Abstract
The utility model discloses the pressure medium electrical refrigeration plant of hydraulic press and comprises an electric freezer with an evaporator connected with a circulation loop which is connected with a circulation pump and an electric heater in series. The other end of the circulation loop is connected with the hydraulic pressure medium box of the hydraulic press. The utility model cools the hydraulic medium through the electrical freezer and the electric heater and can ensure to cool or heat the hydraulic medium to needed range under high or low temperature and the normal operation of the hydraulic press. Furthermore, the filter that is connected with the refrigeration loop can save previous filtering device that is installed in the hydraulic medium(oil) box, greatly simplify the structure and is easy to repair.
Description
Technical field
The utility model relates to a kind of hydraulic press hydraulic medium electricity refrigeration cooling unit, is used for the hydraulic medium that drives hydraulic press work is cooled or heats, so that its temperature remains in certain scope.
Background technique
Hydraulic press is the main tool in the forging and pressing processing, and it mainly is made up of the oil circuit that fluid cylinder, hydraulic medium case and oil hydraulic pump constitute, because piston moves in fluid cylinder and transformation can produce heat, makes that the hydraulic medium temperature rise in it is very big, need cool.Take the method cooling of water-cooled at present, its shortcoming is because the heat of water needs similar device radiations such as cooling tower, need take very big area, and complex structure is installed trouble; When ambient temperature too high (as summer) or low excessively (as northern winter), natural water-cooled just can not make oily temperature remain in the scope that needs, and influences the proper functioning of fluid cylinder in addition.
Summary of the invention
The purpose of this utility model just provides a kind of can be in ambient temperature too high and cross and to make when low fluid cylinder oil temperature remain on hydraulic press hydraulic medium electricity refrigeration cooling unit within the normal range (NR).
The technical solution of the utility model is: comprise electric refrigerator, be connected with circulation loop on its vaporizer, be in series with recycle pump and electric heater on this loop, the other end of this circulation loop is connected with the hydraulic medium case of hydraulic press.
On described circulation loop, also be in series with filter.
Also comprise control system, this system comprises controller and temperature transducer, and temperature transducer is connected with the input end of controller, and controller has different control ends to be connected with the control end of the power switch of electric refrigerator and electric heater respectively.
On described controller, control the port of hydraulic press hydraulic medium switch pump in addition.
Described electric refrigerator is made up of compressor, condenser, expansion valve, described vaporizer, the surge drum of circulation series connection successively, and the outlet of compressor connects the inlet of condenser, and the inlet of compressor connects the outlet of surge drum.
The utility model utilizes electric refrigerator and electric heater that hydraulic medium is lowered the temperature, and has guaranteed all the temperature of hydraulic medium to be cooled off or be heated in the scope of normal need under the environment of high low temperature, has guaranteed the proper functioning of hydraulic press.In addition, the filter that is connected on the cooling circuit also can save the filtrating equipment that was arranged on originally in hydraulic medium (oil) case, has simplified structure greatly, and is easy to maintenance.
