Introduction and parameters

Introduction of pump car products:

  Pump Truck It is a machine for continuously conveying concrete along the pipeline by pressure. It is composed of pump body and conveying pipe. It is divided into piston type, extrusion type and water pressure diaphragm type according to structure. The pump body is mounted on the chassis of the vehicle and equipped with telescopic or folding cloth poles to form a pump truck.
Pump maintenance method:
 
1, pump maintenance methods should be in accordance with the corresponding requirements and methods in the maintenance manual, daily use, before and after the pump car related items for inspection.

2. According to the corresponding requirements and methods in the service manuals, refer to the lubrication table to make timely and adequate lubrication for all parts of the pump truck.
 
3. According to the corresponding requirements and methods in the maintenance manual, select the specified type of hydraulic oil and replace the oil in the hydraulic system regularly.
 
4. According to the maintenance methods and requirements of the concrete pump truck in the manual, check the water tank, concrete cylinder and concrete conveying pipe of the pumping system regularly.
 
5. According to the corresponding requirements and methods in the maintenance manual, periodically check and adjust the torque of the fixed bolt of the boom base.
 
6. According to the maintenance method of concrete pump truck in the manual, regular inspection and adjustment of jib, rotating base, outrigger, supporting structure, reducer and other components.
 
7, according to the corresponding requirements and methods in the maintenance manual, regularly check the working state of hydraulic system and components, electrical systems and components.
Safety inspection for pump truck Construction:

1. regularly check the fastening parts of the pump truck: because of the vibration impact and uneven load of the diesel engine and the gasoline engine, the bolts and nuts are easy to loose. And all parts of the adjustment bolts must be checked, so as not to cause the cause of loosening and damage to the body.

2. correctly use the engine: before the pump is running, lubrication parts such as bearing shells should be lubricated. After starting, the water temperature should reach 40 C -50 C. Long term overload or low speed operation is strictly prohibited. Before unloading, load and speed should be removed first. After parking in winter, when the water temperature drops to 40 -50 C, the cooling water will be discharged. At ordinary times, the engine maintenance should be done regularly so that the machine will always be in good condition. We should observe and check frequently, find faults and eliminate them in time.

3. ensure sufficient oil, water and air: diesel oil, gasoline and air supply are not timely or interrupted. There will be difficulties in starting pump trucks, poor combustion, reduced power and engine failure. If the oil supply is insufficient or interrupted, the engine will not lubricate properly, and the body will wear badly or even burn. If the cooling water is insufficient, the machine temperature will be too high, the power will decrease, the wear will be intensified, and the service life will be reduced.


Matters needing attention in the use of pump cars:

(1) check the adequacy of engine oil, cooling water, clutch fluid, hydraulic oil and cleaning water. The control rods of concrete pumps should be placed in the middle position. Obey the driving rules. ·
(2) when the concrete pump truck arrives at the construction site, it should be put on the horizontal dense ground. It is not allowed to park on the slope to prevent the occurrence of automatic sliding.
(3) the lower part of the front and rear legs of the pump truck should be padded with thick planks, so that each leg can be evenly stressed and reduce the pressure on the ground. After stopping, the two front wheel of the pump truck touchdown to relieve the load of the front leg oil cylinder and increase the stability of the pump truck.
(4) when the concrete is vertically pumped, the horizontal pipe between the pump outlet and the vertical riser must be 10m long.
(5) the pump boom is usually made of three folding arms. In the transportation state, the three boom is tortuous back and forth. When the site is moving short distance, the third boom is pulled back, the one or two boom is moved to the rear of the pump and lowered to the horizontal position, and the slewing supporting device of the cloth bar is locked to allow the pump to move slowly at the speed below 10km/h, so as to ensure the stability of the pump when it moves. Of course, all the arms are contracted back and then moved.
