High pressure hydraulic oil calibration hand pump pressure tester calibration machine

High pressure hydraulic oil hand pump calibrattion is a portable pressure pump.For field installation of instrument calibration in the industrial process and control of indoor use all kinds of pressure gauges.Can also provide pressure source correction table for pressure measuring instrument manufacturer.All kinds of pressure transmitter within every 60 M pa,Pressure sensor and all kinds of pressure gauges Check all available hand pressure pump.  

·Portable, light weight,,Suppression of light.

·Easy to use Structural design pressure fine-tuning hand,Rotate the fine-tuning hand can easily change the output pressure.Also comes with a high-pressure hose connection is timing ,Meter connector connect pressure gauge .
·Hand pressure pump is the handle, the piston rod. Through gas, pump cover, put the oil hand, fine-tuning hand, form joint, rotation.

Manual of high pressure hydraulic oil hand pump calibration:

1.Turn on the oil hole screw and pour diisooctyl sebacate or transformer oil into the cup to 1/2 of the cup height.
2. Screw on the oil hole screw, connect the pressure gauge calibrated with output connector according to thread and output connector, or connect via high pressure hose. 
3. Pressure fine-tuning rotates counterclockwise by 10mm (Max 15mm);
4. Hold the pressurized handle repeatedly,When there is no bubble on the oil surface, close the relief valve counterclockwise.
5.Continue holding pressurized handle ,until the pressure up to the pressure required.(in the case of the pressure is higher and laborious,can be with the aid of pressure fine-tuning, fine-tuning pressure range is about 10mpa)
