Manual powder tablet press is a powder press machine that compresses powder particles into round or other shapes. Manual powder tablet press is a device with a simple structure, consisting of a mechanical part and a piston working space. Pressing presses the powder placed in the mold into shape.
Manual powder tablet press can be used together with infrared chromatograph, X fluorescence analyzer, calcium iron analyzer and other instruments. Manual powder tablet press is often used in experiments and research on powder, superconductivity, building materials, new materials, green energy, etc. Compressed samples. As a kind of mechanical equipment, manual powder tablet press will inevitably have some faults during use. This article introduces the common fault causes and solutions of manual powder tablet press (this article takes Jinfulun’s manual powder tablet press as an example). There are the following points:
1. There is no pressure on the manual powder tablet press .
reason:
1) The oil inlet valve and oil outlet valve of the manual powder tablet press are not tight or there are foreign objects at the steel ball valve port
2) The powder tablet press has oil leakage
3) The hand wheel of the pressure relief valve of the manual powder tablet press is not tightened
4) The big piston rises more than 20mm
Solution:
A. After removing the foreign matter at the valve port, tap the steel ball a little to make it seal with the valve seat
B. Find the oil leakage of the manual powder tablet press to replace the seal or remove it
C. Tighten the pressure relief valve handwheel
D. Allow the large piston of the manual powder tablet press to reset before working
2. The manual powder tablet press has the phenomenon of dropping pressure or slowing down the pressure.
reason:
1) The pressure relief valve is not tight or closed tightly
2) There is an oil leak in the manual powder tablet press
3) The large piston of the manual powder tablet press has residual gas
Solution:
A. After removing the foreign matter at the valve port of the manual powder tablet press, tap the steel ball a little to make it seal well with the valve seat
B. Find the oil leak and replace the seal or remove it
C. Loosen the sealing screw on the top of the large piston of the manual powder tablet press, loosen the inner hexagonal screw, close the pressure relief valve, shake the pressure handle until the oil overflows from the top and reset one by one .
3. The mechanism of the manual powder tablet press is deformed
reason:
1) The pressure exceeds 35Mpa, the lead screw is bent or the structure is damaged
2) The manual powder tablet press makes the screws loose during frequent use
Solution:
A. The pressure is not allowed to exceed the range, replace the damaged parts
B. Tighten the column and nut of the manual powder tablet press .
The above are the common problems and solutions of manual powder tablet press.
