Regular maintenance is required for fire pumps. In particular, the lubricating oil in the bearing must be replenished in time to ensure that the oil level is correct before normal operation.
So, how is it right to refuel the fire pump? Today, Better Technology explains the customer's concerns: How to properly refuel the fire pump, the standard instructions are here!
When does the fire pump need to refuel?
In general, the fire pump is capable of normal operation and its normal oil level should be within 1/3-2/3 of the equipment oil level window or indication. Generally, the oil level shown in the oil cup we see only represents the capacity of the oil, and the oil level of the bearing of the fire pump is to meet the operating requirements. When the oil level in the oil cup is lower than 1/4 of its total volume, Need to consider the replenishment.
How to correct the fire pump?
Step 1: Use Qualified Oil
It is recommended that competent enterprises and institutions carry out oil testing before replenishing oil. The specific method is to use a small amount of lubricating oil as a sample for comparison with fresh lubricating oil, and it can be used only after verification according to relevant standards.
1. If the sample looks cloudy, it may be the result of mixing with water, which is often referred to as oil emulsification. Such a lubricant is not acceptable.
2. If the sample appears dark or thick, it may indicate that the lubricant has begun to carbonize and is not acceptable.
Lubricating oil is a mixture of complex hydrocarbons. It is a liquid or semi-solid lubricant that is used in various types of automobiles and machinery to reduce friction and protect machinery and piecework. It is mainly used for lubrication, cooling, rust prevention, and cleaning. Sealing and buffering functions. Fresh, qualified lubricants are generally tested by professional systems, obtained relevant certificates, have a certain protection of the brand effect, simple verification can be seen by the viscosity, smell smell, which viscosity, moisture, etc. should meet the national standards.
Step 2: Make effective replacement according to the operating environment of the fire pump
If the environment or operation of the fire pump causes the oil temperature to be below 60°C, and the oil is not contaminated, replace the oil once a year; if the oil temperature is between 60-100°C, replace the oil four times a year; The oil temperature is 100-120°C. It is recommended to change it once a month. If the oil temperature is above 120°C, it needs to be replaced every week to ensure normal operation.
