Description
Technical field
This utility model belongs to hydraulic cylinder manufacturing technology field, relates to a kind of hydraulic cylinder chiller, particularly relates to the chiller in the idle chamber of a kind of hydraulic cylinder.
Background technology
Hydraulic cylinder is executive component common in engineer applied.Because hydraulic cylinder mostly uses nitrile rubber to make sealing member, its operating temperature not can exceed that the working range of nitrile rubber.Otherwise, when hot operation, easily glutinousization is deadlocked, after sealing member hardness reduces, the phenomenon clamp-oning gap is more serious, and then accelerates its damage, destroys sealing effectiveness, and the sealing member of low temperature properties difference is when working at low temperatures, it is susceptible to compression set, also affects sealing effectiveness；Hardness is low, the sealing member of poor flexibility is easily clamp-oned seal clearance and caused destruction.
At present, in the case of having heat resistant requirements, the material generally changing sealing member meets duty requirements, but changes sealing member and can not improve the situation of cylinder body high temperature；A kind of hydraulic cylinder cooling system that Chinese Patent Application No. 201520548286.7 utility model patent provides, including hydraulic cylinder, in hydraulic cylinder, piston rod is the hollow structure of one end open, is provided with cooling tube in piston rod；Piston rod opening is fixed with the cooling tube termination sealed；Cooling tube one end is fixed on cooling tube termination, and the internal cavities of cooling tube connects with the internal cavities of piston rod；Cooling tube termination has the import of connection cooling tube internal cavities and the outlet connecting piston rod inner cavity, and the import and export of cooling tube termination is connected with cooling medium.Though piston rod playing in this invention cooling effect, but its effect being poor, additionally this inventive structure is complex, and owing to piston rod becomes hollow structure, therefore the bearing capacity of piston rod is limited by very large, and cooling structure is further improved.
Utility model content
The deficiency that this utility model in use occurs for above-mentioned existing hydraulic cylinder chiller makes improvements, the chiller in the idle chamber of a kind of hydraulic cylinder is proposed, optimize the structure of traditional cold radiator cooler, can realize cooling down being exchanged with each other of water, piston and sealing ring cooling effect can be improved, improve the operational efficiency of equipment.
The technical solution of the utility model is: the chiller in a kind of hydraulic cylinder is idle chamber, including the piston rod being arranged between left working cylinder and right working cylinder, arranges left piston on the piston rod and right piston and power cylinder；It is characterized in that: described power cylinder be arranged over cooling tube, the lower section of described power cylinder is provided with lower cooling tube, described upper cooling tube and lower cooling tube two are connected with described left working cylinder and right working cylinder respectively and communicate, described upper cooling tube is provided with water inlet pipe mouth, described lower cooling tube is provided with effluent pipe mouth, and the idle chamber, right side of described left working cylinder is connected with the idle chamber, left side of described right working cylinder by upper cooling tube, lower cooling tube.
Described upper cooling tube is connected with left and right working cylinder by welding manner with lower cooling tube.
Described water inlet pipe mouth is arranged on the top position of cooling tube.
Described effluent pipe mouth is arranged on the bottom position of lower cooling tube.
Described effluent pipe mouth is provided with sealing lid.
The beneficial effects of the utility model are: the chiller in the idle chamber of a kind of hydraulic cylinder that the utility model proposes, simple in construction, operation principle is clear, the mode welding cooling tube on left and right sides working cylinder is have employed in structure, cooling tube is divided into cooling tube and lower cooling tube, and upper cooling tube and lower cooling tube form cooling circuit each other, so idle chamber, both sides forms reciprocal cooling water, it is lubricated to piston packing and cools down, on while reciprocal, cooling tube ceaselessly accesses cooling water, it is provided with effluent pipe mouth bottom lower cooling tube, effluent pipe mouth is provided with sealing lid, can be so that discharging the impurity cooled down in water, improve cooling effect, improve the operational efficiency of equipment.
