Check the vacuum at engine idle speed. This makes it possible to eliminate the possibility of insufficient power due to wear of the piston assembly, poor valve sealing, and poor exhaust.
Through the above test, we know that the misalignment of the valve phase and the ignition timing are too late may also cause this failure. Insufficient engine power may not be on the mechanical part, and in terms of signal control, although the fault light is not lit, the technical state of the sensor is not ruled out. A dedicated detector is installed on the detection interface to observe changes in each data stream.
To operate as an air conditioner, simply open the rear fan. After a period of use, it is proved that such improvement is completely feasible. So why didn't you find the solenoid valve bad at first?
In fact, since the car used air conditioners last summer, it has never used air conditioners during this summer. In addition, during this period, the car was overhauled and many air-conditioning pipes were removed. In this way, humid air will inevitably not enter. The pipe, which causes corrosion of the solenoid valve.
In view of the above three points, the difficulty of overhaul has been increased, and the author has misjudged the actual plugging point and a solenoid valve. It can be seen from this case that the maintenance must be analyzed in many aspects before making a judgment. From the reading of the instrument, the air conditioning system is not faulty, but when the engine speed is stabilized at about Zor/lnin, the pressure is changed, the high pressure is basically unchanged, and the low pressure is gradually decreasing until it drops to O. This means that the fault is on the evaporator expansion valve.
Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings.
From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types.
However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
