500 tons of electric hydraulic jack price how much?
Hydraulic jacks are divided into electro-hydraulic jacks and large-tonnage hydraulic jacks. Hydraulic jacks are equipped with a pump and jack with a unit price of 23,760 yuan/set. Electro-hydraulic jacks are called electro-hydraulic jacks. The electro-hydraulic jacks have large output and light weight. The features of long-distance operation, together with our ultra-high pressure electric oil pumping station, can achieve top, push, pull, squeeze and other forms of operation, widely used in construction engineering, shipbuilding, metallurgy, mining, petrochemical, Railway engineering, and other industrial operations such as jacking, stretching, and squeezing. In recent years, it has been widely used in foundation settlement tests and static pressure piles.
The 500-ton electro-hydraulic jack price is a new type of multi-purpose tool consisting of an oil pump and a roof. It can perform work such as starting, top lifting, straightening, bending, and pressure testing. It has a compact structure, simple operation, easy use, and safety. Fast loading and unloading are suitable for factories, oil fields, ships, docks, warehouses, railway buildings, and scientific research.
Instructions:
1. Fit the joint of the high-pressure hose on the oil pump and the joint on the jack, and then tighten the oil drain screw on the oil pump jack. After use, after the work is completed, loosen the above-mentioned screw and restore it to the original state.
2. When the oil pump is to be refueled, the screw at the rear of the oil pump can be removed to add oil, and the oil should be kept clean.
500-ton electro-hydraulic jack Note:
1. The oil pump should be replenished if there is an empty phenomenon.
2. If there is a long time unloading, you need to install a pressure relief valve, and then drain the oil pump screw. Pulling out the joints on the high pressure pipe can be achieved without dropping the rest.
3. Connect the high pressure pipe on a pressure-free basis.
500 tons electro-hydraulic jack troubleshooting and maintenance methods - RONGMEI main reasons for troubleshooting the piston does not rise 1, the oil pump station does not supply oil.
2. The upper and lower chambers of the fuel tank or the left and right chambers of the hydraulic check valve are damaged and communicate. 1, maintenance oil pump.
2, exchange O-rings, retaining ring.
The pressure rises and the piston does not rise 1. The quick connector or the hose is littered or damaged and the tubing is blocked. 1. The motor should be shut down immediately. Check the clean joint or replace the parts. Blow off the hose and other channels with compressed air.
Lifting weight down 1, hydraulic check valve seal gasket damage.
2, the sealing element wears and leaks. 1, exchange seals.
2, exchange the sealing element.
No increase in piston lift, excessive load or partial load, permanent deformation of the piston.
(1) Exhaust device adjustment. First, the working pressure in the cylinder is reduced to about (0.5-1) MPa, then the piston rod is reciprocated, and the exhaust plug is opened to exhaust. The method of opening is: When the piston reaches the end of the stroke, the vent plug opens at the moment the pressure rises, and closes immediately before starting to return. When the exhaust plug is exhausted, the squeaky sound of the snoring can be heard, followed by the turbidity of the foamy oil. When the exhausted air is exhausted, the oil is clarified. You can use the naked eye to determine if the exhaust is complete.
(2) buffer device adjustment. In the case of an adjustable cushioning device with the piston in motion, the throttle valve should be placed in a relatively small flow position, and then the orifice size should be gradually adjusted until the requirements are met.
(3) Inspection of various parts of hydraulic jacks. In addition to the above-mentioned adjustment work, hydraulic jacks also inspect the oil leakage of each seal, and whether the bolts of the connected parts are loose or not to prevent accidents.
(4) Regular inspections. According to the use of hydraulic jacks, arrange regular inspections and make inspection records.
The hydraulic jack components have gradually achieved standardization, serialization and transformation, and their specifications, varieties, quality and performance have been greatly improved. Especially after adopting new technologies such as electronic technology and servo technology, the quality of the hydraulic system has been significantly improved. The improvement has played a major role in the national economy and military industry.
Hydraulic jacks can be divided into different forms from different perspectives.
(1) According to the circulation of oil, the hydraulic system can be divided into open system and closed system. The open system refers to the hydraulic pump sucks oil from the fuel tank. After the oil passes through various control valves, the hydraulic actuator is driven, and the return oil passes through the reversing valve to the fuel tank. This kind of system structure is relatively simple, can exert the heat dissipation of the oil tank, the function of depositing the impurity, but because the oil is often in contact with the air, make the air easy to infiltrate into the system, cause the mechanism to move unsteadily and so on the result. The open system tank is large and the oil pump has good self-priming performance. In the closed system, the inlet pipe of the hydraulic pump is directly connected to the return pipe of the actuator, and the working fluid is closed and circulated in the pipeline of the system. Its compact structure, with less chance of contact with the air, air is not easy to infiltrate into the system, so the transmission is more stable. The variable speed and commutation of the working mechanism are realized by adjusting the variable mechanism of the pump or the motor, avoiding the hydraulic shock and energy loss occurring in the process of the reversing of the open type hydraulic jack. However, the closed system is more complex than the open system because of the lack of fuel tanks and poor heat dissipation and filtration conditions. To compensate for leaks in the system, a small flow charge pump and fuel tank are usually required. Due to the unequal flow rate of the single-rod double-acting cylinders, the power utilization will be reduced during the working process. Therefore, the actuators in the closed system are generally hydraulic motors.
(2) According to the number of hydraulic pumps in the system, it can be divided into single pump system, double pump system and multi pump system.
