四柱液壓機在各首要加工職業中,在金屬加工職業的運用是十分之廣的，而通常的四柱液壓機走漏毛病出現會使四柱液壓機功率降低，并污染環境；內走漏的丟失轉為熱能，使體系油溫升高，影響液壓元件的功能和液壓體系的正常作業；外走漏還有可能引起火災。
因為走漏損害嚴峻，所以治漏作業是液壓設備運用中的重要作業，常常在以下幾方面采納辦法。
Because of serious leakage leakage damage, so the operation is an important operation of hydraulic equipment in use, often take measures in the following aspects.
①縫隙走漏時四柱液壓機走漏的首要方式，走漏量巨細與縫隙兩頭壓力差，液體粘度，縫隙的長度。寬度和高度等值有關，尤其是縫隙的高度對走漏的影響最為嚴峻，其走漏量與縫隙高度的三次方成正比，因此在規劃與制作液壓元件時，在結構和工藝答應的條件下，應盡量減小縫隙高度。
②因為四柱液壓機零件外表粗糙度使兩接合外表不可能各點都觸摸，因此在兩外表上下觸摸的微觀凹陷處，構成許多截面形狀多樣、巨細不能的孔隙，所以油液在壓力差的效果下，經過這些孔隙而走漏，為此關于液壓元件的各個蓋板、法蘭接頭、板式鏈接等接合外表，一定要保證合理的外表粗糙度；并且在安裝時，其緊固力度足夠大，保證螺釘擰緊擰牢，避免接合面發生傾斜。
Because the hydraulic machine parts surface roughness to two joint appearance may not all touch touch, so in two the appearance of the micro depressions, many section shape, size of pore fluid can not, so the pressure difference effect, through these pores and so on leakage, hydraulic components of each cover plate, flange joint, plate link joint appearance, must guarantee the reasonable surface roughness; and at the time of installation, the tightening force is large enough to ensure screw screw firmly, avoid joint surface tilt.
