Characteristics and application of diesel engine self-primin

Article provenance：Hai Rui ZhonglianPopularity：Publication time：2020-03-24 09:00

The self-priming pump of diesel engine is mainly divided into two types: one is the self-priming pump set of diesel engine based on ZW Self-priming sewage pump, the other is the pump set system of diesel engine based on new strong self-priming pump and adding vacuum auxiliary device. The difference between the two types of diesel Self-priming pumps is that the purchase cost of ordinary diesel self-priming pump is low, the self-priming height is only 4-5m, and the maximum flow is only 800m3, while the new diesel self-priming pump has the greatest advantage of vacuum assisted self-priming height. The valve rod can reach 8-9m, the outlet time is fast, the flow range is wide, and the maximum flow can reach 2600m3 / h.

There are two kinds of vacuum auxiliary devices for diesel self-priming pump vacuum auxiliary device, which can be used by users to select the vacuum pump system based on the power of diesel engine shaft. Pulley driven vacuum pump and diesel engine self-priming pump work together, the whole system has been in the suction vacuum state. The performance of self-priming pump is stable. Vacuum assisted diesel engine is called non stop self-priming pump.

Another diesel engine self-priming pump is a vacuum assisted system, which can stop automatically. When the vacuum pump pumps water, the vacuum pump automatically stops through the clutch. The price of diesel self-priming pump is relatively high. Two vacuum assisted diesel engines are self-priming. The suction pump has the same self-priming performance.

Diesel engine self-priming pump can suck and discharge liquid containing large solid particles and long fiber impurities. In particular, the impeller of the new diesel vacuum self-priming pump can be made into an open impeller structure, and the ability of self-priming pump to pass particles is more significant.

Diesel self-priming pump can be widely used in municipal sewage, flood control engineering, agricultural irrigation, etc. The self-priming pump of diesel engine has the advantages of simple structure, good self absorption performance, strong blowdown force, high energy saving efficiency, convenient operation and maintenance, and overall or movable design.

Diesel self-priming pump consists of diesel engine, water pump, coupling, cooling fan, cooling water tank, steel structure base (including 80-120L bottom tank according to user requirements), battery and connecting line, exhaust muffler, control panel. The standard design is pump unit, bottom tank, control panel and battery pack.

Diesel engine self-priming pump can be designed as combined outdoor pump set, bottom oil tank, control panel, battery set and outdoor rain proof tank according to customer requirements.

Diesel engine self-priming pump is the principle of diesel engine as power supply pump. At present, it is widely used in fire protection, environmental protection, chemical industry, industrial emergency, agricultural irrigation, construction and other fields.
