Kuwait hydraulic cylinder,sanitation truck hydraulic cylinder manufacturer,sanitation truck hydraulic cylinder(Kuwait sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
sanitation truck hydraulic cylinder are widely used in Kuwait,because of long service life,smooth movement,high work efficiency.So our company has designed sanitation truck hydraulic cylinder for customers from Kuwait.
Factors that should be considered when selecting the oil seal in the sanitation truck hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the sanitation truck hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: sanitation truck hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, sanitation truck hydraulic cylinder working pressure, sanitation truck hydraulic cylinder movement speed, hydraulic system oil temperature and sanitation truck hydraulic cylinder working environment.
sanitation truck hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching sanitation truck hydraulic cylinder block - fine boring sanitation truck hydraulic cylinder block - grinding sanitation truck hydraulic cylinder block. The rolling method is: broaching sanitation truck hydraulic cylinder block - fine boring sanitation truck hydraulic cylinder block - rolling sanitation truck hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the sanitation truck hydraulic cylinder block is about 1-2 days, rolling 1 meter of the sanitation truck hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the sanitation truck hydraulic cylinder increases by 25%. If the sanitation truck hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality sanitation truck hydraulic cylinders, you must take the rolling production process. After the sanitation truck hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.
sanitation truck hydraulic cylinders in series, parallel and series parallel. Series: In the sanitation truck hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the sanitation truck hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the sanitation truck hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the sanitation truck hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.
Before purchasing the sanitation truck hydraulic cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.
How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
