Vacuum device:
When the vacuum level rises to the point where the water pump can discharge water, the mechanical float valve rises with the water surface, causing the induction float level probe to switch from normally closed to normally open. At the same time, the signal is transmitted to the electromagnetic transmission control system, causing the electromagnetic transmission control system to shut down and lose its magnetic force due to the power outage. That is, the belt driven rotary vane vacuum pump automatically stops running.
The self controlled belt driven rotary vane vacuum pump set is used in conjunction with it, which can achieve the function of automatic shutdown of the vacuum pump set when the vacuum degree rises to a high level, and automatic start-up of the vacuum pump set when the vacuum degree drops to a low level. It can be widely used in flood control, drainage, fire protection and other occasions. (Special note: If it is less than 1/3 of the oil testing port, 100 # high vacuum oil needs to be added)

Product Overview

The QZZSC strong self-priming double suction diesel engine mixed flow pump (with vacuum device) is a new energy-saving double suction self-priming pump product developed by our company according to market demand. It fills the historical gap of this type both internationally and domestically. It can start automatically without the need for water injection and can be automatically controlled (i.e. the vacuum pump set will automatically start when the vacuum degree drops to a low level, and automatically stop when the vacuum degree rises to a high level, without interfering with the operation of the main pump and playing an auxiliary role). It adopts a dry abrasion resistant structure design and can operate for 30 minutes. It can also suck shallow water and gas water mixtures. And obtained the national invention patent and utility model patent (patent number: ZL 2014 2 0197872.7)
This type of water pump completely solves the problems of high axial tension, long self-priming time, and low efficiency of single suction self-priming pumps. It has the advantages of high suction stroke, short self-priming time, high efficiency, significant energy-saving effect, stable operation, and long service life.
This type of water pump is suitable for various complex emergency rescue, firefighting and other occasions, and is not affected by factors such as power supply and usage site. It can be moved for operation and has high flexibility.
