Description

A mobile self-priming pump device

technical field

The invention belongs to the technical field of mechanical drainage and irrigation, in particular to a mobile self-priming water pump device.

Background technique

The pumping station project is an extremely important infrastructure in water conservancy construction. It is responsible for important tasks such as agricultural water lifting and irrigation, flood control and drainage, and domestic water supply for urban and rural residents. There are more than 500,000 fixed pumping stations in my country, which are distributed in cities, rural areas and river basins all over the country. While the fixed pump station plays a huge role, it also has many limitations, mainly in high engineering investment, poor flexibility and reliability. According to statistics, the civil construction part of fixed pump station investment often accounts for more than 50% of the total investment. In addition, a number of auxiliary equipment such as gates, cleaning machines, and cranes are required. Therefore, the equipment costs of the main water pump and supporting motors are fixed. The proportion of the construction cost of pumping stations is not large. In addition, fixed pumping stations have certain design standards. Under normal circumstances, these pumping stations can basically meet the requirements of irrigation and drainage. It exceeds the design standard of the pumping station, and cannot work normally because the water level is too high or too low, thus losing its function.

Since the 1990s, many domestic scientific research institutes and enterprises have successively carried out the research and development of mobile water pump systems. The mobile pump device developed by Liaoning Academy of Water Sciences is hoisted by a car crane to the appropriate position of the submersible electric pump. The device is equipped with a generator set, which will be started to pump water after the installation is completed. This kind of mobile pump is flexible in movement, but it takes a long time to prepare for installation, and the device needs to be equipped with a generator set, so the cost is relatively high. The mobile hydraulic submersible axial flow pump is jointly developed by Wuhan University and the Hubei Provincial Department of Water Resources. The traction machinery pulls the mobile pump to the work site, and relies on hydraulically driven water pumps to work. It has the advantages of flexible movement, convenient operation, and large pumping flow, but the structure is complex and the cost is high. The "Dragon Suction" vehicle-mounted mobile hydraulic water pump uses the car chassis as a platform to output the power of the car engine to the high-pressure oil pump through the full-power power output device to generate high-pressure oil to drive the hydraulic motor to drive the water pump impeller to rotate and drain water. The product moves fast and is flexible. Convenient, suitable for urban roads and places with better venues. However, it is difficult to be in place under complex road and site conditions such as mud and slopes, and the structure is complicated and the cost is high.
