Pressure follow-up temperature control system special for wind power cooler

Abstract

The invention discloses a pressure follow-up temperature control system special for a wind power cooler. The pressure follow-up temperature control system comprises a pressure follow-up temperature control valve; the pressure follow-up temperature control valve comprises a valve body, a sliding cavity is formed in the valve body, a valve element capable of sliding along the sliding cavity in a reciprocating mode is arranged in the sliding cavity, the valve element is a hollow cylinder which is attached to the inner wall of the sliding cavity through the outer wall, an inlet and an outlet are formed in the valve body, an annular groove is formed in the circumferential direction of the sliding cavity, the annular groove communicates with the outlet, one end of the sliding cavity communicateswith the inlet, the other end of the sliding cavity is provided with a blocking piece, a valve cap is arranged in the valve element, the cap edge of the valve cap is connected with the inner wall ofthe valve element, the two ends of the spring abut against the valve cap and the blocking piece respectively, an overflowing hole is formed in the side wall of the valve element, and the overflow holecommunicates with an inlet through a cavity between the valve element and the valve cap. According to the pressure follow-up temperature control system, the pressure difference of the lubricating oilat different temperatures is controlled to be switched on and off, so that a switch function can be realized, an existing temperature control valve can be replaced, the problem that the fault rate ofthe temperature control valve is high is solved, and shutdown and maintenance of a fan are reduced.

Description

technical field [0001] The invention relates to the technical field of a wind power lubricating oil switch, in particular to a special pressure-following temperature control system for a wind power cooler. It is suitable for wind power lubrication systems with coolers installed. The pressure difference generated when the temperature of the lubricating oil changes can control the flow of the lubricating oil entering the cooler and the lubricating oil bypassing the cooler, so as to realize the control of the cooling back end lubricating oil temperature. Background technique [0002] The lubricating oil flow of the filter device of the wind power lubrication system is controlled by the temperature bulb expansion temperature control valve. When the temperature is lower than 45°C, the lubricating oil goes directly to the distributor without passing through the cooler; when the temperature rises to 45°C, the valve core Start to move, and gradually close the branch to the distribu...

AI Technical Summary

Problems solved by technology

[0002] The lubricating oil flow of the filter device of the wind power lubrication system is controlled by the temperature bulb expansion temperature control valve. When the temperature is lower than 45°C, the lubricating oil goes directly to the distributor without passing through the cooler; when the temperature rises to 45°C, the valve core Start to move, and gradually close the branch to the distributor. When the temperature rises to 60°C, the branch to the distributor is fully closed; due to the frequent action of the temperature control valve at low temperature, the damage rate of the temperature bulb expansion temperature control valve is too high, which is serious Affect the reliability of the equipment
