Problems solved by technology

[0009] 1. The above method requires the circulating oil pump and electric heater to be in working condition all the time, resulting in unnecessary waste of energy;
[0010] 2. Due to the harsh environment and large temperature difference, there are many connection points of working oil pipes on the equipment, which may easily cause working oil leakage

Embodiment Construction

[0029] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0030] The speed-regulating hydraulic coupling provided by the present invention changes the originally configured circulating oil pump 21 into an oil suction pump 30, cancels the second oil filter 16-2, the first check valve 17-1, and the second check valve 17- 2 and the second overflow valve 20-2, add a two-position two-way valve 29, one end of the two-position two-way valve 29 is connected to the oil suction pump 30 through a pipeline, and the other end is connected to the cooler 19 through a pipeline, forming a new adjustable speed fluid coupling, such as image 3 shown. The displacement of the oil suction pump 30 is smaller than that of the original circulating oil pump 21, and the oil flow direction is changed. The original circulating oil pump 21 sucks oil from the tank 18 and enters the cooler 19 through the second check ...

Abstract

The invention provides a speed regulating type hydraulic coupling which comprises a box containing hydraulic oil. A first oil filter and an electric heater are both immersed in the hydraulic oil, and a thermal resistor is arranged on the box. The first oil filter, a working oil pump, a cooler and a coupling rotating body are sequentially connected through working oil pipes, and an outlet of the coupling rotating body is connected to a hydraulic oil cavity of the box through the working oil pipe, so that a working oil system is formed. One end of an electromagnetic directional valve is connected with the pipe between the working oil pump and the cooler, the other end of the electromagnetic directional valve is connected with a suction port of an oil suction pump, and a discharging port of the oil suction pump is connected with the hydraulic oil cavity of the box. The working oil system is used for providing the hydraulic oil needed by normal work of the coupling; when the coupling needs to stop working, the working oil pump is stopped, the electromagnetic directional valve is powered on, and the oil suction pump is started to suck residual working oil in the working oil system back into the box. The speed regulating type hydraulic coupling is convenient to control, long in service life, low in energy consumption and simple in structure, the cost is reduced, and the use performance is improved.

Description

technical field [0001] The invention relates to a speed-regulating hydraulic coupler, in particular to a speed-regulating hydraulic coupler for outdoor use. Background technique [0002] The speed-regulating hydraulic coupling is a hydraulic transmission device that transmits power with liquid as the medium. It is installed between the electric motor and the working machine (such as fan, water pump, belt conveyor), and can be used without constant speed of the motor. Adjust the speed of the working machine step by step. [0003] The structure of the traditional variable speed hydraulic coupling is as follows: figure 1 As shown, it is mainly composed of an oil inlet and discharge cavity 1, a turbine shaft 2, a first bearing 3, a second bearing 4, an end cover 5, a rotating casing 6, an electric actuator 7, an electric heater 8, a back wheel 9, and a turbine 10 , pump wheel 11, third bearing 12, fourth bearing 13, working oil pump 14, pump wheel shaft 15, first oil filter 16...
