Don't pressure gauge pointer to zero can repair

The working principle of 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. Encounter pressure gauge in the process of transportation, vibration, due to the inadvertent, packing cases suffered serious break, causing pressure gauge pointer is not zero. Don't pressure gauge pointer to zero can repair? Of course I can. Introduces for you below instrument to gauge pressure is not zero in common cause and repair method is as follows: a loose, Pointers: maintenance methods: hammer on pointer (2) balance spring torque is too small; Maintenance methods: reverse rotation center axis, increasing the balance spring three, transmission gear friction torque; Maintenance methods: adjust the four driving gear tooth clearance, fall off balance spring; Maintenance methods: five, dial back pack good balance spring loose not tight; Maintenance methods: solid screw adjustment dial 6, pointer on the dial and glass table; Maintenance methods: correct the pointer shaft, again place heavy pointer according to the above introduction, we encounter pressure gauge pointer is not zero can repair itself, can greatly save the cost.
