Small make up teach you how to solve the pressure gauge pointer is not zero

Pressure gauge pointer is not zero is a common quality problems, below small make up to you to solve common causes and repair methods. Pressure gauge pointer is not zero, a common cause and repair method is as follows: 1, when the pointer is loose, hammer on pointer 2, when the balance spring torque is too small, would reverse rotation center axis, increasing the balance spring friction torque 3, transmission gear, adjust transmission gear tooth clearance 4, if the hair loss, just to pack good hair loose 5, if the dial is not binding, will adjust the dial fixed screw 6, if the pointer on the dial or glass table, just correct the pointer shaft, then place heavy needle gauge refers to elastic element as the sensitive element, measure and instructions above environmental pressure meter, application is very common, it almost throughout all of the industrial process and research fields. In the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance shop, etc can be seen everywhere. Especially in the process of industrial process control and technology measure, due to the flexibility of mechanical pressure gauge sensor has high mechanical strength and production is convenient wait for a characteristic, make the mechanical pressure gauge is widely used. Pressure gauge is a sensitive element (by table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure.
