- What aspects must be paid attention to choosing the fire pump?
- 2021.03.31
- 1. The material of fire pumps: the fire pumps sold on the market look similar in appearance, and some products are even made exactly the same, but although the two are exactly the same, they are different in quality. One point can be seen in the later use. A good fire pump has the characteristics of good starting characteristics, strong overload capacity, compact structure, convenient maintenance, simple use, and high degree of automation.

- The serious impact of the pump cavitation
- 2021.03.29
- The serious impact of the pump cavitation When cavitation develops to a certain degree, it will affect the performance of the pump and hinder its normal operation. Mainly manifested in the following aspects:
-
- What causes the Low speed of fire pump
- 2021.03.26
- Low speed of fire pump (1) Human factors. Due to the damage of the original electric motor, a considerable part of the users randomly equip the fire pump with another electric motor to drive it. As a result, the flow rate is low, the head is low, or even cannot pump water. (2) The transmission belt is worn. There are many large-scale fire pumps that use belt transmission.

- The reasons for the temperature rise of fire pump bearings | ZJBetter
- 2021.03.25
- The primary reasons for the temperature rise of fire pump bearings are: (1) The tortuosity or absence of the pump shaft will cause the pump to oscillate and cause heating or wear of the bearing. Due to the axial thrust of (2) (for example, when the balance plate and the balance ring in the water pump are severely damaged), the axial load of the bearing increases, causing the bearing to generate heat and even damage.

- What is the cause of the water leak of fire pump? | ZJBetter
- 2021.03.22
- What is the cause of the water leak of fire pump? How to solve it? 1. The fire pump sealing ring loses its elasticity due to long-term use. At this time, the sealing ring can be taken out, and cut another piece of paper or cloth with a thickness of 0.3 to 0.5 mm into a pad slightly larger than the original sealing ring and install it in the groove, then install the original sealing ring.
