Description
Technical field
The present invention relates to a kind of displacement detector, a kind of variable cylinder of plunger pump displacement detector, belongs to 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, and piston rod 10 one end is provided with end cap 8, is provided with spring 9 between end cap 8 and cylinder body 11.Variable cylinder has two displacement stroke in left and right, and when depressing limited step in end cap 8 to cylinder body, the displacement that end cap 8 occurs is exactly right displacement stroke; When depressing piston rod 10 to time spacing, the displacement that piston rod 10 lower end occurs is exactly left dislocation stroke.Two, the left and right displacement stroke of variable cylinder determines the maximum output flow range of Variable plunger pump, therefore needs to detect two, the left and right displacement stroke of variable cylinder, to determine whether the displacement stroke of variable cylinder meets the requirement of ram pump delivery rate.
Tradition is after variable cylinder installs in ram pump to the detection of variable cylinder displacement stroke, and this pump maximum flow scope measured by upper test board, if disqualified upon inspection, dismounting ram pump again again, human and material resources, time waste are very large.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of variable cylinder of plunger pump displacement detector is provided, can conveniently carry out the stroke detection of variable cylinder left and right displacement, time saving and energy saving, improve work efficiency, reduce production cost.
According to technical scheme provided by the invention, variable cylinder of plunger pump displacement detector comprises positioning base, pressure head and displacement transducer, it is characterized in that: be provided with pressure head directly over positioning base, displacement transducer is positioned at directly over pressure head, and displacement transducer is electrically connected with displacement Displaying Meter.
Further, the second pressure surface is provided with in pressure head.
Further, pressure head lower end is provided with the first pressure surface.
Further, positioning base upper end is provided with positioning chamber.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, and displacement stroke is intuitively shown by displacement Displaying Meter, succinctly facilitates; Simple to operate, time saving and energy saving, improve work efficiency; Reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention 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 one end of positioning chamber 7 locator variable cylinder.
Be provided with pressure head 2 directly over positioning base 1, be provided with the second pressure surface 6 in pressure head 2, pressure head 2 lower end is provided with the first pressure surface 5.When detecting, by the second pressure surface 6, first pressure surface 5 clamping piston bar 10, end cap 8 simultaneously of pressure head 2.
The present invention also comprises displacement transducer 3, displacement transducer 3 is positioned at directly over pressure head 2, displacement transducer 3 is fixed on press front end, and displacement transducer 3 is electrically connected with displacement Displaying Meter 4, and the displacement that displacement transducer 3 detects is transferred in displacement Displaying Meter 4 and intuitively shows.
Principle of work of the present invention is: when detecting, be placed on by variable cylinder cylinder body 11 in positioning base 1, the press of Non-follow control installation position displacement sensor 3 down depresses end cap 8 until restraining position, right lateral journey now detected.Then be placed on end cap 8 by pressure head 2, the second pressure surface 6, first pressure surface 5 is clamping piston bar 10, end cap 8 simultaneously, and the press of Non-follow control installation position displacement sensor 3, toward pressing down pressure head 2, until reach restraining position, now detects left lateral journey.Structure of the present invention is simple, compact, reasonable, and displacement stroke is intuitively shown by displacement Displaying Meter, succinctly facilitates; Simple to operate, time saving and energy saving, improve work efficiency; Reduce production cost.
