The main purpose of diesel engine pumps
The diesel fire pump is mainly divided into two types. The other base of the ZW self-priming sewage pump diesel pump unit is based on the new strong self-priming pump, which adds a vacuum auxiliary device for the diesel pump unit system.


In addition, the diesel engine automatic stop vacuum pump is an auxiliary system. When it is detected that water is automatically stopped by the vacuum pump vacuum pump and the clutch, the price of the diesel pump is relatively high, and the performance of the two vacuum-assisted diesel engines is self-priming. Diesel pumps can suck and discharge large particles of solid and long-fiber impurity liquids, especially the new vacuum-assisted diesel water pump impellers, which can make the impeller structure of self-priming pumps with particle capacity more prominent.
 
Diesel pumps can be widely used in urban sewage and waterlogging projects, agricultural irrigation and other diesel engine pumps. They have simple structure, strong, good self-priming performance, strong drainage capacity, high energy efficiency, convenient use and maintenance, integrated or outdoor mobile design, etc. Self-priming pump series products are the first in China. In the diesel self-priming pump series, the domestic initiative is an ideal treatment method for sewage pumps containing solid particles. The non-clogging impeller design can reach a maximum size of 76mm solid particles.
 
You only need to install the diesel pump in the sewage pit, and the suction pipe can work below the liquid level. It can effectively replace the submersible sewage pump and liquid pump. Without any lifting tools, the water pump can be installed, maintained and routinely used on the ground maintain.


Suddenly stopped in the operation of the pump, many people do not know the cause of the failure. When encountering this problem, the first reaction is that there is a problem with the quality of the pump. In fact, there are many reasons for this problem. improper. How to determine the cause and solution of the problem? Let us teach you the following.

1. Centrifugal pump impeller or pipeline is seriously blocked. In this case, after a period of use, the impeller of the centrifugal pump is blocked by foreign particles in the liquid. Before choosing a pump, make sure your liquid contains particulate impurities.


2. When the suction pump is selected, the suction volume of the pump is too high, which causes the pump to be idle for a long time. Therefore, when selecting a self-priming pump, you must determine the pump's self-priming height to meet your needs.


3. The packing box is not tightly packed or sealed, causing air to leak into the pump casing. For example, if a single-screw pump does not replace consumables for a long period of time, you need to check whether the consumables are worn, including mechanical seals or packing.


4. The pump creates air or leaking pipes at the inlet. Leaks from the pump can also cause the pump to pump out liquid, especially self-priming pumps. If leaking liquid is not easily absorbed, the inlet piping must be sealed.


5. The depth of the foot valve or the inlet pipe is not enough. This situation is similar to Article 5, that is, the inlet water of the pump is not enough, or the air pump cannot absorb it, and the motor is overloaded to cause a stop.


6. Insufficient water in pumping heat or liquid. Make sure that the pump inlet is sufficient and that there is too little liquid. The pump can easily be overloaded and cause the pump to stop.


7, pump body damage seal, this is more common, because many pumps use rubber seals. If the smoke is high temperature or corrosive liquids, such as centrifugal pumps, IHF fluorine-lined use for a long time will cause corrosion or gasket seal aging, so that Pump body leaks and leaks.


All of these can cause the pump to shut down for no reason, affecting work efficiency. Therefore, in our daily work, we mainly check the existing static pressure head to see whether the inlet of the pipeline is reasonable, to see if there is an obstacle between the equipment, and to check whether there are air bubbles in the suction line, or to seal the packaging. Check and replace in time, regularly lubricate, increase the tip, communicate with the factory, solve the problem in time, use the force of the baffle to eliminate eddy current, strictly control the depth of burial according to the instructions, and the gasket cannot be ignored at the same time. Variety.
