(Algeria plunger type cylinder,produced by Hebei Hengyu company）

plunger type cylinder are widely used in Algeria，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed plunger type cylinder for customers from Algeria.

Introduction to plunger type cylinder:

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.

When the initial action of the plunger type cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the plunger type cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

If it is found that the plunger type cylinder lubrication is poor or the plunger type cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the plunger type cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the plunger type cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the plunger type cylinder center line. In this way, when the piston works in the plunger type cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the plunger type cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

After the plunger type cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

Answers to some questions about plunger type cylinder:

Injection molding machine die thimble on the side of the feed nozzle, the oil cylinder pull the thimble shift, how to debug the oil cylinder?
The cylinder is connected with the neutron of the injection molding machine, the neutron is retreated after the opening mold is in place, the cylinder taps the thimble plate to the top, and then takes, and the neutron is reset.

How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
