If the normal operation of the large flow pneumatic pressure test pump is related to the normal operation of the entire Machine, it plays an important role. If we learn how to determine the fault and find a solution, we can save a lot of time The necessary time and financial resources, the following describes the next high-flow pneumatic pressure test pump failure and its solution. Fault 1, the pressure gauge to reflect uneven pressure rise or pressure gauge pointer does not swing. Reason: 1, out of water valve does not affect the flow, pressure gauge is not normal. 2, inlet filter is blocked, or pipe connections leaks. 3, water tank is too low or unclean water. 4, the plunger at the filler leaks. Solution: 1, open the inspection, or grinding out of the valve to make it tight. 2, remove the filter or eliminate leakage. 3, improve the water tank height or exchange of clean water. 4, packing is too loose, should be adjusted, if damaged, to be replaced. Fault 2, the required power is too large. Reason: 1, the plunger seal packing is too tight. 2, the plunger has been bent, interfere with the water tank. 3, low-pressure water tank pressure has exceeded the provisions of the return valve is not opened in time. 4, poor contact with the worm and the wheel, displacement or hey hair 5, poor lubrication of the conductor and the slider, hey wool or abrasions. 6, gearbox oil less, or lubrication of lubricants bad condition. Solution: 1, appropriate relaxation. 2, check and correct it. 3, in time to open the return valve. 4, for maintenance. 5, should be amended. 6, timely replenishment of oil. Fault 3, the water pressure changes. Cause: There is no air in the cylinder. Solution: Open the cylinder valve and the air vent to adjust the bottle water level. Fault 4, gearbox oil overheating. Reason: 1, lubricant is not suitable. 2, too much oil 3, the oil is dirty. Solution: 1, should be replaced by lubricating oil. 2, lower the oil level to the oil level. 3, exchange new oil. Fault 5, safety valve leakage. Reason: 1, the valve cone tightness bad. Solution: Grind the valve top cone so that it fits well. The above is a small series of all the large flow pneumatic pressure test pump troubleshooting and its possible solutions, I hope to give you some help, follow-up and then encounter similar problems when the problem can find their own time to find the appropriate solution method.
