Problems solved by technology

[0003] For existing condensate pumps, the concentricity of the pump shaft and the motor shaft must be guaranteed, and the deviation of the outer circle of the coupling must be within a certain range. Therefore, the foundation plane for installing the pump needs to be leveled with a spirit level. After the foundation cement solidifies, install the pump on the After laying the foundation, you need to use a level to correct the base, etc. The installation process is time-consuming and laborious
In order to reduce the liquid resistance during rotation, the current condensate pump usually designs the impeller to be relatively thin, even with edges. This structure is prone to low-pressure environment, cavitation, mechanical corrosion, and significantly reduced efficiency. , the cooling capacity of the condensate pump needs to be improved

Abstract

The invention discloses a combined condensate liquid pump. Connecting pipe combination parts are connected at the discharge end and can play a role in detecting the water flow, the water flow can be controlled more simply, conveniently and intuitively, the influence of a condensation pump device on the intensity of pressure can be reduced, the inner air pressure can be balanced, and the water flowspeed difference is reduced. Secondary condensation is carried out based on the principle of a heat exchanger, the condensation efficiency is improved, meanwhile the condensation process is smootherand steadier by the use of a base, and the device is protected.

Description

technical field [0001] The invention belongs to the field of chemical equipment, in particular to a composite condensate pump. Background technique [0002] Condensation pumps are vacuum pumps that use condensed gas on low-temperature surfaces. Condensation pumps are vacuum pumps with the lowest ultimate pressure and the largest pumping rate for clean vacuum. They are widely used in the research and production of semiconductors and integrated circuits, as well as molecular beam research, vacuum coating equipment, Vacuum surface analysis instruments, ion implanters and space simulation devices. Because of its outstanding advantages such as clean and pollution-free, high efficiency, high pumping speed, and high reliability, it is widely used in many fields such as scientific research laboratories and even industrial production, such as semiconductor material production, flat panel display production / testing equipment, solar energy Manufacturing, vacuum coating, thermal vacuum...
