Description
Technical field
The utility model relates to a kind of displacement detector, and a kind of ram pump variable cylinder displacement detector belongs to the plunger pump technique field specifically.
Background technology
As shown in fig. 1, the variable cylinder of ram pump comprises cylinder body 11 and is arranged in the piston rod 10 of cylinder body 11 that piston rod 10 1 ends are provided with end cap 8, are provided with spring 9 between end cap 8 and the cylinder body 11.Two displacement stroke about variable cylinder has, when depressing end cap 8 in the cylinder body during limited step, the displacement that end cap 8 takes place is exactly right displacement stroke; When depressing piston rod 10 when spacing, the displacement that piston rod 10 lower ends take place is exactly the left dislocation stroke.Two displacement stroke have determined the maximum output flow range of Variable plunger pump about variable cylinder, therefore need detect two displacement stroke about variable cylinder, whether meet the requirement of ram pump delivery rate with the displacement stroke of determining variable cylinder.
Tradition is after variable cylinder installs in ram pump to the detection of variable cylinder displacement stroke, and last test board is measured this pump maximum flow scope, if disqualified upon inspection, dismounting ram pump again again, human and material resources, time waste are very big.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of ram pump variable cylinder displacement detector is provided, and can conveniently carry out the stroke detection of variable cylinder left and right displacement, and is time saving and energy saving, improved work efficiency, reduced production cost.
The technical scheme that provides according to the utility model, ram pump variable cylinder displacement detector comprises positioning base, pressure head and displacement transducer, it is characterized in that: be provided with pressure head directly over the positioning base, displacement transducer is positioned at directly over the pressure head, and displacement transducer is electrically connected with the displacement Displaying Meter.
Further, be provided with second pressure surface in the pressure head.
Further, the pressure head lower end is provided with first pressure surface.
Further, the positioning base upper end is provided with positioning chamber.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, and displacement stroke intuitively shows by the displacement Displaying Meter, and is succinct convenient; Simple to operate, time saving and energy saving, improved work efficiency; Reduced production cost.

Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-positioning base, 2-pressure head, 3-displacement transducer, 4-displacement Displaying Meter, 5-first pressure surface, 6-second pressure surface, 7-positioning chamber, 8-end cap, 9-spring, 10-piston rod, 11-cylinder body.
Embodiment
Embodiment during following the utility model is incited somebody to action by reference to the accompanying drawings is further described:
As shown in Figure 1, the utility model mainly comprises positioning base 1 and pressure head 2, and positioning base 1 upper end is provided with positioning chamber 7.When detecting, variable cylinder one end is arranged in positioning chamber 7, by an end of positioning chamber 7 locator variable cylinders.
Be provided with pressure head 2 directly over the positioning base 1, be provided with second pressure surface 6 in the pressure head 2, pressure head 2 lower ends are provided with first pressure surface 5.When detecting, by second pressure surface 6, first pressure surface, 5 while clamping piston bar 10, the end cap 8 of pressure head 2.
The utility model also comprises displacement transducer 3, displacement transducer 3 is positioned at directly over the pressure head 2, displacement transducer 3 is fixed on the press front end, and displacement transducer 3 is electrically connected with displacement Displaying Meter 4, and displacement transducer 3 detected displacements are transferred in the displacement Displaying Meter 4 and intuitively show.
Principle of work of the present utility model is: when detecting, variable cylinder cylinder body 11 is placed in the positioning base 1, manually controls the press of installation position displacement sensor 3 and down depress end cap 8 up to spacing position, detect the right lateral journey this moment.Then pressure head 2 is placed on the end cap 8, second pressure surface 6, first pressure surface 5 be clamping piston bar 10, end cap 8 simultaneously, manually controls the press of installation position displacement sensor 3 toward pressing down pressure head 2, up to reaching spacing position, detects the left lateral journey this moment.The utility model is simple in structure, compact, reasonable, and displacement stroke intuitively shows by the displacement Displaying Meter, and is succinct convenient; Simple to operate, time saving and energy saving, improved work efficiency; Reduced production cost.
