Norway sanitation truck hydraulic cylinder

(Norway sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

sanitation truck hydraulic cylinder are widely used in Norway,because of long service life,smooth movement,high work efficiency.So our company has designed sanitation truck hydraulic cylinder for customers from Norway.

Introduction to sanitation truck hydraulic cylinder:

The sanitation truck hydraulic cylinder should be used correctly and maintained regularly. The sanitation truck hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the sanitation truck hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Regular maintenance of the sanitation truck hydraulic cylinder includes: regular tightening, sanitation truck hydraulic cylinder fastening screws and gland screws, sanitation truck hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the sanitation truck hydraulic cylinder once a year. Clean regularly, the sanitation truck hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

If the sanitation truck hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the sanitation truck hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow sanitation truck hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the sanitation truck hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the sanitation truck hydraulic cylinder includes the leakage caused by excessive wear of the sanitation truck hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and sanitation truck hydraulic cylinder, and the phenomenon of "pulling the sanitation truck hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

sanitation truck hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the sanitation truck hydraulic cylinder head itself is the guide sleeve of the piston rod, the sanitation truck hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the sanitation truck hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Answers to some questions about sanitation truck hydraulic cylinder:

How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
