Abstract
The utility model relates to a hydraulic oil cooling device of a truck mixer, which belongs to the field of a concrete conveyor. The utility model is a device which can guarantee oil temperature in the hydraulic transmission system of the truck mixer does not exceed the oil temperature which is allowed by a hydraulic pump. The hydraulic oil cooling device of a truck mixer is composed of an oil cooler (1), a fan (2), a direct current motor (3), a thermoswitch (4), a relay (5), an under frame (6), an air inlet cover (7), etc. The hot oil runs into the cooler through a port B, and the cooled oil flows out of a port C. When the oil temperature of the port B achieves the preset temperature, the thermoswitch makes the relay run, and then the fan is rotated; the cold air is sucked by the fan, so the hot oil passing from the cooler is cooled. The power supply of utility model adopts a primary storage battery of the truck, and the hydraulic oil cooling device of a truck mixer has the advantages of simple structure, energy saving, accurate temperature control and good cooling effect.
Description
The utility model relates to the concrete conveyer field, is a kind ofly to guarantee that the hydraulic oil temperature in the agitating lorry power hydraulic system is no more than the device that Hydraulic Pump allows the oil temperature, makes the agitating lorry can be in the high regional normal operation of ambient temperature.
Hydraulic Pump in the truck mixer power hydraulic system stipulates that the oily temperature of its hydraulic oil must not surpass 80 ℃, otherwise Volumetric efficiency is low excessively, hydraulic oil rotten, oil pump damages easily.The present not outfit hydraulic oil cooling device that has of the waggon that uses, what have has only cooling vessel and is not equipped with fan, and in China's south summer or the Middle East, the Far East and Central and South Asia area, waggon is difficult to normal operation.The waggon that has is furnished with cooling mechanism, and its fan adopts mechanical drive, complex structure, the startup of fan and stop bad control.
The purpose of this utility model be to design with simple in structure, temperature control accurately, the hydraulic oil cooling device of control comfort, saving electric power.
The utility model is made up of oil cooler (1), fan (2), DC motor (3), thermoresponsive switch (4), relay (5), underframe (6) and air intake cover (7) etc.The hydraulic oil of heat flows into cooling vessel by the B mouth, and cooled hydraulic oil is flowed out by the C mouth.Give when establishing temperature when B mouth oil temperature reaches, thermoresponsive switch (4) makes relay (5) action, connects the be open to the traffic circuit of storage battery of DC motor (3), fan (2) rotation and along D to sucking cold air, make the oily forced cooling that flows through cooling vessel.B mouth oil Wen Wei reaches and gives when establishing temperature, and the power supply of DC motor (3) is disconnected, and fan (2) does not rotate, thereby saves electric power.
Originally with regard to supporting storage battery arranged on the truck mixer chassis.The utility model adopts this storage battery to make power supply, and voltage is 24V or 12V, thereby simple in structure, temperature precise control, convenience, saving power supply, good cooling results.
Claims (2)
1, a kind of agitating lorry hydraulic oil cooling device, comprise underframe [6], hydraulic oil cooler [1], fan [2], feature of the present utility model is that thermoresponsive switch [4] is housed on hydraulic oil cooler, and DC motor [3] is by thermoresponsive switch [4], relay [5] control.
2, by the described cooling mechanism of claim 1, it is characterized in that DC motor (3) by the battery traction on the waggon chassis, voltage is 24V or 12V.
