Angola hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Angola spring return cylinder,produced by Hebei Hengyu company）

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

Introduction to spring return cylinder:

spring return cylinders in series, parallel and series parallel. Series: In the spring return 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 spring return 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 spring return 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 spring return 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.

The definition of the minimum stable speed refers to the minimum movement speed of the spring return cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the spring return cylinder that undertakes different work has different requirements for the minimum stable speed.

When the hydraulic oil is not pumped into the spring return cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the spring return cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

When the piston speed of the spring return cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the spring return cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about spring return cylinder:

How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.

What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
