Abstract

The utility model provides a pressure meter detecting device which solves the problems: the prior piston type pressure meter detecting device pressurizes an oil cylinder through a rotary piston, scales the pressure in the oil cylinder by a weight and detects the pressure meter; therefore, the piston type pressure meter detecting device not only is operated very inconveniently but also can not keep the pressure for a long time and continuously be pressurized depending on the experience of the user because of the leakage of pressure oil; hence the stability and accuracy of the pressure of the oil cylinder is greatly discounted. The main points of the utility model are that a motor, a speed reducer, a screw rod and the piston of the oil cylinder are connected with each other in turn; a pressure output end of the oil cylinder is connected with a pressure sensor; the pressure sensor and a computer form a feedback circuit of the device to control the speed and rotating direction of a motor. The utility model has the advantages that not only operation is simple and accuracy of the operation is high but also the pressure output value can be stably fixed on the setting value; furthermore, if the utility model is used for detecting the pressure meter and a pressure gauge, the accuracy of the pressure meter and pressure gauge can be improved.

Description

The pressure gauge calibrating installation
[technical field]
The utility model relates to and is used to examine and determine pressure gauge, manometric device.
[background technology]
Pressure gauge, tensimeter are used in the display pipes or the device of the gentle pressure of down-hole oil pressure.Therefore manometric error is the smaller the better.But pressure gauge in use for some time, particularly using than rugged environment is medium-term and long-term, error will occur, needs working pressure meter calibrating installation that pressure gauge is examined and determine and proofreaied and correct.The piston gage calibrating installation that uses is made up of oil cylinder, screw-type piston and counterweight etc. at present.Manually rotary-piston pressurizes to oil cylinder, demarcates pressure in the oil cylinder with counterweight, removes to examine and determine pressure gauge with the good pressure of this demarcation again.This shows that the piston gage calibrating installation not only operates very inconvenient, and,, the stability of pressure and accuracy are all had a greatly reduced quality by manually pressing according to experience is constantly continuous because the seepage of pressure oil makes its pressurize for a long time.
[summary of the invention]
The purpose of this utility model is to provide a kind of convenience, good stability, pressure gauge calibrating installation that degree of accuracy is high controlled.
The purpose of this utility model is achieved in that the piston of servomotor, reductor, leading screw and oil cylinder is connected successively, on the screw stationary work-table, pressure output end at oil cylinder connects pressure transducer, by the backfeed loop of pressure transducer and computer set cost device, controlling rotating speed of motor and turning to.The course of work is: by the computer settings pressure output value, servomotor starts, reductor, leading screw and piston rotation also feed or retreat, the oil cylinder output pressure, by pressure transducer detected pressures signal, feed back to the closed-loop system of forming by computing machine, make the pressure output value into setting value that becomes gradually, and pressure output value of the present utility model is stabilized on the setting value for a long time.Can remove to examine and determine pressure gauge, tensimeter etc. with it.
The utility model is compared with prior art, and is not only easy and simple to handle, the precision height, and its pressure output value is stabilized on the setting value for a long time, the utility model removes to examine and determine pressure gauge, tensimeter, can improve the precision of pressure gauge (table).
[description of drawings]
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
[embodiment]
Servomotor 1, reductor 3, leading screw 4 and the piston of oil cylinder 6 are connected successively, they are fixed on the base 7 jointly, guide rail 2 is arranged under this base, walking is on slideway, slideway is fixed on the worktable, on screw 5 stationary work-tables, connects pressure transducer 9 at the pressure output end of oil cylinder, form the backfeed loop of this device by pressure transducer and computing machine 10, controlling rotating speed of motor and turn to.The course of work is: by the computer settings pressure output value, servomotor starts, reductor, leading screw and piston rotate and feed or retreat along slideway, the oil cylinder output pressure by pressure transducer detected pressures signal, feeds back to the closed-loop system of being made up of computing machine, make the pressure output value into setting value that becomes gradually, and pressure output value of the present utility model is stabilized on the setting value for a long time, and can go to examine and determine pressure gauge, tensimeter etc. with it, can improve the precision of pressure gauge (table).
The 8th, fuel tank.
