Automatic waterway circulation device

Abstract

The invention discloses an automatic waterway circulation device for a thermal-humidity test chamber waterway system. The automatic waterway circulation device comprises a water pump (2) connected with a water storage tank (1). A one-way valve (3), a pressure controller (4), a hand valve (5), a water pressure gauge (6) and an electromagnetic valve (7) are sequentially arranged on a pipeline between the water storage tank (1) and a humidifying boiler (11), a mechanical water floating ball (8) and an electronic water floating ball (12) are installed on the upper portion inside the humidifying boiler (11), the electronic water floating ball (12) is connected with a relay of the water pump (2), a heating bar (9) is installed on the lower portion inside the humidifying boiler (11), and a steam outlet (10) is arranged on the top of the humidifying boiler (11). The reliability of the thermal-humidity test equipment waterway circulation system is improved, and defects in the prior art are overcome.

Description

technical field [0001] The invention relates to an automatic water circulation device, which is used in the water system of a damp heat test chamber and belongs to the field of mechanical equipment. Background technique [0002] Damp heat environment test is an important item of product environment and reliability test. Among them, the water circulation system is a key component of the humid heat environment test equipment, which is used to continuously provide demineralized water to the humidification boiler during the constant value damp heat test and alternating damp heat test. [0003] Existing wet heat environment test equipment usually adopts the water circuit circulation method with high and low water level difference to provide water source for the humidification boiler. The main feature of this water circulation system is to use the drop between the high-level water tank and the low-level water tank. During work, the softened water flows from the high-level water t...

AI Technical Summary

Problems solved by technology

Its shortcomings are: firstly, the water pump must work continuously to circulate the return water to the high-level water tank. The long-term full-load operation of the water pump not only consumes high energy, but also reduces the service life of the water pump; secondly, the working principle of the high-low water level difference not only requires The equipment must ensure that the water level has a sufficient height difference. Once the water level difference is insufficient, it is easy to cause poor water flow and affect the humidification function.
