Each hydraulic jack is a stiffness lifting parts, and the lifting parts of the hydraulic jack is the choice of piston pump and hydraulic system. Hydraulic jacks have strong bearing capacity, super heavy and even can carry 100 tons of net weight, and in the process of adoption must pay attention to some corresponding matters.

A. Play empty situation to solve

In fact, the specification of the gearbox jack is very easy to deal with. In this case, we must only loosen the screw with some oil on the pump shell, then shake the pump shell down with strength, blow the head vertically down in the air, and then tighten the screw, and you can apply it again.

Two. Cargo problem

In the case of adoption, I want to have bias or overpressure, otherwise it is likely to lead to the destruction of hydraulic jacks and risk. In the case of load, do not learn to put down the conversion head, to prevent safety accidents or the destruction of parts.

Three. Key problems

Liquid hydraulic jack application of the substance is oil, so in order to make its effect is the best, we must carry out excellent maintenance of oil, to avoid oil blocking and oil seepage. Some hydraulic jacks, its hydraulic system has a lot of gas, in the beginning of the selection of the case, it is likely to produce some small jump, mainly because it has not been applied for a long time. It is also very easy to handle, just fill it with a full load two or three times and exhaust the gas. Long-term has not been applied to the equipment, because of the sealing and its long-term does not work, and the occurrence of hard bottom, this kind of situation will cause the service life of the hydraulic jack is greatly reduced. Therefore, if you want to use it for a long time, remember to run it several times with a full load.

Four. Maintenance problems

1. Hydraulic jack application, bottom to pad leveling, with no oil stains of wood bearing capacity to expand the total bearing area, can ensure safety, can not use stainless steel plate, prevent deviation.

2. When rising, it should be stable. After rising a little, it should check whether the situation is safe or not, and there is no abnormality such as rolling.

3 if there are more than one hydraulic jack at the same time the actual operation, must be configured to guide the staff, so that the equipment with the same rise and fall, convenient operation, and the adjacent hydraulic jack, in the middle of the need to put the support point of the baffle, or smooth wood, to avoid rolling.

The application of hydraulic jacks must be understood
