Do you know the reason why the diesel water pump often fails to pump water? What is the cause of these failures? What are the differences? Here, we wil make the clear explanation for the reasons of not pumping water. There are four reasons for pumps not pumping water. Firstly, the impeller ratation is unbalanced, […]

The basic structure of diesel water pump is composed of impeller, pump body, pump shaft, bearing, sealing ring and stuffing box. The impeller is the core part of the high-lift self-priming pump. It has a high speed and a large output, and the blades on the wheel play a major role. The impeller must pass […]

The correct maintenance of the diesel engine water pump, especially preventive maintenance, is the easiest and most economical maintenance, so it is the key to extending the service life and reducing the cost of use. Routine maintenance can be carried out according to the following steps to check the amount of fuel in the fuel […]

In order to ensure that users can safely operate the diesel water pump unit, please read the instruction manual attached to the water pump carefully. But please pay special attention to the following points of use to avoid accidental casualties and equipment damage: Precautions for muffler: 1) Since the gas discharged from diesel engines contains […]

Diesel trash pumps also have their own structural characteristics, and their lifts are not high. Because there are more debris in the diesel trash pump, the clearance of the impeller is larger than that of the diesel clean water pump. Therefore, the diesel trash pump is prone to failure. Similar to a general centrifugal pump, […]

Because the water pump is driven by the engine, the speed of the water pump is directly related to the speed of the engine. (1) Impact on pump lift Commonly used motors for water pumps are 2-pole, 4-pole, 6-pole, geared motors and speed-regulating motors. The same type of water pump is maintained at a certain […]

A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspension emulsions and liquid metals. […]

When preparing to start the diesel engine water pump for the first time, it is necessary to check the installation of all equipment and prepare for the start in the following order: 1. Inject engine oil into the suspension of the diesel engine and water pump from the fuel filling port, and check whether the […]

If the diesel water pump is not operated in the correct way during use, various faults may occur. At this time, you must conduct a comprehensive inspection on it first. Different problem handling methods are also different. Here are some solutions to common failures in water pump maintenance. Cannot startFirst, check the power supply: whether […]

The diesel cast iron pump is the inherent characteristic of the pump itself, it has nothing to do with the external use. However, once the pump is arranged to work in a certain pipeline system, its actual working situation is not only related to the characteristics of the centrifugal pump itself, but also depends on […]

Choosing a diesel clean water pump is actually choosing the right head and flow.The so-called head refers to the required head, not the lifting height. It is particularly important to know this point when choosing a diesel clean water pump. The lift of the clean water pump is approximately 1.15 to 1.20 times the lifting […]

Sewage pumps and submersible pumps are common equipment in the industry. There is a difference between the two. So what is the difference between sewage pumps and submersible pumps?Both sewage pumps and submersible pumps need to be submerged in water. To a certain extent, sewage pumps are a kind of submersible pumps, but there are […]

The diesel high-pressure pump is a product that allows a piston to move back and forth through a seal. The diesel high-pressure pump mainly relies on the reciprocating movement of the piston, which makes the working volume of the pump body change periodically to realize the liquid suction and discharge. Its main function is to […]

Diesel engines are compression ignition, and the work of diesel engines is composed of four processes of intake air to form a working cycle. A diesel engine that takes four processes to complete one working cycle is called a four-stroke diesel engine. The working principle of “intake stroke” is now explained in detail with reference […]

The speed of the water pump is different, the specific speed of the high-pressure pump is relatively small; the head is different, the head of the high-pressure pump is higher at the same flow rate; the material of the pump body and the shaft is different; the volume of the high-pressure pump is larger.The high-pressure […]
