Fire pump maintenance and maintenance I. Hand-held mobile fire pump maintenance
1. The hand-lifting mobile fire pump must be kept clean and complete, and the external dust and oil should be removed after each use. Check that the parts are complete, that the joints are tight and that they are ready for repair.
2. Check the oil level in the crankcase. When it is insufficient, it should be added to the oil mark. If the oil is insufficient or the oil quality is not good, the oil shaft, connecting rod, piston, gas valve and other parts of the gasoline engine will be used. Special care should be taken when severe wear and tear can cause major accidents.
3, the water-absorbing hose can not be excessively bent and placed on the heavy objects on it, from cracking and flattening, the gasket in the water-absorbing hose joint can not be lost and damaged, otherwise it will cause difficulty in water diversion, and even lead to water.
4. Check if the governor connection parts are flexible.
5. Eliminate the faults and abnormalities found in time.
Second, hand-lifting mobile fire pump maintenance
1. Check the air filter element to remove debris and keep the filter clean. Check the fastener bolts and do not allow looseness. Check if the oil level is within the specified range. Check for oil in the vane pump oil cup.
2. The air filter element must be cleaned after the working time reaches 25 hours.
3. For every 50 hours of work, the spark plug must be removed, check the gap, and adjust the gap to 0.6-0.7mm. Check the heat sink to remove dirt between the heat sinks. Replace the lubricating oil, loosen the oil drain bolt, slightly tilt the engine, let the oil flow out slowly, add the oil to clean, wait until the oil is dry, tighten the oil drain bolt, and add clean oil from the oil filling port to the specified height. (Note: The new machine has been used for 5 hours, and the oil must be replaced once. The amount of one time is 1.1 liters.)
4. The fuel tank and fuel filter net must be cleaned every 100 hours of operation. Open the fuel tank cap, take out the filter net, gently scrub with a brush, remove the fuel tank, clean the inside of the fuel tank, remove the dirt and moisture attached inside, install the fuel tank, put the filter at the injection port and add new fuel. Until the red baseline.
5. Check the aging of the fuel pipe every two years. If it is found that it is aging, hardening or cracking, it must be replaced. After replacing it, tighten the joint to check for oil leakage.

80m Electric Laser Distance Meter
Building measurement is the first and most important process of building construction. With the development of society, there are more and more high-rise buildings. In the process of construction and future floor decoration, the measurement of the height of the building, the distance between two points, the area, etc., the materials used for the floor, the structural orientation, etc., are all related to the whole Safety of floor buildings. At present, the most commonly used measurement tools include various rangefinders, laser rangefinders, telescope rangefinders, etc. The use of these measurement tools can reduce the measurement error and make the measurement more accurate. The company's Laser Rangefinder has been successfully used in the construction industry.
The laser rangefinder is small in size, light in weight and easy to carry. The measuring range is 0.05-80 meters, and the error is only plus or minus 2 mm. It can easily measure the area and volume.
Its large LCD backlit display makes it easy to read out the measurement data. In addition, it is simple and safe to use. It only needs one person to operate and does not need to use other tools (such as ladders, etc.) to complete all measurement operations. Even difficult-to-reach parts can be easily dealt with, thereby avoiding injury accidents on a large level. happened.
