(Ecuador plunger type cylinder,produced by Hengyu Group）
plunger type cylinder are widely used in Ecuador，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed plunger type cylinder for customers from Ecuador.
Regular maintenance of the plunger type cylinder includes: regular tightening, plunger type cylinder fastening screws and gland screws, plunger type 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 plunger type cylinder once a year. Clean regularly, the plunger type cylinder is cleaned every other year, and the seals are replaced while cleaning.
plunger type cylinder hydraulic oil selection: The recommended working oil viscosity of the plunger type cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The quality of the plunger type cylinder can not be ignored in the purchase of the plunger type cylinder. The plunger type cylinder is the main component of the plunger type cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. plunger type cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of plunger type cylinder is deep hole processing, which has always troubled the processing personnel.
The main role of the plunger type cylinder: the plunger type cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the plunger type cylinder realizes reciprocating motion. The structure of the plunger type cylinder has three categories: piston plunger type cylinder, plunger plunger type cylinder, swing plunger type cylinder, piston plunger type cylinder and plunger plunger type cylinder to achieve reciprocating linear motion, output speed and thrust, swing plunger type cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the plunger type cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The plunger type cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
