Perfect further, measuring device sidepiece is provided with press device, press device comprises the second cylinder being arranged on support on support body and rack-mount portion, second cylinder piston rod is provided with press head, the base plate be fixed on support body is provided with below support body, this base plate is provided with one group of slide rail, tell base plate top and be provided with the worktable being slidably connected to slide rail outside, worktable one end is connected with and is placed between slide rail and drives the 3rd cylinder that worktable slides.Like this, by press head pressing piston place, prevent the piston assembly at piston place in running, easily produce leakage, be difficult to the working pressure and the flow that ensure compressor, affect the global stability of compressor.
Perfect further, the second cylinder is connected with the barometer for detecting cylinder internal air pressure.Like this, be convenient to judge whether cylinder internal air pressure is stablized, and whether is in normal operating air pressure by observing barometer.
Perfect further, support body bottom is provided with air valve.Like this; air valve can filter moisture entrained in pressurized gas; isolated steam and air is come by filter oil; then at water storage place, steam is hoarded; every day bleeds off ponding on time; itself carrying pressure display table and can be used for adjustable pressure, is also a kind of protective gear, flows into cause ponding in cylinder and block cylinder to avoid steam.
Perfect further, support body front end is provided with the circuit box that supply lines is placed, and circuit box is provided with the button be distributed on circuit box.Like this, in use, can each line group be put in order in circuit box, circuit can not so in a jumble, be also convenient to be connected with button, and make control knob realize controlling to each device.
The effect that the utility model is useful is: measured compressed machine initial point device of the present utility model not only accurately can record start distance, and in piston, the adjustment pad of some is added by the start distance recorded, it is made to reach best using effect, avoid due to long or too short the occurred fault of start distance, convenient and practical, time saving and energy saving, the popularization of value.
