The hydraulic system is an important part of the sealed garbage truck. Whether the hydraulic system is working properly determines whether the garbage truck can operate normally, so the daily maintenance and maintenance of the chess hydraulic system is very important. If the hydraulic system of the sealed garbage truck fails, how can we solve it? The following Xiaobian share some treatment methods on this issue.
1. When the sealed garbage truck hydraulic system is not working properly, check the power take-off first to see if it is properly meshed. In addition, check whether the hydraulic oil in the tank is sufficient and whether the suction pipe ball valve is fully open.
2. The hydraulic system of the sealed garbage truck has the action but no power. Check whether the gear oil pump fails and whether the system pressure reaches the specified value.
3. The action of the hydraulic mechanism of the sealed garbage truck becomes slow, check whether the gear oil pump fails, whether the oil sucking oil filter and the oil returning oil filter core are plugged.
4. The hydraulic mechanism of the sealed garbage truck has no action. Follow the steps below to check it.
aã€Whether the amount of oil in the hydraulic tank is sufficient. When insufficient, hydraulic oil should be added;
b. Observe whether the oil inlet pipe from the fuel tank to the oil pump will cause the oil sucking phenomenon due to aging. If this is the case, replace the inlet tube.
c. Check if the gear pump fails. Put a pressure gauge, turn the pressure regulating bolt, and observe whether the table has reached the specified value;
d. If the pressure regulator bolt fails to reach the specified hydraulic pressure after it is fully screwed in, the gear oil pump will fail and the gear oil pump must be replaced;
e. If the gear oil pump is working properly, it is the clogging of the multi-way valve spool. The valve plug should be removed to remove impurities and used after reinstalling.
5, after the above conditions are still excluded after the exclusion of the reasons, or damage to the hydraulic parts, it should be informed of professional personnel maintenance, unauthorized disassembly.
The above is the solution to the failure of the sealed garbage truck hydraulic system. Usually in the course of use, the owner's friends should also do maintenance work on the hydraulic system in time, which can also reduce the occurrence of failures. Finally, users should be reminded that the pressure regulating device of the hydraulic system is a pressure regulating bolt on the multi-way valve. After the bolt is calibrated and locked tightly, it cannot be arbitrarily moved. It is also not allowed to adjust the oil pressure.
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
