As a city construction and fire standby equipment, mobile pump trailers are innovative technology products that we often use and see. We will tell you the operation process when pumps were delivered from the factory and received by customers. However, how many do you know about the maintenance of mobile pump trailers? Let’s learn about the maintenance of the mobile pump trailer.
1. Pumping mechanism part
Before using the car, fill the washing room with clean tap water. When the outside temperature is lower than 30 degrees, you can add about one-third of the waste hydraulic oil to increase the lubrication effect!
- After the pumping is completed, screw the open water rubber block, discharge the water in the washing chamber, and remove the piston for cleaning and inspection;
- keep the washing room clean, the cylinder rod is not allowed to deposit dirt.
- When it is found that the water in the washing chamber is turbid, the sealing body should be replaced;
- When the water temperature is too high during the pumping process, please change the water in time.
2. S tube and agitator shaft lubrication
- Maintain good lubrication of the agitator shaft and the size of the bearing housing. Good lubrication can increase the service life of the parts (the labor intensity during maintenance is very high). In summer, use the “00” non-pressure and semi-fluid lithium grease. In order to ensure its fluidity under low-temperature conditions, please use “000” type lithium grease in winter.
- Automatic lubrication method, it is required to check the oil level in the oil tank at all times, timely refueling and observes the working state of the grease distribution valve behind the hopper. The long-term overflow of the pointer indicates that the lubrication point is blocked, such as the long-term overflow of the pointer during the pumping process. Please remove the grease tube to avoid other lubrication points and block it together. After the work is finished, clean and clear the oil line that blocks the lubrication point.
- When filling the grease, keep the filling container clean and do not allow dirt (such as wood chips, paper scraps, etc.) to enter the lubrication system.
3. hopper inspection
- After the pumping is completed, the hopper should be cleaned up, and there should be no accumulation of materials. Otherwise, the lower part of the S tube may be worn or worn away.
- Each time the pumping is completed, the hinged elbow must be opened to clean the recess in the S tube to prevent the next pumping from being blocked!
- Check the gap between the cutting ring and the glasses plate every day, to check whether the cutting ring is damaged. The cutting ring is easy to wear on the two sides in the moving direction because it needs to be cut in the reciprocating motion of the S tube. It only protects the wear-resistant electrode part of the hard alloy surfacing. When it is found to be worn, please turn the cutting ring down 90° in time. You can remove the cutting ring and use the 707 electrodes for surfacing, so you can reduce the cost.
- The wear of the mixing blade will cause the suction of the pump to be poor, and the accumulation of material at the bottom of the hopper will increase. Please change the mixing blade in time. If you want to weld the mixing blade, keep the distance between the blade and the hopper wall not less than 5 cm. Otherwise, it will cause the hopper to wear through.
- The transition part between the glasses plate and the conveying cylinder is equipped with a transition sleeve. Please check frequently. If the wear is severe, the height is lower than the conveying cylinder. Please change the transition sleeve in time, otherwise, it will affect the life of the conveying cylinder.
- It is strictly forbidden to wrap the stirring motor. Check the observation hole of the stirring motor base every day to check whether it leaks.
4. Reducer
- The speed reducer is filled with viscosity. The dosage is about 4 liters. It is required to change for 500 hours or half a year.
- (Monthly) Unscrew the vent hood and check the oil supply through the oil connection and the oil pipeline to prevent oil shortage.
- Apply grease to the surface of the gear in the rotary reduction mechanism every month.
- Lubricate the slewing bearing with a grease gun per 15 days through the grease fitting on the fueling seat.
5. Reducer maintenance steps
- Let the rotary reducer work for a period of time, the temperature rises by 30 degrees, unscrew the reducer oil drain screw plug, run the old oil off, and tighten the screw plug!
- Clean the area around the reducer with a cloth.
- Unscrew the vent cover and the oil level screw plug and fill the oil through the oil filler joint (about 4 liters) until the oil hole has clean oil out.
- Tighten the oil level screw plug and cover the ventilation cover.
