Flood control emergency mobile hand lift diesel fire pump

In civil buildings, there are many types and quantities of electrical equipment, not only fire fighting equipment such as fire pumps and sprinkler pumps. In order to meet the reliability of power consumption of these devices, when the municipal power grid cannot provide two independent power sources, the method of using diesel generator sets as a backup power source in the design is widely used.

The so-called auxiliary impeller hydrodynamic seal of diesel engine fire pump refers to the installation of an open impeller in the opposite direction coaxially near the back of the impeller rear cover plate of the diesel engine fire pump. When the diesel engine fire pump is working, the auxiliary impeller rotates with the main shaft of the pump, and the liquid in the auxiliary impeller also rotates together, and the rotating liquid will generate an outward centrifugal force. pressure at the mechanical seal. On the other hand, the solid particles in the medium are prevented from entering the friction pair of the diesel engine fire pump seal, and the wear of the mechanical seal grinding block is reduced. In addition to the sealing function, the auxiliary impeller of the diesel engine fire pump can also reduce the axial force.

    The mobile pump truck mainly relies on the rotation of the impeller to create a vacuum zone, and the inhaled liquid relies on the centrifugal force developed by the impeller to generate a large amount of pressure and a very fast speed. Stainless steel and other materials are available for selection. Private customization is also possible, and customers can design reasonably if they need it. The mobile pump truck inputs a part of the energy into the diversion shell and steps into the impeller of the next level. The pressure generated increases in proportion to the number of pumps, and then passes through the water pipe pump base to reach the pipeline program on the construction ground. Based on scientific design thinking and technical improvement in long-term practical operation, the mobile pump truck will enhance its image as a smart and practical new pump truck in terms of the entire water displacement treatment.

    The design of the mobile pump truck can highlight the integration of cutting-edge science and the combined control of various systems, reducing the weight of the entire mobile pump truck, eliminating the heavy and rough image of the previous water pump, and reducing the input of operators. , It is also convenient for multiple transportation, long-distance transmission is no longer a problem and ensures timeliness, but its own emission performance will increase without decreasing, and the displacement that can be handled has increased, while the pump truck itself has reduced the size of the traditional pump truck. Ten times as much in weight. The construction personnel can easily make up for the more tragic losses caused by the mobile pump truck before the floods rage.

    The Emergency Drainage Mobile Pump Truck adopts an integrated design, is durable, and is equipped with a vacuum auxiliary system, which has the characteristics of fast water absorption and high efficiency. It is suitable for flood control and drainage, and is equipped with a mobile diesel engine self-priming pump, a trailer-type emergency drainage pump truck, a 4-wheel mobile pump truck, and a combination of diesel engine and self-priming pump, with manual and automatic control settings. The diesel engine self-priming pump integrates self-priming and non-clogging sewage discharge, adopting an axial backflow external mixing type. Through the unique design of the pump body and impeller flow channel, it does not need to install a bottom valve and a tank like a general self-priming clean water pump. It can be used for water diversion, and it can absorb and discharge liquid containing large solid particles and long fiber impurities. It can be used for municipal sewage discharge, flood control, drought relief, river pond breeding, light industry, paper making, textile, food, chemical industry, electrical industry, fiber, slurry and mixed suspension, etc. Compared with domestic similar products, diesel engine self-priming pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, energy saving, convenient use and maintenance, etc. The mobile pump truck has good mobility and simple operation, and has application market and development prospects.
