Product Description

Product Parameters

 

Pillar transportation and storage
(1) When the pillar is transported, the pillar should be reduced to the minimum height;
(2) Use a special hydraulic prop transport vehicle, and it must be handled with care during installation and disassembly, and it is strictly forbidden to drop it;
(3) Pillars should be stored in a dry room not lower than 0ºC;
(4) For pillars that are not in use for a short period of time, the water (or emulsion) in the pillar cavity should be cleaned, the surface of the cylinder body should be
washed and dried, and the liquid inlet of the three-way valve should be blocked to prevent stolen goods from entering;
(5) The pillars stored in the groove on the working face should be erected and neatly arranged;
(6) The number of spare pillars in the well generally does not exceed 5% of the working face usage.
Precautions for the use of pillars
(1) When the pillar is in use, do not use it at the highest height;
(2) Pillars should generally be used in conjunction with metal hinged top beams;
(3) For new pillars and pillars used for the first time after restoration, the air in the inner cavity of the pillars shall be discharged;
(4) When supporting the pillar, flush the liquid injection valve body of the one-way valve with a liquid injection gun to avoid coal dust pollution and affect the
performance of the valve;
(5) When supporting pillars, the direction of the liquid injection valve body of the three-way valve is toward the downward groove direction of the working surface;
(6) Special drifting jacks should be used for migration, and the waist of the pillar should not be used as the fulcrum of migration;
(7) Hard objects such as hammers and picks are not allowed to knock the cylinder body and three-purpose valve;
(8) The retracted pillars should be lowered to the lowest height, and immediately placed on the side against the old lint. It is forbidden to throw them on the bottom
plate;
(9) Liquid injection guns are not allowed to be placed randomly. After injection, they should be hung on the handle of the second row of pillars;
(10) When crushing, it is strictly forbidden to use blasting or deadlift with a post-returning machine. Undercover methods should be used to loosen the pillars and then pull them out.
 

Solution	Category	Malfunction	cause of issue
Check the pumping station; Open the shut-off valve; Clean the injection valve nozzle; Clean the filter	Lifting column failure	The movable post does not protrude from the cylinder body or protrudes very slowly when supporting	No pressure or low pressure in the pumping station; The shut-off valve is closed; The injection valve nozzle is blocked by dirt; Clogged pipeline filter
Re-hang the return spring orreplace with a new spring; Replace damaged parts	Back column failure	Slow or no drop of the moving column	The return spring is dropped or damaged; The cylinder has a partial depression; Damage to the surface of the live post
Replace the Y-ring, replace the cylinder; Replace the O-ring; Replace with new valve or clean one-way valve, unload valve pad	Seal failure	1. Liquid leakage from the handle; 2. Liquid leakage from the base; 3. Liquid leakage from the φ42 hole on the column head; 4. Leakage from check valve or unloading port	The Y-ring is damaged, the oil cylinder is deformed or the coating falls off; The base φ100×3.1 O-ring is damaged; φ42×3.5 O-ring is damaged; Check valve, unloading valve is damaged
