Bahrain hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder

(Bahrain trunnion cylinder,produced by Hebei Hengyu company）

trunnion cylinder are widely used in Bahrain，because of no transmission clearance，powerful torque，excellent temperature resistance.So our company has designed trunnion cylinder for customers from Bahrain.

Introduction to trunnion cylinder:

How to repair the trunnion cylinder body when it is damaged: When the trunnion cylinder has trace deformation and shallow tensile marks, the trunnion cylinder is repaired by strong honing process. The heavy honing process can repair trunnion cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the trunnion cylinder can meet the technical requirements.

trunnion cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the trunnion cylinder head itself is the guide sleeve of the piston rod, the trunnion 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 trunnion cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

When the trunnion cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the trunnion cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Classification of trunnion cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

Answers to some questions about trunnion cylinder:

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.

Why the injection cylinder retreating after the injection molding machine is started?
It is likely that the projected area of the molded plastic parts is large or the injection pressure set is relatively large, resulting in the expansion force exceeding the clamping force of the injection molding machine, so the mold is backward. You can do the following attempts: 1, reduce the injection force of the injection molding machine; 2, if the injection molding part can not be well formed by reducing the injection force, it is recommended to install the mold to a larger injection molding machine.
