Embodiment Construction

[0035] Embodiments of the present invention will be described with reference to the drawings. In addition, the embodiment is an example of the invention and does not limit the invention, and all the features and combinations described in the embodiment are not necessarily the essence of the invention.

[0036] The compressor of this embodiment is equipped with a locking piston in which a piston rod 11 is accommodated in a cylinder 10, and by accumulating air compressed by the locking piston in a compressed air storage tank (not shown), it can be supplied to a nailing machine or the like. Supply compressed air.

[0037] The lock piston is operated by a motor 30 provided inside the compressor, and the motor 30 operates a crank mechanism (not shown), so that the piston rod 11 reciprocates in the cylinder 10 to compress air.

[0038] Such as figure 1 As shown, the piston rod 11 is formed to be slidable while rocking in the air cylinder 10 , and a disc-shaped piston portion is fo...

Abstract

The invention provides a compressor, comprising: a motor (30); a piston rod (11) that uses the motor (30) to reciprocate in a cylinder (10); A sealing member (14) for sealing between them; a cold state determination unit (110), configured to determine whether the compressor is in a cold state; When the machine is in a cold state, the rotational speed of the electric motor (30) is controlled in such a way that the rotational speed of the electric motor (30) is increased to perform warm-up operation.

Description

technical field [0001] The present invention relates to a compressor and a method for operating the compressor. Background technique [0002] Conventionally, as a piston used in a compressor, a lock piston reciprocating while swinging in a cylinder using a connecting rod connected to a crankshaft is known. In such a lockup piston, a lip ring is provided as a sealing member at the tip of the piston rod, and the cylinder and the piston rod are sealed by the lip ring (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 09-068279 [0004] The lip ring, which is such a sealing member, changes in size due to thermal expansion. Therefore, when the compressor becomes cold, the lip ring shrinks and cannot exhibit sufficient sealing performance. Therefore, the sealing performance of the lip packing will decrease when the operation is stopped for a long time or when it is used in a cold place. [0005] In addition, the lip ...
