Description
Technical field
The utility model relates to a kind of detection device, specifically mobile hydraulic oil cylinder detection device.
Background technique
Because hydraulic jack is an actuator in the hydraulic system, it all is made up of a plurality of oil cylinders in each hydraulic system as people's hand and pin.And the reparation of oil cylinder after will changing once sealing and wearing and tearing in each year basically reparation and carry out special detection, thereby guarantee normal the use.
Summary of the invention
The utility model is intended to overcome the defective of existing technology, and a kind of mobile hydraulic oil cylinder detection device is provided, and adopts Air cooler successfully to solve test site and does not have the water source and hydraulic oil can't be cooled off, and guarantees that hydraulic pressure detects normal operation.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of mobile hydraulic oil cylinder detection device, it comprises fuel tank, duplex pump, motor, two solenoid directional control valves, relay and relief valves; The import of duplex pump connects the outlet of fuel tank; The duplex delivery side of pump connects the import of two solenoid directional control valves respectively; Be connected with relief valve through relay after the outlet parallel connection of two solenoid directional control valves; Motor is connected with duplex pump, it is characterized in that: it also comprises Air cooler, and this Air cooler is connected between the import of outlet and fuel tank of two solenoid directional control valves.
The beneficial effect of the utility model is: the one, cut down the consumption of energy, and raise the efficiency; The 2nd, adapt to environmental requirement, prevent gas leak of the oil leakage, reduce noise; The 3rd, improve level of pollution control; The 4th, realize electronization (mechanical electronic hydraulic gas integral); The 5th, fluid dynamic element, unit and main frame combine together.Adopting Air cooler successfully to solve test site does not have the water source and hydraulic oil can't be cooled off, and guarantees that hydraulic pressure detects normal operation.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1: a kind of mobile hydraulic oil cylinder detection device, it comprises fuel tank 1, duplex pump 3, motor 2, two solenoid directional control valves 4, relay 5 and relief valves 6; The import of duplex pump 3 connects the outlet of fuel tank 1; The outlet of duplex pump 3 connects the import of two solenoid directional control valves 4 respectively; Be connected with relief valve 6 through relay 5 after the outlet parallel connection of two solenoid directional control valves 4; Motor 2 is connected with duplex pump 3, it is characterized in that: it also comprises Air cooler 7, and this Air cooler 7 is connected between the import of outlet and fuel tank 1 of two solenoid directional control valves 4.
The utility model adopts duplex pump 3, realizes low pressure and mass flow, and high-pressure low-flow reduces energy loss, solves the too fast source of hydraulic fluid temperature rising.Adopting Air cooler 7 successfully to solve test site does not have the water source and hydraulic oil can't be cooled off, and guarantees that hydraulic pressure detects normal operation.
