(Summary description)As a professional pipe jacking machine manufacturer, the pipe jacking machine produced by our company is mainly composed of hydraulic pump station, hydraulic cylinder and high-pressure hose. It has the advantages of convenient operation and simple operation. It is an ideal jacking machine. 1. The main structure of the product: 　　 The device is mainly composed of a hydraulic pump station, two main jacking cylinders, four outrigger jacking cylinders, high-pressure hoses, oil pipe joints, etc. 　　1. The jacking cylinder is mainly composed of a cylinder block, a piston rod, a piston ring, a joint cap, and a seal. 2. The hydraulic pump station consists of an oil tank, an axial variable plunger pump, a three-phase asynchronous motor, an electromagnetic reversing valve, an overflow valve, a hydraulic control check valve, a valve bottom plate, an air filter, an oil suction filter, and an electric control box And other composition. 　　3. The high-pressure hose adopts threaded joints for easy connection and disassembly. 2. How to use: 　　 1. Connect the high pressure hoses of the pumping station to the upper and lower cylinders of the six jacks. When connecting, pay attention to not connect the designated position wrongly, otherwise the jack will not work. 　　 2. Turn on the power supply: power supply 380V/50HZ, pay attention to grounding. 　　 3. No-load test run: the oil pump motor is divided into forward and reverse rotation, press the jacking button, the oil cylinder should be lifted, if the motor can not be lifted by rotation, the motor may reverse and require phase adjustment. 　　4. The hydraulic oil used in this equipment is N46# hydraulic oil in summer and N32# hydraulic oil in winter, which is replaced every 1000 hours. 　　5. High-pressure hose: High-pressure test before leaving the factory. The test pressure is 35Mpa. Due to long-term use, it will deteriorate and deteriorate and reduce the strength. Pay attention to regular inspections, usually once every six months. Frequent users should pay attention to the phenomenon of convex cracks and leakage. If leakage, bulging or rupture is found, the hose should be replaced in time. The hose should avoid bending and sharp bends during use to ensure the service life of the hose. 　　 6. Load work: Fix the cylinder to the device to be installed. Press the main lift button, the two main lift cylinders simultaneously lift and lift the belt conveyor, press the main down button, the two main lift cylinders descend and lower the belt conveyor at the same time; press the outrigger extension button, four outriggers to lift the piston rod of the cylinder Extend at the same time until it is in full contact with the ground, and press the outrigger retraction button. The piston rods of the four outriggers to lift the cylinder are simultaneously retracted and separated from the ground until the cylinder is completely retracted.
