Relevant Information of 30 Ton Manual Hydraulic Jack
 Manual hydraulic jack is tonnage size, travel is not equivalent to different prices. How much is a 30-ton manual hydraulic jack? Price: 1150 yuan per set. Technical parameters are as follows: 30-ton manual hydraulic jack load 30T, working stroke:150 mm, body height: 280 mm operation mode: manual hydraulic operation.          
 Hydraulic jack is a new type of multi-purpose tool. It is composed of oil pump and jack. It can carry out lifting, lifting, straightening, bending and pressure test. It has the characteristics of compact structure, simple operation, convenient use, safety and fast loading and unloading. It is equally suitable for factories, oilfields, ships, wharfs, warehouses, railway buildings and scientific research. Applicable.           
 Manual hydraulic jack features:           
 Manual hydraulic jack equipped with various accessories has many functions, such as lifting, jacking, shoveling, splitting and so on. It can be installed quickly by using quick joint.            

 Manual hydraulic jack is safe to use, and oil pump can unload automatically when overloading.           
 Manual hydraulic jack tool is light, easy to use and carry.           
 Manual hydraulic jack and oil pump adopt compound structure. When no-load, the flow is  large, the speed is fast, and when heavy load, the flow is small and the speed  is slow.            

 Use method of manual hydraulic jack:           
 1.  Cooperate the joint of the high-pressure rubber hose on the oil pump with the joint of the jack, and then tighten the discharging screw on the jack of the oil pump separately. Even if the screw is used, the screw will be loosened after the work, so that it can be restored to its original state.
 2.  If the pump needs to refuel, the screw at the end of the pump can be removed to refuel, and the oil should be kept clean.           
 Notes for manual hydraulic jack:           
 1.  If the pump has suction phenomenon, it should be supplemented with oil.           
 2.  If there is a long time unloading, it is necessary to install pressure retaining valve, and then the drain screw on the turpentine pump. Pull out the joints on the high-pressure pipe and keep the rest of them still, so as to achieve the goal of not falling down.           
 3.  Connect the high-pressure pipe on the basis of no pressure.           
 When the piston does not rise, first check that there is no oil supply at the pump station.            

When the seal of the upper and lower chambers of the cylinder or the left and right chambers of the hydraulic control one-way valve is damaged, the connection will occur. First, repair the oil pump. Secondly, replace O-ring and baffle ring. When the  pressure rises and the piston does not rise, the reason may be that there is rubbish or damage in the quick joint or hose which blocks the pipeline. The motor should be closed immediately to check the clean joint or replacement parts, and the hose and other channels should be blown clean with compressed air. When the lifting load drops, it may be that the sealing gasket of the hydraulic control one-way valve is damaged or the sealing elements are worn out, resulting in leakage. First replace the gasket, then replace the sealing element.            

When the piston lifting capacity can not be lowered. The piston should be deformed due to overload or eccentric load. The second reason is that the pipeline is blocked. The third reason is that the one-way valve stem does not push the ball away. The first step is to repair or replace the piston. The second step is to close the motor immediately, check the clean joint or replace the parts, and clean the hose with compressed air. The third step is to change the valve stem.           
 The above comprehensively explains the price and characteristics of manual hydraulic jack, its usage and routine malfunction. Welcome to pay attention to the company's development. Here we provide you with newer information and high-quality service. We look forward to cooperating with you.
