Non-negative pressure water supply device used for heat energy equipment

Abstract

The invention provides a non-negative pressure water supply device used for heat energy equipment. The non-negative pressure water supply device comprises a base, on which a main water tank and an auxiliary water tank are arranged. The main water tank is connected with the auxiliary water tank by means of a water pipe. The middle of the water pipe is provided with a water pump. A pressure sensor is arranged in the main water tank, in which a water outlet is arranged. The auxiliary water tank is provided with a water inlet pipe. Due to the fact that the main water tank and the auxiliary water tank are connected by means of the water pipe, the main water tank is prevented from producing negative pressure such that water supply is not affected. No consideration is taken into poor states such as pressure shortage and overpressure and pressure of water tank can be detected by means of the pressure sensor such that problems of a conventional water supply device for heat energy equipment such as short service lifetime and the likelihood of blockage of water supply are solved. A fan is arranged above the water pump and used for cooling the water pump so that the water pump is prevented from being overheated, thereby avoiding short circuit. A liquid level detector is arranged in the main water tank in order to prevent water volume in the main water tank from being excessively large or small. A filtering device arranged on the water inlet pipe with the purpose of purifying water quality of water tanks and reducing production cost.

Description

technical field [0001] The invention relates to the field of heat energy equipment, in particular to a non-negative pressure water supply device for raising heat energy equipment. Background technique [0002] At present, the water supply system of thermal energy equipment usually needs to be equipped with water storage devices such as water tanks to supply water to thermal energy equipment. However, using the above-mentioned method as a water supply needs to generate negative pressure in the water tank, and then send water into the thermal energy equipment. The above-mentioned method Different working conditions such as undervoltage and overpressure in the water tank need to be considered, and corresponding protection devices need to be installed. The production cost is high, and the service life is not long. It is expensive to replace the protection device, and the negative pressure state in the water tank is easy to cause water supply to be blocked. . Therefore, it is pa...

Problems solved by technology

[0003] The purpose of the present invention is to provide a non-negative pressure water supply device for raising thermal energy equipment. Through the communication between the main water tank and the auxiliary water tank, it can prevent the negative pressure of the main water tank from affecting the water supply, and there is no need to consider bad conditions such as undervoltage and overpressure. And the pressure in the water tank is detected by the pressure sensor, which solves the problems of short service life of the water supply device of the thermal energy equipment and easy blockage of water supply
