Product features:
Compared with the domestic similar products, the mobile diesel engine fire pump has the advantages of simple structure, good self-priming performance, strong blowdown capacity, high efficiency and energy saving, and convenient use and maintenance. Each technical performance index is in the leading position in China and reaches the international advanced level. It has a wide application market and development prospect.
Product model: kdzy
Brief introduction: flow 50 ~ 3500m3 / h, lift 8-80m;
Structure: movable and fixed;
Main uses: municipal sewage project, flood control and drought relief project, farmland irrigation project, etc.
Kdzy four-wheel mobile pump truck series is a new product developed on the basis of repeated research on similar technologies at home and abroad. GB / t5657-1995 and gb1147.1. The pump set integrates self-priming and non clogging blowdown, adopts the diesel engine driven axial return and external mixing type, and through the unique design of pump body and impeller flow passage, it does not need to install bottom valve and irrigation and water diversion when in use. The pump unit can suck and discharge the liquid containing large particle solid and long fiber impurities, which can be widely used in municipal sewage discharge, flood prevention engineering, agricultural irrigation, etc. The pump set has the advantages of simple structure, good self-priming performance, strong blowdown capacity, high efficiency and energy saving, and convenient use and maintenance.
Model Description:
working principle:
Kdzy four-wheel mobile pump truck series mainly consists of diesel engine, coupling, pump head, impeller, rear cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water adding valve, inlet and discharge pipe, rain proof cabinet, four-wheel mobile trailer, etc.
Working principle of the pump: the pump body is provided with a liquid storage cavity, which is connected with the pump working cavity through the upper return hole and the lower circulation hole, forming the axial return external mixing system of the pump. After the pump stops working, the pump inner cavity has stored a certain volume of liquid. When the pump is started, the liquid storage in the pump is thrown upward under the action of the impeller, entrained with air, and the liquid passes through the network of the gas-liquid separation pipe The grid returns to the working chamber, and the gas is discharged out of the pump, so that a certain degree of vacuum is formed in the pump, and the self-priming effect is achieved.
