What's the working method of the valve for a screwdriver
The entry valves consist mainly of valves, valves, pistons, cylinders, springs, seals, etc., with control blocks on their sides and control of electromagnetic valves, which combine the functions of decomposition, reduction, silence, decompression and decommissioning. A small portion of the gas is released through a small hole in the valve to balance the inhaled gas in the small hole of the intake control valve to maintain pressure in the separate tank at 0. 2-0. 3 mpa and maintain normal air compressor cycle. The opening-off action of the inflow control valve is automatically controlled by the pressure sensor and the electromagnetic valve of the regulating system, and the flexibility of the opening-off action of the input control valve is important for the reliability of the screwdriver。
The failure of the entry valve is typically the failure of the screws to unload and the failure of the entry valve to close. Unmounted, electromagnetic valves of the imported valve are damaged. Sprayer oil, valve control block failure. The screws are overloaded and the input valves are opened early at start-up. Therefore, the inflow control valves should be periodically replaced to maintain good working conditions. During each maintenance, the parts shall be removed, the wear and tear of each friction surface shall be checked, in particular the rubber seal surface shall be inspected and, in case of damage or crack, new items shall be replaced, the parts shall be cleaned and the friction surface of the metal parts shall be coated with lubricant when replacement of the repair kit is completed。
The description of the general air pressure plant provides for the replacement of the valve repair kit for 8,000 hours, but in order to reduce costs, some users would hardly have been able to maintain it in accordance with the life cycle, until the valve failed and then repaired it. Therefore, it is recommended that the proper time for replacement would be possible for users to do so within the prescribed time frame, since each machine is operating in a different environment and is best managed to replace it within a reasonable range。
A spiral air press is actually a device for compressing air. It is a revolving volume compressor, with a single power connection and a single compressed air connection, with a cooling system in place and a simple installation. So what's the work and composition of the screws?
It's the pyrocardic principle of a screwdriver
A general pattern for a propeller air-voltage valve is that the pump valve is charged and unloaded. Sometimes our equipment has a slightly larger current when it's offloaded, and the 22kw is offloaded with 31a. The initial suspicion is that the entry valves are not closed, because when the gas is not used, the pressure will slowly rise and sometimes the alarms will stop! Also, after the shutdown, there were residual pressures within the machine that could not be unloaded (around 6 kg), resulting in the host being overloaded when it was re-started。
When the piping machine enters a gas valve that is open, the piping machine is open when it is not loaded, and when the compressor is loaded it is closed. When the electromagnetic valves are opened, there will be a trail of gas to shut down the input valves, but they will not be completely shut down, and they will be kept in the breathing space to maintain the minimum pressure required for compressors to lubricate, which is usually at 1. 5bar; when the electromagnetic valves are closed, the compression opportunity enters normal working conditions until the established working pressure, depending on the user. The entry valve has two ducts and is empty all the way; it is free of the respiration of the valve and ensures that the compressor is loaded properly. When offloading, the current is excessive, indicating that the tank pressure is high and the valve is open. Please adjust to empty bolts to ensure that the tank pressure is not too high。
When the engine is shut down, the canal pressure will normally be completely empty in 60 seconds, or zero. And your jar pressure is still 6 bar, which points to the problem of emptying the valve:
1 may be the diameter of the pipe;
2. Combination valves are too small or muzzled。
When offloaded, the pressure rises slightly, but this is only a balancing requirement and for a short period of time. It won't go up to the high-pressure shutdown. The high-voltage shutdown should be a problem with the air-voltage machine's electromagnetic valve, and please check if it is complete and can work properly。
