the use of contaminated sediment and other debris unclean water. 2. In order to improve the efficiency of the pressure test, the test vessel can first be filled with water or equipment first, followed by pressure test pump outlet pipe. 3. In the pressure test process, if found how the amount of water the air can be screwed open the valve, the air let go. 4. In the pressure test process, if there is any minor leakages should be immediately stopped for inspection and repair, is prohibited under the water seepage continue to increase pressure. 5. After the pressure test is finished syb hand pump, first loosen the valve, the pressure drops, so as not to damage the gauge. 6. Test pump when not in use, put the best water in the pump, inhaling a small amount of oil to prevent corrosion.
