This system has many merits such as integration design+ small ,olume

and easy for maintenance+ with the structural features as follows:

PF(Rfo

The chain tension system of wet type slag con,eyor is composed of oil

tan$ hydraulic unit;+ accumulator hung outside and electric control ca#inet-

*- r-c7o

Semi4closed and dustproof co,er structure is used for the oil tan$ to

pre,ent much dust and other su#stance from cone into the tan$-

@- X1Sco

&ir Dlter has #een set on the top of oil tan$ to ma$e the oil tan$ feed oil

upwards through the Dlter-- Pahc!"#$7$o

(e,el and temperature indicator has #een pro,ided in the face of oil tan$

to #e easy for watching the le,el and temperature in the oil tan$-

5- h%&c"o

If the oil le,el is lower than the min- scale of le,el and temperature

indicator or oil le,el can not #e seen;+ it means the le,el is low-

normal;

?- h%'c"o

If the oil le,el is higher than the ma'- scale of le,el and temperature

indicator or o,erAow of oil;+ it means the oil le,el is high- normal;

6- 70Ec"o

If the oil temperature is higher than 70E+ it means the temperature is

high- normal;

B- 1a(c)&2*+o

The Dlter at the inlet of oil pump has #een set on the oil tan$ and needs

to #e replaced regularly-
