The solution that the pressure calibrator pressure can't get up

The pressure calibrator cleans the entire system with gasoline before use, adds a small amount of gasoline from the oil cup, and then rotates the handle back and forth to achieve the purpose of cleaning the entire system. After cleaning, turn the handle to close, pour out the gasoline, and use it until it is completely dry. The purpose of this is to prevent the blockage of the body caused by impurities entering the system during transportation. Do you know these? The following is a small series led by everyone to learn the solution to the pressure calibrator pressure can not be reached.

The pressure calibrator reflects the pressure, and the possible problems and solutions are as follows:

1. It may be that the "O" type ring in the quick connector of the pressure hose equipped with the pressure output is lost, so that the output does not seal the pressure, and the sealing ring should be placed on it.

Second, it may be that the checklist is not connected. Method: Use M10*1 plug to directly block the pressure output port, and then press to check the seal itself. If the leak indicates that the calibrator leaks, if there is no leak Can add pressure, indicating that the checklist is not connected.

Third, if the instrument is with positive pressure, but also with negative pressure, it may be that the positive and negative pressure switch is not switched into place, the switch is fully pulled out when verifying the positive pressure, and the switch should be placed in place when verifying the negative pressure.

Fourth, it may be that the low pressure is still good when the pressure is applied. When the high pressure is pressurized, the hand pressure pump will not push in and out, and the resistance is large. When the pressure is applied, the hand pressure pump must be pushed into place, and the pressure can be entered from the one-way valve. It should be felt that there is a feeling that the piston collides with the front, which means that the pressure pump is pushed into place.

5. The valve may not be locked, the pressure calibrator cannot hold the pressure, and the valve should be locked clockwise.

The detailed analysis of this article is over here, I hope that the careful editing of Xiaobian can bring convenience to all users. The pressure calibrator not only solves the calibration of the standard pressure, but also better meets the comprehensive testing needs of the field. Nowadays, there are many manufacturers who have miniaturized and intelligentized the whole instrument in order to facilitate the customer. This makes the pressure calibrator have functions such as multi-range and recording. The pressure calibrator is divided into two types: modular and integrated. The pressure calibrator represents the future direction of the product because of its portability. The pressure calibrator is a new type of test instrument, which not only solves the calibration of the standard pressure, but also better meets the comprehensive test needs of the field.
