How to adjust a self-priming pump that frequently starts and stops

How to adjust a self-priming pump that frequently starts and stops

Self-priming pump, also known as miniature water pump, is an industrial water conveying equipment that uses the principle of negative pressure to achieve waterless start-up. It draws water by extracting air through the vacuum effect of the pump body, and is mainly used in agricultural irrigation, industrial cleaning and other scenarios. It has the advantages of self-priming, strong discharge capacity, and simple operation. However, in actual use, there are sometimes frequent problems of starting and stopping, which not only affects the normal operation of the equipment, but may also damage the equipment. This article will introduce several effective adjustment methods for this problem.

How to install the oil pump seal

How to install the oil pump seal

As a critical component in the fuel system, the oil pump's sealing performance directly affects the normal operation of the engine. The sealing ring, as an important component in the oil pump, plays a crucial role in preventing fuel leakage and maintaining system pressure. Once the sealing ring ages or is damaged, it may lead to fuel leakage, which in turn affects engine performance and fuel economy. Therefore, the correct installation of the oil pump sealing ring is particularly important. This article will detail the installation steps and precautions for the oil pump sealing ring to help you complete this important maintenance work.

Reasons why self-balancing pump seals are not wear-resistant

Reasons why self-balancing pump seals are not wear-resistant

The wear resistance of the self-balancing pump seal directly affects the sealing effect and service life of the pump. Its lack of wear resistance is the result of multiple factors. It is necessary to comprehensively investigate the specific working conditions (medium, temperature, pressure), installation accuracy, material selection, and operation and maintenance to solve the problem in a targeted manner.

How do self-balancing pumps in the salt chemical industry adapt to the long-term operation of media with high solids content?

How do self-balancing pumps in the salt chemical industry adapt to the long-term operation of media with high solids content?

In the salt chemical industry, the problems of wear, blockage, and corrosion of pumps caused by high solid content media are particularly prominent. Self-balancing multistage centrifugal pumps eliminate the traditional balancing disc device of multistage pumps and achieve axial force self-balancing through symmetrical impeller arrangement, making them structurally more suitable for harsh working conditions. The core logic for their long-term operation in adapting to high solid content media is: "Wear resistance, anti-clogging, corrosion resistance, and vibration reduction."
